Answer:
A. acquired traits can be passed to offspring.
Explanation:
Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Answer:
B. 25%
Explanation:
Assuming the trait for teeth size is represented by the allele A. large teeth size is dominant and will be represented by A while small teeth size will be represented by a.
Assuming that the population of 1,000 [piranhas are all heterozygotes and they crossbreed with one another:
Aa x Aa = AA, Aa, Aa and aa
The ration of piranhas with large teeth to that of the small teeth is 3:1 or 75:25.
Hence, about 25% of the next generation of the population is ecpected to have small teeth.
The correct option is B.
The nucleolus is where the assembly of the ribosomes begin. Proteins are assembled on ribosomes. Ribosomes produce proteins by following coded instruction of the DNA. Eukaryotic cells contain an internal membrane system known as the endoplasmic reticulum.
