The fossil that I believe are heterotrophs cannot produce their food which includes all animals, fungi, and most bacteria and protists. These fossils are A, C, and fossil D. The other kind of fossil is an autotroph which is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. This kind of fossil is fossil B.
True because carbohydrates are in the cell membrane.
I think it’s A because electrons actually taken up by oxygen molecules to make water.
Well, there is nothing given to list, but I kinda know because I actually liked biology class.
Advantages include:
Variation in offspring - this is really important to the survival of a species. Variety in DNA allows an offspring child thing being to be able to adapt to new environments and immune system attack and evolve gaining better and better traits for survival.
It also increases the chance of at least some offspring.
A pure-breeding double-mutant (apricot, blunt) has aabb genotype, wild-type wasp has genotype AABB. If we cross them:
P: aabb x AABB
F1: all the genotypes would be AaBb
If we ten cross the F1 dihybrids with the double-mutant line:
AaBb x aabb
F2: (table)
The four phenotypes are: 1) wild-type, 2) wild type apricot-short, 3) pale orange-wild type blunt, 4) double-mutant.
The possible haploid genotypes of the gamete it received from the F1 dihybrid: AB, Ab, aB, ab. AB and ab are nonrecombinant (nonREC), like those from parents, while Ab and aB gamets are recombinant (REC) .
