The large stained-pink circle in the middle of each cell is most likely the cell nucleus.
Eukaryotic cells, which have a distinct nucleus and other membrane-bound organelles, have the cell nucleus, a membrane-bound organelle. DNA, which contains instructions for the development and function of a cell, is one of the genetic material found in the nucleus of a cell.
In microscopic pictures or stained cell samples the nucleus often appears as a distinct, round or oval structure with a darker stain than the surrounding cytoplasm. The staining clarifies the presence of DNA and shows where the nucleus is located within the cell.

Genomics is the subdiscipline in biology that is study of whole sets of genes and their interactions.
What distinguishes genomics from genetics?Genetics is the study of individual genes, while genomics is the study of the entire genome, or all of an organism's genes, interactions among those genes, and how the environment affects those genes, according to the National Human Genome Research Institute (NHGRI). Why is there a need to study genomics?Scientists may now study the genetic diversity of human populations thanks to genomics. When people think about population genetics, they frequently picture wild creatures being carried away by natural disasters, soil erosion, or predators.What kinds of genomics are there?Determine the structure of each protein encoded by the genome using structural genomics.

How could scientists use radioisotopes to study the function of the golgi apparatus?.
Scientists could use radioisotopes to study the function of the Golgi apparatus by tracking the radiolabelled sugars which are attached to the proteins within the Golgi apparatus.
Radioisotopes of radiolabelled sugars are attached to proteins within the Golgi apparatus and are used for their study of function and it is a membrane-bound organelle found in eukaryotes. It is made up of flattened, stacked pouches called cisternae. Proteins and lipids are moved, altered, and packaged into vesicles by the Golgi apparatus and delivered to specific locations. It is situated close to the cell nucleus and the endoplasmic reticulum in the cytoplasm.
In an experiment to determine the route secreted proteins follow, radioactively labeled amino acids are added to a growing culture of cells involved in protein synthesis. The secretory vesicles received the radiolabeled proteins from the Golgi apparatus, which then moved there and joined with the plasma membrane to release them outside the cell.

Nitric oxide accomplishes this by elevating cGMP levels.
NO is the unmistakable message. It dissolves in aqueous solution but is a gas. It is free radicals with free electrons that react with protein thiol groups to form new complexes. Unlike other second his messengers, NO does not require energy to enter or exit the cell. They can go wherever they want, but being reactive free radicals, they cannot travel very far. NO functions as a second messenger within NO-producing cells. It functions as a paracrine molecule that can travel 10-20 times the cell diameter to affect the biology of surrounding cells. It can form complexes with proteins such as hemoglobin, glutathione, and other proteins and be separated from those complexes.Therefore, increasing cGMP levels is necessary.

Damaged tissues are normally repaired through replacement of damaged or dead cells through a process called fibrosis. True or false?.
Damaged tissues are normally repaired through replacement of damaged or dead cells through a process called regeneration, hence, it is false.
Damage to tissues can occur internally or externally. When this occurs, a series of events called tissue repair are set in motion to contain the damage and initiate the healing process. One of these processes is called regeneration.
When the body replaces damaged or dead cells using cells of the same type, it is called regeneration. This occurs in most skin injuries like cuts, minor burns or scrapes and often doesn't leave any major scar. The internal organ that regenerates outstandingly well is the liver. Since the same type of cells are used during regeneration, the normal function of the organ is restored after regeneration.
Fibrosis occurs only when the damage done to the organ or tissue is excessive. Scar tissue called fibroblasts are deposited forming scar tissue to hold the organ or tissue together.

Explanation:
In cell biology, the process of mitosis, through which replicated chromosomes get divided into 2 new nuclei, is indeed a stage of the cell cycle. A mechanism of cell division creates genetically similar cells with a constant number of chromosomes is known as mitosis. Thus, the equational division is another name for mitosis. Generally, the S phase during interphase, which happens when DNA replication takes place, comes before mitosis. Telophase and also cytokinesis, which splits a cell's cytoplasm, and organelles, including cell membrane to form 2 new cells with nearly equal amounts of these biological components, frequently follow. The dividing of the mother cell producing 2 genetically similar daughter cells, or the mitotic (M) stage of the animal cell cycle, is defined by the several stages of mitosis taken collectively.

Within absorptive columnar cells re-synthesized triglycerides are incorporated into ______ before exocytosed through the basal side.
Within absorptive columnar cells re-synthesized triglycerides are incorporated into nascent triglyceride-rich lipoprotein particles, termed chylomicrons before exocytosed through the basal side.
Once consumed, triacylglycerol is hydrolyzed into free fatty acids and monoglycerides in the small intestine prior to absorption. Once these compounds enter the intestinal cell, they are used to resynthesize triacylglycerol.
This lipid is then incorporated into nascent triglyceride-rich lipoprotein particles, termed chylomicrons, for subsequent introduction into peripheral circulation.
Chylomicrons are secreted directly into the lymph before entering the blood stream. Once in circulation, triacylglycerol is hydrolyzed before crossing the plasma membrane of peripheral cells.
The primary enzyme that hydrolyzes triacylglycerol in plasma is lipoprotein lipase.
Lipoprotein lipase hydrolyzes triacylglycerol into free fatty acids and 2-monoacylglycerol. The enzyme is attached to the luminal surface of capillary endothelial cells via a highly charged membrane-bound chain of heparin sulfate-proteoglycans.
