Answer:
chemotaxis
Explanation:
Chemotaxis is movement of the organism in the response to the chemical stimulus.
Bacteria, somatic cells and single-cell as well as multicellular organisms direct movements of their body according to some chemicals in the environment. This is very important for the bacteria to find the food by swimming toward highest concentration of the food molecules or also to flee from the poisons.
<u>Thus, it is a process by which various cells are drawn to the target area by a microbe invader.</u>
Answer:
The options
a. sympatric speciation; vicariance
b. allopatric speciation; vicariance
c. sympatric speciation; dispersal
d. allopatric speciation; dispersal
The CORRECT ANSWER IS d.
d. allopatric speciation; dispersal
Explanation:
Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).
Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.
In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
Because the pole absorbs the heat quite readily, literally sucking the warmth from your tongue faster than your body can supply it. The saliva on your tongue then freezes (provided it is below freezing), with the resulting ice latching onto the flagpole and your very porous tongue.

<span>The lobe or cortex is the largest part of the brain, full of thought, perception, imagination. It is a thin layer of gray matter, divided into four lobes with different functions. The frontal lobe is the cortex that is further away from the cerebellum and is responsible for voluntary movements and decisions and is considered the most important lobe where personality and intelligence develops.</span>
