Answer:
Agree
Explanation:
The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.
I believe the answer is B. C3H8
Answer:
Phagocytosis in the inflammatory response
Explanation:
In the given question, the person is injured and is bleeding. This injury initiates the inflammatory response, a type of immune response to the injured site.
This inflammatory response recruits the defensive cells flowing in the blood called white blood cells to the injured site.
The white blood cells interact with these foreign bodies and may help eliminate foreign material.
One of the mechanism by this response is the phagocytosis which occurs when the monocyte WBC interact with the pathogen and engulf and degrade it.
Thus, Phagocytosis in the inflammatory response is correct.
The normally treated group is called the control. Scientists use control to lessen the effects of variables. The accuracy of the results becomes higher. Control groups can be positive or negative depending on the expectation of a phenomenon that would occur in it.
Answer:
The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.
Explanation:
mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.
If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins. mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.
