Chemical energy from broken bonds is transformed into mechanical energy for muscles. The correct option is A.

What is chemical energy?

Chemical energy is the energy held in atom as well as molecule bonding.

Chemical energy can be located in things like batteries, biomass, oil, natural gas, and coal.

For instance, when humans burn wood in a fireplace or gasoline in a vehicle's engine, chemical energy is transformed into thermal energy.

Chemical energy, such as that held in the bonds of atoms and molecules, is stored energy. As a result of a chemical process, this energy is released.

Many chemical bonds throughout the body break during respiration, releasing energy. The movement of muscles is one activity that uses this energy.

Broken bonds' chemical energy is converted into mechanical energy for muscles.

Thus, the correct option is A.

Maxine miles runs a marathon in 2 hours and 40 minutes. most of the atp for this activity is supplied by:

Answers

Maxine miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by AEROBIC glucose breakdown. ATP is the energy coin of the cell.

Cellular respiration refers to the metabolic processes by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods (e.g., glucose) and oxygen.

Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).

Acid lactic fermentation is a less efficient pathway than cellular respiration, but cellular respiration is slower than fermentation, thereby muscle cells use this pathway (acid lactic fermentation) when there is not enough oxygen in the body.

Which of these solutions is the best way to help a city as its population grows
and its air becomes more polluted?
O A. Invest in urban sprawl to better disperse the pollution.
OB. Invest in alternative energy sources to reduce emissions.
O C. Reduce road construction to dissuade new residents.
O D. Reduce air-quality regulations so businesses can grow unimpeded.

Answers

Answer:

B. Invest in alternative energy sources to reduce emissions.

Explanation:

The best way to help a city as its population grows, and its air becomes more polluted, is to invest in alternative energy sources to reduce emissions. The correct option is B.

What is pollution?

Pollutants are the name for these dangerous substances. Natural pollutants include volcanic ash, for example. They can also be brought by human activities, such as factory runoff or waste.

Air pollution is caused by solid, liquid, and gaseous pollutants. These gases and particles can be produced by factories, volcanoes, wildfires, dust, pollen, and vehicle and truck emissions.

To stop pollution, we must use alternative energies that do not cause pollution.

Thus, the correct option is B. Invest in alternative energy sources to reduce emissions.

Would a plant be able to survive if the ground tissue was damaged? Explain your answer.

Answers

Given what we know, we can confirm that with damaged ground tissue, a plant will most likely not be able to survive.

What we know about ground tissues in plants.The ground tissue forms an abundant part of all plant tissues. This tissue includes all plant tissue that is neither vascular nor dermal.This means that ground tissue covers a wide variety of functions. Two primary and important functions are the storage of sugar and water.

Therefore, given the vital role of this tissue in plants and its function in storing "food" and water, we can confidently say that a plant with damaged ground tissue will not be able to survive for long.

place each of the labels in the proper position to denote whether they would pass through the filtration membrane or not.

Answers

The labels that will pass through the filtration membrane are water, glucose, and sodium.

The labels that will not pass through the filtration membrane are red blood cells, lymphocytes, antibodies, and platelets.

The filtration membrane is a microporous glomerular barrier membrane made of polymeric materials that are used for the separation and filtration of substances based on their molecular weight.

Depending on the molecular size of a substance situated in the blood, we can determine if such substances can be filtered through the filtration membrane or not.

However, the lower the molecular weight of the substance, the higher their likelihood of filtration.

In the plasma, the substance that has a lower molecular weight are water, glucose, and sodium while substance associated with protein, blood cell, and platelets contains higher molecular weight.

A population of beetles is mostly composed of individuals with the dominant green color, but there are several with the recessive brown
color. A displaced species of bird moves into the habitat and preferentially preys upon the green beetles. Over time, what can be expected
to happen to the beetle population?
O A. The beetles will migrate to avoid being eaten by the birds in the habitat.
OB. The beetle population will become extinct.
O C. The beetle population will stabilize because the birds will not eat more beetles than necessary to maintain ecological balance.
O D. The brown beetles will become more common.

Answers

The green beetles will decrease in number while the brown beetles will become more common.

According to Darwin's theory of evolution, organisms that are better adapted to their environment are able to live longer and survive long enough to reproduce thereby perpetuating their favorable characteristics in the population.

Since the green beetles are more common but they are preferentially preyed upon by the invasive bird species, the green beetles will decrease in number while the brown beetles will become more common.

combine with each other using covalent bonds

Explanation:

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

Answer:

Dehydration synthesis is a process by which two monomers are linked to form a polymer, with water being given off as a byproduct.  Conversely, hydrolysis is the process by which water is introduced in order to break down a polymer into its monomer building blocks.
