Answer: During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).

Explanation:
The cell cycle is divided into two main divisions. The Interphase ad the M phase or the Mitotic phase.
Throughout Interphase, the cell is not dividing yet, but it is preparing to divide. It synthesizes the nutrients it will need, and grows in preparation to become two cells. This is actually the phase the cell spends the longest time.
Mitotic phase is when the cell starts to divide. It is separated into:
Prophase:
In this phase the chromosomes are condensed and mitotic spindles start to form. These spindles are made up of microtubules that will help later on to split the chromosomes. The nuclear membrane disappears so that the chromosomes will be free to move.
Metaphase
This phase is marked by the alignment of the chromosomes in the middle of the cell. They line up and you will find the asters at the opposite ends of the cell, where the microtubules stem from, attaching themselves to the center of the chromosomes, which we call the kinetochore.
Anaphase
In this phase you will see that the chromosomes are separated by the spindle fibers and are pulled at opposite ends of the cell. The cell then becomes longer by the other spindle fibers that are not attached to a chromosome.
Telophase
This phase is the end phase. The two sets of chromosomes are then enclosed by new nuclear membranes forming two nuclei and other cellular structures just as the cells are about to separate completely. As the two new cells move further apart, in plant cells a cell plate forms, dividing the two cells. The movement of the two cells splitting apart is called cytokinesis and it happens just as mitosis is about to end.
Attached is a picture of the cell cycle of a plant cell.

Multiply each planet by
![7.2\times 10^{-9}](https://tex.z-dn.net/?f=7.2%5Ctimes%2010%5E%7B-9%7D)
to get the diameter in meters.

Answer
Hi,
They are spread primarily by human activities.
Three methods that can spread invasive species is ; blowing by wind, splashed by rain and carried by animals.
Explanation
Invasive species are a kind of living organisms that are new to an ecosystem and can result into harm that is diverse .These species grow and reproduce at a quicker rate and spread rapidly with potential of causing more harm. In short distances, these organisms depend on natural dispersal ways to spread to other places. Example of an invasive species is Burmese pythons in the Everglades.
Hope this helps!
Answer:B
Explanation:
If lizards with long legs can run faster to escape the new predator than lizards with short legs can, then the long-legged lizards are more likely to survive and reproduce. The short-legged lizards are more likely to be caught by the predator, so they are less likely to survive and reproduce. Because of this, the majority of the lizards' offspring have long legs.
