Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​

Answers

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M

The function of glomerulus and Bowman's capsule of the nephron is to?
(A) reabsorb water into the blood
(B) eliminate ammonia from the body
(C) reabsorb salts and amino acids.
(D) filter the blood and capture the filtrate

Answers

Answer:

The function of glomerulus and Bowman's capsule of the nephron is to filter the blood and capture the filtrate (option D).

Explanation:

The set of glomerulus and Bowman's capsule is known as the renal corpuscle, and it is the structure responsible for the filtration of blood and its uptake as urine, which passes to the renal tubular system.

The renal glomerulus is the functional unit of the kidney, and is the structure responsible for filtering the blood that arrives through the renal capillary, to eliminate the waste products present in the blood.

Bowman's capsule surrounds the glomerulus and constitutes the second component of the filtration of blood plasma, in contact with the renal tubular system.

The other options are not correct because:

    A. Reabsorb water into the blood occurs in the renal tubules.

    B. eliminate ammonia from the body. Ammonia is one of the waste substances, converted to urea, that is eliminated by the kidney.

    C. reabsorb salts and amino acids, occurs in the renal tubules.

why is forcing the cell to increase the rate of the cell cycle lead to error in DNA replication

Answers

We tend to think of the process of DNA replication as this well laid out stoic process like a factory line. It isn't. The DNA doesn't lie in a straight line for the DNA polymerase to read and it is moving - not static. It is tangled and curved. First understand this is the molecular level. Things don't "think", bacteria don't make decisions, they have no neurons. Everything is a chemical reaction that very often depends on osmotic pressure of one concentration being stronger then another both inside of the cell and outside. Nothing is empty though even at that level there is a lot of "nothing".

in an appropriate design experiment, a scientist is able to test the effect of?

Answers

Answer:

This question is incomplete as it lacks options, the options are:

A) a single variable

B) multiple variables

C) the hypothesis

D) scientific observations

The answer is A

Explanation:

An experiment is conducted to solve a particular problem or find answers to a given scientific question. In an experiment, which usually consists of variables, only A SINGLE VARIABLE is tested at once.

This means that the effect of a variable called INDEPENDENT VARIABLE is tested at a time. The independent variable is the variable that is changed or manipulated in an experiment. This means that only a SINGLE VARIABLE can be changed at at time in an an appropriate design experiment.

C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.

D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.

​

Answers

Answer:

a

Explanation:

A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.

Channel and carrier proteins are both types of facilitated transport.

Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.

Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.

So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.

This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.

Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions.

When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.

Consequently, when an ion channel opens, the potential difference between the two compartments is altered.

Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.

The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.

This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:

Uniport, a single molecule translocates in only one direction.

Simporte, two molecules that translocate in the same direction.

Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

What happened if we add normal saline instead of PBS during beta amylase extraction?​

Answers

Answer:

hi

Explanation:

Saline is the solution of water and NaCl does not provide the appropriate pH, so enzyme activity is lost, we cannot add saline instead of PBS during beta amylase extraction.

How saline water affects beta amylase extraction?

PBS (phosphate buffer solution) is a type of buffer that is suited for beta-amylase activity, which implies that when beta-amylase is extracted using buffer, the enzyme's chemical activity is kept.

When we utilize saline, which is a solution of water and NaCl, the pH of the solution is not acceptable, and the enzymes' chemical activity is destroyed.

As a result, for enzyme/protein extraction, we always employ a buffer solution, which maintains the ph for the proper functioning of an enzyme.

Therefore due to pH conditions enzyme lost activity, and normal saline water can not be used instead of PBS for extraction of beta-amylase.
