Would water still be a polar molecule if it were not in the form of a v but rather were linear like carbon dioxide?
No, water would not be a polar molecule if it were not in the form of a v but rather was linear like carbon dioxide.
When two different atoms combine, due to their different electronegativities the electrons get shifted towards one atom which results in the molecule becoming polar.
The polarity of a bond is given by its dipole moment, which is a vector quantity and is represented using an arrow.
The H2O molecule is V-shaped and the CO2 molecule is linear, as shown in the adjoining diagram.
We can see that the dipole moments in the case of H2O have an angle between them, so they do not cancel each other and H20 becomes a polar molecule
While in the case of CO2, the dipole moments are in the opposite direction and cancel each other, so CO2 is non-polar.
If H2O were linear like CO2, then the dipole moments would have canceled each other and H2O would be non-polar.

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:

Explanation:
Intercellular junctions important in sealing the space between the cells and filling the gaps are called gap junctions. True or false?.
False,
Tight junctions are intercellular connections that are crucial for securing the gap between the cells.
Specialized tiny holes known as gap junctions "bridge the gap" between cells by joining their cytoplasm.
Tight Junction- The neighboring epithelial cells' upper lateral surfaces are encircled by tight junctions, which are thin belts that form fusion points or "kisses" at their intersections. They help the body create fluid compartments with different compositions and preserve the polarity of the cells.
Intercellular- The area between cells is known as the intercellular space. The cell's outer membranes surround it.

One occupational health risk prevalent is noise in heavy manufacturing and industrial settings and other settings like bars, farms, and cafeterias. The primary health concern is permanent hearing loss. The main concerns in noisy office spaces and schools are interference with expressing or understanding a message, annoyance, and stress.
Noise levels should be limited to acceptable levels to avoid the adverse effects of noise exposure. The most efficient noise reduction strategy is engineering changes to the noise source or the workplace environment.

If the fluid in the stomach has a highly acidic ph of 1 to 3, how does this fluid become slightly basic almost immediately after it leaves the stomach?
The food from the stomach reaches the small intestine, where upon the action of bile juice, the acidity of the food is reduced to base.
What is bile?Bile, a greenish coloured fluid is produced by the liver cells (hepatocytes).
Bile is stored in the gall-bladder and is released during digestion of food.
Bile constitutes water, salts, conjugated bilirubin, cholesterol, vitamins and some enzymes.
Bile is extremely important for the digestion of fat molecules in the body. Bile help in the breakdown of large fat molecules (emulsification) into smaller absorbable units.
Bile is also crucial for absorption of fat and vitamins such as A, D, E and K (fat soluble vitamins).
Bile turns the acidic food (chyme) to basic (chyle) when it reaches the duodenum, proximal part of small intestine. This is pivotal as it helps in further breakdown of food components by pancreatic juices.
