When a cell divides, each daughter cell must receive its full complement of genetic material in the form of chromosomes containing DNA, or deoxyribonucleic acid. A chromosome is made up of two long strands of DNA and several types of proteins . A DNA strand is composed of a long backbone of sugar and phosphate units . One of our different nucleotide bases -- A, T, C or G -- hang off each sugar unit. The sequence of the bases encodes genetic information. The three steps in the process of DNA replication are initiation, elongation and termination

Which of these is an example of land degradation?
Nikitich [7]

The correct answer is - D. A drought kills all the plants in an area, leaving bare land.

If there's such a big drought that will manage to kill off all the vegetation in an area and leave bare land behind it, than the land will be degraded in no time. Once the land is left without its natural protection that the roots of the vegetation provide, the land will be exposed to high rates of and erosion. The erosion will be very quick and the top layers of the soil will be moved away with every wind and rainfall that will appear. That will degrade the land to a very high degree, making it totally unusable and it will need lot of time to eventually recuperate.

Which of the following represents organisms in a food chain?
Lisa [10]

Answer: c seeds, mice, snakes

Explanation:

<u>a hawks, owls, eagles NO</u>

These animals all eat some form of meat, and they are on the top of all of their food chains. If you put these animals in a room with no food, there'd be no food chain, and they would got out at each other until there was one left, and there'd be no advatanges because 1. they can all fly and 2. they are all top consumers. The same thing goes for D except hyenas can't fly.

<u>b deer, rabbits, cows NO</u>

This is not a food chain because all of the animals are herbivore, so they only eats plants and will not eat each other.

<u>c seeds, mice, snakes YES</u>

The seeds are a producer which is to be eaten by a consumer (the mouse), and which are then eaten by the predator, the snake.

<u>d hyenas, vultures, crows NO</u>
