Cholesterol is synthesized by all animal cells and is an essential structural component of animal cell membranes. Cholesterol is the most common steroid and is mainly synthesized in the liver. Cholesterol also serves as a precursor for several important biological compounds including all, EXCEPT: A) insulin B) vitamin D C) bile salts D) testosterone

Answers

Answer 1

the answer is insulin. because the precursor for insulin is called pro insulin

Answer 2

Cholesterol does not serve as the precursor for insulin. So the correct option is A.

What is cholesterol?

Cholesterol is a wax-like substance. Cholesterol is considered to be bad among the general public but it is not inherently “bad.” Our body needs for building cells and making vitamins and several other hormones. Cholesterol levels, in excess, can pose a problem.

Cholesterol can come from two sources. These are synthesized by the liver and from foods from animals. The liver produces all the required cholesterol but the remainder is obtained from foods. For example, meat, poultry, and dairy products of them contain dietary cholesterol.

These are the same foods that are also high in saturated fats and trans fats. These fats cause the liver to make more cholesterol than required or more than it normally does. This added production of cholesterol, for some people, means they go from a normal level of cholesterol level to unhealthy level of cholesterol.

Therefore the correct option is A.

Both natural processes and human activity are causing some of Earth's permanent bodies of ice to melt. If enough of this ice melts, it will add warm freshwater to the northern Atlantic Ocean, where deep water currents start. What effect is this likely to have

Answers

Answer:

EFFECTS - : Melting glaciers and icebergs release fresh water and reduce the salinity of the surrounding sea. The seawater also becomes less dense, changing patterns of ocean currents.

Explanation -

MELTING OF ICE AND ADDING WARM FRESH WATER TO NORTH ATLANTIC OCEAN -:  As part of the thermohaline circulation (also called the Global Ocean Conveyor), seawater flows through the Atlantic, the normal pattern by which seawater passes to the oceans of the world. Due to variations in water density caused by differences in temperature and salinity, the water in the Global Ocean Conveyor circulates. Colder water is denser than colder water, while salter water is denser than fresh water or less salty water.

Water heated at the Equator flows north to cold high latitudes at the surface of the ocean, where it becomes colder. When it cools, the deep ocean becomes denser and sinks. To take its place, more warm surface water flows in, cools, sinks, and the pattern continues. But this trend may be modified by melting Arctic sea ice.

The influx of freshwater from the melting ice makes seawater less salty and thus less thick at high latitudes as the Planet begins to warm and Arctic sea ice melts. In reality, data shows that over the past few decades, the North Atlantic has already become fresher.

Answer:

Salinity changes in water

Explanation:

From the scenario described the Engineers have met one of the main criteria which is for it to be durable. A design needs to be made with a material that is available, durable, and cheap in order for it to be as efficient as possible while also selling and being profitable. By finding the material polycarbonate they have made sure that the design will be durable as well as cost-efficient since the material is "not too costly". Now if they are able to acquire the material in large quantities then they would have met the availability criteria as well.

How do active and passive transport help a cell respond to changes in the environment?

Answers

- both transport things across the cell membrane
- help the membrane maintain homeostasis

Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.

What is Cellular transport?

Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.

The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

Claim Evidence Reasoning. Evaluate the following claim: Meiosis is different than Mitosis.

Answers

Answer/Explanation:

Yes, although they have similarities, meiosis and mitosis are different.

Similarities

Meiosis and mitosis are both types of cell division that results in the production of daughter cells.

They go through similar processes of prophase, metaphase, anaphase, and telophase.

Differences

However, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.

Meiosis produces four genetically different haploid cells from a diploid parent cell.

There are two rounds of cell division in meiosis, and only one round in mitosis.

Gametes produced by an organism contain a combination of genes from that organism. In every gamete, this combination is

A. the same because it is created from the same DNA

B. the same because chromosomes are copied prior lo melosis

C. different due to DNA replication prior to mitosis

D. different due to independent assortment during meiosis​

Answers

Answer:

D). different due to independent assortment during meiosis​

Explanation:

Gametes that an organism produces accommodates a blend of genes of that organism and in each gamete, this blend or combination is 'distinct and that is due to independent assortment during meiosis.' It implies that the chromosomes pass randomly for isolation of poles during the division of cells at the time of the process of meiosis and this independent segregation causes each gamete to contain a unique combination of genetic code. Thus, option D is the correct answer.
