Answer:
1 evolution 2 natural selection.
Explanation:
Answer:
It moves by diffusion through small holes in the underside of the leaf called stomata.These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
Answer:
Founder effect
Explanation:
Genetic drift is the process of change in allele frequency in a population because of chance increase or decrease in number of particular alleles in that population. It can be caused due to may reasons like founder effect, bottleneck effect etc.
Founder effect is a phenomena where a small group of individuals migrate from the original population to some other area and start a new population. The new population will all result from this small founder population. So if by chance some alleles were present more in the founder population, the new population will also show high frequency for it. As a result the allele frequencies in the new population can differ from the original first population.
Here, the Amish population in North America was settled by a small number of immigrants from Europe. Among those immigrants many had alleles for genetic dwarfism. So when this small population grew in America, genetic dwarfism also became prevalent in them.
Answer: Mass and Velocity
Explanation: My mom is educated in all types of sciences. Therefor I have an educated guess.
The continental plates collide against each other, thus making volcanic explosions more violent, and even causing earthquakes. Sorry if it's the wrong answer... >~<
