Why are soluble fi bers identifi ed as prebiotics?

Even though human proteins are susnthesized from only 20 different amino acids, there are thousands of different proteins found in human cells

I have read alot about L-carnitine supplements and their benefits. The only thing I do not understand is that when you ingest the supplement, is the peptide not just broken down into amino acids?

I know what carnitine can do for the body when produced internally, but in the end you are just absorbing previous components of the peptide when taking a supplement. So how can claims be made about it, when in the end you just get some extra amino acids that your body could take and make anything out of?

There are two reasons why light is important for this phase. What does it do for the PS II phase?

Certain dominant alleles are so important for normal development that the mutant recessive alleles, when homozygous, lead to the death of the organism. However, such recessive alleles can be perpetuated as heterozygotes (Ll), which in many cases are not phenotypically different from homozygous (LL) normals. Consider the matting of two such heterozygotes, Ll x Ll. among their surviving progeny, what is the probability that an individual will be heterozygous?

in mice at one gene locus the dominant allele (B) produces a dark brown pigment; and recessive allele (b) produces a light brown or tan pigment. An independently assorting gene locus has dominant allele (C) the permits the production of all pigments. It's recessive allele (c) makes it impossible to produce any pigment at all. the pigments less condition is called "albino"

a) A homozygous bbcc albino mouse mates with a homozygous BBCC brown mouse. Assuming independent assortment, in what rations would the phenotypes and genotypes be expected in the F1 and f2 generations?

B) If an f1 mouse from part (a) above was backcrossed to its albino parent, what phenotypic and genotypic ratios would be expected?

1. In humans, having unattached earlobes is dominant. If 36% of the population have attached earlobes, then what is the frequency of the population that has the dominant phenotype.

2.P^2+2pq+q^2=1P2+2pq+q2=1 and p + q = 1. In humans, having unattached earlobes is dominant. If 36% of the population have attached earlobes, then what is the frequency of the population that is homozygous dominant.
