True. They form in warm clear marine enviorments
<em>Hello!</em>
<h3>The Answer Is: <em>Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.</em></h3>

because birds doesn't chew their food because they doesn't have teeth therefore the seed remains in one piece and they still can germinate.
Answer:
True
Explanation:
Cell cycle checkpoints are an important layer of control of the cell cycle. The cell cycle is a process by which cells divide.
There are 4 stages of the cell cycle G1, G2, S and M.
When the cell goes through the cell cycle, each stage has different processes that must occur for the cell to properly divide. During G1, the cell must grow to sufficient size and the environment must be favorable for cell division. During S phase, all the DNA must be properly replicated. during G2 the cell must prepare for division. During M, the cell actually divides.
There are 3 checkpoints throughout the cell cycle. The G1 checkpoint ensures the cell has reached sufficient size. The G2 checkpoint ensures the DNA has been properly replicated. The M checkpoint makes sure the chromosomes are properly attached to the spindles to split the DNA between 2 new cells.
Without these checkpoints, the cell can divide uncontrollably which can lead to cancer.
