Lake Tahoe in Devada suffered from a severe eutrophication damage until control and remediation activities were carried out. Option C is correct.
What is eutrophication?
The term eutrophication refers to the biological process produced in water by an oversupply of nutrients or organic matter.
Human pollutive activities are closely related to this artifical eutrophication and, in several cases, are the cause.
Nutrients, mainly compounded with nitrogen or phosphorous, favor phytoplankton multiplication, especially cyanobacteria. Primary productivity enhances due to the sharp increase in these microscopic organisms.
The overgrowth impedes light reach deeper areas, affecting the biota living there. Sedimentation is caused by the death of plants and algae that sink to the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
Both processes, phytoplankton overgrowth on the surface and fermentation on the bottom, originate toxic compounds that damage the animals.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
Decomposition and fermentation processes increase, producing a bad smell.
This whole cycle continues as long as cyanobacteria are present.
Among the main human activities responsible for eutrophication we can mention tourism, agriculture and the cattle industry, and the lack of controlled organic waste treatment.
This what occurred in the Lake Tahoe, in Devada, after the impact caused by tourism, deforestation, and the cattle industry.
This lake suffered from a severe eutrophication damage until control and remediation activities were carried out.
The correct option is C. Lake Tahoe in Devada.

What is immune system?The Immune System composed of different types of cells and molecules, which protect our body against pathogens.
Pathogens are defined as everything from parasites to fungi, bacteria, viruses and haptens. Haptens are molecules that may cause an immune response when they come in contact with a protein.
These cells and molecules are distributed in all the tissues of the body as well as lymphoid organs, which eliminate or prevent microbial infections to decrease the growth of tumors and start the repairing process of damaged tissues.

What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

2. Constant and unique
Explanation:
The rate at which a parent atom creates daughter atoms is always constant and unique. The process of cell division is a unique occurrence that happens with eukaryotic cells. These parent atoms go through the different phases at a constant phase, but when interruptions in the divisions happen, mutations and abnormality in the cell will take place.

C. Females choose mates, resulting in large males.
D. Polygenic traits change due to directional selection.
Answer:
i think the answer is b
Explanation:
B. Allele frequencies change randomly each generation
Answer:
B
Explanation:
Genetic drift is the alteration of different genotypes in a small population which can cause individuals and organisms getting wiped out, not being able to reproduce, and disappearance. Allele frequencies change randomly each generation in a gene pool (collection of different genes present in a particular population: species in this gene pool have a choice to leave the gene pool or die out).
How many moles of LiCl are contained in 50.0 mL of 0.600 M solution?
Answer:
0.0300 moles LiCl
Explanation:
You can find the amount of moles using the molarity formula. The general structure looks like this:
Molar Concentration (M) = moles / volume (L)
You were given the molar concentration and volume in milliliters. Once you convert the volume to liters (by dividing by 1,000), substitute the values into the molarity formula. Then, you can simplify to find moles. The final answer should have 3 sig figs according to the given values.
50 mL / 1,000 = 0.0500 L
0.600 M = moles / 0.0500 L
(0.600 M) x (0.0500 L) = moles
0.0300 = moles
