PLEASE HELP!! Which of the following happens when cancer occurs?
1) the control of the cell cycle is impaired
2) cells cannot pass the G1 checkpoint
3) apoptosis or programmed cell death takes place
4) the cells can no longer enter the cell cycle
Explanation:
The answer is #1.
As cells become abnormal, old and damaged cells do not go through the cell cycle and can not regenerate like usual & the damaged. Any new cells are the cancerous ones that triple in number.
The disruption of cell cycle regulation is one of the main features of cancer. The correct option is 1.
The cell cycle is a strictly controlled process that makes sure that cells grow, divide, and are kept in good condition.
This regulating mechanism can be upset in cancer by mutations or changes in the genes responsible for controlling the cell cycle.
The cell cycle typically moves forward through a number of checkpoints that keep an eye on the DNA's integrity, the availability of critical resources, and the signals for cell division.
These checkpoints serve as controls to stop the division of damaged or aberrant cells.
Thus, the correct option is 1.

ROCKER
173 terawatts
1.73 terawatts
17,300 terawatts
173,000 terawatts
D. 173,000 terawatts
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.The Earth receives ≈174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.Since, 1PW=1000TW
Thus, 174 PW= 174*1000=174,000 TW.
Therefore, correct option is D.
