The answer is C because hydrogen bonding can only take place in polar molecules with hydrogen atoms
Answer: In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... This enables better survival and reproduction compared with other members of the species, leading to evolution.Adaptations are the result of evolution. ... Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation. For example, imagine a bird species.
Explanation:
Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is the process in which an organism adapted according to environmental changes for its survival and increase there number by reproduction.
Charles Darwin was first to explain its activities and now it's established as the major process behind the evolution.
Aye aye, primate adapted according to the environment and develop a character for its survival over a period of time. Natural selection is the connection between structure and function.
Thus, the correct answer is - natural selection.
Answer : The correct answer is-
This means that they cannot produce viable offspring and are reproductively isolated.
Mule (which is a sterile that is infertile animal) is produced by mating of horse and donkey.
According to Biological species concept of Ernst Mayor, a group of organism belong to same species if they produce viable and fertile offspring.
This means that organisms belonging to different species are reproductively isolated that is unable to produce viable and fertile offspring.
Thus, reproductively isolated is the right answer.
