Darwin realized that the often exquisite fit of species to their environment is primarily the result of

bagirrra123 [75]

Natural Selection.
An easy and important way to remember this is by thinking of a species - let’s say a bright white moth. For ages, these moths have survived beautifully, matching perfectly with the white tree bark they live on, until one day, a smoky building begins pumping its soot into the air. This air begins to change the color of the tree bark to black and the once hidden white moths are now plainly visible to birds who eat them easily. Fortunately, every now and then a moth is born who is darker than the rest - black as soot even. And so, the birds keep eating the white moths but missing the soot-colored ones. As time goes by, the soot-colored moths produce more and more similarly colored moths, who are well hidden from the birds AND after enough time, the only moths that remain are soot-colored. This is why so many species “fit” exquisitely into their environment. They have ALL adapted in some way similar to the soot-colored moth.

Glycolysis is a part of cellular respiration that takes place in the absence of oxygen.

Marta_Voda [28]

Answer:

Explanation:

Glycolysis is an anaerobic process - it does not need oxygen to proceed. ... They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.

If 2 parents-both heterozygous for particular traits in a dihybrid cross are mated, how many different phenotypes will result in

andrezito [222]

If the parents are both heterozygous for particular traits their genotype would be: AaBb x AaBb ( this cross would be the F1 generation while the P generation is the one that originated the parents).
This cross would result in the folowing genotypes:
AABB
AaBB
Aabb
aaBB
aaBb
aabb
Dominant for A and B: 9/16
Dominant for A but recessive for B: 3/16
Recessive for A but dominant for B: 3/16
Recessive for A and B: 1/16
ratio: 9:3:3:1
To answer you the possible phenotypes is difficult because your question is missing information about what each gene does, but I know it would be 4 different phenotypes.
