It’s not cause by convection because it’s a cause by fluid areas, where cold and hot circulate. But, conduction is when a hot object touches another object
Answer: Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
Explanation: It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
The conclusion drawn from the fact that DNA analysis of all chloroplasts reveals that they are monophyletic is Endosymbiosis of the same species of cyanobacteria occurred multiple times in cells that evolved into red, green, and brown algae.
Most scientists agree that non-photosynthetic eukaryotic hosts originally acquired photosynthetic prokaryotic endosymbionts, which led to the formation of plastids. It is also acknowledged that non-photosynthetic eukaryote hosts frequently took on photosynthetic eukaryotes as endosymbionts in order to create secondary plastids.
It is shown that primordial plastids had a single, or "monophyletic," genesis. The red, green, and glaucophyte plastids are thought to belong to a single group, either as a subgroup of oxygenic photosynthetic prokaryotes or as a sister group, according to the monophyletic hypothesis of plastid genesis.
Therefore,Endosymbiosis of the same species of cyanobacteria occurred multiple times in cells that evolved into red, green, and brown algae.

Chime...its 100% true, I searched it on google and found the answer, just google your questions sometimes and the answer will pop up sometimes so you dont have to waste points :)
Answer:root tips and germinating seeds
Explanation: cytokinesis is a plant hormone found in the growing parts of plants where it induces cell division.it does this by accelerating the events of the gap phase to get into the proper Division.As an hormone,it serves as specific chemical signals between cells.it is abundant in meristematic cells as those cells are always in a state of division.cytokinesis is involved in the enlargement of growing parts of plants as auxin are involved in the enlongation of growing parts.
