A population of organisms must exist. There must be variation among the members of the population. There must be a mechanism by which some members of the population can produce more offspring than other members. There must be a mechanism by which the variation among members of the population is passed on to their offspring.
A. for cooking food and transmitters
Answer:
a) Radius decreases
Explanation:
Resistance of any conductor is directly proportional to the length of the conductor and inversely proportional to its cross-sectional area.
So, in mathematical terms, the resistance is written as
= ρ
As we know, cross sectional area is related to the radius of the conductor so if the radius of the conductor is decreased, the cross-sectional area will also decrease.
And if the cross-sectional area will decrease, the resistance will increase.
Thus decreasing the radius, increases the resistance.
The place where an organism lives and that provides the things it needs to survive is its habitat.
