Depression that repeatedly occurs with the onset of autumn and winter is to seasonal affective disorder as chronic, low -grade depression is to dysthymic disorder. Seasonal affective disorder is a type of depression that is related to changes in seasons such that it begins and ends at about the same times every year. Dysthymic disorder is a smoldering mood disturbance characterized by a long duration as well as transient periods of normal blood.

Can somebody please label the parts of the frog?
zvonat [6]

Answer: As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk (see Vertebrates). The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom.

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

Which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water
BartSMP [9]

Answer:

The options are

a.cooling of the power plant

b.mining of uranium

c.storage of radioactive waste

d.monitoring the reactor

The answer is b.mining of uranium

Explanation:

Uranium is known as a radioactive element which is used as a fuel to power a nuclear energy plant. Mining of uranium could cause it to mix with air and water which results in contamination.

When contamination occurs and it gets into the body of humans or animals by inhalation or ingestion it poses a high risk of cancer and kidney damage.
