Kumar is studying how Earth is warmed by sunlight. The followingshows his model of the sun and Earth.
Which process is mostly responsible for warming the soil in Kumar's model?
1. Conduction between the lamp and the soil causes the soil to warm.
2. Convection currents between the lamp and the soil cause the soil to warm.
3. Expansion of particles in the soil causes the soil to warm.
4. Radiation from the lamp reaches the soil and causes the soil to warm.

Garments cannot be made out of coconut fibre because they are very rough and are unable to be sew as it also the break very easily.

The coco fiber or coir is a fiber extracted from the husk of a coconut and is often used to make floor or door mats, mattresses and brushes. It is hard that is only suitable in making upholstery padding and sacking.

Answer:

Model

Explanation:

• A representation of a real object or system in its physics, conceptual or structural form is called the model of that object or system.
• A model only represents an object or system but is not the object/system itself.
• An example of the model of a system can be a model representing the water cycle which symbolically explains the systemic process and an example of a model of an object can be a globe which is a representative of the earth.
• The model tries to simplify our understanding of the given object/system and hence there is a little deviation from the real object/system.
• The purpose of the model is usually to provide basic knowledge regarding that particular object/system by giving a simpler representation.

Answer:

cellular respiration

Explanation:

Answer:

Metabolism i believe

Explanation:

The correct answer is option C

In glycolysis  2 molecules of NADH are produced  per glucose molecule, In transition reaction 1 molecule of NADH per pyruvate is produced and in Krebs cycle 3 NADH molecules per acetyl-CoA are produced. In Fermentation - NADH is produced but not for an electron transport chain.

Considering answers;

-fever

-constricted veins

-swollen veins

-confusion

Answer;

Swollen veins

Swollen veins might be a symptom of a person whose vein valves are not functioning properly and are causing fluid it flow away from the heart.

Explanation;

Valves are structures that are found in the circulatory system both in the heart and the veins.

They function to prevent the back flow of blood.

They do so by ensuring the continuous flow of blood in one direction.

If the valves are not functioning properly it may lead to various effects such as swollen veins due to the back flow of blood which may lead to the pooling of blood in the extremities.

The answer is C. swollen veins.

Good luck :)
