osmosis
Explanation:
on edge2020
The movement of water from an area of high water concentration to an area of low water concentration is called as Osmosis. Thus option D is correct.
What is osmosis ?The process in which solvent molecules pass from a lower concentration based solution to a higher concentration solution through a semipermeable membrane called as osmosis.
It is a passive process as no external energy is needed.
When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as ex-osmosis.
The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.
When the plasmolysed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.
This condition is called deplasmolysis or cytolysis. Thus option D is correct.

Whats is a difference between prokaryotic and eukaryotic cells?
Answer:
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis.
Explanation:
Because the bodies of animals contain carbon molecules, the animal kingdom stores huge amounts of carbon. Which of the following processes returns carbon from this vast reservoir to the active carbon cycle?
Answer:
burning fossil fuels and decomposition of dead organisms
Explanation:
A significant amount of the carbon in the biosphere is returned to the carbon cycle through decomposition by fungi and bacteria. Much of what is not decomposed becomes fossil fuels. When humans burn fossil fuels for energy, carbon is returned to the atmosphere.
The process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A, as when an animal dies, its body is broken down by decomposers, such as bacteria and fungi.
What is decomposition?The decomposition process is essential for the cycling of carbon in the environment. When an animal dies, the organic molecules that make up its body become available to decomposers. These decomposers use enzymes to break down the complex organic molecules into simpler compounds, such as sugars, amino acids, and fatty acids.
Hence, the process that returns carbon from the vast reservoir of animal bodies to the active carbon cycle is called decomposition, which is present in Option A.

body temperature rises, how
does your body maintain
homeostasis? What are some
things that happen? How do you
cool off? What happens to your
breathing? Blood flow?
Answer:
During exercising, your body's temperature levels up and one of the body's mechanisms of homeostasis is perspiration, which is sweating. Sweat helps cool off the body by excreting the heat to the exterior surface f the body and it gets rid of excess fluids and salts. The breathing rate also gets higher due to the physical activity. Blood flow will increase as well, as the blood vessels dilate and get wider allowing more blood to pass through.

Can someone please give me An example of an ionic bond with a positive ion and negative ion
Answer:
NaCl
Explanation:
ionic bond is the bond results from the electro static force of attraction between oppositely charged ions in other words its the linkage formed by the transfer of one or more electron from one atom to another atom
Na gives it electron to chlroine so Na becomes positively charged and Cl becomes negatively charged and they attract each other to form ionic bond
Na is positive Cl is negative
Suggest why a cell within the trunk of a tree cannot carry out photosynthesis.
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.
Explanation:
The trunk of a tree consists of dead tissues and serves only to support the weight of the tree crown. This portion of the tree does not contain chloroplast, hence photosynthesis is not carried.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The part of the trunk region of the tree does not have chloroplast, chlorophyll pigments, and other required machinery which is significantly utilized by the leaves of the tree in order to perform photosynthesis. Due to this, the trunk part of the trees is not capable to carry out the same process.
Therefore, the most prominent reason why a cell within the trunk of a tree cannot carry out photosynthesis is well described above.

1)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
2)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
Answer/Explanation:
1) When phosphate is transferred from ATP, (which forms ADP and releases energy) it can phosphorylate another molecule. When this molecule is phosphorylated. It could become "energized" as it enters a higher energy state.
In this higher energy state, the protein has the energy to transfer molecules against a concentration gradient, which is an active process (requires energy).
2) Adenosine triphosphate contains three phosphate groups. The phosphate bonds are high energy. When ATP is hydrolyzed (water is added), these high energy phosphate bonds are broken and energy is released. This forms adenosine diphosphate (ADP).
1) When a protein molecule is phosphorylated, it becomes activated or powered and enables it transport molecules against their concentration gradient.
2) The bond that holds phosphate bonds in ATP gives it the ability to act as an energy currency.
ADENOSINE TRIPHOSPHATE (ATP)
Adenosine triphosphate, commonly known as ATP, is the means by which energy is stored and released in the cells of biological organisms. ATP is structurally made up of a ribose sugar, an Adenine base and three phosphate groups. The phosphate groups are held together by a bond called phosphoanhydride bond. ATP stores energy when one phosphate molecule is added to ADP while it releases energy when one phosphate group is broken. This latter process is called PHOSPHORYLATION. The ability of ATP to lose and accept phosphate group in its structure makes it perform the role of an energy currency in the cell.However, when a phosphate group is added to a molecule e.g. a transport protein, it is said to be phosphorylated. This means it will become activated or powered up to perform the task of transporting molecules against their concentration gradient.Learn more: https://brainly.com/question/15585148?referrer=searchResults
Which situation is a good example of the transfer of energy through radiation?
A. Energy passes from one person’s hand to another person when they shake hands.
B. A snake’s body temperature increases when the snake lies in the Sun.
C. Warm air that is less dense rises to the ceiling of a room.
D. A fan cools the CPU in a computer.
Radiation has been the mode of thermal energy transfer from a source. "A snake’s body temperature increases when the snake lies in the Sun" is an example of radiation. Thus, option B is correct.
What is radiation?Radiation has been the type by which the thermal heat energy passes from the source to the other site. It has been independent of contact and involves traveling in space with the equivalent speed of light. Unlike conduction and convection, radiation does not need matter.
The particles tend to move in space like the sun's rays heating the earth. When a snake lies in the sun its body temperature rises due to tradition as the solar energy from the sun (high temperature) moved in space to the lower temperature (snake's body).
Therefore, option B. heating the snake's body under the sun is an example of radiation.

Which statement provides a conclusion about the transport of water in and out of cells based on the results of the student's experiment? A. Water moves freely both inside and outside the cell independent of the solute concentration. B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell. C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell. D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.
Answer:
B.
Explanation:
The transport of water in and out of cells based on the percent concentration of solutes both inside and outside the cell.
The movement of water in and out of the cell is called osmosis. In the process of osmosis, water or solvent moves from low to high concentration of solute (towards high solute concentration). For example, if a cell is placed in a salt (solute) solution, the water will move out of the cell or towards high salt concentration and the cell will get shrink.
Hence, the correct answer is "B."

Explanation:
What is a small ecosystem in danger of compared to a large and diverse ecosystem?
Answer:
See the answer below
Explanation:
A small ecosystem is in danger when compared to a large and diverse ecosystem because the genetic variability in a small ecosystem is low and a small disruption can wipe out the populations within the ecosystem. This is unlike in a large ecosystem where this is a high genetic variability that gives the populations within the ecosystem resilience against disturbances.
There are enough alleles within the genetic pool of a large and diverse ecosystem to withstand disturbance regimes unlike in small ecosystems where the alleles are few. Hence, a little disturbance can endanger the entire population in a small ecosystem and put them at the risks of extinction.
