Photosynthesis is the main method by which primary production takes place in an ecosystem. What abiotic factor is a beneficial by-product of primary production?

Answers

The significant abiotic by-product of photosynthesis is oxygen. The main product of the process is glucose, which the plant uses as food. The general equation for photosynthesis is:

6CO2 (carbon dioxide) + 6H2O (water) = C6H12O6 (glucose) + 6O2 (oxygen)

It can be seen that plants are important to sustain life because they reduce the earth's carbon dioxide, and replace it with oxygen.

The answer is A: Oxygen

You and your body maintain homeostasis by

Answers

The body maintains homeostasis by maintaining a relatively constant environment within the body. The organ systems help control the internal environment so that it remains relatively constant. Most cells of the body are surrounded by a small amount of fluid, and normal cell functions depend on the maintenance of the cells' fluid environment within a naroow range of conditions including temperature, volume, and chemical content. For example: the digestive, respiratory, circulatory and urinary systems function together so that each cell in the body receives adequate oxygen and nutrients and so that waste products do not accumulate to a toxic level.

The glycolytic pathway must be supplied with its primary oxidizing agent ________ .

Answers

The answer is NAD+.

NAD+ is the primary oxidizing agent in the glycolytic pathway. Oxidizing agents gain electrons and thus, they are reduced in a reaction. In the glycolytic pathway, NAD+ server the oxidizing agent. It accepts electrons from the molecules, such as some intermediates of the glycolytic pathway. As the result, it is reduced to NADH which can serve in some reactions as a reducing agent.

Answers

Answer:

Option 3 is the correct answer

Final answer:

Biotic and abiotic factors in ecosystems

Explanation:

In ecosystems, biotic factors are the living components, while abiotic factors are the non-living components. Sorting the given items:

Biotic factors: Whale, Fish, Snail, Plant
Abiotic factors: Clock, Water, Paper, Glass, Aluminum, Wooden Ruler, Sand, Clouds, Corpse, Steak, Pork Chops, Salad, Bread, Hair, Finger Nails, Pipe, Cotton Fabric, Wool, Gold, Plastic, Grapes, Air

The biotic factors involve living organisms like whales, fish, snails, and plants, while the abiotic factors include non-living things such as clocks, water, paper, and metals.
