how do mitosis and meiosis play a role in cat breeding? Explain.
Answer:
mitosis is a process of body cell formation, while meiosis is a process of reproductive cell formation. i hope i helped (instagram itzactuallytif)
Answer:
: Mitosis and meiosis both are the types of cell division which occurs in the body of living organisms. Mitosis is responsible for growth and development in the body of cat because in mitosis, one cell is divided into two daughter cells and again these two cells divided into four and so on which increases size of organisms, while meiosis is responsible for the production of sex cells in cat which enables them to continue its breeding and produce fertile offspring.

The ability to remove bacteria from the cell.
B The ability to use energy to make proteins used in the cell.
The ability to modify, sort and package proteins and lipids for storage or
C
transport out of the cell.
The ability to allow needed materials to enter and wastes to exit as well as the ability to block
unneeded materials from entering the cell.
D
Answer:
The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell.
Explanation:
A selectively permeable cell membrane only allows some things to go through it, therefore this answer choice is the correct one because it is explaining how it is selectively permeable.

What is the function of the cell membrane in a cell?
Answer: The plasma membrane or cell membrane provides protection for a cell
Explanation: it also provides. Functions
The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.
What is cell membrane?The cell membrane has been defined as the structure found in the cell and the function of cell membrane is to provide protection to the cell. The cell contain several cell organelles and these are ribosomes, golgi appratus, nucleus, and the cell organelles have different functions.
When movement of molecules is takes place then it is called active transport. Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that substance are moving their own concentration gradients.
Therefore, The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.

Why are sex-linked traits more common in males than in females?
a.All alleles on the X chromosome are dominant.
b.All alleles on the Y chromosome are recessive.
c.A recessive allele on the X chromosome will always produce the trait in a male.
d.Any allele on the Y chromosome will be codominant with the matching allele on the X chromosome
Answer:A
Explanation:
Sex-linked traits are more common in males than in females because all alleles on the X chromosome are dominant.
What do you mean by sex-linked traits?Sex linked describes the sex-specific patterns of inheritance and presentation when a gene mutation is present on a sex chromosome rather than a non-sex chromosome. In humans, these are termed X-linked recessive, X-linked dominant and Y-linked.
And in humans this is the X or the Y chromosomes. And so some of the more familiar sex-linked traits are hemophilia, red-green color blindness, congenital night blindness.
Sex-linked traits are characteristics that are determined by genes located on the sex chromosomes. Inheritance patterns for these traits can differ for males and females, since the X and Y chromosomes differ.

Which processes provides evidence for the claim that energy is transferred
during cellular respiration? Select all correct answers.
A. The electron transport chain
B. Carbon dioxide is released
C. hydrogen ions move down the concentration gradient across the inner membrane
D. transfer of electron carriers such as NADHand FADH2
E. water is formed
Answer:
B. Carbon dioxide is released
E. water is formed
Explanation:
Cellular respiration is defined as the metabolic processes in which chemical energy is converted into ATP and the waste product is released by the cells.
The processes that provide evidence for the claim that energy is transferred during cellular respiration are Carbon dioxide is released and water is formed. During cellular respiration, oxygen and glucose are converted into carbon dioxide and water, and the energy is transferred to ATP.
Hence, the correct answers are "B and E".

Which of the processes offers the GREATEST evolutionary advantage of sexual versus asexual reproduction?
А
meiosis
B В
mitosis
С
budding
D
binary fission
Answer:a
Explanation:
The process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS.
Meiosis is a type of cell division that is used by organisms of sexual reproduction to produce haploid (n) gamete cells.Meiosis produces new genetic variation in offspring due to:
the random separation of alleles in gametes when chromosomes separate crossing-over or recombination which is the interchange of genetic material between non-sister chromatidsgametes randomly fuse to produce a diploid (2n) organismIn conclusion, the process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS because it is capable of introducing new alleles and increasing genetic variation in a population.
