Savatey [412]

Answer:

The correct matching pairs are:

1) - B)

2)- E)

3) - A)

4) - F)

Explanation:

<u>Transferases (B)</u>: Transeferases is the class of enzyme that catalyzes reactions involving the <u>transfer of certain functional groups. (1)</u>

Example: Transaminase transfers nitrogenous groups

<u>Isomerases (E)</u>: Isomerases is the class of enzyme that catalyzes <u>isomerization reactions and intramolecular rearrangements. (2)</u>

Example: Triosephosphate isomerase interconverts aldoses and ketoses

<u>Oxidoreductases (A)</u>: Oxidoreductases is a class of enzyme that catalyzes <u>redox reactions (3) </u>which involves the simultaneous transfer of electron.

Example: Alcohol oxidoreductases acts on the alcohol functional group

<u>Ligases (F)</u>: Ligases is a class of enzyme that catalyzes reactions involving <u>chemical bond formation between two molecules. (4)</u>

Example: DNA ligase joins DNA fragments

The organelle identified in the picture as #10 helps the cell maintain homeostasis in what way? This organelle is the smaller wh
kondor19780726 [428]
Microtubule – serves as a framework of the cell –cytoskeleton.<span>
</span>
Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>

Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.

Identify the plant tissues in the three images.<br> A<br> B.<br> C
Bond [772]

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.
