Answer: Plants obtain nutrients through photosynthesis, fungi obtain nutrients by decomposition, and animals obtain nutrients through digestion.
explain your answer and include how the variables
changed in the second part of the experiment.
Answer:
The data for the second part of the experiment support the second hypothesis . As the mass of the cart increased, the acceleration of the cart decreased. Since the increase in the cart's mass caused the decrease in the cart's acceleration, mass and acceleration are inversely proportional to each other, which is in accordance with Newton's second law.
Explanation: right on edg
Answer:
Ok so the answer is:
Sample Response: The data for the second part of the experiment support the second hypothesis. As the mass of the cart increased, the acceleration of the cart decreased. Since the increase in the cart's mass caused the decrease in the cart's acceleration, mass and acceleration are inversely proportional to each other, which is in accordance with Newton's second law.

2. metal
substances with only one type of atom
3. metalloid
an element that is malleable, polishes to a luster, conducts heat and electricity well, and tends to lose electrons in a chemical reaction
4. nonmetal
an element that is brittle, insulates heat and electricity well, and tends to gain electrons in a chemical reaction
The elements are substances having only one type of atom and metalloids have properties of both metals and nonmetals.
There are some properties of elements, metals, nonmetals, and metalloids:
1. Elements: Substances with only one type of atom.
2. Metal: An element that is malleable, polishes to a luster, conducts heat and electricity well, and tends to lose electrons in a chemical reaction.
3. Metalloid: An element with properties of both metals and nonmetals.
4. Nonmetal: An element that is brittle, insulates heat and electricity well, and tends to gain electrons in a chemical reaction.
Therefore, elements are substances that can not be further decomposed into smaller units by general chemical processes.
