Water is a polar covalent molecule
One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.
Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.
Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.

Answer:
astronauts are brought back to by a Soyuz capsule. The Soyuz capsule has a curved ablative heat shield that is used to prevent heat from building up and penetrating the crew cabin.
Answer:
Denitrifcation
Explanation:
<em>Thiobacillus dentrificans</em> is the gram-negative bacteria that is considered the chemoautotrophic according to its mode of nutrition.
The <em>Thiobacillus</em> is now used by the bioremediation scientists in the remediation of the wasteland as its ability to convert the reduces nitrogen forms that are nitrates and nitrites back to its dinitrogen state which escapes back into the atmosphere thus completing the nitrogen cycle.
This process of conversion is known as the denitrification and on the basis of this, the bacteria are named dentrificans.
Thus, denitrification is the correct answer.
