Explanation:
Blood vessels constrict and platelets release fibrin proteins, which tangle together to form a clot and close the wound when the skin is penetrated. The blood arteries then dilate again, allowing white blood cells to flood the wound. These go after any bacteria that managed to get through the blockage.
Cuts and scratches are damaged regions on the skin's surface. A cut is a line of damage that can penetrate the skin and into the muscular tissues beneath it, whereas a scratch is superficial damage that does not enter the lower tissues. Cuts and scrapes can bleed, turn red, develop infected, and leave scars if they are not treated promptly.
Your skin may begin to bleed after a cut, scrape, or abrasion. Because the damage fractures or rips the small blood vessels just beneath the skin's surface, this occurs. The platelets blood come to the rescue when your body needs to stop the bleeding.
Answer:
P53 protein is a tumor supressor protein.p53 is so named because it has a molecular weight of 53 kd.p53 is encoded by TP53 gene.p53 is called the guardian of the genome because it helps to maintain balance between live cells and dead cells.
Explanation:
p53 is an important regulatory protein of apoptosis or programmed cell death.p53 helps in the destruction of damaged cells or cell with damaged DNA thus ensuring that every cell in our body has normal DNA.
Mutation of p53 result in the generation of cancer because p53 is a potent regulator of cell cycle.
p53 destroy the damaged cells by activating p21 which in turn blocks G1 cyclin CDK thus blocking the cell to enter the S phase or synthesis phase.
Mutation in p53 result in the progression of abnormal cell through the cell cycle which ultimately result in formation of abnormal protein thus giving rise to the onset of cancer.

Wash your hands
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
Antibiotics fight bacterial infections either by killing bacteria or slowing and suspending its growth.

Answer:
Cilia and flagella arise from the centrioles
Explanation:
Some cells have projections made up of microtubules and covered by extensions of the plasma membrane.
These projections can be cilia or flagella.
Centrioles are also made of microtubule from which the cilia and flagella arise. It also takes part during cell division
Basal bodies are protein structures found at the base of cilia and flagella. It functions as a site starting point for the growth of microtubule for the cilia and flagella
