Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell
Explanation:
3a. Scientists think some organisms have eyespots on their bodies to help them lure in prey. Choices True False
Answer:
False
Explanation:
The eye spot instead creates a disguise and used to misdirect predators. The eyespots are a defense mechanism for the organism. Scientists have tested this by painting eye spots on a gake prey and a fish was used a s the predator. The predator was discovered to have attacked the fake eyespots more often as it thought it was the prey's head.
Eyespots on a prey can also make the predator to think that it is facing a larger animal. An example is the butterfly which have large false eyes on its wings.

Mistakes in making copies of a cell's chromosomes can occur as the cell is dividing. Such mistakes can affect a single gene, or a portion of a chromosome. Which term describes this process?
Answer:
Mutation
Explanation:
A mutation is any change in the nucleotide sequence of the genome of a particular organism. Mutations may be caused by errors during DNA replication or by exposure to environmental mutagenic factors (e.g., ultraviolet radiation, chemical agents, etc). Mutations can be deleterious, neutral or beneficial depending on the environment. When a beneficial mutation occurs in the germline, it may potentially be inherited and subsequently increase its frequency in the population.
Examine the genotype for an individual who is AaBbCcDd. Predict the outcomes of meiosis and the potential gamete combinations
that could form from this individual. Select ALL that apply.
A)
50% of the gametes will be AaBbCcDd.
B)
1/16 of the gametes produced will be ABcd.
The individual could make gametes that contain ABCD.
D)
The individual could make gametes abcd half of the time.
E)
Only dominant traits will be present in the gametes from a heterozygous
individual
Answer: B,C
Explanation:
I did just did the USA test prep
The outcomes of meiosis and the potential gamete combinations that could form from the genotype for an individual who is AaBbCcDd:
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.
A a simple method to calculate the number of gametes:
Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.n = 4
Then, total number of gametes will be = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16Thus 16 in this condition
The 16 types of gametes are formed by this individual by permutation and combination are:
ABCD, AbCD, ABcD, ABCd,
ABcd, AbcD, ABCd, Abcd,
aBCD, aBCd, aBcd, aBcD,
abCD, abCd, abcd, abcD.
Thus, the correct answer is -
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.Learn more about permutation and combination:

why adaptation is important for living beings
Answer:
Adaption is needed for a living thing to strive in a system, its how they survive.
Explanation:
Adaptation is needed to survive. This includes climate, predators around it etc. For example polar bears. Polar bears adapt to their environment by growing thick coats of fur. These coats keep the bears warm.Without it they would die.

Answer:
Correct answer is C. The cell will not be replaced when it is damaged
Mammalian erythrocyte lacks nucleus. Why? Give reason.
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.

Answer:
The punnet squares are in the pic above. Either of them could be correct because the mother may have 2 dominant traits (FF) , or one of them could be recessive (Ff).
Are genetic mutations avoidable? Explain.
Answer:
Mutations happen in our cells all the time. It's actually how all humans grow and change. The vast majority of mutations are harmless. Thus, they aren't avoidable.
Mutations occur in our cells all the time. It's how all humans grow and transform. The vast bulk of mutations is harmless. Therefore, they aren't avoidable.
What are Genetic Mutations?
The permanent transmissible difference in the genetic material. An individual exhibiting such a transformation. A point mutation is a mutation resulting from a modification in a single bottom pair in the DNA molecule.
Any alteration in a nucleotide succession of DNA is called a mutation. Chromosomal, dependent, and gene mutations are some of the illustrations of different kinds of genetic mutations.
So, Therefore, They aren't avoidable.

Answer:
There's a difference.
Explanation:
Anaphase I involves the separating of chromosomes from the sister chromatids and it all occurs in a diploid cell.
Anaphase II involves the split of the sister chromatids into single chromatids and it all occurs in a haploid cell.

Children inherit half of their genes from parents. Explain Why?
Answer:
This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.
Answer:
yes
Explanation:
The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.
