O biosphere
O atmosphere
Answers
The part of the environment that incorporates carbon into the carbon cycle via water is the hydrosphere, which is present in the second option as in the hydrosphere water bodies are present, such as the ocean, etc.
What is the significance of the hydrosphere?On the earth, there are geospheres where the mountains and hills are present, and there are hydrosphere where the water bodies are present, and this hydrosphere is important because it is important for maintaining the carbon cycle. Carbon dioxide is exchanged between the atmosphere and the hydrosphere through processes such as photosynthesis and respiration that are carried out by plants and animals and these carbons is dissolved in water bodies.
Hence, part of the environment that incorporates carbon into the carbon cycle via water is the hydrosphere, which is present in the second option as in the hydrosphere water bodies are present, such as the ocean, etc.

b. Photosynthesis uses light energy to convert glucose and carbon dioxide to oxygen and water.
c. Photosynthesis uses light energy to convert carbon dioxide and oxygen to glucose and water.
d. Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.
Answers
Answer:- D
Photosynthesis used light energy to convert carbon dioxide and water into glucose and oxygen
The statement that best describes photosynthesis is statement d. As it converts carbon dioxide to glucose and oxygen.
Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.During photosynthesis, plants, algae, and some bacteria convert light energy into chemical energy, stored in the bonds of glucose molecules.
The process involves the absorption of light by pigments called chlorophyll, which are present in the chloroplasts of plant cells and other photosynthetic organisms. Chlorophyll uses the light energy to drive the conversion of carbon dioxide and water into glucose and oxygen in a process called the Calvin cycle.
Thus, the correct option is statement D.

ANSWER ASAP PLEASE. What process occurs after glycolysis if oxygen is still available for cellular respiration?
Answers
Glycolysis is the process of breaking glucose into energy. If oxygen is still available for cellular respiration after glycolysis then, the Krebs cycle and oxidative phosphorylation will occur.
What is Kreb's cycle?Kreb's cycle (TCA) is the important cycle in aerobic organisms that produce energy from acetyl CoA into NADH, ATP, and FADH₂ through the proteins, carbohydrates, and fats.
In oxidative phosphorylation, the ATP synthesis is connected to the ETC and along with the citric acid, the cycle produces more energy in the form of ATP in the presence of oxygen.
Therefore, the Kreb cycle and oxidative phosphorylation occur if oxygen is still available after the process of glycolysis.

Viscosity is a measure of a fluid's resistance to
flow
A: True
B: False
Answers
Answer:
Viscosity is a measure of a fluid's resistence to flow is true i believe
Viscosity is a measure of fluids' resistance to flow a correct statement. So the correct option is True.
What is viscosity?The measurement of a fluid's resistance to its own flow and any objects that may be inserted in it is called viscosity.
Viscosity is given by the symbol η (eta) and is defined as the ratio of shearing stress (F/A) and the velocity gradient of the flow of a liquid (dvx/ dy).
Velocity is also defined in the form of Newton’s equation which states that the shear force resulting is directly proportional to the applied force and it is inversely proportional to the viscosity.
The SI unit for velocity is Pascal. Second (Pa S).
The other form of viscosity is called kinetic viscosity which is the ratio of a fluid’s viscosity to its density. It is given by ν (nu). It is a measure of the resistance of a liquid against flowing when it is under the influence of gravity. The SI unit of kinetic viscosity is a square meter per second.
Therefore, the above statement is true.

Identify the plant cell organelle in which photosynthesis takes place.
Help pleaseeee!
Answers
Answer:
chloroplast
Explanation:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
The plant cell organelle in which photosynthesis takes place is chloroplast. The correct option is D.
Plant cells and some algae contain unique organelles called chloroplasts. They have a green pigment called chlorophyll, which is in charge of absorbing solar light energy.
Chloroplasts utilize this light energy during photosynthesis to create glucose, a molecular energy source, and oxygen from carbon dioxide and water.
Because it enables them to transform light energy into chemical energy, which feeds their development and supplies them with nutrients, plants need this process to survive.
Because of their special adaptation for photosynthesis, chloroplasts are essential to the plant's capacity to produce food.
Thus, the correct option is D.
