Assume that you are a marine biologist. Choose a marine phyletic group and write a report on its diversity and the adaptations
Maslowich

Answer:

These organisms should be adapted to live in this enviroment, i.e., they need to have adaptations to breathe, to swim (fins), streamlined bodies to move through the water, to eat the food found in the region, etc. Moreover, in this environment, the diversity tends to be high because marine regions are often characterized by their richness.

the salivary glands, stomach, and pancreas secrete ____________ enzymes to break down triglycerides into monoglycerides, fatty a
likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

  • It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

  • The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

  • It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

  • They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

The hydrolysis of atp on the na+/ k+ pump results in
Shalnov [3]
I believe it results to a conformation change that moves the Na+ binding site to the inside of the cell. ATP hydrolysis involves the release of chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate.For example in muscles. The process of moving sodium and potassium ions across the cell membrane is an active transport process involving the hydrolysis of ATP to provide the necessary energy. It involves an enzyme referred to as Na+/K+ ATPase.

"a man with genotype bb and a woman wth genotype BB have four children. how many of the children are likely to have blue eyes"
Sonja [21]

Answer:

No children will have blue eyes all of them carry brown eyes only.

Explanation:

The cross between a male with bb genotype and female with BB genotype will be as follows :

The gametes will be formed

male: b and b

female: B and B

By Punnett square:

        B          B

b       Bb        Bb

b       Bb        Bb

As all the offspring will have a heterozygous condition with dominant B (Brown) and recessive b( blue) so there are no offspring will be with the phenotype of the blue eyes.
