which are the target organs of insulin and how do they respond to the home?

Answers

Answer:

Action of insulin

Insulin plays an important physiologic role, especially in the liver, muscle, and adipose cells, in homeostasis of blood glucose concentration (4). For this reason, the liver, muscle, and fat have been regarded as major target tissues for insulin.

The primary targets for insulin are liver, skeletal muscle, and fat. Insulin has multiple actions in each of these tissues, the net result of which is fuel storage (glycogen or fat). Glucose enters the circulation either from the diet or from synthesis in the liver.

write a debate conversation on the following topic

Answers

Answer:

Person one

We must take measures to reduce our carbon footprint! There are so many options we can take. We can start to produce, and invest in, more solar and wind powered solutions to produce our electricity. We can also cut down on our reliance on gas powered vehicles to move us everywhere. If we were to invest more in electric powered vehicles, start to use more bicycles, or even carpool and take the bus more we could greatly reduce our carbon footprint.

Person two

You talk about all of these “amazing ways” we can reduce our carbon footprint, but you haven’t even considered the inconveniences and the cost of these ways. Solar and wind powered options don’t produce nearly as much power as a coal plant! Not to mention the cost of them. Gas powered vehicles have been around for 100 years, and electric cars haven’t been around for nearly as long and they are very expensive! Also, in the winter, not everyone wants to be freezing cold on a bike, and not everyone has a friend or coworker they can carpool with.

Person one

First of all, I know that these methods would be expensive at first, but if we were to actually take them seriously then they could become inexpensive, and reduce our carbon footprint. The electric car may be newer, but it reduces the carbon output greatly. Investing in these is key in creating a greener future for future generations, and if we don’t reduce our carbon output soon there might not be a planet left for our future generations! All of these methods might seem expensive at first, but in the long run cost will go down, and the high cost at first will be worth it if it means reducing our carbon footprint. Therefore I believe it is necessary that we reduce our carbon footprints, and these are just a few of the ways how.

Person two

You have no way of knowing that the methods would become cheaper over time. They may only grow in cost, while our coal and oil prices have been steady and low for a long, long time. Investing in these ideas would mean taking away money that could be funding more important things such as space travel, or deep sea exploration. Why do you think that there may not be a planet left for future generations? Just because we aren’t reducing our carbon output doesn’t mean we won’t have a planet to live on. I believe that we should not focus on reducing our carbon output because we have much more effective methods of producing electricity and traveling than solar and wind powered devices.

How does interphase prepare cells for mitosis
rest prior to cell division
growth of cell and replication of DNA
dissolution of nucleus and cell membrane
division of cytoplasm

Answers

Answer:

In interphase there are three phases in which the cell multiplies its contents. DNA is replicated and cell organelles are doubled and all necessary biomolecules are formed. In this way cell gets prepared for mitosis.

Interphase is the time of the cycle when the cell grows and replicates DNA. Therefore, option  "A" is correct.

What is the cell cycle?

The cell cycle consists of a series of events in sequence by which the cell duplicates its genome and eventually divides into two daughter cells. It is divided into two phases i.e., M phase and interphase. Interphase is the preparatory phase for the cell to undergo cell division whereas the M phase is the mitosis phase in which the cell divides.

The interphase phase is further divided into four phases: G1- the period between the end of the M phase and the start of DNA replication.S- also known as the synthesis phase in which the synthesis of DNA occurs.G2-division of the cell.

Therefore, the cell cycle is an important event.

Explanation:

Answer:

The correct answer is - Concave shape of Wave Rock.

The concave shape of Wave Rock is a nice physical evidence of deposition in the Earth's evolution. It is a land structure dated to 2.7 billion years old, and it is the basis around which the Australian continent formed. The Wave Rock structure is created by weathering of the surrounding area, and this is exactly what proves the deposition part, because Wave Rock was bellow the ground, and that was due to the deposition of the material around it over time, but since it is made out of much tougher material from its surroundings, the weathering lowered the surrounding terrain, while the bedrock remained to witness for the past.
