Answer:
We can see that Lucy has ADA-SCID due to the constant infections that she has, generated by microorganisms that are easily fought by the immune system.
Explanation:
ADA-SCID is a hereditary cataresis syndrome that leaves a person's immune system highly weak and sensitive, failing to combat simple microorganisms that pose no danger to humans with the normal immune system. People with these syndromes basically have no defense in their bodies and often have infections caused by organisms that are easily fought by a healthy immune system. In addition, these infections can progress to more severe clinical cases.
Answer AND Explanation:
Normal: GGA CTC CTC
Abnormal: GGA CAC CTC
mRNA for normal DNA: CCU GAG GAG
mRNA for abnormal DNA: CCU GUG GAG
Amino acids for normal DNA: Proline Glutamic acid Glutamic acid
Amino acids for abnormal DNA: Proline Valine Glutamic acid
Answer:
C. Mitosis produces cells that are identical genetically, while meiosis produces cells that differ.
Explanation:
Answer choice A is incorrect because mitosis actually creates identical cells while meiosis creates 23 genetically unique pairs.
Answer choice B is incorrect because neither produces "quicker" or "easier"
Answer choice D is incorrect because it is actually the opposite: Mitosis only has one cell division that provides two daughter cells, while Meiosis has two divisioins that result in four cells.
Thus, the most logical answer is C. Feel free to message me if you have any more biology questions!!
Haven't done living environment in a few years, but the assumption should be "2) female offspring would be unable to bite humans, since they can't fly" and the method would be 3) biotechnology.
The answer to "assumption questions" can usually be figured out by just reading the information given. Since its talking about FEMALE mosquitoes BITING HUMANS and spreading diseases, the second answer is most relevant.
The second question requires you to understand the definitions of each answer choice (or atleast the correct one). The most relevant answers would be 2 and 3, as those refer to humans changing the characteristics of a species. However, again, referring to the information given, we know that the research being conducted is with the DNA of male mosquitoes being altered. This is not an example of selective breeding, but rather of biotechnology.
