minerals that a plant takes in from the soil
water that a plant takes in through its roots
sugars that a plant makes
Answers
Answer:
I'm pretty sure that it is the water the plant takes through its roots

This process is called photosynthesis, which means 'making out of light'. The foods are called glucose and starch. which is the process of making food for plants

Some silverware is made with the element silver (Ag). Over time, this silverware will turn black (tarnish) if it is not cleaned with a special solution. Why is this a chemical change?
Answers
Answer:
The tarnish is actually the result of a chemical reaction between the silver and sulfur-containing substances in the air. The silver is actually combining with sulfur and forming silver sulfide. Silver sulfide is black. When a thin coating of silver sulfide forms on the surface of silver, it darkens the silver. That’s what we call ‘tarnish.’
The time it takes to run a mile depends on the person running speed what is the independent and dependent variable as well as the constants
Answers
Independent: The person's running speed
Dependent: The time it takes to run a mile
Constants: The mile.

The independent variable stands on it's own. It will not change based on the Dependent Variable.
The dependent variable, the time it takes a person to run a mile, will change based on the Independent Variable, the person's running speed.
The constant is the mile. In an experiment, the mile, will stay the same. In each trial, it will stay the same, unlike the data for the independent and dependent variable.

The kidneys control the stable water balance in human body, filter some electrolytes from the blood, return part of them back into circulation, and excrete excess electrolytes into the urine, sodium and phosphate are dependent on the health of one’s kidneys.
The kidneys remove water-soluble waste products and toxins with urine, it produce an enzyme called renin which converts the angiotensinogen produced into angiotensin I and converted in the lungs into angiotensin II. Angiotensin II constricts the blood vessels and control blood pressure.
The kidneys produce erythropoietin, which help the body to create erythrocytes essential for the transport of oxygen throughout all the body parts.
