Answer:
space between gas molecules
Explanation:
as the altitude increases the air density decrease because of weaker gravity and these led to more distant of air molecule and the space between gas is increased
Answer:
5: The phenotype for both parents is being tall.
6: 25%
7: 50%
8: 25%
Explanation:
5: We are shown that tall plants are dominant over short plants, and the genotypes of both parents are Tt (tall, short). This means that both parents will be tall.
6: The Punnet Square shows us that 1 out of 4 offspring are TT, 1/4 is 25%
7: The Punnet Square shows us that 2 out of 4 offspring are Tt, 2/4 is 50%
8: The Punnet Square shows us that 1 out of 4 offspring are tt, 1/4 is 25%

Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
