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.
Answer:We see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth. As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.

Answer:
Air is a matter
Explanation:
Matter is anything that has mass and takes up space. So, in order to prove that air is matter, we need to prove that air has mass and takes up space. It's easier to prove that air takes up space, so let's do that part of the problem first.
Get a balloon and inflate the balloon with air. The balloon get larger as you put air into them. The only way that air could make them get larger is if air takes up space.
Also the balloon can be weight before air is added and after addition of the air. The weight will be much after adding air
conduction is solid
convection is liquid
radiation is anything that passes radiation
Answer:
b.You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
Explanation:
You are given an experimental problem involving control of a geneʹs expression in the embryo of a particular species. One of your first questions is whether the geneʹs expression is controlled at the level of transcription or translation is you measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
