The food in the protein group and dairy group are high in saturated fats and cholesterol, it raise LDL in blood.
<h3>
What is cholesterol?</h3>
Cholesterol is a waxy like substance synthesized from two sources such as liver and from animals like meat, poultry, diary product.
There are two types of cholesterol, one is bad called LDL cholesterol and second one is good called as HDL.
LDL narrow down the arteries by depositing fats in it, the condition known as atherosclerosis which leads to increase in risk for heart attack, stroke and peripheral artery disease.
On the other hand, HDL protect against heart attack and stroke
Third component called triglycerides are the common type of fat act as a reservoir of excess energy.
Hence, LDL is the correct answer.

Answer:
B) Identifying the minerals within it
Explanation:
Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date the age of rock layers.
Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution
<h3>What is Fahrenholz's rule ?</h3>
The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.
This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.
when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.

B water pollution is the answer
You have given no demonstration based on your microscopic investigation so I cant tell you the answer to the question. I will try to help you by elaborating how to decipher..
Three terms hypotonic, hypertonic and isotonic are used when referring to two solutions separated by a selectively permeable membrane.
The hypertonic solution has a great concentration of OAS than the solution on the other side of the membrane. It is described, therefore, as having a great osmolarity. The hypotonic solution has a lower concentration of OAS, or osmolarity, than the solution on the other side of the membrane. When the two solutions are at an equilibrium, the concentration of OAS being equal on both sides of the membrane, the osmolarities are equal and are said to be isotonic.
The net flow of water is from the hypotonic to the hypertonic solution. When the solutions are isotonic, there is no net flow of water across the membrane.
If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells.
So, look at the information and data you have on your microscopic investigation and use these guidelines to tell you which is which.
