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.

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.

Gametes contain ______ copy/copies of each gene.
Two
Four
One
Thee
Answer:
one
There may be many possible alleles for any gene, but a diploid cell or animal contains only two alleles of each gene or two copies of a single allele; a haploid gamete contains one copy of each gene, so only one allele.

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.

Which is the role of restriction enzymes?
to isolate the selected gene
to cut DNA into fragments of different lengths
to move and separate the strands of DNA
to join the sticky ends of DNA fragments
Answer:
to cut DNA into fragments of different lengths
Explanation:
A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.
More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. In live bacteria, restriction enzymes function to defend the cell against invading viral bacteriophages. Restrictions sites in the viral genome (a "happy accident" of nature, as far as the bacteria are concerned, since they don't appear to have any specific function in the virus) are cleaved by the bacterium's restriction enzymes, fragmenting and destroying the DNA of invading bacteriophages before it can incorporate into the host's genome and take over the cell.
A bacterium is immune to its own restriction enzymes, even if it has the target sequences ordinarily targeted by them. This is because the bacterial restriction sites are highly methylated, making them unrecognizable to the restriction enzyme.
Isn't evolution fantastic?
The correct answer is option C i.e. to cut DNA into fragments of different lengths.
what is restriction enzyme?A restriction enzyme is a bacterial protein that cleaves DNA sequences at sequence-specific places, resulting in DNA fragments with known sequences on both ends.
Certain laboratory processes, such as recombinant DNA technology and genetic engineering, require the use of restriction enzymes.
There are four different types of restriction enzymes: type I, II, III, and IV, which differ principally in structure, cleavage site, specificity, and cofactors.
Both restriction and methylase functions are carried out by a single big enzyme complex in Types I and III enzymes.
The restriction enzyme is independent of its methylase in the Type II system.
Several thousand type II restriction enzymes have been identified from a variety of bacterial species.
These enzymes recognize a few hundred distinct sequences, generally four to eight bases in length.
Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.
Type IV restriction enzymes cleave only methylated DNA and show weak sequence specificity.
hence, the correct answer is option B.

How far does an animal have to travel to obtain the abiotic factor water?
Answer:
Three fourth of the total earth is covered with water, 97 percent of which is there in sea's as saline water, the other 2 percent is there in the form of glaciers and the left out 1 percent is there as ground water.
Water is presence is abundance but it depends upon the geographical location where the animal is looking for water. There will be scarcity of water in the deserts because there is less rainfall over there, so it depends on the geographical location.
