Proto oncogene are normal genes which are involved in cell growth and proliferation while the oncogenes are genes which have the potential to become cancerous. During cell division, proto oncogenes are strictly regulated, the cell division proceed appropriately and the division is terminated when the cell division is over. The cell division of the oncogenes on the other hand are not regulated, they continue dividing indefinitely.
 Using the gas pedal analogy, for the proto oncogenes,it will be GO, GO, GO, STOP. For the oncogenes, it will be GO GO GO GO GO GO [The 'GO' continues indefinitely].

Suppose that of a cohort of 150 mice in a mouse colony born in February, 125 are still at the end of March and 115 are still ali
kogti [31]

Answer: Survival rate up to start of April = 76.67%

Explanation: size of colony = 150mice.

Size of colony in February =125mice.

Size of colony in march = 115 mice.

1. Survivorship rate in February

= Size of colony / size in February *100.

= 122 / 150 * 100

= 83.33% to the nearest hundredth

2. Survivorship rate in march

= Size of colony / size in march *100.

= 115/150 * 100

= 76.67% to the nearest hundredth.

How does the body of a runner keep up with the demand for energy when cellular oxygen levels are low?
-BARSIC- [3]

Answer:

The correct answer is through anaerobic respiration in the cytoplasm.

Explanation:

Cellular respiration is of 2 types

1 Aerobic respiration Respiration that require oxygen to occur

2 Anaerobic respiration Respiration that do not requires oxygen.

During low oxygen level the body of runner keep up with the demand for energy by undergoing anaerobic respiration which includes Glycolysis.

  During anaerobic condition the functionally active body cells undergo glycolysis and with each glycolysis 2 molecules of ATP are generated which can some how boost the energy supply within runner"s body.
