d. Both cell types are prokaryotic

During exercise, a person’s need a constant supply of ATP. To help us make ATP, the rate (speed) of which process increase?

a. mitosis
b. protein synthesis
c. cellular respiration
d. photosynthesis

1)b.both cell types have mitochondria

that they need for cellular respiration

2)c.cellular respiration

for ATP production

it has one origin of replication, but it proceeds in two directions - d)

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
