Answer:
Bad and good cholesterol.
Explanation:
The bad cholesterol generates low density liproprotein which is dangerous to the body system , hence the name "bad cholesterol". Most heart related diseases are linked to excess of the this cholesterol in the body. while the good cholesterol generates high density liproprotein that helps in discharging bad cholesterol from accumulating in the arteries .
Answer:
B)make many copies of an organism’s DNA sequence so a small number of organisms will become large enough to be identified.
Some wildfires like hurricane, droughts, and natural disasters like wildfires can act as density independence limiting factors. It affects all populations and similar ways no matter what the size of the population is and density.

Some of the symptoms that may be experienced by Shiela after a stroke affecting the frontal lobe will include;
- Difficulties in speech and language
- Muscle weakness that would be characterized by cases of incontinence
- Changes in personality and behavior (characterized by episodic periods of mood swings and outbursts, apathy, irritability)
- Reduced creativity and thinking capacity hence reduced capacity to solve problems.
The fact that there is little diversity in the form of mc1r gene we can inferred that it is an that it is an advantageous trait to protect from extreme sun and lack of diversity is due to the negative selection.
- The MC1R gene give order for formation a protein called the melanocortin 1 receptor. This receptor plays very important role in normal pigmentation. The receptor is found on the surface of melanocytes, these cells secrete a pigment called melanin. Melanin is that the pigment that gives skin, hair, and eyes their colour.
- Negative selection works to get rid of deleterious alleles from a population in another term that describes this is often “purifying selection.”
- Positive selection leads to directional selection. Positive selection for a beneficial allele can increase the frequency of neutral variants neighbouring the beneficial allele; such genetic hitchhiking may end in a large area of homozygosity (i.e., loss of diversity during a large area of a chromosome) due to a highly advantageous mutation and is referred to as a selective sweep.
