Answer:
Iodine
Explanation:
Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.
If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.
Answer:
little pouches
Explanation:
the aleveoli are like small balloons, but not large ones. they exchange oxygen and carbon dioxide molecules (so they contain small amounts of air like a SMALL balloon, or in this situation a small pouch).
In plants, the chloroplast is necessary to photosynthesis, and mitochondria contain enzymes responsible for producing energy
There are a few different organisms that could potentially contain genes encoding enzymes that can fix carbon from 
. However, one of the most likely candidates would be plants. Plants have a unique ability to convert into useful organic compounds, and they typically have a large number of genes encoding enzymes involved in this process. Therefore, it is reasonable to believe that plants may also have genes encoding enzymes that can specifically fix carbon from .
<h3>
How do plants convert into useful organic compounds?</h3>
Plants are able to convert into useful organic compounds through the process of photosynthesis. This process occurs in the chloroplasts, which are organelles found in the plant cells. In photosynthesis, the plant uses sunlight to convert and water into glucose and oxygen. The glucose can then be used by the plant for energy, while the oxygen is released into the atmosphere.
