Answer:
Track and field requires a lot of running
Explanation:
When someone runs, blood needs to be circulated throughout the whole body. Constant blood is pushed throughout the body due to blood vessels in our circulatory system. The heart pumps faster so more blood is produced. Oxygen is needs to be reached to muscles. When someone runs, they tend to breathe heavier. Heavy breathing and more breathing is done by the respiratory system. Lungs need to filter air and therefore the respiratory system works hard as well

Answer:
A, B, C
Explanation:
When considering human impacts to ecosystems, identify the incorrect statement:
Select one:
a. cod, swordfish, halibut and mackerel populations are especially vulnerable to collapse
b. coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
c. aquaculture may provide a sustainable alternative for raising farmed fish to feed a growing human population, allowing ocean fisheries to recover
d. over half of global ocean fisheries populations have become severely overharvested within the past century
Answer:
coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
Explanation:
This is a wrong statement because coral reefs contrary to the statement is not recovering, Over-fishing an destructive fishing,(to meet up with increasing demand) are some of the human impacts reltively control by the enforcement.
But,acidification (eutrophication), and mass coral bleaching from global warming are not restricted by the enforcement of fishing quotas and are drastically reducing the population of the reefs.This in turn affecting the survival of the fishes, reducing the population,

What is the purpose of the cell cycle?
Answer:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.
Explanation:
What part of the fungus is seen in the woods or on the lawn? Please help I will mark you the branniest!
Damp conditions can bring out other types of fungi that can create more serious problems for your lawn. Brown patch, fusarium blight, and rust are a few of the diseases that thrive in wet grass.
Polypores are also called bracket fungi, and their woody fruiting bodies are called conks. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and their relatives corticioid fungi are the most important agents of wood decay.
please mark as brainliestCalculate pH a decrease of one unit on the pH scale means a solution is ten times more acidic. a decrease of two units means the solution is 100 times more acidic. how much more acidic is acid precipitation( pH = 4.0) than pure water (PH= 7.0 )
Answer:
Each unit of decrease has an exponential increase. So if you are looking at an item that has a Ph of 4 and water has a Ph of 7 —-that means it is 10 to the 3rd power more acidic or 1000 times more acidic than water.
Explanation:
A decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.
What is the effect of pH on the cell?The pH scale shows the pH from 1 to 14, where pH 7 is taken as neutral, below which the solution is more acidic, and above which the solution is more basic. The pH has an important role in the organism as it regulates the blood and maintains enzymatic function.
Hence, a decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.

Will change in ocean salinity cause a change in climate overall? Why or why not?
Answer:
Yes
Explanation:
Ocean play very important role in climate change. Change in the salinity of ocean definitely going to affect climate because changes in salinity have effect on water density.
Change in density allows changes in the movement of seawater and shift in climate pattern. if salinity will increase, water will become heavier and sink deep in ocean, which joins the currents that circulate all over the world. These currents affects the transport of heat and affect the rainfall pattern, example of such currents is gulf stream.
So, stable salt densities or salinity in the oceans keep the earth’s climate in balance.

What is the runoff pollution, and what causes it?
Answer:
Polluted agricultural runoff is a major source of water pollution globally. Agricultural runoff is primarily caused by melted snow or rainfall. It is, in essence, water that does not stay in the soil but instead flows on the surface and carries a variety of polluting elements.

Which resource is a non-renewable resources? A.fresh water B.Maple trees C.Solar Energy B.Precious metal
Answer:
Precious Metal, bc nature will not renew it and there's just a limited amount on any given planet.
Technically true for the sum of all water on the planet too, but fresh water gets renewed by cyclical processes in nature.
and solar energy (and trees for that matter) are also just renewed from our earthly perspective of space and time. stars do nuclear fusion, and this is a one-way process, single use basically.
so nothing is truly renewable, but we can't use up some things and get new supply for any given time, at least in time spans we can grasp.

Thymidine which is also reffered to as deoxythymidine, is described as a deoxynucleoside that is composed of the pyrimidine base thymine that is attached to the sugar deoxyribose. Thymidine is a nucleoside made up of pentose sugar, pyrimidine base tymine and deoxyribose, it is one of the the four nucleoside found in exclusively DNA as well as T-loop of tRNA.
Tetrahydrofolate also known as tetrahydrofolic acid can be described as part of folic acid that function as a coenzyme which aid metabolic reactions that includes nucleic acid and amino acids. It is also reffered to as one-carbon metabolism, and it's oone-carbon mechanism is associated to the histidine, serine of amino acid.

Choose the true statements about amyloid fibrils. 3 options are correct:a) An amyloid fibril typically forms from aggregates of misfolded peptides resulting from frameshift mutations. b) An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues. c) Soluble proteins that misfold and form amyloid fibrils become insoluble. d) Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease. e) Proteins that convert to an amyloid fibril structure tend to have low solubility in their native form.
Answer:
The correct answers are: b) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", c) "Soluble proteins that misfold and form amyloid fibrils become insoluble", and d) "Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.
