The environmental impact of transport is significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide.
Answer:
probability that the A2 allele will drift to fixation is 30%
Explanation:
given data
population = 100
initial frequencies A1 = 0.7
initial frequencies A2 = 0.3
solution
we know that initial A1 frequency and A2 frequency and here the fixation time is referred as amount of time
so it take to fix allele in a certain population
and A1 & A2 is neutral for fixation
so that here fixation probability
it is neutral so change allelic frequency by the no chance of the occurrence of an mutation
so here probability that the A2 allele will drift to fixation is
A2 allele will drift to fixation = A2 × 100 ...............1
A2 allele will drift to fixation = 0.3 × 100
A2 allele will drift to fixation = 30%
so correct answer is 30%
Noise is an unwanted signal which interferes with the original message signal and corrupts the parameters of the message signal. This alteration in the communication process, leads to the message getting altered. It is most likely to be entered at the channel or the receiver.

Answer:
The correct answer is B. hypothyroidism
Explanation:
In hypothyroidism, the thyroid gland is not able to maintain an appropriate level of thyroid hormone in the blood. Thyroid hormone plays an important role in body metabolism and it also helps in proper growth and development of the body.
For the synthesis of thyroid hormone iodine is a very necessary mineral. 70-80% of all the iodine in the body is present in the thyroid gland which helps in making thyroid hormone. Iodine is obtained through diet and absence of iodine in the diet can lead to hypothyroidism in the body.
