The closest living ancestors of birds are crocodilians. What provides morphological evidence for this relationship?
a) both are homeothermic
b) both have extensive air sac system
c) both have a 4-chambered heart
d) both have differentiated teeth
e) none of the above
Answer:
c) both have a 4-chambered heart
Explanation:
The heart that consists of four chambers where the blood flows. In this, the blood entered into the right atrium and passes via the right ventricle. Now the right ventricle pumps the blood into the lungs in which it is oxygenated. Now the oxygenated blood would be bring back to the heart via the pulmonary veins that entered into the left atrium
So as per the given situation, the option c is correct
Compare and contrast the advantages and disadvantages of wind power and geothermal power
Answer:
An Overview of Geothermal Pros and Cons:
Pros Cons
This energy source is more environmentally friendly than conventional fuel sources. The largest single disadvantage of geothermal energy is that it is location specific.
A source of renewable energy. Gases are released into the atmosphere during digging.
The number of exploitable geothermal resources will increase with ongoing research and development in the industry. Geothermal energy runs the risk of triggering earthquakes.
A sustainable source of energy as its always available unlike wind and solar. Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.
A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
No fuel is required.
Increase in exploration meaning that new technologies are being created to improve the energy process.
Pollution levels are much lower compared to fossil fuels.

You have a novel virus that can kill mice when injected into them. This novel virus can transform a non-virulent virus, causing it to become virulent. You want to understand what the transforming factor is made of. You heat kill the novel virus and treat different samples of the heat killed sample with either an RNase, a DNase, or a Proteinase. Of the novel virus uses double-stranded RNA as its genetic material, which treated sample will no longer be capable of transforming the non-virulent strain
Answer:
The sample treated with RNase
Explanation:
According to this question, a novel virus was found which was capable of killing mice when injected into them and capable of making a nonvirulent virus to be virulent by transforming them.
After heat killing the novel virus, different samples were treated with either an RNase, a DNase, or a Proteinase. If the novel virus uses double-stranded RNA as its genetic material, the sample treated with RNase will no longer be capable of transforming the non-virulent strain. This is because RNase is a catalytic enzyme that degrades RNA, hence, the RNA will no longer be present to transform.
Type of cell division that is occurring in the cell in the diagram
Answer:
There is no diagram but the cell division happens in stages. PMAT is a way to remember them. prophase, metaphase, anaphase, and telophase. This all takes place in Mitosis. Mitosis is the division of cells to make more *identical* cells, (skin cells, stomach cells). But Miosis is the making and division of sperm cells *not Identical* (sperm, and egg cells) are made in this phase.
why do we find tea to be tasteless after we have eaten sweet or candies

(c) Predict the growth rate pattern of the E. coli-M bacteria when they are initially added to the growth medium if the mutation does not interfere with glucose utilization.
(d) Provide reasoning to justify your prediction.
The question is incomplete. The complete question is :
Glucose is the preferred carbon source for Escherichia coli bacteria. Researchers isolated E. coli-M, a strain of E. coli with a single mutation that inactivates a key enzyme in one of the three glycolytic pathways E. coli bacteria use to break down glucose. In an initial experiment to study the effect of the mutation on glucose utilization and ATP production by the bacteria, the researchers add 2×104 E. coli-M bacteria to 400 mL of a growth medium that contains glucose. To measure the rate of bacterial growth, they monitor the optical density of the culture as a measure of bacterial concentration over time.
(c) Predict the growth rate pattern of the E. coli-M bacteria when they are initially added to the growth medium if the mutation does not interfere with glucose utilization.
(d) Provide reasoning to justify your prediction.
Solution :
c). It is given that Glucose is preferred as the carbon source for the Escherichia coli bacteria or the E. coli-M bacteria. If the growth medium of the E. coli-M bacteria contains a higher concentration of the acetate, then the growth of the bacteria will inhibit without inhibiting the central metabolism.
d). This is predicted because as E. coli-M bacteria grows, it starts secreting acetate. This is known as overflow mechanism. The regulatory interactions mediated by the acetyl-phosphate that plays an important role in the inhibiting growth by the acetate.
A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I?
a. Ubiquinone
b. Complex II
c. Complex III
d. Complex IV
Answer:
b. Complex II
Explanation:
The electron transport chain is a sequential series of proteins located in the inner membrane of the mitochondria that act to transfer electrons from different members of the transport chain in a series of redox reactions, which is coupled to the movement of protons (H+) across the membrane. Complex I (also called NADH dehydrogenase or NADH- CoQ reductase) accepts electrons from NADH and passes them to Complex III (also known as coenzyme Q reductase), which also receives electrons from Complex II (succinate coenzyme Q reductase). Ubiquinone (Coenzyme Q) accepts electrons from both complex I and complex II and transfer them to complex III. From complex III electrons pass to complex IV through cytochrome c oxidase and finally to molecular oxygen (O2, the final electron acceptor). In consequence, Complex I and Complex II are linked by different pathways to Complex III, thereby it is expected that Complex II remains unaffected by a mutation in Complex I.
what are the characteristics of normal cells and cancerous cells?
Normal cells stop growing (reproducing) when enough cells are present. For example, if cells are being produced to repair a cut in the skin, new cells are no longer produced when there are enough cells present to fill the hole (when the repair work is done).
In contrast, cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed.

A series of experiments shows that oil content in a diploid grain is influenced by five genes (a through e) with additive alleles. The highest producing strain is 20% oil content; the lowest has close to 0%. A plant of unknown genotype has an oil content of 12%. What is a possible genotype for this plant
Answer:
All the possible genotypes of the plants that have an oil content of 12% include six dominant alleles. Following we are mentioning some of them
AABbCcDdEe, AaBBCcDdEe, AaBbCCDdEe, AaBbCcDDEe, AaBbCcDdEE
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
The possible genotypes involving a combination of six dominant alleles required for the grain to have an oil content of 12% are:
AABbCcDdEe, AaBBCcDdEe, AaBbCCDdEe, AaBbCcDDEe, AaBbCcDdEE
Additive alleles are alleles which result from polygenic traits.
Polygenic traits are traits which are encoded by several genes resulting in more than two alleles contributing to the phenotype.
The phenotype of additive alleles is continuous due to the many different combinations of the alleles of the genes.
From the data provided:
oil content in a diploid grain is influenced by five genes: a, b, c, d, e The highest producing strain is 20% oil content The lowest has close to 0%Since the grain is diploid, grains that are:
h0m0zygous recessive for the five genes, aabbccddee, will have 0% oil content.h0m0zygous dominant for the five genes, AABBCCDDEE, will have 20% oil content.Each dominant gene will contribute 20% / 5 = 4% of oil content.
Since the grains are diploid, each dominant allele will equally contribute 4% / 2 = 2% to the oil content.
Thus:
0 dominant allele → 0% oil content 1 dominant allele → 2% oil content 2 dominant alleles → 4% oil content 3 dominant alleles → 6% oil content 4 dominant alleles → 8% oil content 5 dominant alleles → 10% oil content 6 dominant alleles → 12% oil contentTherefore, a combination of six dominant alleles are required for the grain to have an oil content of 12%.
All the possible genotype involving a combination of six dominant alleles required for the grain to have an oil content of 12% are given below:
AABbCcDdEe, AaBBCcDdEe, AaBbCCDdEe, AaBbCcDDEe, AaBbCcDdEE.

Describe the neural and renal mechanisms that control blood pressure.
Answer:
The autonomic nervous system is the main neural regulator of circulation and blood pressure in the short term and beat by beat and exerts its function through various reflexes that regulate vasomotor tone, heart rate and cardiac output. At the renal level, the renin–angiotensin–aldosterone system is possibly the most important in the maintenance of arterial homeostasis.
Explanation:
Blood pressure is regulated by a series of interrelated autonomic systems and humoral reflexes, which continually adjust the determining elements of the system (heart rate, stroke volume, total peripheral resistance and circulating volume).The effective circulating volume is controlled by a series of reflex systems, which obtain information about the perfusion pressure (baroreceptors in the carotid bulb and aortic arch), plasma osmolarity (hypothalamus) and urinary sodium (distal tubule).The kidney has its own self-regulatory mechanisms. The reduction in renal blood flow is detected at the level of the mesangial cells of the juxtaglomerular apparatus, starting the renin-angiotensin system. The increase in angiotensin II produces on the one hand local vasoconstriction, and on the other hand stimulates the production of aldosterone by the adrenal cortex with the consequent tubular reabsorption of sodium and water.Antidiuretic hormone or vasopressin (released from the hypothalamus by stimulation of arterial baroreceptors and also by stimulation of angiotensin II) also acts at the renal level, which acts as a powerful and water-saving vasoconstrictor in the distal tubule.
Hydrothermal vent ecosystems do not have sunlight available, and hence there are no kinetic energy. Instead, play the role of on which other organisms rely for energy. They compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to sugar molecules. create an additional energy transfer when they these sugars or eat each other. As in other ecosystems, organisms in hydrothermal vent communities also transform into other forms, such as (energy of motion).
Answer:
- Hydrothermal vent ecosystems do not have sunlight available and hence there are no photoautotrophs.
- Instead, chemoautotrophs play the role of producers on which other organisms rely for energy. They oxidize compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to synthesize sugar molecules.
- Consumers create an additional energy transfer when they utilize these sugars or eat each other.
- As in other ecosystem organisms in hydrothermal vent communities also transforms chemical energy into other forms such as kinetic energy (energy of motion).
Explanation:
A hydrothermal vent is a geyser on the seafloor that is generated by underwater volcanoes or tectonic activity through which geothermally heated water erupts. Hydrothermal vent ecosystems contain hydrothermal microorganisms which are able to survive just outside the hottest waters. For example, Methanopyrus kandleri are hyperthermophile prokaryotic microorganisms that live in these ecosystems where they produce methane from reducing CO2. Chemosynthesizers are able to convert carbon molecules (e.g., CO2) and nutrients into organic matter by the oxidation of inorganic compounds such as hydrogen sulfide and/or ferrous ions. Moreover, hydrothermal vent ecosystems have the potential to support high biomass and productivity levels due to the establishment of symbiotic relationships between chemosynthesizers with respiring heterotrophs, which obtain energy from other organisms. Chemosynthesizers are eaten by other organisms (e.g., amphipods and copepods), whereas larger organisms (e.g., snails and crabs) form predator and prey relationships above these primary consumers.
This is the type of ecosystem found on seafloor with geothermally heated water discharges. It lacks sunlight and there are no presence of photoautotrophs.
Organisms present mostly convert chemical energy into other available forms.

As the most junior member of a lab, you are tasked with generating cell lines that accumulate DNA damage to investigate how random mutations affect transformation of cells into cancer cells. You decide to mutate proteins in the p53 pathway. Which three proteins would you mutate
Answer:
In p53 pathways, 3 proteins which are mutate and cause cancer that proteins are:
1.BRCA2
2. p53 in Rb genes binds with deoxyribonucleic acid that stimulates another gene to produce a protein known as p21 that interacts with cdk2. When p21 is combined with cdk2 cell will not pass through to the next stage of cell division. This is Li-Fraumeni syndrome (when p53 causes cancer from parents to offspring)
3.BRCA1
The parent that transmits mutation in one of these genes has a 50% chance of inheriting the mutation. The effects of mutations in BRCA2 and BRCA1 are seen when the person's second copy of the gene is normal.
Give three reasons why you might have a situation in which bacterial colonies were found on the first section of a streak plate, but not on sections two and three.
Hi. You have not shown the sections this question refers to, nor have you provided more information about those sections. This makes it difficult for your question to be answered. However, I will try to help you as best I can.
Generally speaking, we can consider that there was no growth of bacterial colonies in sections 2 and 3, because, for some reason, the bacteria was not inoculated in sections 2 and 3. What could also have happened, is that the bacteria in the sections 2 and 3 were eliminated, but the bacteria from section 1 managed to survive and form colonies.
Another possibility is that after inoculating the bacteria in section 1, you didn't handle the bacteria correctly in the other sections, leaving that bacteria to dry out and die.
Finally, the culture media in sections 2 and 3 could be inappropriate for bacteria to develop and form colonies.
