The answer is A. Oligotrophic lakes are clear and hence have little vegetation in them (hence no net primary production) that could initiate the process of eutrophication. Eutrophication is brought about when bacteria break down the high amount of organic matter hence reduce the oxygen supply in the waters.

The oxygen sag curve is related to all of the following except oligotrophic lakes.

Further Explanation:

Oxygen sag curve is obtained when the amount of the dissolved oxygen inside a river in which pollutant and sewage is released is plotted against distance downstream from a sewage pipe. In this small amount of water is taken from downstream and upstream areas from sewage outlet. The occurrence of sewage in water reduces the content of the oxygen into the water and increases the BOD. It is referred as biochemical oxygen demand. This develops due the activity of saprotrophic organism that mainly decomposes the organic substances of the sewage.

Oligotrophic lakes are clear and hence have little vegetation in them. Hence, there is no net primary production that could initiate the process of eutrophication. Eutrophication is a process which initiate when the bacteria break downs the very high amount of organic substances and reduces the oxygen supply in the water.

A patient's HDL, LDL, and triglyceride levels are 62, 77, and 60, respectively. What is the patient's total cholesterol score? S

Len [333]

Answer:

Total cholesterol score is 199

199 is high cholesterol score especially as it very close to 200. The patient should adopt diets that do not include high cholesterol food

Explanation:

a. Firstly, we want to calculate the patient’s total cholesterol score.

To get this, we use a mathematical approach.

Mathematically;

the total cholesterol score = HDL + TDL + Triglyceride = 62 + 77 + 60 = 199

The patient’s total cholesterol score is 199

b. As a doctor, I will advice the patient on the status of these measurements. Using the scale of cholesterol level, a measurement of total cholesterol = 200 represents a high cholesterol level. Since 199 is very close to 200, the patient is at a risk of high cholesterol levels and thus needs a dietary change.

Which statement best explains why the development of a new area of science can lead to changes in a theory? A.A new area of scie

Levart [38]

Hey there!

It is mostly like "B". A new area of science promotes experimentation from a different point of view because everything else is explains why the development of the new area of science which could lead to change in a particular theory but they aren't quite the "best" one

SO, that is why $\boxed {Option B}$ is mostly likely your result

Good luck on your assignment and enjoy your day!

telo118 [61]

Answer:

Trisomy X, also known as triple X syndrome and 47,XXX, is characterized by the presence of an extra X chromosome in each cell of a female. Those affected are often taller than average.

Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby.
