Respiration and photosynthesis are considered complementary processes. Explain what is meant by this andhow they are both critical processes in the carbon cycle.

Answers

Answer:

The photosynthesis process produces carbon dioxides and water and breaks into carbon dioxide and water by forming ATP molecules, in addition to this cellular respiration. They are therefore both considered to be mutually complementary.

Explanation:

Photosynthesis and cellular respiration are additional processes, as photosynthesis products are used as cell respiration reactants.

Photosynthesis is a carbohydrate-generating process, whereas cellular respiration is a catabolism process that divides the carbohydrates into ATP.

Photosynthesis is the process of transforming light energy into chemical energy by green plants. During the process, the plants make use of solar energy in order to convert carbon dioxide and water into carbohydrates. And also releases oxygen into the atmosphere. Photosynthesis is called primary production because the food produced by the process makes the base of most ecosystem food chains. It stores energy at the bottom level of the food chain.

All animals are photosynthesized because their source of energy is glucose, but they are unable to produce glucose themselves, so they must rely on plants to obtain glucose.

And also during photosynthesis, oxygen that animals respire is released.

Breathing of the cell:

The process of breaking up the glucose molecules released by the living cells and stored as ATP molecules. In total, glucose and oxygen is a three-stage process that reacts to carbon dioxide and water.

In the following phases cellular respiration

• Glycolysis

• Oxidation of the pyruvate

• Citric acid / Cycle of cancer

• Oxidative phosphatide

how does the manipulation of an independent variable during a scientific experiment allow a scientistto find a cause and effect relationship between the variables

Answers

The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables.This is because the manipulation changes the results and measurements.

Frogs have internal and external structures to help them survive, grow, and reproduce. Name an internal and an external structure, an tell how these structures of the frog survive.

Answers

Answer:

Frogs have some important internal and external structures  that helps them to survive, grow and reproduce. Frog have almost similar internal anatomy to humans.

Frogs have the ability to respire through both lungs and skin. Skin is the external structure that helps them to respire in aquatic ecology.The skins helps to dissolves oxygen from the air and water and releases carbon-dioxide. Skin helps frogs to respire under water but if water do not have enough oxygen, frogs will drown.

An internal structure called liver is present in frog same as human beings. The liver releases chemical called bile that are utilized in digestion of fat and then emptied into the small intestine.

Hence, skin and liver are important for the survival of frog.
