Answer:
The statement that should help Dora evaluate whether dark chocolate is a heart-healthy choice is a group of answer choices Chocolate contains stearic acid, which does not appear to increase LDL cholesterol levels. LETTER A.
Explanation:
<em>Because consuming dark chocolate decreases oxidized LDL cholesterol in the heart and also increases HDL. The decrease of oxidized LDL means that the bad cholesterol has reacted with free radicals. The dark chocolate contain a powerful source of antioxidants that go into the bloodstream and protect lipoproteins against oxidative damage.</em>
<em>So it will improve several important risk factors for heart failure. That is the right choice for Dora.</em>
It is made of 2 hydrogen molecules and 1 oxygen molecule. The way we say that is H2O.

Answer:
Explanation:
The switch from glutamic acid to valine in position 6 of hemoglobin (HB) forms the basis of sickle cell anemia disease pathology.
Valine is hydrophobic and it's chain is shorter than glutamic acid. The lack of the carboxylic acid and shortness of valine will result in loss of the ionic interactions formed between the glutamic acid's carboxylic group and other amino acids. A hydrophobic cavity will form in the beta sheet of HB due to the short and hydrophobic structure of valine. For these reasons, the HB molecule will be less stable and insoluble in water. The insolubility is thought to be caused by fibril formation between the valine interacting with hydrophobic pocket residues of the adjacent HB molecule. This would in turn affect binding of oxygen to HB.
Is there suppose to be a question here?
Answer: Option B) 4 only.
The bacterium can be properly described as a commensal only
Explanation:
A biological association where one of the two organisms benefits while the other neither benefits nor get harmed describes Commensalism.
For instance, this bacterium derives nutrition from man, and man is neither benefited or harmed.
Thus, the bacterium is a commensal
