The four lipoproteins that transport lipids throughout the body are globular structures composed of a lipid center surrounded by a coat of protein. Each lipoprotein has a different density, determined by the ratio of protein to lipid; the more protein each lipoprotein contains, the higher its density. The density determines how the lipoprotein functions. Match the below mention lipoproteins with the given Lipids.

a. This lipoprotein contains the most cholesterol of all lipoprotein and about 25% protein.
b. This lipoprotein contains a mixture of lipids, most of which is 60% triglycerides and about 10% protein.
c. This lipoprotein contains the most triglycerides and the least protein.
d. This lipoprotein contains 50% of its composition as protein and other 50% is composed of triglycerides, cholesterol and phospholipids.

Lipids:
1. Chylomicron
2. VLDL
3. LDL
4. HDL
5. Micelle

•A is matched with 3

• B is matched with 2

• C is matched with 1

• D is matched with 4

Explanation:

•Chylomicrons: are lipoproteins that contains the most triglycerides and the least protein. They are used for the transportation of  dietary lipids to help prevent hydrophobic conditions. They are produced in the intestines during digestion

• VLDL (very low-density lipoproteins) : these are lipoproteins that contains a mixture of lipids, most of which is 60% triglycerides and about 10% protein. The very low density lipids contained in this lipoproteins are used to deliver triglycerides from liver to other tissues in the body.

• LDL (low-density lipoproteins):  these are the lipoproteins that contains the most cholesterol of all lipoprotein and about 25% protein. They are specifically use to transfer the cholesterol to the body cells.

• HDL (high-density lipoproteins): these are the lipoproteins contains 50% of its composition as protein and the other 50% is composed of triglycerides, cholesterol and phospholipids. They transport back the cholesterol to liver.

•Micelles: they are collection of fatty elements that aids with fat absorption.

the answer would be d

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
