I think it’s E (microtubules) i can be wrong but hopefully this helped
Well, you don't specify the parent traits, so I'll just do one for each...
If both parents are homozygous RR, then all 60 of the babies will be black
If both parents are homozygous WW, then all 60 of the babies will be white
If both parents are heterozygous RW, then there will be 15 black babies, 15 white babies, and 30 spotted babies.
If one parent is homozygous RR and one is homozygous WW, then all of the babies will be spotted
If one parent is homozygous RR and one is heterozygous RW, then 30 of the babies will be black, and 30 will be spotted
If one parent is homozygous WW and one is heterozygous RW, then 30 of the babies will be white, and 30 will be spotted.
i would say A.
the double bond in an unsaturated fatty acid produces a kink in the molecule. The bend in the carbon chain, however, is much more pronounced in the cis isomer compared to the trans isomer. For this reason, cis fatty acids (and triacylglycerols made from them) do not solidify like trans fatty acids. Due to the larger bend, the cis isomers cannot line up next to one another in as ordered a fashion as the trans isomers and can be more flexible.
