Answer:

C) Water will move out of the cell.

Explanation:

In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.

This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.

An adolescent client with an antisocial personality disorder has been admitted to the hospital because of drug abuse and repeate
Yuri [45]
The correct answer is "identifies the feelings underlying the acting-out behaviour ".
This statement shows that the adolescent is recognizing the feelings and is ready to talk about them. This willingness to express this indicates the development of insight and the sincere need to investigate the true source of these behaviours.
By stating that he will never behave like that again and that he will conform to society's norms, he is simply using expressions with no meaning to him. If he discusses seducing other adolescents, he is just manifesting the behaviour that led him to the hospital in the first place.

- Are living things only the product of their DNA? Why or why'not?
Darina [25.2K]

Answer:

No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.

List 4 targets of antibiotics.
Aleksandr-060686 [28]

Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.

1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.

2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.

3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.

4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.
