Explanation:
Humans use special body parts for functions such as breathing and breaking down food. Some living things, such as bacteria, are too small to perform these functions. True false Submit
Answer:
False
Explanation:
Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.
Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.
In addition, bacteria can have different forms of "obtaining food"
Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.
Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.
Because it is ______ , fermentation _______ oxygen.
Answers:
aerobic/requires
anaerobic/requires
aerobic/does not require
anaerobic/does not require
Answer:
anaerobic/does not require
Explanation:
anaerobic occurs in the absence of oxygenIf you could genetically engineer any species of organism, what would it be? Would it be a unicorn? A
dog-cat hybrid? Your own personal pet giant? Choose any species--real or not--that your imagination
desires!
Write a paragraph describing your species, what it looks like, and where it lives. Think of any inherited
traits the species has that might help it survive in its environment. Thinking of these traits now can help
you come up with allele combinations in the next step. Now describe your species in the answer space.
Answer:
the species I would combine would be a trapdoor spider and a eel yeah its a unusual mix but at the same time it would be interesting to see because image a eel having 8 legs and spider fangs and armored skin it would most likely also be twice the size of a normal eel or even might have a mutation but who knows
The alteration of the natural gene is called genetic engineering. Genetic engineering helps to cure various diseases, these diseases are as follows:-
ADA syndromeRNAi interferenceGenetic engineering help to make the new organism with the crossing of the two new species.

Which term refers to the energy an object has due to its position?
Answer:
Potential Energy.
Explanation:
Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.
A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.
Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.
In an energy pyramid, up to 10% of energy is transferred between trophic levels. Suppose the producer level has 50,000 J. Approximately how much energy is available to the next level, the primary consumer, in this energy pyramid?
Answer: 5,000
Explanation:So it is the 10% law, this is an example 10,000 for the first animal, 1,000 for the second and 100 for the third. So for 50,000 it would be 5,000 for the next

DNA is passed on from generation to generation. This is the genetic information and tells the cells what to do and how to operate. So this information does in fact need to be passed on.
Domain is the least inclusive group of all of the categories.
A. True
B. False
Answer:
B. False
Explanation:
Within this hierarchy, living things are organized from the largest, most-inclusive group (domains) down to the smallest, least-inclusive group (called species). Domain: Domains group organisms by fundamental characteristics like cell structure and chemistry. The three domains are Bacteria, Archaea, and Eukarya.
Answer:
B. False
Explanation:
Domain is not the least inclusive group of all of the categories. The three domains are Bacteria, Archaea, and Eukarya.
When purified virulent pneumococci DNA was introduced to avirulent pneumococci, Avery and his colleagues observed _____. Multiple choice question. no death in test animals only growth of avirulent pneumococci, indicating DNA was NOT the agent of transformation death of test mice growth of virulent pneumococci, indicating DNA was the agent of transformation
Answer:
death of test mice, growth of virulent pneumococci, indicating DNA was the agent of transformation
Explanation:
In an experiment conducted by three scientists namely: Oswald Avery, Colin MacLeod and Maclyn McCarty in 1944, it was proven that DNA is the substance that causes transformation in bacteria as opposed to proteins.
In this experiment, Avery and his colleagues combined a dead but virulent strain of Streptococcus pneumoniae & a living but avirulent strain of the same bacterium and inserted into a living rat. They found out that the test specimen (rat) died and observed the growth of the virulent pneumococci.
This suggests that the virulent strain of bacteria has transferred its virulent DNA via transformation into the avirulent strain to kill the rat. Hence, indicating DNA as the agent of transformation.
Which of the following does NOT affect the flow of groundwater through an aquifer ? a. porosity C. gradient b . chemical weatheringd. permeability
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

Explanation:
Si el genoma de una especie contiene un 40% de la base timina, ¿cuál será el porcentaje de guanina del genoma de esta especie? 10% 35% 60% 30% 20%
Respuesta:
El porcentaje de guanina del genoma de esta especie será del 60%.
Explicación:
El genoma de todas las especies está compuesto por ADN (ácido desoxirribonucleico) bicatenario, lo que significa que tiene dos cadenas. Estas cadenas se unirán la una con la otra mediante un componente muy importante en los nucleótidos: las bases nitrogenadas que pueden ser de 4 tipos distintos: timina (T), guanina (G), adenina (A) y citosina (C). Los nucleótidos se aparean siempre de la misma manera para formar pares de bases: citosina con guanina (C-G) y adenina con timina (A-T). De esta manera, podemos inferir que si hay un 40% de base timina en el genoma de una especie, se unirá con un 40% de adenina, y el 60% restante serán pares C-G.
La respuesta correcta es entonces 60%.
What's the differences between species richness management approach and indicator species management way?
Answer:
Both have different function.

What would happen if a populations chose their mates randomly?
A. Allele frequency would be constantly changing at random
B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.
C. Randomly mating allows the most beneficial traits to be passed on because more individuals are going to select for them.
D. Allele frequency would begin to favor the dominant trait.
Answer:
B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.
Explanation:
Like recombination, non-random mating can act as an ancillary process for natural selection to cause evolution to occur. Any departure from random mating upsets the equilibrium distribution of genotypes in a population. This will occur whether mate selection is positive or negative assortative.
