Howard is constructing a model of the tree of life. which strategy would most likely ensure that all of earth's organisms are represented
somewhere in the model?

a. draw three branches for the domains: bacteria, archaea, and eukarya

b. draw four branches for the kingdoms. protists, fungi, plants, and animals

draw a long vertical line, and label dots on the line to represent examples of each kingdom

d. draw an outline of a tree, and label the leaves with the names of known species

The answer is A. Draw branches for the domains: Bacteria, Archaea and Eukarya

Explanation:

Three Domains of Life:

Bacteria, Archaea and eukarya are the three principal branches or domains of the tree of life that explains the evolutionary relationship between all living organisms.

The first two domains, bacteria and archaea comprise the prokaryotic unicellular organisms. The third domain, eukarya includes all eukaryotic organisms.

All other organisms have evolved from these three principal domains.

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.

this is math not biology xd
