Answer:
Either carbon got here by diffusing from the atmosphere, by decomposing marine life, or from circulating water from the deep ocean.
The ocean absorbs more carbon dioxide from the atmosphere than the land does.
The surface ocean takes in approximately 90 Gigatons of carbon per year.

1. What do you know about gravity?
2. How could gravity affect the water cycle?
Explain your answer.''
Explanation:
What do you know about gravity?
ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
How could gravity affect the water cycle?
ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Without diabetes, insulin produced in the pancreas on islets of Langerhans by beta cells to regulate blood sugar levels. Type 1 diabetes occurs when the pancreas produces little to no insulin.
In a flock of birds, parents can raise small clutches on their own but can increase their clutch size if they have a helper. You want to see if altruistic behavior is likely to spread. To do this you observed a male bird that stayed at his birth nest for a year to help raise the offspring of his father and his stepmother (the original mother died) and then built his own nest the following year. You calculated direct fitness (cost) for the male bird by counting the number of offspring he produced in one year and multiplied it by ½ due to the relatedness between parents and offspring. To calculate his indirect fitness (benefit), you took the total number of offspring produced in his birth nest by his father and stepmother when he assisted them and multiplied it by ½. To determine if this altruistic behavior would spread you subtracted the cost from the benefit to determine whether it was greater than 1. What did you do wrong
Answer:
The mistakes made
Altruistic behavior is measured as ; b - c > 0 and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2Explanation:
The relatedness between ; Mother, father, daughter and son = 0.5 ( 1/2 ) which is included in the direct fitness category ( For the MALE bird )
The relatedness for the Half brother and Half sister of the male bird = 0.25 ( 1/4 ) ( indirect fitness )
hence applying Hamilton's rule
Relatedness = rb - c > 0
where b = benefit , c = cost
∴Total fitness = ∑ direct fitness + ∑ indirect fitness
= 0.5x + 0.25y
hence the mistakes made
Altruistic behavior is measured as ; b - c > 0 and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2What basic substances make up a cell
Answer:
The main ingredient of cells is water. Water is needed to maintain homeostasis. Cells are also made up of macromolecules—nucleic acids, lipids, proteins, carbohydrates. These macromolecules help maintain a cell's structure, help cells communicate with each other, aid in energy storage, etc.

Water
Explanation:
Fibroblasts can be placed on thin sheets of silicone rubber. Under normal circumstances, fibroblasts exert sufficient tension on the rubber so that it visibly wrinkles. Explain how the ability of fibroblasts to wrinkle rubber would change if the cells were treated with a permeable form of C3 transferase, a toxin (from the bacterium Clostridium botulinum) that covalently modifies an amino acid in Rho. The modification renders Rho unable to bind to proteins that it would normally bind to when active.
Answer:
C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles
Explanation:
Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.

Increasing sea surface temperatures should...
Lower the amount of dissolved oxygen in the ocean, depriving many
invertebrate animals of oxygen necessary to live.
Lower the amount of sea ice in polar areas. This will warm the water,
decreasing the abundance of primary producers and the number of
organisms that eat these producers.
Increase the temperature difference between the upper and lower parts of
the ocean, making upwelling less likely to occur. This will decrease ocean
nutrient levels, affecting the number of primary producers.
Raise water temperatures above the tolerance limits for many aquatic
organisms in tropical areas, increasing stress on these species.

Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s ________.
A. gravitational pull
B. eye
C. updraft
D. fog
Plz Help!!! God Bless You
Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s updraft.
What do you mean by updraft?Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over the hill. Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals.
The definition of an updraft is a strong upward current of air. When a big gust wind comes along and catches on the umbrella on your outside table from underneath, knocking your umbrella and table over with its power, this big gust of wind is an example of an updraft.
When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water droplets as it rises. The cloud will continue to grow as long as warm air from below continues to rise.

Ultrafine particles cause poor health.
Nose hairs and mucus catch all the particles before they reach the lungs
Ultrafine particles are absorbed by the lungs when people breathe.
Ultrafine particles contribute to more than 20,000 deaths per year in the United States.
Most ultrafine particles can be seen with the unaided eye.
Answer:
A and C
Explanation:
The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs. So, the correct options are A and C.
What are Indoor pollution?Indoor air pollution, which can be as much as ten times worse than outside air pollution, is indeed the degradation in indoor air quality caused by hazardous chemicals and other elements. This is because enclosed rooms encourage the accumulation of possible contaminants more than do open ones.
The main contributors to indoor air pollution include: Bioaerosols, building materials, and combustion Although radon, asbestos, pesticides, toxic substances, organic volatile compounds, and environmental tobacco smoke are all regarded as serious indoor pollutants in industrialised countries, developing countries are primarily affected by the combustion byproducts of biomass fuels.
The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs.
Therefore, the correct options are A and C.

All plants are subject to photorespiration, but not all plants are equally affected by photorespiration due to the environment in which they live.Choose one of the two pictures (A or B) and explain why that environment would increase the likelihood that those plants would be greatly affected by photorespiration. Your answer should describe the nature of the environmental impact and how the impact would affect the anatomy and physiology of photosynthesis of the plant.The environments are:A. Desert. Prairie
Answer:
Desert.
Explanation:
Photorespiration occurs in C3 plants because their photosynthetic activities are disturbed due to high temperature of the environmental while on the other hand, C4 plants has absent this photorespiration process. The desert environment has direct impact on the plants having photorespiration due to its high temperature of the surrounding as compared Prairie where the environment is moderate so the C3 plants has high chances of photorespiration in desert condition as compared to Prairie.
