1. change
The natural selection is a process that occurs as a direct consequence of the living conditions in the environment. When the environment starts to change though, the organisms that live in it face a big challenge. They either have to change, adapt to the new conditions, and thus survive, or if they are not able to do so, to die out. This is the biggest evolutionary pressure for the organisms, and while some come out as winners from it, many others die out .
2. variation
In order for the process of natural selection to occur, the population needs to have some genetic variation. The environment is the ultimate push factor, but if the population doesn't have genetic variation in it, than the species will die out. The genetic variation is very important as in that way the individuals choose who will they mate with, in accordance with their traits, so that only the advantageous traits can be passed on to the next generation, so that it can be more competitive in the environment.
3. traits
The natural selection is a very simple process. The individuals of a population, when choosing a mate, look for the individuals that exhibit traits that are advantageous for survival. Mating with individuals with traits that are advantageous guarantees that the offspring will inherit those traits, thus it will have higher chances to survive. The individuals that do not have advantageous traits though will be avoided as mating partners, and that would rapidly lead to their decline and elimination from the gene pool, as they will not have any offspring to continue their line.
Answer:
Krishna is probably suffering from vitamin A deficiency.
Explanation:
Vitamins are considered micronutrients as the body only needs small amounts of them to function perfectly.
Vitamin A is an indispensable element for ensuring not only visual acuity, but proper growth and tissue differentiation. Lack of this vitamin can cause blindness, poor night vision, xerophthalmia, also called dry eye or keratoconjunctivitis sicca, a disorder that is not only characterized by changes in tear production or composition, but also produces dryness of the skin, cornea, conjunctivae and the appearance of small white spots in the sclera (Bitot patches). In the most severe cases of xerophthalmia, corneal ulceration and necrosis may occur.
According to the symptoms that Krishina and her parents have, we can say that she is likely to be vitamin A deficient.

ANSWER 1: The impulsive decision that I took was buying a car.
EXPLANATION: In Summer 2016, I took the decision to buy a car which was impulsive in nature. The car was being offered at a huge stock clearance discount by the dealer and the car was also a limited version much loved by my father. So, to get the last minute deal I bought the car within a week's notice.
ANSWER 2: The decision was taken because the car was limited and it was a huge stock clearance from the dealer's end after which the car's production was stopped and it won't be available. The car being my father's favorite, I wanted to gift it to my dad.
ANSWER 3: The consequence of the decision was I had to get loan from finance company with a tenure of 5 years. The car was well out of my budget. I made a down payment of whatever savings and I got my loan.
ANSWER 4: If the decision was to made all over again, I would prefer to calculate my finance first. I would prefer a used car to buy for me or my dad rather than running for last minute deals from the dealers. The used car will be well within my budget and would also be offering the same features as the new car would have been.
