Why would penguins, which are aquatic birds that live in polar regions, be unable to survive in a desert environment ?

Answers

because penguins need cold here look at it like this a fish lives in water why can't it live on land because it can't walk and can't breath so it would die like we can't live under water penguins can't live in a desert because penguins eat fish there are no fish in the desert and penguins live in ice bergs and enjoy swimming and sliding on there belly on ice threres no ice in the desert so therefor they would die no food because they eat fish no home and no habitat and there are a lot of snakes and stuff that would eat the penguins     

A man pushes a lawn mower with a force of 200 N across 50 meters of his lawn. How much work did the man perform?

Answers

Answer:

10,000 N-m

Explanation:

Work done is the product of force applied and the displacement occurred due to the applied force.  

Work done = Force x displacement  

= 200 N x 50 meters  

= 10,000 N-m
finding work:

w = f × d , where F, force applied and where D, distance.

W= 200 N × 50 m
= 10 000 nm or j

Does a plant grow faster in light or dark

Which of the following monomers would be used to make the double helix of a DNA molecule?

Answers

The monomers that would be used to make the double helix of a DNA molecule are the phosphorus+ sugar+ base. The correct option is A.

What is DNA?

DNA is a genetic material that is present in the nucleus of the cell. It is present in all plants and animals. This is the important material in the body that makes every individual unique.

DNA is made up of three substances. They are phosphorus sugar, which makes the backbone of the helix. The bases are present in between the helices, they are joined by hydrogen bonds.

There are two hydrogen bonds present between adenine and thymine.  There are three hydrogen bonds present between guanine and cytosine. The bases keep the two helices together.

Thus, the correct option is A, phosphorus+ sugar+ base.
