The answer is A. Nucleus-forms peptide bonds
Answer:
What information on a pedigree can tell you whether a gene is on a autosome or not a sex chromosome? If in a pedigree, the occurrence of the disorder is 50/50 between females and males, then it shows that it is autosomal. If the disorder is mostly shown in males then it is a sex-linked trait.
Explanation:
Answer:
tt
Explanation:
Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.
tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.
So it would make sense that tt is the choice.
The answer is; It provided clues for scientists to develop a hypothesis about the origin of flight.
Scientists now postulate that dinosaurs are the ancestors of birds. This because the Microraptor is a dinosaur with feathers in all its limbs. It is also the smallest dinosaur to every been discovered and has been compared with the Archaeopteryx (involving even genetic sequencing) to hypothesize how dinosaurs evolved into birds.
Answer: Twenty five (25) of the chicks will be black.
Explanation: A cross between two heterozygous chicks (Bl/bl+) will produce four chicks; one will be Bl/Bl, two will be Bl/bl+ while one will be bl+/bl+.
A break down of the phenotypes is as follows:
Genotype ==> Phenotype
Bl/Bl ==> Black
Bl/bl+ ==> intermediate
bl+/bl+ ==> blue.
Since one out of four offsprings (1/4) is black, therefore if the two chicken produce 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25.
