Answer:

The correct answer is a. Potassium hydroxide (KOH) preparations

Explanation:

Potassium hydroxide preparation is a simple test which is carried to identify the fungal infection invaded in skin, nails, vagina, etc. KOH degrade the keratin or mucous present on sample and clears the background which makes fungal cell more visible under the microscope.

In this method sample from infected area is collected and placed in the center of the slide then a drop of KOH is added on it. After this coverslip is put on the sample and the slide is heated gently to increase the reaction rate of KOH. Then the slide containing fungus is examined under the slide. KOH test is used for both yeast and molds. So the right answer is a.

When the membrane is at the potassium equilibrium potential, in which direction (in or out) is there a net movement of potassium
stellarik [79]
  • The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
  • At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.

<h3>At potassium's equilibrium potential, what happens?</h3>
  • At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
  • There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.

<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
  • Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
  • Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.

Question #8
Dima020 [189]

Answer:

needs the identities and profiles of possible victims.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security. Also, a data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

The database used for the identification of victims of earthquakes needs the identities and profiles of possible victims.

This ultimately implies that, the identities and profiles of possible or potential victims must have been collected and saved in a database prior to the natural disaster such as earthquake, tornado, wildfire, volcanic eruption etc. These database may be from a bank.

Why does water have a high specific heat
Marat540 [252]

Answer:

Water's high heat capacity is a property caused by hydrogen bonding among water molecules. ... When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid.
