"Blending" genes is associated with:
O Complete Dominance
O Blood Typing
O Incomplete Dominance
O Codominance

Answers

Answer:

a

Explanation:

The "blending" of genes is associated with incomplete dominance.

Incomplete dominance occurs when neither of the two alleles in a gene pair is completely dominant over the other.

Instead, the phenotype of the heterozygous individual is an intermediate blend or mixture of the phenotypes associated with each allele. In other words, the traits from both alleles are expressed in a blended or intermediate manner.

For example, in a cross between a red-flowered plant (RR) and a white-flowered plant (WW), if incomplete dominance is present, the resulting offspring (RW) may have pink-colored flowers, which represent a blend of the red and white traits.

Thus, the answer is incomplete dominance.

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?

Answers

As to the digestive tract, the function of the lipases would take place in the small intestine.

Lipase is an enzyme that helps us to metabolize fat. It does this through hydrolysis. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.

Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.

Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.

https://brainly.com/question/2847647?referrer=searchResults

In the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.

Fat digestion occurs efficiently and almost completely in the small intestine by pancreatic secretion of lipases.

Pancreatic lipase acts on triacylglycerides to give free fatty acids and monoacylglycerides.

First, they are absorbed by the epithelial cells of the intestinal wall called enterocytes, creating complex particles called chylomicrons, loaded with triglycerides.

Fatty acids are re-esterified within the enterocyte and enter circulation through the lymphatic pathway as chylomicrons.

Chylomicrons bind to lymph, which carries them to the bloodstream, this indicates the great importance of lymph in the process of assimilation of dietary fats.

Therefore, we can conclude that in the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.

Suppose you remove the rabbits, grasshoppers, birds, and mice ( the herbivores) from a food web that also includes grass, mushrooms, lizards, and hawks. Which organisms would be affected and how?

Answers

If you remove the herbivores from a food web that also includes grass, mushrooms, lizards, and hawks, the organisms that would be affect are lizards, and hawks.

A food web shows all the possible feeding relationships in an ecosystem. Recall that there is an interconnection between organisms which involves exchange of matter and energy through feeding relationships.

In the food web, the grass is the producer, the herbivores are the primary consumers and the carnivores are the secondary consumers. These secondary consumers eat the primary consumers.

Lizards eat grasshoppers and hawks eat birds. When these are removed from the food web, the Lizard and Hawk are most affected because they will starve owing to lack of prey.

Uncontrolled cell growth is often associated with mutations in genes encoding proteins that promote cell division. These regulatory proteins are known as mitogens or growth factors.

The consequence of a mutation that leads to rapid and uncontrolled cell growth is that the organism would begin to develop cancerous masses.

Cancer is uncontrolled cell growth, which is caused by mutations in genes involved in the control of cell division.
