Which of the following accurately explains why human siblings differ in appearance from one another? A). each of them inherits a unique member of chromosomes.
B). gametes have higher rates for mutations, which allow for more genetic diversity.
C). alleles are interchanged during meiosis, which results in genetically distinct offspring.
D). genes are rearranged during mitosis, which results in new combinations of chromosomes.

C

Explanation:

About the options:

A) That's not true. Every human been inherits the genes from it's parents.  

B) That's not true. Gametes have no higher tendency for mutation, that could be dangerous: if a deletirous mutation appears, the organism could die. Mutations don't happen for a purpose, so, mutate can be extremaly bad - and usually is.

C) That's true. One of that interchangends is the crossing-over: nearby chromosomes exchanges parts. It happens in the beginning of meiosis.

D) That's not true. Mitosis is a procedement of cloning cells. If a new combination happen, then we have a mutation and the cell will be probably killed.

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.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
