Answer:
This question is incomplete as it lacks options, however, it will be answered BROADLY so the it can be understood enough to select the correct answer.
Please find the explanation below
Explanation:
Cells perform different functions and look differently because of the process of CELL DIFFERENTIATION. All cells arise from a single stem cell, which then gradually differentiates into different types of cells with different functions, as they divide.
At the molecular level, these different types of cells contain the same DNA sequence as rightly stated in the question. However, they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION.
Therefore, a blood cell and skin cell possess exactly the same DNA sequence but look different and perform different functions because of CELL DIFFERENTIATION in which some genes on the DNA sequence are expressed and others are repressed. For example, in the blood cell; the genes coding for certain proteins found in blood are expressed while every other gene is silenced or inhibited. This allows those cells to perform only blood-related functions.
Answer:
C. Genes C and D have an increased likelihood of undergoing recombination
Explanation:
Recombination in genetics is the phenomenon responsible for genetic diversity in species of organisms. It is the process whereby the DNA (carrying genes) are rearranged in a new way on a chromosome. It is when genes are recombined during meiosis or gamete formation.
However, recombination is only possible between two different chromosomal segments or same chromosomal segments that are far apart i.e. unlinked. The farther apart two genes are on a chromosome, the greater the chance for recombination to occur. It is, however, not possible for the recombination frequency of two genes to exceed 50% i.e. 50% is the maximum.
Genes C and D are located far on opposite ends of the same chromosome, which means that there is a likelihood or chance that recombination will occur between them. They cannot exceed 50% recombination rate

Complete question:
Imagine a newly discovered biological molecule that is mostly hydrophobic in its structure. This new molecule will most likely be classified as a___________.
a. Proteins
b. Lipids
c. Nucleic acids
d. Carbohydrates
Answer:
b. Lipids
Explanation:
Lipids are the biomolecules that are mostly nonpolar in nature. Storage lipids such as fatty acids and oils have small or long chains of hydrocarbons. This makes them largely hydrophobic. Similarly, phospholipids have fatty acid chains that make their hydrophobic component. Steroids are also the lipids that have a distinct sterol nucleus in their structure. This makes then hydrophobic. Therefore, most of the lipids have structural components that make them largely hydrophobic molecules. So, the newly discovered molecule is most likely a lipid.
