What is an Osteocytes?
Osteocyte, a cell that exists in the substance of full fledged bone. It possesses a little chamber called a lacuna, which is contained in the calcified framework of bone. Osteocytes get from osteoblasts, or bone-shaping cells, and are basically osteoblasts encircled by the items they emitted.
Cytoplasmic cycles of the osteocyte expand away from the phone toward different osteocytes in little channels called canaliculi. Through these canaliculi, supplements and side-effects are traded to keep up with the suitability of the osteocyte.

What type of bonds occur in tertiary and quaternary structures to cause a ""globular"" look?.
The types of bonds that occur in tertiary and quaternary structures to cause a ""globular"" look are: non-covalent bonds and one covalent bond which is disulfide bond.
The quaternary structure of the protein is formed when two or more subunits are joined together. These subunits individually have their own primary, secondary and tertiary structures. The example of protein exhibiting a quaternary structure is hemoglobin.
Non-covalent bonds are those that occur only between the molecules and not between the atoms of a molecule. There are various types of non-covalent bonds. These are: hydrogen bonds, ionic bonds, Van der Waals forces, etc.

Sister chromatids specifically separates during mitosis.
What is mitosis?
Chromosomes that have been duplicated are divided into two new nuclei during the cell cycle phase known as mitosis. With a fixed number of chromosomes, genetically identical cells are produced during the cell division process known as mitosis. Thus, equational division is another name for mitosis. The mitotic process is broken down into stages that mark the end of one set of activity and the beginning of the next. Preprophase, prophase, prometaphase, metaphase, anaphase, and telophase are the stages that apply only to plant cells. Chromosomes that have already been duplicated condense and attach to spindle fibers during mitosis, which pulls one copy of each chromosome to each of the cell's two opposite sides. Two daughter nuclei with the same genetic makeup are the outcome.Learn more about the Mitosis with the help of the given link:

The nephron consists of the renal corpuscle or glomerular capsule, and the renal tubule.
The renal corpuscle is?A renal corpuscle—also called a malpighian body—is the portion of the kidney's nephron that filters blood. A glomerulus, or group of endothelial-cell-lined capillaries, and a glomerular capsule, also known as Bowman's capsule, make up the structure.
The glomerular capsule is the first part of the nephron to filter substances out of the blood and into the renal corpuscle.
The glomerulus is encased in a cup-shaped sack called Bowman's capsule, which is a component of the nephron. The "Bowman's space" in Bowman's capsule, which is connected to the proximal convoluted tubule of the nephron and serves as the start of the urinary space, is enclosed.
As blood enters the Bowman's capsule in the nephrons, excess fluids including water, salt, and metabolic waste products are drawn out of the blood. Glialular filtrate is the name of the fluid found in the Bowman's capsule. Except that it contains almost no protein, it is comparable to blood plasma.

A traumatic injury to a joint involving the soft tissue is called a sprain.
Generally, 'soft tissue' is commonly used to describe muscles, tendons and ligaments. They connect, support and surround the bones. A traumatic injury to the ligament is called a sprain, and a traumatic injury to the muscles and tendons is called a strain.
A sprain or torn ligament occurs when the ligaments in a joint get torn due to a sudden movement so extreme, it exceeds the ligament's normal range of movement. In a joint, ligaments are inelastic, tough collagen fibers that connect two or more bones together.
When a muscle or tendon is overstretched and gets torn, it is called a strain or a pulled muscle. A tendon is a fibrous tissue that connects muscles to bones.
The major difference between a strain and a sprain is that a strain is an injury to the muscles and tendons, while a sprain is an injury to the ligaments. Both injuries are usually mild and can be treated at home using ice, compressions, elevation and rest.

During diabetic ketoacidosis the ph of the blood decreases. how does the body respond and why?
The overproduction of acetoacetic acid and -hydroxybutyric acid causes acidosis in DKA. These two ketoacids entirely separate at physiological pH, and the extra hydrogen ions bind the bicarbonate, lowering serum bicarbonate levels.
Why does diabetes cause a drop in blood pH?
As a result, the liver creates beta-hydroxybutyrate, an acid that gives the brain and muscles energy through the bloodstream.
However, if the body continues to use fat stores as fuel, this causes the blood's pH to drop as the sugar molecules circulate in the blood unused.
