An ocean pH change from 8.2 to 8.0 is NOT significant as the .2 change is very small.
So far, the ocean's pH has dropped from about 8.2 in preindustrial times to around 8.05. This seemingly small change may already be affecting ocean organisms and future CO2 emissions could lower ocean pH even further

How does diffusion occur without any Energy?
Answer:
it moves from a stronger region of concentration to a weaker region of concentration so therefore does not call for or require energy
Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform various activities such as moving muscles.
Explain the energy transformation in this process.
A. Chemical energy from broken bonds is transformed into mechanical energy for muscles.
B. Mechanical energy from broken bonds is transformed into chemical energy for muscles.
C. Mechanical energy from broken bonds is transformed into electrical energy for muscles.
D. Heat energy from broken bonds is transformed into electrical energy for muscles.
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.

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.
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.

Explain the relationships between dehydration synthesis, hydrolysis, monomer, and polymer
Answer:
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.

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

the small bones in the middle ear that transmit vibrations to the inner ear
Answer:
, yes..............
Explanation:
because the vibrations are transmitted to the inner ear after the bones amplify it
Ossicles are the body's tiniest bones. the malleus (hammer), incus (anvil), and stapes (stirrup). Ossicles amplify sound.
What are ossicles?Ossicles are very little bones; in fact, they are the tiniest bones in the entire human body. The malleus (hammer), the incus (anvil), and the stapes are the names of the three bones because of the forms they make (stirrup). The sound is amplified even further by the ossicles.
In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
Hearing is dependent on a series of intricate steps that convert sound waves in the air into electrical impulses. These steps are necessary for hearing.
