Explanation:

Surgical removal of Thyroid gland will lead to hypothyroidism.

Rufina [12.5K]

Answer: Hey again!

Option (a) is the correct answer.

Explanation:

Elemental form of carbon means the pure form of carbon, that is, carbon is present in its natural form.

An elemental form also means that the pure atoms are not attached to any other atom.

For example, diamond is an allotrope of carbon in which there are only carbon atoms attached to each other and no other atom is present in it.

Whereas methane has carbon and hydrogen atoms attached to each other therefore, it is not an elemental carbon. And proteins include different atoms attached to each other.

Thus, we can conclude that diamond is an example of elemental carbon.

HELP!! photosynthesis and cellular respiration basics venn diagram
Gre4nikov [31]

Cellular respiration and photosynthesis are functionally interrelated. These metabolic pathways exhibit interchangeable reactants and products.

<h3>Cellular respiration and photosynthesis</h3>

Cellular respiration refers to the metabolic reactions by which aerobic cells produce energy in the form of ATP and carbon dioxide by using the energy of chemical bonds of foods (eg., glucose) and oxygen.

Photosynthesis refers to the metabolic reactions by which plant cells produce simple carbohydrates (glucose), water and oxygen by using carbon dioxide and energy from the sun.

In consequence, oxygen and carbohydrates are the products of photosynthesis, whereas these materials are the reactants of cellular respiration (thereby both pathways are interrelated).
