Answer:
B. Both cells use the same molecules for energy
Explanation:
The mitochondrion is considered the powerhouse of the cell and it is the only place that makes energy in the cell
As you stated before, cellulose is found throughout the cell walls of plant cells. Cellulose makes cell walls rigid, so that would indicate that cellulose is a carbohydrate.
Answer:
<u>d. the cells in primary cell cultures do not divide.</u>
A key difference between primary cell cultures and secondary cell lines is that<u> the cells in primary cell cultures do not divide.</u>
<u>hope</u><u> </u><u>it</u><u> </u><u>helped</u><u> </u><u>you</u><u> </u>
Explanation:
<em>The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.</em>
The correct answer is signal transduction.
Signal transduction also called cell signaling refers to the conduction of molecular signals from the external of the cell to its internal. The signals perceived by the cells must be conducted efficiently into the cell to make sure an effective response. This step is stimulated by cell-surface receptors.
There are three phases in the procedure of communication or cell signaling, that is, reception, transduction, and response.
Answer:
3 characteristic
Explanation:
1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.
2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.
3- Motility: if bacteria are motile than it's motility is easily visible in the media.
