Which statement about cellular respiration is true?
O It produces oxygen,
It requires water.
It is used by every living cell.
It converts energy to food.

Answers

Answer:

It is used by every living thing.

Explanation:

This would be correct because all living things use cellular respiration.

Cellular respiration does not produce oxygen in all cases. In animals and humans, cellular respiraction actually produces carbon dioxide. It definitely does not convert energy to food and it does not necessarily require water to be performed.

Where are coral reefs most threatened by pollution, and what effects has pollution had so far?

Answers

Answer:

In the great barrier reef

Explanation:

It has effected plants and sea creature populations because of their homes being destroyed

Coral reefs are most threatened by pollution, as they are becoming extinct due to air pollution, water pollution, etc., and then human interference again lets them go extinct, and these reefs that are present in the site of the population are lost mostly.

What is the significance of the coral reefs' extinctions?

Coral reefs are negatively affected by pollution and human activities, which include coral bleaching; and again, climate change that is caused by human activities such as the burning of fossil fuels, etc. induces the coral bleaching. Different chemicals that mix with water destroy the corals and the algae present in them.

Hence, coral reefs are most threatened by pollution, as they are becoming extinct due to air pollution, water pollution, etc., and then human interference again lets them go extinct, and these reefs that are present in the site of the population are lost mostly.

Why is there less air pressure at higher altitude?
A: Air at higher altitudes doesn't have as much air weighing down on it from above.

B: Air at higher altitudes is cooler and less turbulent.

C: The warmer, lighter air rises bringing cooler heaver air to low altitudes.

D: The molecules in the air lose mass and are less effected by gravity, significantly lowering their weight.

Answers

I believe D is the answer to the question
Hope this helps you have a good night

There less air pressure at higher altitude because the molecules in the air lose mass and are less effected by gravity, significantly lowering their weight. Thus, option D is correct.

What is the mass percent?

Mass percent is the mass of the element divided by the mass of the compound or solute.

Step 1: Calculate the mass of the compound.

mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu

Step 2: Calculate the mass of hydrogen in the compound.

mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu

Step 3: Calculate the mass percent of hydrogen in the compound.

%H = (mH in mCH₄O / mCH₄O) × 100%

%H = 4.00 amu / 32.01 amu × 100% = 12.5%

The mass percent of hydrogen in CH₄O is 12.5%.

CO2 = 1.580 grams H2O = 0.592 grams Lookup the molar mass of each element in the compound Carbon = 12.0107 Hydrogen = 1.00794 Oxygen = 15.999 Calculate the molar mass of CH4O by adding the total masses of each element used. 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now calculate how many moles of CH4O you have by dividing by the molar mass.

Therefore, There less air pressure at higher altitude because the molecules in the air lose mass and are less effected by gravity, significantly lowering their weight. Thus, option D is correct.

ii) What kind of selection has taken place? (1)

Answers

i) Because the worms would have either learned to become night worms or all day worms would have been eaten faster than they could reproduce

ii) Natural selection. Humans had no interaction with which worms survived, so it's all natural.

What is a fossil?

A fossil refers to the mineral impression or remains of both living and non-living organisms that are generally considered to be prehistoric in nature.

This ultimately implies that, fossils are obtained from ancient organisms such as H-o-m-o Erectus, which is an organism that could walk on two (2) feet like humans.

However, amber-preserved fossils are  actually very helpful in studying organisms that are generally considered to be prehistoric in nature.

Explain how heat can be a source of water pollution.

Answers

Answer:

Decreases amount of available oxygen in water causing some fish to decay because of the lack of oxygen.

Explanation:

Heat boosts fish metabolism and lowers water's ability to hold dissolved oxygen, making it a water pollutant. Low-dissolved oxygen water kills game fish like trout.

Why is heat a source of water pollution?

The ability of water to keep dissolved oxygen in solution is reduced when heat is present, and fish have a faster metabolic rate when heat is present. For these reasons, heat is regarded to be a pollutant in water. In waters with exceptionally low concentrations of dissolved oxygen, game fish such as trout and other valuable species simply are unable to live.

The release of warm water into existing bodies of water is referred to as thermal pollution. Thermal or nuclear power plants, industrial effluents such as petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters, and sewage effluents, as well as biochemical activity, are the primary contributors to thermal heat pollution. Other contributors include biochemical activity.

Which human activity is correctly paired with the greenhouse gas that it increases?
rice cultivation and water vapor
landfilling and carbon dioxide
deforestation and methane
sewage treatment and nitrous oxide

Answers

Answer:

land filling and carbon dioxide

Explanation:

landfilling and carbon dioxide human activity is correctly paired with the greenhouse gas that it increases.

What is Landfilling?

The emission of methane gas from landfills is the primary environmental issue. Methane gas is generated during the breakdown of organic material in landfills.

Methane is one of the most potent greenhouse gases and a major cause of climate change since it is 84 times more efficient than carbon dioxide at absorbing heat from the sun.

In addition to methane, landfills also release water vapour, carbon dioxide, and small amounts of oxygen, nitrogen, and other non-methane organic molecules. If not under control, these gases can also contribute to climate change and lead to pollution.  

Therefore, landfilling and carbon dioxide human activity is correctly paired with the greenhouse gas that it increases.

Then during Stage 2, improvements in health care, sanitation, and nutrition all people to live longer and reduce the death rate. The birthrate however, remains high during this stage so the population increases rapidly. This occurred in the US in the 1800s. Eventually, birthrate decreases to match the low death rate and the population growth slows and eventually stops. This is the US today.

Answers

Explanation:

it is systematic desensitization.

Creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

Systematic desensitization is a type of therapy based on the combination of relaxation methods with gradual exposure to the fear (phobia).

The objective of the exposure to the fear is that the patient feels progressively less anxious about his/her phobia.

In consequence, systematic desensitization increases the feeling of self-control and gradually reduces fear.

In conclusion, creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.
