Describe the role of carbon in biological systems
Carbon is an important element that is necessary for the development and growth of the living organisms. It makes up the structure of living organisms.
Carbon having four valence electrons in it's outermost shell is able to bind with oxygen, nitrogen, and hydrogen to form biomolecules like carbohydrates, lipids, proteins, and nucleic acids. These biomolecules are involved in various processes in the living organisms like defense, reproduction, growth, photosynthesis, respiration, and others. These biomolecules are necessary for the proper functioning, growth, metabolism, and development of living organisms. Conclusion: Hence, carbon acts as an integral element that is necessary for structure and function of the organisms.Learn more about carbon:

How is the water movement on wetlands? Explain.
Answer:
Water is accommodated a wetland straightforwardly when precipitation falls on the wetland or by implication when precipitation falls outside the wetland and is shipped to the wetland by surface-or ground-water stream. For instance, snow that falls on wetland bowls gives surface-water stream to wetlands during spring snowmelt.
Answer:
Many pollutants are washed by rainfall from urban and agricultural lands and are carried overland to water bodies. Pollutants include soil particles, fertilizers, pesticides, grease and oil from cars and trucks, and road salts. Wetlands can improve water quality by removing pollutants from surface waters. Three pollutant removal processes provided by wetlands are particularly important: sediment trapping, nutrient removal and chemical detoxification.As water from a stream channel or surface runoff enters a wetland, the water spreads out and flows through dense vegetation. The velocity of the flow is reduced, allowing suspended material in the water to settle to the wetland surface. The roots of wetland plants can then bind the accumulated sediments. As much as 90 percent of the sediments that are present in runoff or in streamflow may be removed if the water passes through wetlands. Also, because pollutants, such as heavy metals, are attached to soil particles, the settling of sediments in wetlands further improves water quality.Nitrogen and phosphorus from agricultural and lawn fertilizers, pet waste, sewer and septic systems, and other sources can act as plant fertilizers in natural water bodies and stimulate excessive plant, algae, and cyanobacteria growth. Such growth may produce toxic chemicals and choke out natural vegetation and wildlife. When runoff and stream flow pass through wetlands before entering a water body, these nutrients may be taken up by wetland plants and accumulate in less harmful chemical forms. When wetland plants die and decay, nutrients are recycled within the wetland. Wetlands are so effective at removing excess nutrients from water that many municipalities have built wetlands specifically for treating effluent from secondary sewage treatment plants. Natural wetlands are not suited for this purpose and for each wetland there is a limit to how much can be added before the natural plant and chemical processes are overloaded and break down.

Which statement accurately describes the role of key organelles in energy transfer
Answer:
Energy is captured and stored in the chloroplast and released in the mitochondria.Explanation:
The statement that accurately describes the role of key organelles in energy transfer is Mitochondria.
The organelles are specialized structures present in the cells and they perform various functions to keep the cell alive.
Organelles perform particular functions to keep a cell alive in the same way that organs perform specific roles to keep an organism alive.
The organelles responsible for energy transfer in the cell are Mitochondria.
Mitochondria are organelles in cell that provide the majority of the chemical energy required to fuel the cell's metabolic processes.
The key role of mitochondria is energy transfer which occurs in Oxidative Phosphorylation. Oxidative Phosphorylation produces ATP (adenosine triphosphate) by employing the energy liberated during the oxidation of the food we consumed.
Therefore, we conclude that the statement that accurately describes the role of key organelles in energy transfer is Mitochondria.

What causes ocean water to be colder at the poles than at the equator?
A. Sunlight hits at an angle, so the warmth is spread out.
B. Sunlight hits directly, so the warmth is more concentrated.
C. Cold water currents move from the poles to the equator.
D. Seasonal winds push warm water away from the coasts.
The ocean water is colder at the poles than at the equator because
Cold water currents move from the poles to the equator.
What is an equator?
An equator a line imaginably drawn on the earth equidistant from the poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°.
The Equator is a circle of latitude, about 40,075 km in circumference, that divides Earth into the Northern and Southern hemispheres. In other words, The Equator is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles.
Locations on the equator experience the shortest sunrises and sunsets because the Sun's daily path is nearly perpendicular to the horizon for most of the year.
What are poles?Poles are the points where the earth’s imaginary axis of rotation intersects the earth’s surface and where the meridians converge.
The north pole is located in the northern hemisphere, in the central part of the Arctic Ocean. The south pole is located in the southern hemisphere, on the continent of Antarctica.
North and South poles are also defined for other planets or satellites in the Solar System, with a North pole being on the same side of the invariable plane as Earth's North pole.
Relative to Earth's surface, the geographic poles move by a few meters over periods of a few years. This is a combination of Chandler wobble, a free oscillation with a period of about 433 days; an annual motion responding to seasonal movements of air and water masses
Hence, option C is the correct answer
