Answer:
a. True
Explanation:
AZT is an abbreviation for azidothymidine and it is the first effective drug against the human immunodeficiency virus (HIV). Thus, azidothymidine is considered to be the first anti-retroviral drug used for the prevention and treatment of the human immunodeficiency virus (HIV).
AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.
Basically, the shape and composition of the reverse transcriptase plays a significant role in the interaction. Therefore, this anti-retroviral drug known as AZT may not work effectively if the shape and composition of the reverse transcriptase changes.
Furthermore, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.
Hence, the human immunodeficiency virus (HIV) possesses a high error rate.
Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

Genes are made of DNA and code for proteins
Answer:
B
Explanation:
Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.
What are genes made up of?Genes are made of DNA and code for proteins.This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
Therefore, Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.

Assuming 320,000 individuals develop Lyme disease each year, what is the attributable risk for the cumulative incidence of Lyme disease that comes from tick bites, if 300,000 of the new cases reported each year come from tick bites?
A. 93.75%
B. 16.00%
C. 6.67%
D. 6.25%
Answer:
The correct answer is - A. 93.75%
Explanation:
In the given question, there are total individuals with disease = 320000
in which, Disease in exposed people = 300000
the Disease in unexposed in people = 20000
Therefore, the probability of disease in exposed people would be
= Disease in exposed people/the Disease in unexposed in people
= 300000)/320000
= 0.9375 * 100
= 93.75%

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
Complete question:
Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. All proteins will show the same degree of divergence because different species experience the same selection pressure. All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.Answer:
3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
Explanation:
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE. All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSEAll proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUEAll proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSEAll proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.
The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.
In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.

what impact do you think the flooding river will have on the surrounding landscape
Explanation:
erosion
lossing of fine sidement
Floods Cause Sedimentation and Erosion riverbanks and forcing them to collapse, for instance, floodwater also can change the terrain. Floodwater suspends silt within the water as it drags debris from the eroding banks, which may deteriorate the water's quality and cause toxic algae blooms.
What about floods?Floods, the foremost common sort of natural disaster, happen when an more than water submerges normally dry ground.Floods are typically caused by lengthy, intense rain, rapid snowmelt, storm surges from tropical cyclones, or tsunamis in coastal areas.Flooding often happens when heavy rain falls for an extended period of your time over a short period of time, or when a river or stream overflows due to an ice or debris trap. Flooding also can happen when a levee or other water-controlling structure, sort of a dam, fails. Loss of human life is one among the negative outcomes of flooding. Infrastructure and property destruction. Dangers of landslides, erosion, and road closures. Damage of crops and loss of livestock.The most vulnerable areas to flooding are river floodplains and coastal regions, although flooding can also happen in places with exceptionally lengthy periods of heavy rain. These have the potential to harm coastal food supplies, limit coastal production, and deteriorate aquatic habitats.Learn more about floods here:
