<span>The answer is B cells. They form part
of the humoral immune response of the adaptive immune system. When B cells are activated
due to the presence of a antigen in the body, the plasma B cell produce
antibodies and release them into the circulatory system. </span>
The nervous system in a frog controls the activities of the organs of the body. It also would regulate the internal environment in one's body. All the organs which are also the same parts of nervous system of a vertebrate are present in a frog. The brain,spinal chord,the sympathetic and para sympathetic nerves,cranial nerves,spinal nerves,cranial nuclei and ganglia.
Their source of carbon. Autotrophs obtain their carbon from inorganic sources such as from atmospheric carbon dioxide. Examples of autotrophs include plants, and euglena ( a protist).
Heterotrophs on the other hand, obtain their carbon from organic sources such as other organisms. Examples of heterotrophs include all secondary consumers, and decomposers.
The answer is 14 since there is 28 in the zygote.
<h2>Wet versus Dry habitats</h2>
Explanation:
- Plants from wet habitats have a relatively large number of stomata and thin cuticle
- Plants from dry habitats have a less number of stomata and thick cuticle
- Stomata helps in exchange of gases whereas cuticle reduces the loss of water
- If water is more then plants have large number of stomata which helps in great access to water and increases support for herbaceous tissues
- In case of dry habitat conditions are not favorable with regard to water hence a thick cuticle is required to minimize the water loss while in wet habitat water is abundant hence they have a thin cuticle
A.Vascular plants have a relatively large number of stomata
B. Plants from wet habitats include white lotus,water lily
C. Plants from dry habitats include xerophytes for example cactus,oleander
