Answer:
3.
Explanation:
A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface. The armpit of a human and a warm freshwater mud puddle are a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them
Answer:
Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer
Explanation:
Answer:
Binary fission
Explanation:
Prokaryotic cells do not have a nucleus. Binary fission is one of the methods of asexual reproduction in them. During the process, replication of circular DNA begins at the origin of replication and continues as the replication is bidirectional and the enzymes synthesize DNA in both directions.
As the replication comes to an end, the cell appear to have two circular DNA molecules entangled with each other. The septum grows towards the inner side as the chromosomes move toward opposite ends of the cell. This is followed by the formation of septum completely through the cell center, to make two separate cell chambers.
Answer:
C. the nuclei
Explanation:
All of our dna is stored in the nuclei.
