Even though they are classified into different kingdoms, protists and animals share some similar characteristics. Which is an example of a characteristic that algae and a lion have in common?

Eukaryotic

Explanation:

The kingdoms of Protista and Animalia both fit under the general domain of Eukarya, which basically includes all eukaryotic animals. Eukaryotic animals are those whose cells have membrane-bound organelles and a nucleus.

Algae is a type of protist, so clearly it must be eukaryotic. Similarly, lions are part of the Animalia kingdom, so it also must be eukaryotic.

Thus, a common characteristic can be eukaryotic.

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.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
