Hello! ATP stands for adenosine triphosphate, and ADP stands for adenosine diphosphate. The difference between the two molecules is that ATP has three phosphate group, and ADP has two phosphate groups. ATP is an unstable molecule, which means it will release energy when it becomes reduced to ADP, meaning it will break off one of its phosphate groups. Hope this helps, and let me know if you have any questions! ^-^
A comma splice is basically a comma fault which means- when two independent clauses are joined by a comma to make one complete sentence. And an independent clause is a clause that can stand alone as a sentence.
So, here in the passage- Option C is correct one.
Lady Liberty is a woman holding a torch, it represents freedom. This sentence can be successfully broken into two complete sentences. Like- Lady Liberty is a woman holding a torch. It represents freedom.
Hi~~
Human invasive use of outdoor and artificial lightning (AKA light pollution) has made us less able to see the sky and the stars. Light pollution affects our visual abilities to see objects in the sky by altering the colors and contrast of the night-sky, which makes astronomers less able to study the skies.
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.
