Using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

Using the gas-pedal analogy oncogene, when the accelerator is stuck in down position and the brakes are not working.

Proto-oncogene:

Tumor suppressor genes:

Hence, we can say that oncogene, when the accelerator is stuck in down position and the brakes are not working.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
