Answer:
A
Explanation:
DNA polymerase is responsible for adding to the bases of the structure.
1-metaphase, since an ecuatorial plate is formed
2.prophase since the nuclear envelope is starting to dissapear
3.Telophase since new nucleae started to form around each separated genetic material
4.Interphase
5.Interphase
6.Interphase
7.anaphase since genetic material(chromsomes) is pulled to the poles of the cell
8.Interphase
9.Anaphase
10.Interphase
11.metaphase
12.telophase
13.Interphase
14.Prophase
15.interphase
16.interphase
17.metaphase
18.interphase
Answer:
The answer is C. The cell took in another ancient prokaryotic cell, which began living inside it.
Explanation:
- The Endosymbiont Theory explains the evolution of membrane bound organelles such as mitochondria and chloroplasts.
- According to the theory, mitochondria evolved when an ameoba like organism engulfed bacteria capable of cellular respiration.
- Similarly, chloroplasts were developed when the ameoba like organism engulfed cyanobacteria or blue-green algae capable of photosynthesis.
- These organisms survived inside the ameoba over millions of years to develop into mitochondria and chloroplasts.
- The fact that mitochondria and chloroplasts have their own circular DNA and ribosomes is evidence of the endosymbiont theory.
Answer:
they may "loop out" of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions
Explanation:
At the G1 checkpoint, cells decide whether or not to proceed with division based on factors such as: Cell size
