Water reabsorption takes place in the cortical collecting duct (CCD) cells, induced by the peptide hormone vasopressin. An increase in 3'5'-cyclic adenosine monophosphate (cAMP) levels in these cells leads to an increasing permeability of the CCD apical membrane to water.
<h3>What is hormones and duct ?</h3>
Your body uses hormones as chemical messengers. They move to tissues or organs through your bloodstream. They affect numerous processes, including growth and development, and work gradually over time. How your body converts food into energy is known as metabolism.
- Ducts are cell-defined passageways that can be used for either secretions or excretions. a gland is an organ that secretes substances in both plants and animals.

Answer: A
Explanation: there clearly isn’t no dinosaurs now so it can’t be b or c
Answer:
The Independent variable would be the pills that are being taken.
Explanation:
The Independent variable is the variable that you control because the Dependent variables depend on what the Independent variable is.
Answer:
Bacteriophages are attaching to bacterial cell wall and injecting genetic material.
Explanation:
Bacteriophage:
A bacteriophage (bacteria eater) is a type of virus that infects bacteria. Bacteriophages are composed of genetic material (DNA or RNA) enclosed in a protein shell or capsid.
Following are steps of bacteriophage infection:
- Bacteriophage attaches to cell surface receptors on the surface of the bacterium.
- Depending upon the type of phage, the bacteriophage either injects its DNA or RNA into the bacterium or enters as a whole. In this image, the bacteriophage T4 is represented which injects its genetic material into the host cell.
- The phage's genetic material hijacks the cellular machinery of the host and replicates itself within the host.
- After replication, the phages burst open the bacteria cell and are released. This is called the lytic cycle of bacteriophage infection.
- In another type of infection cycle, called the lysogenic cycle, the bacteriophage genome gets incorporated into the host genome, known as a prophage. This prophage lies dormant.
* The second step of the infection cycle is pictured here.
