Answer:

The correct answer is - h(omo)zygous recessive

Explanation:

When a cross between the organism with dominant phenotype, that can be heterozygous genotype or h(omo)zygous genotype, with a organism of h(omo)zygous recessive takes place, the cross known as test cross.

Test cross always exhibit an individual with the dominant phenotype. he aim of test cross is to find if the dominant individual is h(omo)zygous or heterozygous.

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.

If a bullet were to penetrate a lung, which three anterior thoracic body cavities would it enter, and which layer of the serous
Stella [2.4K]

Answer:

First of all is ventral: cavity that makes up the thoracic and abdominopelvic cavity ventral: cavity that makes up the thoracic and abdominopelvic cavity

Secondly it is thoracic: chest cavity

And thirdly it is pleural cavities: which consist of ths lung cavity

That is it will encounter tbe parietal layer of the serous membrane first :lines cavity

Explanation:

The organs in the body are safely guarded by the membrane, cavities and sheaths(which has different compartment). They act to protect the organs in the body like lungs.

A person who was shot with a gun, the bullet must pass the body cavities when moving to the lungs. It must first pass through the 3 cavities before it arrives at the lungs that is the ventral cavity, thoracic cavity and the pleural cavity. The serous membrane is usually found within the walls of the thoracic cavity.
