Answer:
Explanation:
The temperature and pressure on the earth's surface is lower than that below the earth's surface. Generally, temperature and pressure increases as you move/dig down the earth's surface. This increase in temperature and pressure causes the earth's sediment (below the earth surface) to form a compact solid rock - this process is known as lithification.
It increases the chances of lions surviving a natural catastrophe.

Explanation:
1). Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing.
2) is pic
Answer:
E) ecological niche
Explanation:
Every species on the planet, be it a bacteria, animal, or a plant has its own ecological niche. Basically, the ecological niche is the position and role that an organism is occupying in the environment. Further, this means that it is a combination of all the activities of the organism, how it uses the biotic and abiotic factors in the environment it leaves, how it finds food and how it feeds, its shelter, reproduction, the manner in which it survives. All of that sums up the species and its role in the environment, thus its ecological niche. There are countless ecological niches, as there are millions of different species, all of which have their own way of living, feeding, reproducing, interactions with the biotic and abiotic factors, resulting in numerous unique ecological niches.
Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
