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.

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.

Explanation:
All living things are characterized by their ability to grow, reproduce, use energy by respiration, respond to stimuli, and easily adapt to their environments. When a living thing loses the ability to perform all of these basic functions, then it can be said to be non-living, or dead.
In addition, locomotion, excretion, metabolism, and nutrition were all exhibited when dead things were once alive.

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.

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
Listen How are channel and carrier proteins similar? Select all that apply.
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
B. Channel and carrier proteins are both types of facilitated transport.
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.

placing 10 mice next to a microwave for 10 seconds. He compared these 10 mice to
another 10 mice that had not been exposed. His test consisted of a heavy block of wood
that blocked the mouse food. He found that 8 out of 10 microwaved mice were able to
push the block away. 7 out of 10 of the non-microwaved mice were able to do the same.
