Explain which aquatic environments are more likely to have winter ice.
Answers
The freshwater ecosystem (rivers, ponds, oceans) is more likely to have winter ice because it does not contain salts as in the marine ecosystem, which prevents the water to freeze.
What are aquatic environments?Aquatic environments are the water contain environments. These environments include rivers, ponds, lakes, seas, oceans, etc. Aquatic environments contain aquatic animals like fishes, octopuses, frogs, crocodiles, etc.
Freshwater bodies freeze easily, and salt water bodies do not freeze easily because salt present in the water prevents it from freezing.
Thus, because freshwater ecosystems (rivers, ponds, and oceans) lack the salts found in marine ecosystems that keep the water from freezing, they are more prone to have winter ice.

The Sun is the ultimate source of energy for every process on this planet such as water cycle. Thus, the correct option is A.
What is Water cycle?The water cycle is a major biogeochemical cycle which shows the continuous movement of water within the planet Earth and the atmosphere. It is a complex system which includes many different processes such as evaporation, condensation, and precipitation. Liquid water evaporates into water vapor in the atmosphere, condenses to form clouds which then precipitates back to earth in the form of rain and snow.
The sun is the ultimate source of energy which makes the water cycle work. The sun provides energy or heat to almost everything on Earth.

holds the plant upright
contains xylem and phloem
transports water, minerals, and food

Answers
Answer:
All the above
Explanation:
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports fluids between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
Stems have four main functions which are:[1]
Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.
Transport of fluids between the roots and the shoots in the xylem and phloem(see below)
Storage of nutrients
Production of new living tissue. The normal lifespan of plant cells is one to three years. Stems have cells called meristems that annually generate new living tissue.

B. This is unreasonable, they ARE different.
C. This is incorrect sodium chloride does NOT have more atoms
D. This is simply incorrect :)
Answer: A
The difference between a molecule of sucrose and a molecule of sodium chloride is:
a. They are made up of different kinds of atoms.
d. They bond in different ways; sucrose involves sharing electrons while
sodium chloride involves stealing electrons.
A molecule can be defined as a group of two (2) or more atoms chemically bonded together, that form the smallest fundamental unit of a chemical compound and they are capable of taking part in a chemical reaction.
This ultimately implies that, a molecule refers to a group of two (2) or more atoms that are chemically bonded together by means of shared electrons and represents the smallest fundamental unit of a substance or chemical compound.
A molecule of sucrose is made up of a single (one) molecule or atoms of both fructose and glucose.
On the other hand, a molecule of sodium chloride comprises of an atom of sodium and an atom of chlorine.
Hence, we can deduce the following points from the above:
A molecule of sucrose and a molecule of sodium chloride are made up of different kinds of atoms.A molecule of sucrose involves the sharing of electrons through a covalent bond.A molecule of sodium chloride involves stealing electrons.Read more: https://brainly.com/question/20271431

Which statement describes one role of minerals during cementation?
Minerals bind sediments together.
Compressed minerals form new rock.
Sediments dissolve and bind minerals together.
Spaces between minerals are filled with sediments.
Answers
Explanation:
Sediments dissolve and bind minerals together
Minerals bind sediments together describes one role of minerals during cementation. So, the correct option is (A).
What is Cementation?Cementation is defined as ions present in groundwater being chemically precipitated between sediment grains to form new crystalline material, where the new pore-filling minerals form "bridges" between the original sediment grains, thereby they are tied together.
It is the hardening and welding of clastic sediments, which are formed from pre-existing rock fragments by precipitation of mineral matter in pore spaces, which is the final step in the formation of a sedimentary rock in which minerals bind the sediment together.
Thus, Minerals bind sediments together describes one role of minerals during cementation. So, the correct option is (A).
