Which best describes the nucelus atom?

The center and most sensitive part of the object or organism

Explanation:

Since everything is made of atoms there has to be something to keep all of them together that's where the nucleus comes in it's the one atom that differs from the other even though there are many different atoms the nucleus is special in that it's made up of neutrons and protons and maybe some electrons.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

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.
