Answer:

Proteins

Explanation:

They are found everywhere in the body from muscle, cell membranes, hair, enzymes, and etcetera and are responsible for the phenotype of organisms. Proteins are the ultimate expression of genes in the DNA of organisms. The DNA is transcribed by DNA polymerase into mRNA, then mRNA is translated into protein by ribosomes. This general rule is called the central dogma.

In rats, the allele for long whiskers is dominant to the allele for short whiskers. At another gene locus, a dominant allele pro

PilotLPTM [1.2K]

Answer:

25%

Explanation:

We have 2 independent genes with 2 alleles each: L/l and W/w

W_: whiskers
ww: no whiskers
L_: long whiskers
ll: short wiskers

Individuals with short whiskers will have the genotype WWll or Wwll.

A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:

-The homozygous rat will produce only wl gametes.

-The heterozygous rat will produce the following gametes: WL, Wl, wL, wl.

If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.

The _____ is thin and smooth and is the innermost layer of the heart.

Len [333]

The correct answer is endocardium.

The endocardium is termed as thin and smooth and is the innermost layer of the heart. Endocardium tissues are biologically and embryologically similar to endothelial cells which lines blood vessels.

It provides protection to valves and heart chambers. It is the muscular tissue which is responsible for contraction of the heart.

It also controls myocardial function. It acts as kind of blood-heart barrier and controls ionic composition of extracellular fluid where cardiomyocytes bathe.
