With whom do you agree most? Explain why you agree with that friend.
Phantasy [73]

Answer:

I agree most with Natalie. Particles in a gas are very high energy/move around a lot, and well separated. Meanwhile, liquids particles don't move as much as the gas particles do,  but still have considerable movement and are closer together. Finally, solids are composed of particles that are tightly packed together and move the least out of the three states.

Hope this helps!

Sieve-tube cells and companion cells work together to transport
kicyunya [14]

Answer:

A) Tissue

Explanation:

Cells are the basic and fundamental units of all living organisms. Plants, like every other multicellular living organisms, are composed of cells that perform different functions. A group of cells that perform similar functions make up or form TISSUES, tissues that work together form the ORGAN, organs that work together to perform same function form the ORGAN SYSTEM.

In plants, sieve tubes and companion cells work together to carry out a similar task in plants, which is to transport nutrients and sugar inside the plant. Since sieve tubes and companion cells work together to fulfil same task, they collectively form a tissue in plants called PHLOEM tissue.
