Katyanochek1 [597]3 years ago
5 0

Answer:

C- Hepatic portal vein

Explanation:

The hepatic portal vein is a vessel that moves blood from the spleen and gastrointestinal tract to the liver.

The portal vein supplies approximately 75 percent of blood flow to the liver. It's not a true vein, which means it doesn't drain into the heart. Instead, it brings nutrient-rich blood to the liver from the gastrointestinal tract and spleen. Then the liver can process the nutrients from the blood and filter out any toxic substances it contains before the blood goes back into general circulation.

In goats, the gene for coat color is on an autosome and light brown color is dominant to black. A light brown male is mated to a
Llana [10]

Autosomal dominant condition occurs when alleles of genes present on chromosomes in the autosomes (somatic) mask the effect of the other allele.

They can produce a light brown kid and the chances of producing this is 50%.

  • Light brown color is dominant to black. A light brown male is mated to a black female, producing a black kid.
  • For the two to produce a black kid which is in the recessive condition, the male has to be heterozygous for the condition (Bb).

Let light brown be (BB or Bb)   and black be (bb)

Parents :                   B b     x      b b

Offspring genotype:      Bb      bb

Ratio:                               1    :     1  (50%)

How is a trait such as fur color is passed down from parents to offspring?
Dvinal [7]
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. Hope this helped :)

At prehistoric clamshell is buried bye sediment on the seafloor overtime the sediment turns to rock and the clamshell dissolves
Wittaler [7]

Answer:

Mold fossil.

Explanation:

The clamshell shaped  cavity is a mold fossil owing to the fact that the clamshell died, its body deteriorated but while it is deteriorating it is being covered by sediment. As a result when the clamshell completely disappears it will leave an impression on the sediment, in other words, it is a mold of the prehistoric clamshell.
