HIV replication requires conversion of the genomic RNA present in the infecting virus to a double stranded DNA that integrates into a human chromosome. Unlike DNA polymerase, HIV reverse transcriptase catalyzes DNA chain elongation from either a DNA or RNA template. Azidothymidine (AZT) was the first effective drug used to inhibit HIV reverse transcriptase and went into clinical use in 1987 to treat AIDS. What best describes how AZT inhibits reverse transcriptase
Answer:
AZT inhibits reverse transcriptase enzyme.
Explanation:
AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.
The purpose of Phase II in rehabilitation is to control inflammation.
O a. True
O b. False
The correct answer is False.
Explanation
Rehabilitation has three main phases, the first of which is the first response to an injury, so the main objective in this phase is to defend the body against harmful substances, eliminate dead or dying tissue and promote the renewal of normal tissue. as well as alleviating pain, controlling the inflammatory response to injury and protecting the affected anatomical area. So you have to clean the wound, disinfect it, cover it, and in cases where it is required to put ice to reduce inflammation.
In the second phase the recovery of functional losses, so it is necessary to start making small movements in the affected area to reactivate its functions progressively.
The third phase is advanced rehabilitation in which functional training work begins with the aim of strengthening and putting the affected area back in a movement directed towards sports practice.
Therefore, the correct answer is False, because the inflammation control is done in Phase I and not in Phase II.

Answer: 1. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. brainliest?
Explanation:
4. In some varieties of camelia, flower color is controlled by codominance. The two alleles are red (R) and white (W). The heterozygous genotype is expressed as red and white.
D. What is the phenotype of a plant with the genotype RR?
E. What is the phenotype of a plant with the genotype WW?
F. What is the phenotype of a plant with the genotype RW?
Answer:
D. Red
E. White
F. Red and white
Explanation:
Co-dominance is a type of non-mendelian inheritance in which the two alleles of a gene are both dominant. Hence, they are both simultaneously expressed in the organisms phenotype.
According to this question, the two alleles (red (R) and white (W)) of a color gene in some varieties of Camelia are codominant. This means that both alleles will be expressed simultaneously in organisms that contain them.
- phenotype of a plant with the genotype RR is RED because only "R" alleles are present.
- phenotype of a plant with the genotype WW is WHITE because only "W" alleles are present.
- phenotype of a plant with the genotype RW will be BOTH RED AND WHITE, because they both phenotypically express themselves.

A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
Select all that apply
O
A
AB
B
Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

Answer:
Its first one then third one then last one
Explanation:
Im doing the diagonstic
Due to the tissue loss, a distinct line of bare white skeleton developed, which is how the disease got its name. The reef's food source changes when the corals are removed, changing the species makeup totally.
What is the cause of White band infection?A bacterial condition called the “white plague” is frequently mistaken for coral bleaching. According to recent investigations, the sickness comes in many forms. Corals lose tissue in every situation, exposing their exposed, raw, white skeleton.
Coral illnesses can spread through a variety of routes, including direct contact, water- or vector-borne transmission, and the relative weights of these routes can vary over time and across geographical areas and disease systems.
Therefore, A solid indication that an infection is present is if your band cell count is more than 10%. To identify the underlying cause of your bandemia, your doctor will advise more diagnostic procedures.
