Answer:
1. DNA sequence
Since DNA is passed from parents to offspring, it is the most accurate way of
determining evolutionary relationships between species.
2. eukaryotic
3. protists and plants
4. species F/6
A.
Commuters drive personal vehicles to their places of work: offices, manufacturing plants etc.
Some may use car pooling or mass transit like buses. But too many want the luxury and convenience of coming and going on their own terms.
IMHO car pooling and mass transit needs to be used more to reduce environmental harm.
Answer:
The incorrect assertive is letter C. it forms pseudopodia for mobility.
Explanation:
The glycocalyx or glycocalyx is a wrapper outside the plasma membrane present in animal cells and some protozoa. The term glycocalix derives from the Greek glykys, sugar, and the Latin calyx, bark, a sugar peel. It consists of lipid-associated carobhydrates, commonly called glycolipids, and protein-associated caroboidates, called glycoproteins.
According of all functions we have about glicocalix, the assertive letter C is the only is not a function about this structure. The other ones, like allows bacteria to stick to a host or the environment, biofilm formation and protection a bacteria about the drying out process are function of the glycocalix.
Answer:
The genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2.
Explanation:
In the example given in the question, the color of the petals of snapdragon flowers are given with the An1 allele having full activity and the An2 allele being the null allele. For the F1 offspring, two snapdragon flowers are crossed, one with red petals which is An1An1 and one with ivory petals which is An2An2. All the genotypes for the F1 offspring will result in An1An2.
Then using this F1 offspring, the F2 offspring is found and the genotype of the F2 offspring will be An1An1 / An1An2 / An1An2 / An2An2.
So the genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2. One red petal snapdragon, 1 ivory snapdragon and 2 pink snapdragons.
I hope this answer helps.
Answer:
1 or 100%
Explanation:
Let the allele for seed shape be represented by S.
True breeding spherical shape seeded pea plant will have SS as genotype
True breeding pea plant with wrinkled seeds will have ss as genotype
Crossing the two: SS x ss
Progeny: Ss, Ss, Ss, Ss
Based on the assumption that spherical shape allele is dominant over wrinkle shape allele, all the F1 offspring will have spherical seeds.
<em>Hence, the probability is 1 or 100%</em>
