Answer:
B
Explanation:
CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.
In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.
Answer:
They shrink and pull away from the cell wall.The cell becomes flaccid. It is becoming plasmolyed. in a very concentrated solution, the cell undergoes full plasmolusis as the cells lose water
<span>The thickness of the tissue layer
that is in focus is called the focal plane. the plane through the focus perpendicular to the axis of a
mirror or lens. It is controlled by the exposure
angle. The focal plane thickness decreases as magnification increases. </span>
There are three domains, Archaea, Bacteria, and Eukaryota.
Archer is located in the Archaebacteria kingdom.
Bacteria is located in the Eubcteria kingdom.
Eukaryotic is located in the Plantae, Fungi, Animalia, and Protista kingdoms.
Answer:
...cells switch to an emergency mode in which the body uses anaerobic metabolism during exercise to provide the necessary fuel for the muscles.
Explanation:
Anaerobic metabolism is the generation of energy by burning carbohydrates in the absence of oxygen. This happens when the lungs cannot place enough oxygen in the bloodstream to meet the energy demands of the muscles. It is used only for short periods of activity.
When there is not enough oxygen in the bloodstream, glucose and glycogen cannot be broken down into carbon dioxide and water. Instead, lactic acid is produced, which can accumulate in the muscles and degrade muscle function.
