Answer:
Explanation:
(1) The defective enzyme, which was suppose to break down drugs, is an oxidoreductase. Since, enzymes that break down drugs or metabolic enzymes perform there functions by oxidizing the drugs.
(2) Both codes are triplet codes for the enzyme; however the normal triplet code ought to be ATT, however there was a point mutation causing the "A" to be "C". These letters represent the bases in the DNA, <u>ATT is adenine-thymine-thymine while CTT is cytosine-thymine-thymine.</u>
(3) Further medications Henry is prescribed could include been taken with a drug/enzyme that will breakdown the actual medication.
Answer:
The correct option is A. they evolved from land mammals.
Explanation:
Evolution can be described as a process through which organisms in a species change over a period of time due to the natural selection of the environment. Those organisms that have many similarities in their functions or structures are considered closer to one another and have the same common ancestors.
The properties mentioned in the question about cetaceans resembles the properties of land mammals. For example, cetaceans lack gills and breathe air. Land mammals also do not have gills and need to respire for living. The cetaceans have fin bones which are similar to the limb bones in the land mammals. Hence, these observations show that cetaceas have evolved from land mammals.
Excision is the right answer :)
Answer:
Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.
Explanation:
Sickle cell anemia is a genetic condition that distorts the shape of the hemoglobin. This reduces the capacity of the red blood cells to carry oxygen. Another effect is that the distorted red blood cells come together forming a heavy and compact collection of cells that can block the flow of blood. The sedimentation rate is increased by sickle cell anemia.
