In general, how does biodiversity vary across the biosphere?

Answers

Answer 1
Answer:

Latitude and longitude spatial variation of temperature affects climate and then the distribution of biodiversity.

What is Biodiversity?

Biodiversity is defined as the diversity of all living things such as different plants, animals and microorganisms, the genetic information contained in them and the ecosystems they form which are generally explored at three levels - genetic diversity, species diversity and ecosystem diversity.

Biodiversity is essential to the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we could not have the healthy ecosystems we rely on in the air we breathe and the food we eat and the people who value nature. This is affected by latitude and longitude variation of temperature.

Thus, Latitude and longitude spatial variation of temperature affects climate and then the distribution of biodiversity.

Answer 2
Answer: Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.

Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.

A population of 1,000 birds exists on a small Pacific island. Some of the birds are yellow, a characteristic determined by a recessive allele. The others are green, a characteristic determined by a dominant allele. A hurricane on the island kills most of the birds from this population. Only 10 remain, and those birds all have yellow feathers. Which of the following statements is true?

What is the name of the valve that is located between the right ventricle and right atrium? A) bicuspid B) tricuspid C) aortic D) pulmonary

Answers

B. Tricuspid Valve is located

Final answer:

The valve between the right atrium and right ventricle is the tricuspid valve, which helps prevent backflow of blood.

Therefore , the correct answer is (b).

Explanation:

The valve that is located between the right atrium and the right ventricle of the heart is referred to as the tricuspid valve. This valve's job is to prevent the backflow of blood into the right atrium when the right ventricle contracts. The tricuspid valve has three flaps or cusps, which is where its name comes from. The other options listed, such as the bicuspid, aortic and pulmonary valves, are located in other parts of the heart.Therefore , the correct answer is (b).

"RNA retroviruses use" A. use restriction enzymes to replicate and transcribe their genomes. B. viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it. C. host DNA polymerase to replicate their genome and host RNA polymerase to transcribe it. D. viral RNA-dependent RNA polymerase to replicate their genomes and transcribe it.

Answers

Answer:

B. viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it.

Explanation:

RNA retrovirus when enters into its host cell it first use its reverse transcriptase enzyme and converts its RNA genome into the DNA so that viral DNA can be incorporated into the host cell and it can be replicated with the host cell.

One of the famous example of RNA retrovirus is HIV which infect CD4 cells and converts its RNA into cDNA with the help of reverse transcriptase enzyme and then this DNA enters the nucleus of the cell and incorporates into the host genome. Then it use host machinery to be transcribed. So the correct answer is B.

Use Newton’s first law of motion to explain how wearing a seat belt in a moving car could help preventinjury.

Answers

Newton's first law of motion states that an object in motion tends to stay in motion unless an opposing force stops it.
since you are in motion while riding your car,  If you suddenly run into some kind of obstruction, your body will continue to move in the direction it was going.  Seat belts are very important because they're there to stop you. Not wearing seat belts would probably cause injury or death because, you could  go right through your front window unless you have them worn.
