Which would cause the body to release more water through the excretory
system?
A. Losing salt through the skin
B. Eating salty foods
C. Jogging in a gym
D. Sweating on a hot day
Answer:
B
Explanation: Hormone control of water and salt
Rehabilitation of water is regulated by the antidiervative hormone (ADH) in negative feedback. ADH comes out from the pituitary gland in the brain. Except for fluid levels in the blood, the hypothalamus causes pituitary to release ADH in the blood. ADH works to increase the absorption of water in the kidney. It puts more water back in the blood, increases the concentration of urine. When there is too much fluid in the blood, sensor in the heart indicates the hypothalamus due to a decrease in the amount of ADH in the blood. It increases the amount of water absorbed by the kidney, resulting in a large amount of diluted urine.
Aldosterone, a hormone that passes through the kidney, controls the transfer of sodium in the blood from nephron. When sodium level falls in the blood, aldosterone is released in the blood, which leads to sodium from nephron to blood. This induces water to flow into the blood via osmosis. Renin has been left in the blood to control aldosterone.
I think this is correct, I hope I help u. :)
Sweating on a hot day would cause the body to release more water through the excretory system.
What is excretory system?Excretory system refers to system of the body that consist of excrete organs like large intestine, skin which help to excrete or passed out waste product out of the body which can be toxic to the body.
Therefore, Sweating on a hot day would cause the body to release more water through the excretory system.

A. altitude, insolation, ocean currents, soil type
B. insolation, mountain ranges, ocean currents, soil type
C. insolation, latitude, mean June temperature, ocean currents
D. global winds, insolation, large bodies of water, ocean currents
Answer:
Global winds, insolation, insolation, large bodies of water, ocean currents.
Explanation:
Climate is the atmospheric condition of a place at a time such as temperature and rainfall . global winds, insolation, large bodies of water, ocean currents consist of four factors that play a role in determining climate. Insolation or solar energy determine climate of an area. Rays of sunlight hit the Earth and area near the equator which in one way or the order increase the temperature of an area.
lakes, oceans, and streams play a vital role in climate processes by serving as reservoirs for water, which can evaporate from the surface to fall later as rain or snow.
Bodies of water also reduce changes in temperature of surronding land areas .They make sure high temperature Don't get high and low temperature Don't reduce to low.
Ocean currents which move water from one place to another affect the climate of a place.

In this experiment, the independent variable they are testing is the type of solution in which the egg is placed.
What is the independent variable?In the data, the independent variables are the factors that do not depend upon the other factors, on the other hand, dependent variables depend on independent variables.
In the experiment they used three different solutions ate three different water solutions. One is pure, 100% distilled water, a second is 50% water and 50% corn syrup, and the third is 100% corn syrup, all are three independent solutions.
The independent variable is the cause which does not depend on any other factor in your study, all the solutions are different mixtures creating different variables.

Explain why decomposers are an important part of a food chain.
Answer:
Decomposers are vital to the food chain because they help recycle nutrients back into the system.
Explanation:
Decomposers like fungi and bacteria play most important role. They break down material that are dead or unused and turn them into nutrients in the fields or soil that plants use to grow.
Answer:
Decomposers are the organisms which change over complex materials into less difficult ones, often changing organic materials into inorganic ones. This, in turn, makes those assets available for use by other organisms. Decomposers, then, are crucial to the cycling of supplements in the ecosystem.
How can changes in trophic levels affect an ecosystem’s health and stability?
Answer:
Trophic levels are part of an energy cascade that allows for energy consumption, conservation, and retention.
Explanation:
By altering trophic levels in an ecosystem, there is shift between the readily energy available within one specfic trophic system. If you remove wolves, for instance, normal prey could increase en-masse. In this way, the removal of wolves allows for an energy expansion that increases and accelerates the growth of that prey species. In their growth, they attain their energy from elsewhere, say specific plants off which they eat.

Which of the following is NOT true about adaptation? A. Adaptation helps organisms survive in their environment. B. Adaptation can be a physical change in the organism.
C. Adaptation will always be the same regardless of the environment.
D. Adaptation can lead to evolution over many generations.
Answer:
c
Explanation:
Adaptation is a heritable behavioral, morphological, or physiological trait that has emerged through natural selection to preserve or improve an organism's fitness. Therefore, option (C) is correct.
What is adaptation?The term "adaptation" refers to a behavioral, morphological, or physiological trait that is inherited and has developed as a result of natural selection to maintain or improve an organism's fitness in response to a specific set of environmental conditions. Adaptation can be thought of as a heritable trait.
One useful illustration is the capacity to conceal oneself. Camouflage is an adaptation that helps an organism blend in with its surroundings so that it is not obvious to other organisms in those same circumstances. The organism is also able to protect itself from the hostile environment thanks to its adaptations.
