Answer:
C. Diploid condition
Explanation:
A Karyotype is the pictorial display that shows chromosome arrangement and number in a cell. The Karyotype shows any abnormalities in the nuclear material (chromosomes). In a carrot plant that was cloned from carrot root, the clones should possess the same features as the original plant.
A Karyotype of both plants i.e. clone and the original plant should show that their cells have a diploid number of chromosomes i.e. Two sets of chromosomes. Since a carrot plant is a diploid organism.
Answer:
A) A mutation in a single gene can result in a defective protein.
Explanation:
This hypothesis states that one gene codes for one protein-enzyme, so consequently, if mutation occurs in that gene, the enzyme will not work properly. This hypothesis was very important for the fundamental discoveries of molecular biology, but it is oversimplified meaning that relationship between genes and proteins is much more complex.
Based on the attached Image;
The two species that are likely to have the most similar DNA base sequences
are C and D. An evolutionary tree or a phylogenetic tree, like the one shown on the image is used to indicate which ancestors gave rise to which descendants. The tree represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa. The tips of the tree represents groups of descendant taxa and the nodes represents the common ancestors of these descendants.
