A person who specializes in the study of animals is called a zoologist. Zoologists who study certain kinds of animals have their own names.
Because in that way we keep thinking about them. How can you forget something when you're thinking about it?!
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
Answer:
At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.
Answer:A
Homozygous means both alleles are the same. This leaves A and B
Only choice A has heterozygous(different) alleles for offspring,so it is the right answer
