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.
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).

Food provides the carbon dioxide that is a product of cellular respiration.
Food provides the oxygen that is a product of cellular respiration.
Food provides the glucose that is a reactant in cellular respiration.
Food provides the energy that is a reactant in cellular respiration.
Answer:
I say food provides energy
Explanation:
Because you are gonna need energy before you play sports and then your gonna be tired after so your gonna need energy after that
Have a good day
Food provides the energy that is a reactant in cellular respiration. Therefore, option (D) is correct.
Why is food important source of energy?Nutrient-rich items are referred to as foods. Nutrients are substances that give the body the energy it needs for activity, growth, and all of its bodily activities, including breathing, digesting food, keeping warm, and they also give the body the building blocks it needs for growth and repair as well as for maintaining a strong immune system.
In general, it is made up of vital nutrients like carbs, proteins, lipids, minerals, and vitamins that are taken to support an organism's nutritional needs. These nutrients are also swallowed by an organism and used by its cells to maintain health.

Explain which aquatic environments are more likely to have winter ice.
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.

Group of answer choices
the sun
the sun
the moon
food
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.
Therefore, the correct option is A.

Marcus read that systems provide feedback, or the return of information. Feedback can either cause a change in the system or keep it stable. Melting glaciers are an example of positive feedback. Why is this considered positive feedback? PLZ HURRY
Melting glaciers would let the uncovered air and land warm, which speeds up the melting.
Melting glaciers would add more water to the hydrosphere, making it wetter.
Melting glaciers would change the land around it, speeding up erosion.
Melting glaciers would let the uncovered air and land warm, which speeds up the melting.
Melting glaciers would mean more ice at its top, which would slow the glaciers melting.

A plant's stem _____.
holds the plant upright
contains xylem and phloem
transports water, minerals, and food
all of the above
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.
