Answer:
c) eutrophication is typically driven by natural processes like rock weathering and nitrogen fixation.eutrophication happens when too much nitrogen enriches the soil, causing excess growth of plants and algea.
I hope this helps
When nitrogen from fertilizers seeps into soil, it frequently fosters weed growth rather than the development of native plants. The excess of nutrients caused by nitrogen washing into streams is known as eutrophication. Thus, option C is correct.
What best define about eutrophication?A surplus of nutrients in water, primarily nitrogen and phosphorus, causes a process called eutrophication. By consuming the nutrients, algae flourish, proliferate, and tint the water green.
Algae blooms can have an unpleasant odor, restrict sunlight, and in some circumstances even produce toxins.
The process of eutrophication occurs when a body of water receives an excessive amount of nutrients, which increases the growth of algae and macrophytes. It causes water bodies' dissolved oxygen levels to drop and their water quality to deteriorate.
Therefore, Eutrophication is typically driven by natural processes like rock weathering and nitrogen fixation.

What does the QRS complex represents as??
Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
Explanation:
QRS complex represents as ventricular depolarisation

Describe fluid exchange between capillaries and the interstitial fluid. Be sure to discuss the forces (pressure) that moves the fluid and the direction in which fluid moves. (4 points) In one to three sentences, describe the role of lymphatic system in this fluid exchange. (3 points) g
Answer:
Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.
The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.
Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.

Please use the following information to answer the questions below. The southern grasshopper mouse feeds regularly on the Arizona bark scorpion, the most venomous scorpion in the United States. While attempting to capture the scorpion, the mouse usually gets stung multiple times by the scorpion but does not seem to be affected. While attempting to capture the scorpion, the mouse's heart rate increases, and there is an increase in epinephrine in the mouse's blood. What nervous system division is responsible for the mouse's physiological state
The sympathetic nervous system is responsible for the mouse's physiological state.
The nervous system divides into the central nervous system and peripheral nervous system.
In the central nervous system, we have the brain and the spinal cord.
The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:
The somatic nervous system, which is the one that makes the conscious movements of our body.The autonomic nervous system consists of:-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.
-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.
In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

Psychometric scores for anxiety, depression, negative self, somatization, and hostility were combined into a single Global Severity Index (GSI). Global Severity Index was compared for 80 adolescents who were seen in the outpatient clinic for 7 different physical complaints (short stature, obesity, lack of weight gain, breast problems, genital problems, menstrual problems, and hirsutism). Report the degrees of freedom for the relevant F statistic in the numerator and the denominator. (Round your answers to the nearest whole number.)
Answer:
The correct answer is -
Numerator = 6
Denominator = 73
Explanation:
In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1
Numerator df = 7 - 1 = 6
Thus, the numerato would be - 6.
Denominator is calculated by subtracting the observation or variables from the total number of sample size.
Denominator df = 80- 7 = 73

How are human affiliative and aggressive behaviors different from what is seen in nonhuman primates? Provide specific examples.
Answer:
Humans are less aggressive as compared to non-human primates.
Explanation:
Human affiliative and aggressive behaviors are different from nonhuman primates because humans do more friendly and peaceful acts and are less aggressive in anger as compared to non-human primates which are less friendly and more aggressive in anger. Due to more aggressive behaviour of non-human primates causes more damaged to other animals and humans as compared to humans who is less damaging and aggressive.

Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
What is his hypothesis?
a. Salt water freezes slower than fresh water.
b. Water freezes in a freezer
c. Salt water freezes faster than fresh water.
d. water will freeze in 20 minutes
salt water freezes slower than fresh water

You are in charge of genetically engineering a new organism that will derive all of its ATP from sunlight by photosynthesis. Will you put the enzymes of the citric acid cycle in this organism
Answer:
Yes.
Explanation:
I will put the enzymes of the citric acid cycle in this organism so that in the absence of sunlight, it also produces energy to grow quickly. Citric acid cycle is a series of chemical reactions which release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This cycle is also called Krebs cycle so incorporation of this cycle is good for the organism.
