Answer:

The correct answer is option B.

Explanation:

The unit of Vmax and Vo is moles per second. Km refers to the concentration of the substrate, which is needed to attain the maximum reaction velocity. In case, when [S] is far greater in comparison to Km then Vo will be close to Vmax.

Vmax relies upon the concentration of the enzyme, Vmax enhances with the concentration of the enzyme and becomes steady when all the active sites of enzymes get occupied. Vo increases with the enhancement in the concentration of the substrate with time. Thus, the correct answer is option B, that is, Vmax is a special Vo when all the enzymes combine with the substrate.

Which characteristic do all protists have?
myrzilka [38]

Answer: They all survive in any environment.

Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.

I'll explain why the others aren't correct.

Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.

Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.

Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.

Let me know if you have any questions.

Ivan

Answer:

A.OSHA

Explanation:

The complete question is as follows:

Who mandates that employers of emergency responders must take certain measures to protect employees who are likely to be exposed to blood and other body​ fluids?

A.OSHA

B.UNICEF

C.CDC

D.USMLE

  • OSHA is the short form for the Occupational Safety and Health Administration  which is an agency of the  United States Department of Labor located in Washington D.C, USA.
  • The agency works to set and enforce standards for safe and healthy working environment for both men and women who work in private and public sectors.
  • The employers of OSHA have the responsibility to provide a safe workplace and ensure that no serious health hazards take place in the same.
  • Therefore the employers of emergency responders are mandated by OSHA to take measures to protect employees that are exposed to body fluids and blood.

A tissue sampler that is being used for a medical procedure is placed inside a saline solution. Unknown to the medical team, the
solong [7]

Answer: Water will leave the cell and the cell will shrink.

Explanation:

Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. <u>However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment.</u> The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:

  • <u>Hypotonic</u>: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell.
  • <u>Hypertonic</u>: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell.
  • <u>Isotonic</u>: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.

If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.
