Answer:
The answer is 17190 years
Explanation:
Original amount was 5730. To become 1/8 of the original amount, three (3) half life periods will demand because after first half life the amount will become 1/2 and after second half life, amount become 1/2 again (1/2 x 1/2 = 1/4). Third half life, the amount become half 1/2 again (1/2 x 1/2 x 1/2 = 1/8).
For the 3 half life periods we have original amount x numbers of half life periods = 5730 years x 3 = 17190 years
Answer:
The interphase: <em>DNA duplication</em>; The prophase: <em>Nucleus disappear</em>; The metaphase: <em>Chromosome line up at the middle of cell</em>; The anaphase: <em>Chromatids separation</em>; The telophase: <em>New cell membrane formed</em>; The cytokinesis: <em>Divided into two cell</em>.
Explanation:
A cell cycle includes 4 main phases: G0 phase, Interphase, Mitotic or Meiosis phase, Cytokinesis.
- G0: cell has left the cycle and stop dividing
- Interphase: including G1, S, G2: cell increases its size, and the DNA is duplicated to prepare for cell division.
- Mitotic or Meiosis phase: including prophase, metaphase, anaphase, telophase. In this stage, the nucleus and materials are divided.
- Cytokinesis: Cell divides into two daughter cells.
In my opinion it is tears.
Answer:
motor neurons
Explanation:
muscles contraction begins when the nervous system generates a signal.The signal, an impulse called action potential, travels through a type of nerve cell called motor neuron. The neuromuscular junction is the place where the motor neuron reaches a muscle cell.
The answer D sorry if I’m wrong
