Answer:
Combustion.
Explanation:
It's just as it sounds, combustion is the process of burning something. In the carbon cycle, combustion occurs whenever any organic living or non-living thing is burned in the proximity of oxygen, afterwards producing carbon dioxide.
Combustion is the part of the carbon cycle which occurs when plants, trees, or fossil fuels are burned. Thus, the correct option is D.
What is Combustion?Combustion or burning is a high-temperature exothermic redox chemical reaction which occurs between a fuel and an oxidant. The oxidant is usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. This is one of the major reasons of pollution.
Three main types of combustion include rapid combustion, spontaneous combustion, and explosive combustion.
Therefore, the correct option is D.

Describe fully what will occur if a plant cell is placed in a solution that has a higher water potential than the cell. Use the following terms in your answer.cell wall, freely permeable, partially permeable, cell surface membrane, vacuole, tonoplast, cytoplasm, solute potential, pressure potential, water potential, turgid, osmosis, protoplast, equilibrium
Answer:
tortinos
Explanation:
hot pizza rolls
When the plant is placed in the higher water potential, the water will diffuse from the higher water potential to the lower water potential and make the plant cell turgid. As a result, the plant cell will swell.
What is the plant cell in a hypotonic solution?When a plant is placed in a hypotonic solution, that means the plant cell has less water potential than the outer side, and as a result, the water will flow from a higher water potential to a lower one. The plant cell membrane is partially permeable, and water will diffuse from the outer to the inner, causing the cell to exert more pressure on the cell wall and swell.
The vacuole will swell too in such a case, and the movement of water is called osmosis. The hypotonic solution has less solute potential, and the flow of water will continue until equilibrium is maintained.
Hence, this is the osmosis process, where the water will flow freely from the outside to the inside of the cell cytoplasm and make the cell turgid.

how could we decrease the amount of atmospheric CO2?
Atmospheric CO2 is an important trace element in the atmosphere. It is released into the atmosphere as a result of the combustion of fossil fuels and some other causes.
We can decrease the amount of atmospheric CO2 by growing more trees, using better alternatives in place of substances that leads to an increase in CO2.
More carbon dioxide is absorbed, lowering CO2 levels when we grow more trees as plants utilize this element a lot.Renewable energy sources like solar energy etc. to replace non-renewable sources can also be utilized.We can lessen our dependence on private mobility and use more of public mobility, or we walk / carpool instead.Learn more about atmospheric CO2: https://brainly.com/question/431949

1. How would you describe the biosphere?
2. What are some ways we, as humans, affect the biosphere?
Answer:
1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients
2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.
1. The human population is increasing by about 1.19 percent each year. Assume that the
population is 6.8 billion (6,800,000,000).
How large will the population be in one year?
The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.
Calculation of the population:Since the population is 6.8 billion or 6,800,000,000
And, the increase rate is 1.19% each year
So the population in one year should be
= 1.19% of 6.8 billion
= 8,092,000,000
hence, The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.

Answer:
hollow bird bones or option c
Explanation:

Hollow bird bones is not an example of an internal structure adaptation.
What is Internal structure adaptation?Any heritable characteristic that enables a plant or animal to survive and procreate in its environment is referred to as an adaptation. Individuals of a species can differ in a wide range of ways; some may be larger, hairier, better able to fend off illnesses, or even have smaller ears.
Their genes, which are inherited from their parents and later passed on to their own offspring, are mostly responsible for determining these traits.
The proportion of people who possess that favorable feature or adaptation will rise over generations until it becomes a characteristic shared by the entire species.
Therefore, Hollow bird bones is not an example of an internal structure adaptation.

The shadow zone exists due to the of seismic waves.
O A. reflection
O B. refraction
O C. absorption
OD. deletion
Answer:
B. refraction
Explanation: hope this helps!
The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.
What is Refraction?Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.
Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.
Therefore, the correct option will be B.

Answer:
They interact by the upper mantle transferring energy by conduction to the core assisting in the softening of the rock layer which leads to radiation.
Explanation:
Convection currents coming from the core and mantel are believed to the main cause of the interaction. As these currents travel up and down the curst and mantle boundary and this creates the plates to move freely forming a conveyor belt. The core of the earth creates this convective current to rise up due to the heat and pressure. The hot molten rocks in the mantle eventually cool and the cycle of rising and sinking takes place.In the graph below, which letter represents the activation energy of a catalyzed reaction and why?
