Plants and Animals maintain a balance of CO2. Plants take in CO2 by photosynthesis and animals release CO2 by respiration.
When a cell has energy available, how can it store small amounts of that energy?
Answer:
When a cell has energy available, it can store small amounts of it by adding phosphate groups to ADP, producing ATP. ADP is like a rechargeable battery that powers the machinery of the cell. One way cells use the energy provided by ATP is to carry out active transport.

Who are the key players in dna replication
The key players in DNA replication are enzymes. These enzymes are helicase, primase, DNA polymerase, and ligase.
What is the role of enzymes in DNA replication?At the replication fork, the enzymes responsible for DNA replication work in concert to simultaneously synthesize the DNA's leading and lagging strands. The replication DNA polymerases (Polymerase III in E. coli) produce dimers to complete this activity.
The enzyme DNA polymerase, also referred to as DNA pol, is one of the main players. DNA pol I, DNA pol II, and DNA pol III are the three primary forms of DNA polymerases found in bacteria.
DNA pol III is currently understood to be the enzyme needed for DNA synthesis, whereas DNA pol I and DNA pol II are mostly needed for repair.
Therefore, the key players in DNA replication are enzymes. These enzymes are helicase, primase, DNA polymerase, and ligase.

how are Metamorphic rocks with fine grains made and how did the composition of the Earth’s atmosphere cause changes to form the rock over time.
Answer:
A rock is a naturally formed, non-living Earth material. Rocks are made of minerals. ... A rock may be made of only one type of mineral. More often rocks are made of a mixture of different minerals.
Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Metamorphism also happens when rocks are buried deeply during the process of mountain building. The kind of metamorphic rock made depends on the kind of original rock; for example, sandstone is turned to quartzite, shale is turned to slate, and limestone is turned to marble.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Can hydrogen peroxide be broken down by catalysts other than those found in a living system? What is/are the control(s) and why are they needed?
Answer:
Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. It is unstable which makes it very reactive. ... Sand however is not able to break it down
Explanation:
because it contains no catalytic properties
Manganese dioxide, which has catalytic properties, can degrade hydrogen peroxide. Because it is unstable, it is extremely reactive. It even degrades when exposed to light.
What is a catalyst?A catalyst is a substance that accelerates or reduces the temperature or pressure required to initiate a chemical reaction without being consumed in the process. Catalysis is the process of facilitating a reaction by adding a catalyst.
Hydrogen peroxide is one of the cleanest and most versatile chemicals available, decomposing to produce only oxygen and water (disproportionation).
The catalytic decomposition of hydrogen peroxide allows for the use of various catalysts to speed up the decomposition process.
Another consideration is that catalase is an enzyme that degrades at higher temperatures. The activation energy of the reaction changes as the catalyst decomposes.
As a result, the reaction will slow down. Manganese dioxide, on the other hand, does not decompose even at higher temperatures.
Thus, it can be concluded that hydrogen peroxide be broken down by catalysts other than those found in a living system.

where does the energy for active transport come from
Answer:
Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. Energy for the process is acquired from the breakdown of glucose using oxygen in aerobic respiration. ATP is produced during respiration and releases the energy for active transport.

a) Carbon monoxide (CO) is being released by natural systems. Oceans are absorbing this excess of CO and the pH within the oceans is increasing.
b) Methane (CH4 is being released too quickly from burning of fossil fuels. Oceans are lowering their pH and ocean acidification occurs.
c) Natural sources are releasing an excess of CO2 to the oceans. The marine photosynthetic organisms are emitting too much oxygen. This is return is causing ocean acidification.
d) The excess of CO2 emitted from anthropogenic sources is being absorbed by the oceans from the atmosphere. This results in more hydrogen ions in the ocean, which increases acidification.

Answer:
I am not sure what you are asking but when pH is alkaline it will change the litmus paper to that blue color.
What process is taking place in the image below?
You can see in this particular structure, there is a hydrogen bond between a hydrogen on the hydronium ion and the oxygen on the other water molecule.
Hydronium ions don’t exist in on their own, they’re required to have some way of balancing the charge that comes from the additional hydrogen ion. This balancing is typically done by the water surrounding the hydronium ion (H3O+H3O+) since water will outnumber the amount of hydronium atoms by orders of magnitude (there’s a lot more water than ions).
The hydronium ion in cold water is typically surrounded by 6 water molecules (probably oxygen towards the extra hydrogen but I can’t access the journal to confirm). There are some other structures like the one above, and another called the Eigen cation where the hydrogen is at the center of four water molecules (one is technically the hydronium). There’s also a very large structure that’s called the magic structure that has a hydronium ion surrounded by twenty water molecules (it’s called magic because it’s extra stable for its size).
