In class we also talked about the metabolism of HDL particles.
zhuklara [117]

Answer:

Explanation:

The basis for the inverse relationship between number of matured HDL in circulation and and cardiovascular disease is that when new HDL entertainment circulation they mature by picking up extra cholesterol until they become mature and high cholesterol level is a major cause of cardiovascular disease and atherosclerosis. The implication of this is that the more the number of matured HDL in circulation, the lower the cholesterol level in the blood thus the lower the risk of cardiovascular disease and atherosclerosis.

Answer:

1. Carbohydrates - It serves several key functions in your body. They provide you with energy for daily tasks and are the primary fuel source for your brain's high energy demands. Fiber is a special type of carb that helps promote good digestive health and may lower your risk of heart disease and diabetes.

2. Protein- You use protein to make enzymes, hormones, and other body chemicals. Your body also uses protein to build and repair tissues. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

3. Lipids - This is essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection

4. Nucleic acids are very important for cell functioning, and therefore for life. There are two types of nucleic acids, DNA and RNA. Together, they keep track of hereditary information in a cell so that the cell can maintain itself, grow, create offspring and perform any specialized functions it's meant to do.

The answer is that a unicellular organism would swell and burst.

In a hypotonic solution <span>the </span>water concentration<span> of the cell's cytoplasm is </span>lower<span> then that of the hypotonic solution. If unicellular organism is exposed to a hypotonic solution, the water from the solution will enter the organism by the process called osmosis. The aim is to balance water concentration on the inside and outside of the organism. But, that water entering the cytoplasm of the cell will make pressure on the cell membrane. If the </span><span>excess water cannot be removed from the organism, it will swell and burst.</span>

What does the biological species concept use as the primary criterion for determining species boundaries?
Marysya12 [62]

Answer:

The correct answer is C) gene flow

Explanation:

The biological species concept defines what is a species. It says that a species is a group of individuals in a population that interbreed with each other. So there should be gene flow between the members of the population to come under species.

Appearance does not define that two individual are of same species because even different species can look same for example Western meadowlarks and eastern meadowlarks looks identical to each other but they do not interbreed so there is no gene flow between them so they are not same species.  

Therefore the primary criteria for determining species boundaries is gene flow.
