7) Yes, the body does get all the energy from the sun. When we eat animals that eat plants, the energy from CR goes to the consumers.
8) No, CR is the result of photosynthesis, if no CR were around, photosynthesis could not begin.
9) Plants needs energy to help move things in and out of the cell. Plants also need energy to grow and reproduce.
4. How are atoms related to molecules?
Answers
Answer:
Every combination of atoms are molecules. A compound is a molecule made of atoms from different elements.
Explanation:
Atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.
What is the significance of the atoms and molecules?They are both significant because they are both the basic building blocks of matter, and atoms in a molecule are held together by various types of bonds, such as ionic bonds and covalent bonds, etc. Water molecules, for example, are made up of oxygen and hydrogen, which are the atoms that combine to form the molecule.
Hence, atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.

Identify the relationship between temperature and state change.
Answers
Answer:
Explanation:
"Both temperature and pressure can be measured, and state changes can be observed. When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)."

How do bacteria help plants grow?
They break down carbon dioxide into carbon and oxygen.
They protect plants from pollution from acid rain and hydrocarbons.
They change ammonia into nitrogen gas for plants to use to make proteins.
They change nitrogen into nitrates plants use to make proteins.
Answers
Answer:
They change nitrogen gas into nitrates for plants to make proteins.
Explanation:
Nitrifying bacteria and Nitrogen-fixing bacteria work together to convert nitrogen gas into nitrates which plants use to make DNA, RNA, and amino acids (which are used to make other proteins).
Bacteria help to plant growth by changing nitrogen (N element) into nitrates plants use to make proteins.
How do bacteria help plant growth?Bacteria help to plant growth by helping nitrogen assimilation during different metabolic processes.
This nitrogen is fundamental to synthesizing proteins, which are mainly composed of this element.In conclusion, bacteria help to plant growth by changing nitrogen (N element) into nitrates plants use to make proteins.

If conducted accurately identical investigations should produce similar results. Sometimes, errors like measurement errors, can
cause differences in results
Sandra and Jeremy are neighbors who tested different brands of seeds in their gardens for six weeks. They grew identical gardens
in their yards and recorded results. Each of them tried three brands of pea plant seeds and recorded the plants' heights at the end
of each week. They discovered Jeremy's plants were much taller on average than Sandra's plants every week.
Which statement describes a measurement error that may have caused such a significant difference in their results?
Sandra recorded her measurements in centimeters, while Jeremy recorded
his measurements in inches.
They both took measurements on Fridays, but Sandra took hers at 4:00 PM

Answer:
D Sandra measured her plants from the ground, while Jeremy measured his plants from the ends of their roots.
Explanation:
The statement that describes a measurement error is Sandra measured her plants from the ground while Jeremy measured his plants from the ends of their roots.
What do you mean by Seeds?Seeds may be defined as the unit of reproduction of a flowering plant, capable of developing into another such plant.
Three brands of pea plants are grown in the field of equal dimension, still, there may be a difference in their height that must be identified. This is surely due to a measurement mistake.
Therefore, it is well described above.

Which best describes the nucleus of an atom?
a. It is thee negatively charged part of the atom
b. It contains no mass.
c. it is made of neutrons and electrons.
d. It is the most massive part of the atom
Answers
Answer:
The answer is D.
I used the process of elimination to find your answer if you want to understand further look in my explanation. I hope I can help! Have a great day!
Explanation:
So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.

Answer:
C. There is not enough oxygen in the
atmosphere to support excessive numbers of
aquatic plants.
Explanation:
n excess amounts, both nutrients can cause an increase in aquatic plant growth and algae blooms, called eutrophication. These algae blooms live at the water surface, in order to easily access oxygen and sunlight. As a result, eutrophication prevents lower water levels from access to sunlight and oxygen in the air.
