Answer: Carbon Dioxide (CO2)Aerobic organisms (like us!) are organisms that need oxygen. That means they consume oxygen (

)and release carbon dioxide (

).
That
carbon dioxide is the waste product that is taken up by plants during photosynthesis to create more oxygen and sugars (as "food" for the plants). This is seen in the equation for photosynthesis, where the things that are consumed by plants are on the left of the arrow, and the things produced are on the right:

6CO2 + 6H2O + light energy ==> C6H12O6 + 6O2</span>
Answer:
base substitutions and base additions or deletions
Explanation:
there are two main types of point mutational changes: base substitutions and base additions or deletions. Base substitutions are those mutations in which one base pair substitutes for another. They, again, can be divided into two subcategories: transitions and transversions.

Answer:
Calcitonin
Explanation:
Calcitonin hormone is released by the para follicular cells of the thyroid gland. This hormone works against the parathyroid hormone.
Calcitonin hormone regulates the level of calcium by decreasing the blood calcium level. This hormone inhibits the osteoclast activity of the cells and decreases the absorption of calcium in pregnant women and child. Hence, calacitonin decreases plasma calcium levels in pregnant women and children.
Thus, the correct answer is option (B).
