Which is a reactant in the Calvin cycle?
A. Glucose
B. Oxygen
C. Carbon dioxide
D. Water
The reactant of the Calvin cycle is the carbon dioxide that is present in Option C, and the product of the Calvin cycle is glucose. The Calvin cycle takes place during the photosynthetic reaction.
What is the role of photosynthesis?Photosynthesis is a process in which the plant plays an important role, such as when the plant absorbs the sun's light, water, and carbon dioxide and then produces oxygen and glucose by combining all of these elements; thus, glucose and oxygen are the products, and water and carbon dioxide are the reactants. The water is used in the light-dependent reaction and converted into oxygen as a product, while in the case of the Calvin cycle or the light-independent reaction, carbon dioxide is used as the reactant and the product that is formed is glucose.
Hence, the reactant of the Calvin cycle is the carbon dioxide that is present in Option C.

HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.
The researchers predicted that for any particular concentration of substrate, the C. Aurantiacus enolase catalyzedreaction is more rapid at 55 C. Than at 37 C. Provide reasoning to justify the researchers prediction.
Answer:
It's justified because an increase in temperature will lead to increase in the enzyme catalyzed reaction
Explanation:
Now, as the temperature is increasing, the kinetic energy of molecules will also be increasing and this implies that the collision between the substrate and enzyme will increase i.e substrate that's attached to its appropriate active site of enzyme that results in an increase in reaction.
However, if the temperature is too high, it can cause the enzymatic activity to denature.
In summary, when talking about catalyzed reactions, an increase in temperature will cause the bond between molecules to loosen and this results in catalyzation.

beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.
If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.
Requires the use of energy to molecules.

Michaela spend the day at the lake with some friends. She spends some time exploring the lake as she looks around she notices that there are plants only in certain areas where would she see plants growing? Why?
Answer:
She would mostly see plants grow around the banks of the lake. In addition, she might see some plants growing in the lake. The plants are majorly aquatic plants. The ones on the banks are emergent plants because their roots are submerged in water and their foliage is above water. They grow on the shores because it shallow there. Free-floating aquatic plants may grow in the lake because they are suspended on the water surface with their roots just floating underneath the water surface.

Hydrogen peroxide naturally breaks down into oxygen and water over time. When exposed to the enzyme catalase, hydrogen peroxide is rapidly converted into oxygen and water.
What feature of catalase most likely is responsible for the change in the rate of conversion of hydrogen peroxide into water and oxygen?
A, Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy.
B, Catalase bonds permanently with the reactants causing hydrogen peroxide to rapidly break down by increasing the activation energy.
C ,Catalase has a flexible structure that allows it to bind and convert any small hydrogen containing compound into water and oxygen.
D, Catalase remains intact, so small amounts of it convert large amounts of hydrogen peroxide into water and oxygen immediately.
Answer:
Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Completely disinfect any surface that the raw liver touches during this activit.
Explanation:

Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.
