Answer:
Genes segregate equally into gametes
Explanation:
Gregor Mendel, due to his contribution to genetics, is referred to as the FATHER OF GENETICS. Among his contribution is the principles that governs inheritance in organisms. One of those principles is LAW OF SEGREGATION.
LAW OF SEGREGATION states that the alleles of a particular gene will separate into gametes in an equal manner. For example, in a gene Aa, each gamete produced by the organism with this gene will contain either allele A or allele a in equal proportion.

What is Chargaff's Rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

When did whale ancestors begin living full time in the water?
A) before they nursed under water
B) after they began eating a carnivorous diet
C) before they evolved gills
D) after they lost their hind legs
Answer:
40 million years ago
The earliest whales that we think were fully aquatic, that is, they never left the water, are found around 40 million years ago, during the middle Eocene. That means that the transition from terrestrial animals to fully aquatic animals took about 12 million years.
Explanation:
Answer:
After they nursed under water

7. In a cross with a homo zygous, grey, female moth and a homo zygous, black, male moth, all of the progeny are grey. In a cross with a homo zygous, black, female moth and a homo zygous, grey, male moth, all of the progeny are black. What is the best explanation for this? (2 words)
Answer:
Due to dominant trait.
Explanation:
The best explanation for this result is that grey colour is dominant trait due to which all of the progeny appears grey while in the second example, black colour is dominant trait which appears in the all the offspring of moth. In the offspring, only that trait becomes visible which is dominant while the trait which does not appear is known as recessive trait so that's the reason due to which grey in the first and black colour in the second becomes visible.
The genus Cnemidophorus is a large group of whiptail lizards that are found in both North and South America. These lizards undergo a process in which their unfertilized eggs can develop into new individuals. This process is called
Answer: The question is not complete, options are not given but here are the options from another websites.
a. sexual reproduction.
b. binary fission.
c. parthenogenesis.
d. budding.
The correct option is C.
Parthenogenesis.
Explanation:
lizards undergo a process in which their unfertilized eggs can develop into new individuals and the process is called parthenogenesis because parthenogenesis is a reproductive strategy that involves the reproduction of new organisms without undergoing fertilization or the production of new organisms from unfertilized eggs and these can be as a result of the lizard not able to undergo sexual reproduction which can be as a result of environmental factors. This process does not involve sexual reproduction.
Which is a disadvantage of asexual reproduction?
Answer: The major disadvantages of asexual reproduction are: Lack of diversity. Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.

Do you think the genetic disorders you identified in part A or B would appear in a person’s DNA fingerprinting profile? Explain your reasoning.
Answer:
Yes, I think genetic disorders would appear in a person's DNA fingerprint profile. It would appear because everyone has a variation in their DNA and genetic disorders show up in DNA, so it would appear in a person's DNA fingerprint profile.
Explanation:
John is completing an internship in biology at the Clearwater Marine Aquarium. While interning there, he monitors an outdoor phytoplankton exhibit to observe how populations of phytoplankton change when exposed to light. It is observed that each year the phytoplankton population within the exhibit increases when it was exposed to high amounts of sunlight. A new apartment complex that overlooks the aquarium is being built. The phytoplankton that were receiving 8-12 hours of sunlight each day will now have between 2-5 hours of sunlight. How will the phytoplankton be affected by the new apartment building?

is the diffusion of water molecules across a
semipermeable membrane and down a concentration gradient.
Answer:
Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. ... The semipermeable membrane limits the diffusion of solutes in the water.

What is one of the roles of the enzyme, DNA Polymerase, during DNA replication?
Answer
F
It degenerates (breaks down) the old DNA strand once the new strand is made
G
It uses a strand of DNA to build a new strand of RNA
H It joins nucleotides to synthesize a complementary strand of DNA
J
It unzips the two strands in a molecule of DNA to begin replication
Answer:
H
Explanation:
Couldn't find my notes for this, but research says H- it builds a complimentary DNA strand
In a strand of DNA, if the percentage of thymine is 30%, what would the percentage of cytosine in the same DNA strand be?
Answer: 20%
Explanation:
I haven't learned this exactly yet, but if there is 30% of thymine, then there has to be 30% of adenine because they match. That would leave 40% for other Guanine and Cytosine, and since they also match that means that it is exactly half, meaning that there is 20% Guanine and 20% Cytosine.
Which statement is NOT true about fluids?
A. all can flow
B. liquid and gases are included
C. some take the shape of their container
D.particles move easily past each other
Answer:
option D is correct
Explanation:
The statement which is not true about fluids is particles move easily past each other.
What do you mean by Fluids?Fluids may be defined as any liquid or gas or generally any material that experiences a continuous change in shape when subjected to any object.
The properties of fluids indicate that all fluids can flow depending upon their densities. Some take the shape of their container due to fluidity. Fluids comprise liquid and gases.
Therefore, the statement which is not true about fluids is particles move easily past each other.

A. An enzyme functions to decrease the rate of a chemical reaction.
B. Enzymes are proteins that function as catalysts in nonliving things.
C. Each enzyme can catalyze many different biochemical reactions.
D. Enzymes and substrates fit together like a lock and key.
Answer:
d
Explanation:
a is wrong as enzymes function is to increase the rate of a chemical reaction.
b is wrong as enzymes are proteins that function as catalysts in living things
c is wrong as each enzyme can catalyse a single reaction as they all have an unique pattern

A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.
C. Yes, because the number of atoms of each element is the same on both sides of the equation.
Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

John and Sarah had a child born with cystic fibrosis, a genetic disease. Both John and Sarah were normal, showing no signs of this disorder. How is it possible for them to have a child with this disease?
a. Cystic fibrosis must be a dominant trait disorder hidden in both parents' genotype, but not showing in the phenotype, that could be passed on to offspring.
b.Cystic fibrosis must be a recessive trait disorder hidden in both parents’ genotype, but not showing in the phenotype, that could be passed on to offspring.
c. Cystic fibrosis must be a dominant trait disorder hidden in one parents’ genotype, but not showing in the phenotype, that could be passed on to offspring.
d.Cystic fibrosis must be a recessive trait disorder hidden in one parents’ genotype, but not showing in the phenotype, that could be passed on to offspring
