Answer:
Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their mother and half from their father.
Explanation:
(Sorry, I'm not sure)
The false statement is: All deuterostomes exhibit radial symmetry in their bodies.
For example, phylum Chordata contains animals that don’t have radial symmetry.
Deuterostomes share characteristics such as coelom that forms from folds of archenteron, radial, indeterminate cleavage, anus formed from blastopore.
The major distinctions between these two groups of animals (Bilateria) deuterostomes and protostomes are in their embryonic development. Another difference is that most Protostomes have schizocoelous development (cells fill in the interior of the gastrula and that is the way the mesoderm is formed) On the other side, in Deuterostomes, the mesoderm forms through invagination of the endoderm (enterocoelic pouching).
The main dietary factor associated with elevated blood cholesterol is saturated fat.
<h3>
What about saturated fat?</h3>
- Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke).
- Cholesterol that is circulated in the blood.
- The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat.
- Even if they include fat, foods derived from plants never contain cholesterol.
- Only foods from animals do. Low density lipoproteins are able to transport cholesterol.
- Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood.
- Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.
- When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.

Answer:
<h2>Genotypes of parents are Rr and rr.</h2><h2 />
Explanation:
A homozygous fox would have either two dominant alleles (RR) or two recessive alleles (rr).
A heterozygous fox would have a mix of both one dominant allele and one recessive allele (Rr).
However, a heterozygous fox can only be red, as the (Rr) combination will make it so that the dominant red coat trait will rule over the recessive allele.
(a). as given that f 1 generation are 4 red and 3 white , so RED coat can not be homozygous dominant , So red coat will be Rr (heterozygous dominant).
(b). silver coat is recessive homozygous , rr
(c). genotypes of offspring Rr, Rr, rr, rr.
(d) yes
(e) yes
