Assume that plant height and flower size in Four O'Clock plants display antogonistic phenotypes. Four O'Clock plants can be tall or short and the flowers can be large or small. Assume each trait is governed by alleles of a single gene and that each follows Mendelâ's first and second laws. You start with two pure breeding strains, one that is tall with large flowers and a second that is short with small flowers. You cross these two strains to each other to generate F1 plants. You self-cross an F1 plant and grow 342 of the resulting seeds into plants. You find that 195 plants are short with large flowers, 62 plants are short with small flowers, 59 plants are tall with large flowers, and 26 plants are tall with small flowers.

For the cross above- what is the phenotype of the F1 individuals?

A. Short with small flowers
B. Tall with small flowers
C. Medium height with medium size flowers
D. Short with large flowers
E. Tall with large flowers
F. Can't tell from the information provided

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.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
