Dominik [7]

1. shotgun

2. inbreeding

3. cloning

4. Y chromosomes

5. The Human Genome Project sought to map a human's entire genome.

6. Inbreeding is a type of selective breeding that occurs when individuals with similar characteristics continue to be bred in an attempt to keep a certain set of traits. However, inbred organisms are genetically similar, and the probability that members of the population will receive mutated alleles leading to disorders is high.

7. Since no two humans have the same DNA, except for identical twins, forensics can take advantage of this fact by using DNA fingerprinting to solve crimes, convict wrongdoers, or overturn unjust convictions.

___ transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (atp).
eimsori [14]

Active transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (ATP).

Active transport is the means of transport of molecules across the plasma membrane with the help of energy. This method is usually used for the transport of molecule against their concentration gradient, i.e., from lower concentration to higher concentration.

Plasma membrane is the outer layer surrounding the cell. It is made up of lipid bilayer, proteins, carbohydrates and cholesterol. The lipid bilayer is amphipathic since the lipid head is hydrophilic and its tail is hydrophobic. The plasma membrane is semi-permeable in nature.

Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by
Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.  

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
