Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
The basic ingredients used to make a thunderstorm are moisture, unstable air and lift.
Therefore it should be: A. A stationary front
Answer:
Behavioral isolation
Explanation:
The reproductive isolation refers to the mechanism which prevents the interbreeding between the organism. The mechanisms of reproductive isolation can be categorised into two types: The pre-zygotic and post-zygotic barriers.
The prezygotic isolation mechanisms are the behavioural, the habitat, mechanical and gametic isolation.
In the given question, the type of mechanism involved in the population of frog will be the "behavioural isolation" as the population of frog differ in their behaviour of mating ritual or mating calls which does not allow the frogs to mate.
Thus, Behavioral isolation is the correct answer.
Answer:
something that isnt from a living thing. Such as a table falling.
Point B because it is located in the most polluted place, where pollution concentration is 40000+ particles/cm^3
