А.
water photosynthesis
B
sugar respiration
С
sugar photosynthesis
D
water respiration
The mechanism by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as Photosynthesis.
What steps are involved in a plant's photosynthesis?Green plants and various other organisms convert light into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change waters, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
What makes photosynthesis so crucial?The significance of photosynthesis Solar or radiant energy is converted into chemical energy during photosynthesis. The production of agricultural crops is directly impacted by the rate of photosynthesis. All living things require oxygen, which it provides for the atmosphere. It keeps the ecosystem's carbon dioxide and oxygen levels in check.

Which cell has the GREATEST surface area to volume ratio?
O Chicken egg
O Skin cell
O Bacterial cell
O Liver cell
The cell with the greatest surface area to volume ratio is the smallest cell, in this case, the bacterial cell.
As a cell increases in size, the proportional increase in volume is higher than that of its surface area. This tells us that the bigger a cell becomes, the lower its surface area to volume ratio will be.
The chicken egg is just one large cell, the largest cell produced by most animals. The skin and liver cells are much smaller, measuring roughly 25-30 micrometers. However, the smallest of the list by far is the bacterial cell, measuring a mere 1-3 microns. This size tells us that the greatest surface area to volume ratio belongs to the bacterial cell.

What term describes the strings of ribosomes that are attached to an RNA transcript at one time?
A. release factors
B. spliceosomes
C. transcription factors
D. mutagens
E. polyribosomes
Answer:
Polyribosomes.
Explanation:
During translation, the subunits of a ribosome surround the transcript and read down stream until they reach the start codon and begin polypeptide synthesis. Once the start codon is exposed, it is available for another ribosome to form around it, thereby initiating another locale for translation. Together the strings of ribosomes are called polyribosomes.
What property of water allows water
to soak up so much CO2 gas?
Answer:Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn't escape the ocean easily. As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance.
Explanation:

Answer:
Inflammation
Explanation:
Innate Response:
"The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system. It acts very quickly: For instance, it makes sure that bacteria that have entered the skin through a small wound are detected and destroyed on the spot within a few hours. The innate immune system has only limited power to stop germs from spreading, though. The innate immune system consists of: Protection offered by the skin and mucous membranes AND Protection offered by the immune system cells (defense cells) and proteins."
Acquired Response:
"The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection. But to do that it first needs to identify the germ. This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster. The adaptive immune system is made up of: T lymphocytes in the tissue between the body's cells AND B lymphocytes, also found in the tissue between the body's cells AND Antibodies in the blood and other bodily fluids."
I'm sure it's Inflammation, so here is the definition for that:
"Inflammation refers to your body's process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system."

C. in areas with different air pressures
D. in areas with different cloud types.
Answer:
the answer is C-in areas with different air pressures
Explanation:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.
Answer:C. in areas with different air pressures
