The answer is (A. mitosis)
Answer:
The correct answer is option a, that is, sympatric speciation.
Explanation:
Speciation, which takes place when two groups of similar species live in a similar geographical location, however, they evolve distinctly unless and until they no longer interbreed and are regarded as different species is termed as sympatric speciation.
Sympatric speciation is not similar to other kinds of speciation, in which the formation of a new species takes place when a population gets differentiated into two groups because of migration or geographic barrier. The sympatric speciation can be witnessed in various distinct kinds of species. Thus, the given case of monkeys is an illustration of sympatric speciation.
Answer:
A response is a _reaction to a stimulus. • A stimulus is anything that can cause an individual to respond or react. • Stimuli can be _internal or external.
Explanation:
A change in the cellular make up of an organisms due to response or reaction to a stimulus is called a response. This response can be due to a stimulus inside the body , or due to effect of an external ( stimulus) object on the body-stepping on a sharp pin.
In either cases, the stimulus is receive by the receptors, which transfer the stimulus through the sensory neuron to the inter neuron in the CNS, for the motor neuron to bring an effective response at the effectors.
Answer:
The structure of mitochondria contains the foldings in the inner side called "cristae" which increase the surface area of the mitochondria. The cristae are important to mitochondria as well as cell as cristae embody the ATP synthase enzymes which help in the formation of the ATP molecules.
Heart cells require more energy to pump the blood from the heart to the body so it needs a more mitochondrial number in the cells with more infoldings to synthesize more ATP.
Answer:
A. A prokaryote lacks a well-defined nucleus.
C. A prokaryote lacks cell organelles.
Explanation:
A prokaryote has DNA or RNA just floating in the cytoplasm. There is no nucleus to hold them inside. A prokaryote also lacks a mitochondria and other organelles, so it is different from a eukaryote.
