Answer:
B. found in every living thing
Explanation:
Though most prokaryotes have both a cell membrane and a cell wall, there are exceptions such as Mycoplasma (bacteria) and Thermoplasma ( archaea ) which only possess the cell membrane layer. The envelope gives rigidity to the cell and separates the interior of the cell from its environment, serving as a protective filter. Hope this helped!
This is a biome.
Biomes really do cover large areas, for example there is one biome stretching from France to central Russia (temperate broadleaf forrest). They are characterized by a similar soil and a shared community of animals and plants.
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.
Explanation:
The G2 DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms that ensures that cells don't initiate mitosis until damaged or incompletely replicated DNA is sufficiently repaired. Cells that have a defective G2 checkpoint enter mitosis before repairing their DNA, leading to apoptosis or death after cell division.
