Yes, he does have family history of heart disease.
Answer:
Active transport
Explanation:
The molecules are moving from a low concentration to a high concentration across a cell membrane via a protein. ATP is used in this reaction.
We know it cannot be diffusion, facilitated diffusion, passive transport, or osmosis, because these are all passive processes. In the picture, the molecules are moving against their concentration gradient and uses energy.
It cannot be endocytosis or exocytosis, as there are no vesicles.
Active transport is the movement of molecules from a low concentration to a high concentration across a cell membrane against their concentration gradient. ATP is used to supply the energy for this process.
<h3>Lipoproteins</h3>
Explanation:
Lipoproteins are aggregate molecules of lipids and proteins which carry cholesterol in the blood. Cholesterol binds with water-soluble carrier molecules of the lipoproteins.
Based on their density, lipoproteins are classified as very low density lipoproteins (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL)
The serum lipoprotein levels are diagnostic markers to detect blood fat levels and are checked in the blood lipid profile tests.
If LDL levels are increased it indicates higher risk for heart diseases like atherosclerosis
If HDL is increased, it reflects a healthy heart and reduces the risk for heart diseases or failure
The largest groups into which living things are classified are called kingdoms
