Question

the process of______, in which atoms attach to the exterior of a gene, render the gene capable of receiving and responding to biochemical signals from the body.
○ genotyping
○ methylation
○ glycolysis
○ hydroxylation
question 7 (4 points)
based on research, marijuana use by pregnant women has been linked to a lower volume of gray matter in the brain in addition to
○ preterm or low birth weight.
○ late birth with a high birth weight.
○ prolonged and more arduous labor.
○ cesarean sections and other surgical interventions.

Explanation:

First Question (Fill - in - the - blank about gene process)

• Genotyping: It is the process of determining the genetic makeup (genotype) of an organism, not related to atoms attaching to genes for signal response.
• Methylation: Methylation is a process where a methyl group (a group of atoms) attaches to the exterior of a gene. This modification can affect gene expression and make the gene responsive to biochemical signals.
• Glycolysis: It is a metabolic process that breaks down glucose, has nothing to do with gene modification.
• Hydroxylation: It involves the addition of a hydroxyl group, and is not the process of atoms attaching to genes for the described function.

• Research shows that marijuana use during pregnancy can have negative impacts on the fetus. One of the well - documented impacts is a link to preterm birth or low birth weight.
• "Late birth with a high birth weight" is incorrect as marijuana use is associated with negative fetal development impacts, not positive ones in terms of birth weight and timing.
• "Prolonged and more arduous labor" is not a typical association with marijuana use during pregnancy.
• "Cesarean sections and other surgical interventions" are not typically linked to marijuana use during pregnancy as a direct consequence related to fetal development like low birth weight or preterm birth.

Answer:

B. methylation
