The answer is stroke. This means that formation of plaque in the blood vessels that serve the brain cause thickenning of the inner walls of the vessels. When the plaque ruptures, a blood clot forms and blocks blood passage to a particular region of the brain served by the vessel. This stifles oxygen supply to the respective part of the brain leading to the death of the cells in the region.

Sonbull [250]

Answer:

(B) Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant

Explanation:

Living beings exhibit various changes in the behavior and niche to make themselves better fitted to the conditions of their habitats.

Boreal owls feed on the other smaller mammals such as mice and shrews. These organisms that serve as their prey are relatively less abundant in the habitat. To ensure the food availability, the boreal owls occupy a larger area so that they can catch their less abundant food organisms.

In the habitats where the prey species of boreal owls are present in a larger number, these owls occupy smaller regions since the food organisms are easily available.

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)
