Iron, water, and sugar are examples of matter that are nutrients.
True or false

Answers

Answer:

false

Explanation:

water is just good for you and some sugars are good

Iron, water, and sugar are examples of matter that are nutrients. So the statement is true.

What are nutrients?

The substances in food known as nutrients give us the energy needed for development, repair, and other vital living activities. Although not all nutrients are energy-producing, they are all required in one way or another. There are two groups of these nutrients:

macronutrients, which the body needs in huge quantities.micronutrients, which the body needs in minute amounts.

The environment may provide the aforementioned nutrients. Macronutrients give a living thing the energy it needs to run its metabolic system. They offer enormous energy that can be processed and used to produce energy. Fats, proteins, and carbs are examples of macronutrients.

Micronutrients supply the necessary building blocks for metabolism to function. To regulate bodily processes, they also create new tissues and replace ones that have been destroyed. Calcium, iron, vitamins, minerals, iron, and vitamin C are examples of micronutrients.

Therefore, iron, water, and sugar are examples of matter that are nutrients.

help me fast lol this is a biology related question.

Answers

Answer:

A=5

B=9

C=3

D=4

Explanation:

3+2=A, so A must equal 5.

A+4=B, since we know A equals 5 then 5+4=B, therefore B must equal 9.

2+C=5, then use algebra to solve by subtracting 2 from both sides. C=3.

3+1=D, so D must equal 4.

D.water has a high specific heat
ANSWER FAST PLSSS

Answers

Answer:

B. Water is a versatile solvent

Explanation:

Water is said to possess certain properties that gives it its unique attribute. These properties make it a vital component of life as it makes certain phenomena possible. According to this question, water, which makes up majority of urine content, aids the excretion of certain wastes such as nitrogenous molecules from the body.

Water is able to aid in this excretory function due to its VERSATILITY AS A SOLVENT. Water is said to dissolve more substances than any other solvent. This allows it to transport dissolved substances including waste products out of the body.

A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?

Answers

Answer:

A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Explanation:

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily

Table salt dissolving in water is the example of dissociation.

What do you mean by dissociation?

Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner.

Moreover, the dissociation of water is an equilibrium reaction in which one water molecule donates its proton to another water molecule.

Salts that are soluble in water dissociate into their ions and are electrolytes. Salts that are insoluble or only slightly soluble in water form very few ions in solution and are nonelectrolytes or weak electrolytes.

Explanation:

Identify the plant tissues in the three images.
A
B.
C

Answers

I originally asked for the images but I will give it my best shot at answering your question without them! :D

There are only three types of plant tissues:

1. Dermal

2. Ground

3. Vascular

The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the  the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue.

The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.

Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.

Image 1:

The dermal tissue is the outermost layer of cells that covers the plant. It is responsible for protecting the plant from the environment. The vascular tissue is a system of tubes that transports water and nutrients throughout the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.

In the image, the dermal tissue is the thin layer of cells that covers the surface of the leaf. The vascular tissue is the network of tubes that runs through the leaf. The ground tissue is the bulk of the leaf, and it is made up of cells that contain chloroplasts.

Image 2:

The epidermal tissue is the outermost layer of cells that covers the plant. It is responsible for protecting the plant from the environment. The vascular tissue is a system of tubes that transports water and nutrients throughout the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.

In the image, the epidermal tissue is the thin layer of cells that covers the surface of the stem. The vascular tissue is the network of tubes that runs through the stem. The ground tissue is the bulk of the stem, and it is made up of cells that contain chloroplasts.

Image 3:

The xylem is a type of vascular tissue that transports water and nutrients from the roots to the rest of the plant. The phloem is another type of vascular tissue that transports sugars from the leaves to the rest of the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.

In the image, the xylem is the dark brown tissue that runs through the center of the stem. The phloem is the lighter colored tissue that surrounds the xylem. The ground tissue is the bulk of the stem, and it is made up of cells that contain chloroplasts.
