What causes sea floor to spread apart at mid ocean ridges?

Answers

Answer 1

Answer:

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.

An additional organic or inorganic substances which is added to soil or plants to increase the crop productivity is called as fertilizer.

It contain plant growth promoting nutrients like nitrogen, potassium, and phosphorus; For example, urea, anhydrous ammonia, etc.

The organic fertilizer is derived naturally from plants and animals. It enriches the soil nutrient level, encourage microbial reproduction.

Organic fertilizers are Agricultural Waste, Manure, municipal sludge etc.

How is co2 converted to glucose?

Answers

Answer:

Photosynthesis

Explanation:

Atmospheric carbon dioxide is converted to glucose during the Calvin-Benson cycle. This requires the overall reduction of CO2, using the electrons available from the oxidation of NADPH. Thus the dark reactions represent a redox pathway. NADPH is oxidized to NADP+ and CO2 is reduced to glucose.

Option (B) correctly represents the flow of energy in a living system because food chain starts with a producer.

What is a food chain?

Wild food chain shows who eats whom. Every living thing—from algae to blue whales—needs food. Each food chain is an energy and nutrient channel in the ecosystem.

In food chains, organisms are categorised into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.

Autotrophs produce their own nourishment. They start every food chain. Plants and single-celled creatures are autotrophs. Nearly all autotrophs make "food" (glucose) from sunlight, carbon dioxide, and water through photosynthesis.

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?

A: it would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.

B It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.

C Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.

D Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Answers

Answer:

D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Explanation:

According to this question, some types of syrup contains an entirety of glucose molecules. Hence, eating a syrup like this will have no effect on the person's ability to exercise, however, since glucose is the simplest unit of carbohydrate food sources, it gets digested easily.

Originally, glucose molecules, which are products of digestion, enter into our cells to be used to synthesize energy. However, for a syrup already made up of glucose molecules, the digestive system would not work as hard, since glucose is already small enough to get to her cells.

Glucose is the simplest form of carbohydrate, which is digested by the human digestive system. The syrups that are completely made of glucose molecules will not affect the person's ability to exercise.

The correct option is:

Option D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Glucose is the primary source of energy in all living organisms.

If a person is consuming a syrup made up of glucose molecules, it will not affect the ability of a person to exercise.

The glucose is present in simpler form, which will be directly absorbed by the cells to carry out functions and yield energy.

Thus, the digestive system will work normally because the cells are supplied with glucose and it won't affect the ability of the person to exercise.

Therefore, option D is correct.
