Answer:

Explanation:

Air at both poles sinks because it is more dense, it then flows back towards the equator where it is warmer and the air becomes less dense and rises. It’s called convection current.

ETA: I just took this quiz and got the answer I chose right, just didn’t want others coming here for help to get it wrong due to the first person saying the answer was A, which is the exact opposite of what happens.

Why is it significant that all biological systems use l-amino acids and d-sugars?

-Dominant- [34]

<span>L-amino acids and D-sugars are part of every protein.
All proteins are made up of them.
The fact that all biological systems use L-amino acids and D-sugars is linked with the idea that certain groups of organisms come from a common ancestor because. The reason is that if the common ancestors used L-amino acids and D-sugars, than its offsprings use them as well.

Which diagnostic test is used for the direct visualization of ligaments, menisci, and articular surfaces of joints?

Sati [7]

Arthroscopy is done for direct visualization of the ligaments, menisci, and articular surfaces of the joints. Thus, option A is correct.

<h3>What is the role of ligament?</h3>

Ligaments are type of connective tissue which help to connect bones, joints and organs. It provide support internal parts of the body.

It is made of a band of connective tissue, collagenous fibre and spindle-shaped fibrocytes which is an elastic fibers.

Ligaments holds bones together, stabilize it, provide strength to joints etc.

By the use of Arthroscopy doctors can diagnose and treat the joint’s structural problems like any dysfunction. Hence, Option A is correct.

In bacterial cell division, the cell divides into two nearly equal halves. This process is referred to as:

Step2247 [10]

In bacterial cell division, the cell divides into two nearly equal halves. This process is referred to as mitosis.

To answer the question, we need to know what cell division is

<h3>What is cell division?</h3>

This is the process in which parent cells divide into two or more daughter cells.

There are two types of cell division namely

Mitosis and
Meiosis

<h3 /><h3>Mitosis</h3>

Mitosis is the process in which non-reproductive (somatic) parent cells divide into two daughter cells that have the same number of chromosomes as the parent cell.

<h3>Meiosis</h3>

Meiosis is the process in which reproductive parent cells divide into four daughter cells with half the chromosoes of the parent cells.

From this, we see that cell division in which the cell divides into two nearly equal halves is refered to as mitosis.

So, in bacterial cell division, the cell divides into two nearly equal halves. This process is referred to as mitosis.
