Answer:
The answer is C
Explanation: The random change in the gene pool is due to genetic drift. Remember, genetic drift occurs at a more rapid rate when the population size is reduced. The flood is a random occurrence. It could have as easily been a drought.
Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
Answer:
you wanna know what that is its atoms lots and lots of atoms and if you want to learn about something smaller than an atom learn about quantum physics
Explanation:
Answer:1) Chloroplast, mitochondrion and vacuole are the organelles
Explanation: a leaf is a organ of a plant and is not found in cells. An enzyme creates chemical reactions in the body. the DNA is just the plan on how to build the cell and how to do certain cellular processes. therefore a chloroplast, mitochondria and vacuole are all organells. also the mitochondrion creates energy, a vacuole stores food and water and a chloroplast converts the suns energy into food
The answer would be:
DNA : A A T T G C
mRNA: U U A A C G
The base pairings in mRNA is essentially the same, T to A, G to C however, uracil with substitute thymine to pair up with an Adenine base. In summary:
G to C C to G
A to U T to A
