After eating a lunch of a sandwich and chips, the carbohydrates from the sandwich changes the amount of glucose in the blood. How does the body maintain homeostasis?
The body will stay in homeostasis by shivering to help increase metabolism of the food ingested from the lunch.
The body will try to increase the level of glucose in the blood which decreases after eating a sandwich.
The body will try to stay in homeostasis by increasing the heart rate to increase the level of glucose in the blood.
The body will try to decrease the level of glucose in the blood which increases after eating a sandwich.
To maintain homeostasis the body will try to decrease the level of glucose in blood which increases after eating sandwich.
What do you mean by homeostasis?"It is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions."When a person eats food containing carbohydrate, the blood glucose level increases.
This in turn stimulate pancreas to secrete Insulin which converts glucose to glycogen to maintain normal blood sugar level(thus maintains homeostasis).
Hence, the body will try to decrease the level of blood which increases after eating a sandwich.

Consider the aquatic phosphorus cycle. Phosphorus is the limiting nutrient for aquatic organisms. Decomposition naturally returns
phosphorus to the aquatic cycle, but phosphates from fertilizers, sewage and detergents can cause pollution in lakes and streams.
Over-enrichment of phosphate in freshwater can lead to which, when they die and decay, leads to
A)
a lower pH; acidification
B)
algal blooms; eutrophication
turbidity; decreased photosynthesis
D)
increased decomposition; poor growing conditions
Answer:
B
Explanation:
Carbon dioxide is called a greenhouse gas because it helps to trap heat from the Sun in Earth’s atmosphere. This keeps Earth’s temperature warmer than it would otherwise be. In this respect, how does carbon dioxide in the carbon cycle affect water in the water cycle?
A. It allows the oceans to contain more water than they would otherwise be able to. B. It leads to ocean water dissolving more salt than it has dissolved in the past. C. It enables more water to evaporate and enter the atmosphere. D. It causes more water to be frozen in ice caps at the poles
Carbon dioxide in the carbon cycle affect water in the water cycle in a way that it enables more water to evaporate and enter the atmosphere. (Option C)
How Carbon Dioxide Affects Water CycleCarbon dioxide molecules provide the greenhouse heating needed to maintain water vapor concentrations. When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapor drops. Dissolving carbon dioxide in the ocean creates carbonic acid, which increases the acidity of the water.

Question 3 of 11
which three sentences describe how a wildfire can harm a forest
ecosystem?
Answer:
The wildfires can damage forests that remove carbon dioxide. The wildfires also emit carbon dioxide, and these damaged trees do not have the strength to remove the carbon dioxide from the air. So this causes well-known global warming, which is a bad sign and is harmful to the atmosphere. And on top of that, the wildfires inject soot and aerosols into the air, causing quite complicated effects on the environment's ability to warm and cool on a regular basis.
Wildfires can ruin not just forests, but our world.
