Each cell has a job. Some form together to become skin, and some are your organs. Others are your blood and bone, And most importantly some are your defense. Without one of these cells, humans wouldn't exist, no bone cells, we wouldn't move. No blood, we die. No fighting bad bacteria, we die. As you can see each one is important :)

What kind of map is a rectangular representation of earth but she was accurate directions but distorts the sizes and distances
Anna [14]

The correct answer is - Mercator projection map.

The Mercator projection map is a cylindrical type of map that represents the Earth in rectangular manner. While the map may seem as a nice representation of the Earth, and it has accurate directions, it also has some flaws. The biggest flaw of this map is the distortion of the sizes. The distortion is non existent on the Equator, but as it moves north and south of it towards the poles, the distortion is constantly increasing. This projection is not made to be able to cope with the increase of the scale, especially when it it is infinite at the poles.

Because of this, on this map, Greenland looks very similar in size with Africa, even though in reality it is around 15 times smaller.

Tcecarenko [31]

Among the typical midlife changes for men is an Increase in prostate size.

A portion of the fluid that carries sperm during ejaculation is produced by the prostate, a gland. The urethra, which is the tube through which urine leaves the body, is surrounded by the prostate gland.

As you get older, your chances of having an enlarged prostate go up. Because BPH is so common, it has been said that if a man lives long enough, he will all have an enlarged prostate. Many men over 40 have a small amount of prostate enlargement. The condition affects more than 90% of men over the age of 80.

1.A scientist wants to prevent a culture of live cells from producing a particular protein. Which of the following will the scie
SIZIF [17.4K]

1. Answer:   A

Explanation: For a cell to form proteins, the specific types of proteins are coded for by the genes in DNA (found in the chromosomes of the nucleus). To produce proteins, the genes are first transcribed by RNA polymerase to form messenger-RNA. The mRNA is then translated into proteins by ribosomes in the cytoplasm of the cell.

2. Answer: B

Explanation: Translation of genes into proteins is dependent on the sequence of nucleotides. They are translated in sequences of 3 nucleotides known  as codons. Therefore adding a nucleotide on a piece of DNA causes what is referred to as a frame-shift mutation. The 3 sequences (of codons) is interrupted and shifted by one nucleotide. Therefore, the codons change and the amino acids translated will also change.

3. Answer: A

Expanation: Producers are significant in a food chain because they incorporate the energy of the sun into the food chain. This is why they are at the base of the food chain and have the largest biomass. They are consumed by primary consumers which are consumed by secondary consumers which are consumed by tertiary consumers and so on.  

4. Answer: D

Explanation: Plants are consumed by herbivores. Therefore, a decrease in plant population due to drought was resulted to decrease in herbivore population. This is due to stiff competition by the herbivores for the scarce plant population. Carnivores consume herbivores. Due to a decrease in the herbivore population, then the carnivore population would also decrease.

5. Answer: A

Explanation: Burning of fossil fuels emits carbon dioxide gas which is a greenhouse gas. Greenhouse gas traps infrared wavelength of lights hence warming up the atmosphere, causing global warming. Reduction  in use of fossil fuels will hence alleviate an increase in global temperature hence protect coral in the oceans from bleaching.
