Answer:
Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.

The right answer is human embryonic stem cells (hESCs).
Emerging embryonic stem cells are endowed with two important capacities: that of multiplying to infinity, by simple division (self-renewal), and that of giving birth to all types. of cells of the body (pluripotency).
These properties open up many perspectives, not only for regenerative medicine (including cardiology) but also for the study of genetic diseases and the development of treatments.
Answer:
Asexual: A-binary fission, D-fragmentation
Sexual: B,C
Answer:
Muscle tissue and neural tissue
Explanation:
Excitability refers to the ability of muscle and nerve cells of the respective tissues to respond to a stimulus and generate an action potential. Both muscle cells and neurons respond to a stimulus and convert it into the action potential.
Action potential refers to the electrical signal. Propagation of action potential along the membranes of these cells results in muscle contraction and functioning of neurons.
The membrane potential of these cells changes in response to the stimulus and the changed potential is propagated to the other cells.
Answer:
The correct answer would be the option B.
The carrying capacity of an ecosystem refer to the maximum number of plants, animals, insects, and crops an ecosystem can support without getting any degradation.
Carrying capacity of different species may vary within an ecosystem.
It is determined by different factors such as food availability, shelter, water supply, et cetera.
