Hemodialysis is the process of artificially filtering waste products from the patient's blood.
<h3>What is
Hemodialysis?</h3>
A person whose kidneys are not functioning correctly undergoes hemodialysis, also known as hemodialysis or simply dialysis, to filter their blood. When the kidneys are in a condition of renal failure, this type of dialysis removes wastes like creatinine and urea as well as free water from the blood extracorporeally. One of the three renal replacement therapies is hemodialysis (the other two being kidney transplant and peritoneal dialysis). Apheresis is a different technique for extracorporeal separation of blood components like plasma or cells.

<h2>
Explanation:</h2>
- It is presumed that, over millions of years of evolution, abiotic molecules evolved into the self-replicating molecules by means of natural selection.
- Cyanobacteria, or blue-green algae is a bacteria which was one of the oldest fossils found on earth. These microbes conduct photosynthesis: using sun light, water and carbon dioxide to produce carbohydrates and oxygen.
- Cynobacteria played a major role in forming oxygenated atmosphere.
- The first living things on the planet Earths was single-celled micro-organisms which lack a well defined cell nucleus were known as prokaryotes, and bacteria belongs to prokaryotes ans hence among given options bacteria matches the most for the first life form on earth.
Result: Among the given choices bacteria was most similar to first living things on earth.
<span>The spherical object within a cell that controls its activity is the nucleus. The nucleus is the spherical organelle inside the cells. The genetic material can be found within the nucleus. So, the genetic information of the cell is inside the nucleus and therefore the nucleus can the activity of the cell.</span>
