Answer: Option A.
The two types of chlorophyll are chlorophyll A and B.
Explanation:
Chlorophyll is the green pigments present in chloroplast (organelles) that is found in plants which is used for photosynthesis by reacting with carbon dioxide and water to produce carbohydrates. The two types of chlorophyll are; chlorophyii A and chlorophyll B.
Chlorophyll A is the primary photosynthetic pigment that absorb energy from blue- violet light and orange red lights wavelengths.
Chlorophyll B is the accessory pigment to receive energy and transmit it to chlorophyll A. Chlorophyll B absorbs energy from green lights wavelengths.
Answer:
Phylogeny: It is related to evolution dealings in the evolutionary development of a species. It is represented by different ways vertical or slanted.
Phylogenesis: It refers to the evolutionary relationships among species.
Phylogenetics: It is determination or estimation of evolutionary relationships among groups of species, organisms and genes.
Phylogenetics is a field of biology which is used to find relationships among different organisms. This relationship is showing through a tree (used to model actual evolutionary relationship of organisms). Ancestral divided into two descendant species because closely related organisms are shown in near branches. If there is too much divergence between two species its mean they are not closely related.
The history of speciation (one species becomes divided into more than one new species) tells us how these species are related to each other. If they evolve to be separate species relatively recently then they are "closely relative" similarly if they evolve to be separate specie long above then they are "distant relatives". For example orthologs are genes in different species that evolved from common ancestor gene by speciation; they retain same function in the course of evolution.
Explanation:
Si.
The fiber in diet pills, performs as a bulking mediator in
the large intestine and not in the stomach. Diet pills should not be used in
high doses, because diet pills come with different side effects, which causes
illnesses, like heart attack or even stroke.
The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.
