Well there alot of challenges faced by biologist researchers during the research of infectious disease, however major of those include the followings:
1- Defining and measuring the fitness for pathogens across the scales
2- Developing models to capture the impact of co-infection on the evolutionary process
3- Modeling how pathogen characteristics shape the evolution of hose immune diversity
4- Understanding the maintenance of pathogen diversity
5- Developing the better models for the impact of genetic systems on pathogen evolution .

Answer:

The main challenge faced by a microbiologist researching infectious disease is to prevent the spreading of infectious disease to itself and others.

So to prevent the spreading of infectious disease microbiologist takes a lot of precautions like they work in an area which has negative pressure that do not allow the infectious particles to move out from that area.

They wear protective clothing that protects them from any spillage during the research work but even then it is a great challenge to scientists to prevent the spreading of these infectious diseases.

Some scientists and doctors working on ebola virus are killed by the disease ebola because they came in contact with this virus during their work.

In a macrotube (macrobroth) dilution susceptibility test, 1.0 ml of Mueller Hinton (MH) broth is pipetted into tubes 2 through 1

ExtremeBDS [4]

Answer:

In a macrotube (macrobroth) dilution susceptibility test,

1.0 ml of Mueller Hinton (MH) broth is pipetted into tubes 2 through 10, tube 11, and tube 13.

Two milliliters of MH broth is pipetted into tube 12;

1.0 ml of 200 micrograms/ml of ampicillin is added to tubes 1, 2, and 13.

A twofold serial dilution is performed in 1.0 ml amounts in tubes 2 through 10.

The standardized inoculum is diluted 1:200 and 1.0 ml is added to tubes 1 though 11.

The tubes are incubated for 20 hours at 350 C.

After this time, the tubes are examined for visual growth.

Tubes 6 through 7 are visibly turbid, while tubes 1 through 5 show no signs of growth. Tubes 1 through 5 are plated on blood agar, incubated overnight at 350C, and read for growth. Plates 1 through 4 show no growth while several colonies are observed on plate 5.

The MIC is:

The tubes 1 through 5.

Explanation:

The MIC is the tube which gets the lowest anti-biotic concentration showing no visible growth, and as tubes 6 through 7 are visible turbid.

The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.

Dr. Evil just discovered a way to prevent crossing over from occurring during meiosis in the gametes of her lab rats.

Alja [10]

Dr. Evil has just discovered a way to prevent mating from occurring during meiosis in the gametes of his lab rats. the effects her discovery would have on laboratory mice is that prophase I would be interrupted and there would be reduced genetic variation in the offspring of the mice. because crossover occurs during prophase I of meiosis I and results in genetic recombination, which promotes genetic variation. If this is avoided, genetic variation would be significantly reduced in the offspring.

<h3>What happens in prophase 1?</h3>

Prophase I – in this stage, the condensation of the chromosomes occurs; the temporary disappearance of the carioteca; disappearance of the nucleolus and the duplication of centrioles to the poles of the cell. In prophase, the exchange of genes (crossing-over) also takes place, through the exchange of pieces between homologous chromosomes.

With this information, we can conclude that Prophase I is the first stage of meiosis I. In it, the pairing of homologous chromosomes occurs and a phenomenon known as crossing-over can occur.
