Answer:

$\boxed {\tt 3}$

Explanation:

An element only has one type of atom and cannot be broken down by chemical means.

Let's analyze the answer choices.

1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.

2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.

3. This has one type of atoms, so it is an element.

Therefore the best answer choice is 3.

Please help to solve this question.

erica [24]

Answer:

a. Glycolysis

b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration

c. Heart tissue!

Explanation:

a. Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.

b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.

c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.

Cortisol is often referred to as a "stress hormone" because it is secreted in response to both psychological and physical stress

andre [41]

Answer:

Cortisol is often referred to as a "stress hormone" because it is secreted in response to both psychological and physical stress. This hormone also aids in blood glucose regulation. If an increase in cortisol secretion leads to an increased insulin secretion, what action do you think cortisol has on blood sugar?

Cortisol simply acts as a buffer to the blood sugar as it helps to maintain the blood level sugar in order to avoid it being raised high or reduced beyond normal rate which is highly derogatory to human's health
