I would say Genus and Species because they are what comprise the specific epithet or every organism.
<u>Pollination:</u>
Pollination is a process of fertilization. The pollen is produced by the anther of the stamens in flower. The anther is the swollen part of the stamen. There is a pollen sac which produces the pollen grains. These pollen grains are small coarse substances.
<u>Working process of pollination:</u>
- The small grain are made of one or few cells. They produce male gametes for fertilization.
- Pollination happens combining the male and the female gametes.
- For it to happen the pollen should be linked from the stamen to the stigma and finally it produces seed and fruit.
The rock cycle is not a typical pattern found in the Earth system.
Answer:
The nervous system together with the endocrine system enables the organism to perceive the variations of the (internal and external) to disseminate modifications that these variations produce and execute the answers appropriate to maintain the internal body balance (homeostasis). The autonomic nervous system divides into the sympathetic nervous system and parasympathetic nervous system. In general, these two systems have opposite (antagonistic) functions, they correct the excesses of the other.
For example, if the sympathetic system speeds up too much the heartbeat, the parasympathetic system kicks in, slowing down the heart rate. If the sympathetic system speeds up stomach work and intestines, the parasympathetic comes into action to reduce the contractions of these organs. The sympathetic generally stimulate actions that mobilize energy, allowing the body to respond to stressful situations. For example, the sympathetic system is responsible for the acceleration of heart rate, by increasing the blood pressure, the concentration of blood sugar and by activating the general metabolism of the body. On the other hand, parasympathetic mainly stimulates relaxing activities, such as reductions in the heart rate pace and blood pressure. One of the main differences between the sympathetic nerves and parasympathetic is that the postganglionic fibers of the two systems usually secrete different hormones.
