Answer: Option D
Explanation:
The bacterium which is known as flesh eating bacterium is known as Streptococcus pyrogenes.
The disease caused by this bacterium is an infection in which one or more than one bacterium is used to describe this disease.
This bacterium releases toxin that destroys tissues inside the body such as skin, fat, mucous.
This disease is known necrotizing fasciitis. Hence, the correct answer is Option D.
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell.
The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.
Noncoding sections are used in dna fingerprinting, as they are easily identifiable, abundant, and passed on from parent to child through genes. If you can get a relative with similar noncoding sections, then you could compare similarities in the DNA.
Explanation:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]
Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]
Explanation:
Amino acids are the building blocks of proteins. Proteins are digested in the gastrointestinal tract into peptides,polypeptides and single amino acids using hydrochloric acid and proteases. After protein digestion amino acids are absorbed by the jejunum in the small intestines and taken up by capillaries to the blood stream. They then travel in the blood to the liver, joins the urea cycle where they are metabolised for cell growth and tissue repairs.
