<u>Answer:</u> C. A plant absorbing carbon dioxide during photosynthesis
<em>A plant absorbing carbon dioxide during photosynthesis can be considered as assimilation in the carbon cycle.
</em>
<u>Explanation:</u>
<em>The process of carbon fixation is called assimilation in carbon cycle. In the atmosphere carbon occurs in the form of carbon dioxide. </em>
By the process of carbon fixation this carbon dioxide is converted into carbon compounds and these act as source of energy in an ecosystem.
Photosynthesis is an example of carbon fixation process. Other processes like chemo-synthesis also fix carbon. <em>Majority of carbon fixation takes place in marine environments. </em>
Answer:
The correct answer is - the cell membrane.
Explanation:
When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.
Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.
Answer:
The node
Explanation:
Each branch point on the cladogram represents where species split off into new ones. The node represents the last point at which 2 new species shared a common ancestor.
I think the answer here is neurons, the nerve cells
