Which of the following describes why a drug may appear effective against a pathogen in clinical susceptibility tests but ineffec

tive in a real-life context? To be marked correct, you'll need to select all applicable statements, as there may be more than one correct answer.
1. Compared to controlled susceptibility tests, the drug may be less active in a real-life context either due to drug inactivation by body processes or as a result of drug solubility issues.
2. Drug susceptibility tests are typically performed at room temperature (much cooler than human body temperature).
3. In clinical susceptibility tests, drug concentration is well controlled compared to a real-life context.
4. Unlike in controlled clinical susceptibility tests, the number of bacteria varies between tissue samples.

Answer:

1. and 4.

Explanation:

For #1: Outside of a lab, different people's bodies may respond differently to the drug due to a one or many factors such as those listed in the response.

For #4: Pathogen mutations as well as bacterial growth and spread may render the drug incapable of curing the pathogen due to there simply being more bacteria in one person than the drug can handle.

I’m not sure that your choices are because it says select all that apply but I would tell the mother to stop giving the baby cows milk. The baby needs more iron which is in breast milk or formula if not she can become anemic and cows milk is not easy to digest for babies.

Andrei [34K]

Answer:

<em>The correct option is D) immigration</em>

Explanation:

Immigration can be described as the movement of an organism to another place for living. As the scenario in the question tells, the population of the endangered Philippine eagle could be seen only in one place hence we can say that the immigration rate of these organisms was zero because they could not be seen in any other place.

Other option, like option B, cannot be correct because mortality refers to the death rate and obviously many organisms of the species died due to which it became endangered.

An individual having two different alleles of a specific gene is described as being _________ for that specific trait.
borishaifa [10]

An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.

You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.

Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.

Which of the following statements about the smooth endoplasmic reticulum is/are correct?
Vlada [557]

Answer:

  • Liver cells are abundant in SER.  
  • The testes and ovaries are tissue types whose cells are abundant in SER.
  • Cholesterol is made in the SER.
  •  Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Explanation:

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

ER is the organelle at which all membrane lipids are synthesized.

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
