Can you explain the relationship between EPSP, IPSP and action potentials?
Answer:
EPSP and IPSP trigger action potential
Explanation:
“EPSP” means “excitatory postsynaptic potential” which occurs when +ively charged ions move towards the postsynaptic cell thereby depolarizing of postsynaptic membrane potential. IPSPs are inhibitory postsynaptic potential. Whenever the EPSPs or IPSPs changes, the , neurotransmitters bind to receptors thereby opening or closing ion channels in the postsynaptic cell and hence triggering the Action potentials which is basically nerve impulses or spikes.

Question 3
Q: Which of the following is digested quickly in the body?
A. O Collagen
B. O Protein
c. O Monosacharide
D. O Unsaturated fat
Answer:
B. Protein
Explanation:
Protein is digested quickly in the body. Hence the correct option is A.
Define protein?A protein is defined as a naturally occurring, extremely complex substance which consists of amino acid residues fused by peptide bonds. Proteins are found in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.
Protein breakdown occur faster than fats and protein occurs mostly in the stomach, where stomach acids uncoil the protein strands. Pepsin, an enzyme secreted by the stomach, breaks the strands down further.
Trypsin, another enzyme, break down the protein strands into molecules containing one, two or three amino acids in the small intestine. Nearly all the protein in foods is digested, with the remaining passes through the large intestine.

describe what happens to nutrients and matter in a biogeochemical cycle
Answer: Nutrients move through the ecosystem in biogeochemical cycles. A biogeochemical cycle is a circuit/pathway by which a chemical element moves through the biotic and the abiotic factors of an ecosystem. It is inclusive of the biotic factors, or living organisms, rocks, air, water, and chemicals. Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled. The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.
Explanation:
Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.
Nutrients move through the ecosystem in the nutrient cycle or biogeochemical cycles. This cycle is a pathway by which a chemical element moves or recycles through the biotic and abiotic factors of an ecosystem.
It is inclusive of the biotic factors, or living organisms such as plants animals, and others, as well as abiotic or nonliving such as air, soil, and water.it moves through abiotic and biotic elements such as water moves through water body to the atmosphere by evaporation and moves back to earth and hydrosphere by rain and also used by living organisms.Thus, Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.

plants now, the amount of carbon dioxide in the atmosphere is decreasing." What is incorrect about
your friend's assessment?

1. Where is Earth’s water located? How much is freshwater?
2.What drives the watercycle?
3.Where are the world’s major oceans? Which ocean do we live closestto?
4.Why do we know relatively little about the bottom of the ocean? What does the ocean floor look like? (think: major features)
5.Why do we have ocean currents? How do currents affectclimate?
6.What causes ocean waves
Answer: 1. Water covers about 71% of the earth's surface. 97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling). 3% of the earth's water is fresh. Only about three percent of Earth's water is freshwater. Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground. Most of our drinking water comes from rivers and streams. Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground. 2.The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. ... The vapor rises into the air where cooler temperatures cause it to condense into clouds. 3. Historically, there are four named ocean basins: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean basin. The Pacific, Atlantic, and Indian are the most commonly known. Atlantic Ocean, body of salt water covering approximately one-fifth of Earth's surface and separating the continents of Europe and Africa to the east from those of North and South America to the west. 4. Marine creatures in shallower waters provide nutrients to deep-sea environments, as dead organisms “rain down” to the bottom. Fewer organisms in shallow waters means less food at the bottom. Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises. 5. Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. ... These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places. Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Some currents flow for short distances; others cross entire ocean basins and even circle the globe. By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. 6. Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. ... The gravitational pull of the sun and moon on the earth also causes waves. Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. This causes waves to form. brainliest??

Answer:
Large groups of the same type of cell, all working together for one purpose.
Explanation:
Human tissues are the group of cells that work together to perform a specific function. In tissues, similar type of cells combine together for performing similar function. The cells in tissue are same type means same size and structure. When a group of tissue combine together, it forms organ. These tissue can be broken down into simpler substances which are the cells that are considered as the basic unit of life.
in what ways do you think plants depend on soil ? based on your observations,can you imagine how soil might depend on plants or animals?In what ways do animals including humans depend on soil?
Answer:
Plants get nutrients from the soil. The soil also absorbs moisture, so the plant may also receive water from the soil. The plant also uses the soil as a way to support itself, using roots. Plants depend on animals for extra nutrition, as animals decay and become fertilization for the plants. Animals also drop feces, which can fertilize as well as spread the seeds. Humans depend on soil as a way to grow and cultivate plants.
