Explain why the use of peat is harmful to the environment
Answer:
Peatlands store a third of the world's soil carbon, and their harvesting and use releases carbon dioxide, the major greenhouse gas driving climate change. The biggest environmental risk from peatlands is if they catch fire, which happened spectacularly in 2015 in Indonesia on land cleared for plantations.
2. Give a reason why earth worms come out of the soil when it has rained.
for wallowing it?

explain how competition for biotic and abiotic factors, such as quantity of light water or food can affect the size of populations
Answer:
When there is a limited supply of water or food, organisms must compete for these resources in order to survive. Some will get to eat/drink but some others might not. As a result those organisms may die from lack of food/water, therefore decreasing the size of the population.

4. Describe the role of insulin in regulating blood sugar. What are the effects of adrenaline in the body?
5. Distinguish the role of testosterone and estrogen in human sexual development.
Answer:
yeah
Explanation:
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.
Alternative names for thyroxine
T4; tetraiodothyronine; thyroxin
What is thyroxine?
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys. Thyroid hormones play vital roles in regulating the body’s metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.
How is thyroxine controlled?
The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.
This hormone production system is regulated by a feedback loop so that when the levels of the thyroid hormones (thyroxine and triiodothyronine) increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone. This system allows the body to maintain a constant level of thyroid hormones in the body.
What happens if I have too much thyroxine?
The release of too much thyroxine in the bloodstream is known as thyrotoxicosis. This may be caused by overactivity of the thyroid gland (hyperthyroidism), as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre, which is a swelling of the neck due to enlargement of the thyroid gland. Other symptoms of thyrotoxicosis include intolerance to heat, weight loss, increased appetite, increased bowel movements, irregular menstrual cycle, rapid or irregular heartbeat, palpitations, tiredness, irritability, tremor, hair
how do soybeans replenish the soil of nitrogen?
legumes can get their nitrogen from the atmosphere

How does the fact that infants raised on breast milk were nine times less susceptible than bottlefed infants to lymphoma demonstrate that there may be a link between something in human milk and cancer-cell destruction?
Answer:
True.
Explanation:
The fact is true that the human milk helps in the destruction of cancers due to presence of Human Alpha-lactalbumin. Human Alpha-lactalbumin is a type of protein that is present in the breast milk that has the ability to kills the cancer cell so we can say that the great link is present between human milk and cancer-cell destruction and the infants that feeds on human milk has no chance of cancer disease.

What does a model of the carbon cycle show?
The amount of Earth’s carbon increases.
The amount of Earth’s carbon is constant.
The amount of Earth’s carbon decreases.
The amount of Earth’s carbon cannot be determined.
Answer:
The amount of Earth’s carbon increases.
Explanation:
Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year.

The endocrine system regulates the body through hormone release. Like the nervous system, what does the endocrine system help maintain?
A. homeostasis
B. reflexes
C. chemicals
D. neurons
Answer:
How is the endocrine system related to the nervous system in terms of its regulatory activity?
For one, the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses). The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived.

the impact of extinction to the environment
Answer:
Changing systems are inevitable but likewise bring harsh and even uncontrollable effectsExtinction is especially harmful because of the concept of mutual or coexistence theorems in which certain animals depend on others We will examine the food chain: Say that grasshoppers go extinct and the lizards that eat them exclusively now have no food source. That effect transcends into a higher order as it climbs up the food ladder. Effectively these said lizards could have been controlling the bug population and effectively the grasshoppers controlled smaller micro organisms which now are left to their own devices given the extinction of the grasshoppers.effectively those microorganism can damage ecosystems and dramatically change the composition or animals and vegetation that exist in said area.Answer:
1) it'll affect the chain reactions in the whole ecosystem and therefore, have a big effect on the environment.
2) if this happens then humans may lose the source of medicines as well, thus humans will be hit by a disease and there would probably be no cure, hence again affecting the biodiversity.
