ahrayia [7]3 years ago
7 0

Answer:

It helps us to see things.

It helps plants to make food and grow.

It is used in power satellites and space stations.

It is used in many electronic appliances.

The energy of light from the sun can be harvested to solar panels and can be used for domestic use since it is eco-friendly and cost effective too.

Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.
KiRa [710]

Answer:

corrugated cardboard tube - digestive tract

irregular surfaces on the corrugated tube - villi

pump - heart

Plastic tubing - blood vessels

Explanation:

The corrugated cardboard tube represents the digestive tract.  The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.

Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.

The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.

The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

Nitrogen is a nutrient that organisms need to produce (12) . Plants and animals cannot use the nitrogen that makes up a large pe
Dmitriy789 [7]

Answer:

12. Protein 13. Atmosphere 14. Nitrogen fixation 15. Plants 16. Consumers 17. Urinate 18. Decay 19. Decomposers 20. Ammonia 21. Denitrification

Explanation:

<em>12. Protein</em>

Nitrogen is essential to organisms. It is the main constituent of amino acids, which is the building blocks of protein in organisms.

<em>13. Atmosphere</em>

Nitrogen occurs naturally as gas in the earth’s atmosphere, accounts for about 78% of gases found in the atmosphere. This gaseous Nitrogen which is inert cannot be accessed by plants and animals for use.

<em>14. Nitrogen fixation</em>

For plants to be able to use the gaseous Nitrogen in the atmosphere, Nitrogen fixation has to take place. It involves the turning of gaseous Nitrogen in the atmosphere into ammonia. Nitrogen atoms is combined with Hydrogen atoms by  enzyme called “nitrogenase”. This enzyme is present in nitrogen-fixing bacteria.  

<em>15. Plants </em>

Nitrogen enters the food web when plants assimilate nitrogen compounds from the soil to form nucleotides, amino acids, and other important chemicals in life.

<em>16. Consumers </em>

Consumers are mainly animals that feed on plants in an ecological food web in other to be able to use the amino and nucleic acids formed from Nitrogen as a major component. Consumers can be categorized as primary, secondary, and tertiary consumers.

<em>17. Urinate </em>

Nitrogen is very much concentrated in the urine of animals and also in their faeces. As animals urinate, Nitrogen is being returned to the soil.

<em>18. Decay </em>

Decay starts, as organisms die. The organisms start decomposing.

<em>19. Decomposers </em>

Decomposers are the bacteria in the soil that break down the nucleic and amino acids in dead organisms into nitrates and ammonia through a process called ammonification

<em>20. Ammonia </em>

This is the end result of the decomposition of dead organisms by decomposers

<em>21. Denitrification </em>

Compounds of nitrogen are turned back into gaseous nitrogen by anaerobic bacteria. This prevents
