What else can I help you with?
How does a cell control movement of substances into and out of it. Explain with an example?
One way is by active transport. The sodium-potassium pump is one example of this. Yo keep the interior of the membrane negative and the exterior positive, plus using this method in neural transmissions. the pump pumps out three sodium ions and brings into the cell two potassium ions using the energy of ATP.
Which method does potassium enter the cell?
Special sites on the cell unlock to allow the glucose to enter. This is triggered by the presence of a chemical called insulin.
What method of transport is required when molecules must be moved against the concentration gradient?
There are multiple ways for cells to transport things across a difference in concentration. The most common process is diffusion, which is the movement from high concentration to low. Osmosis is the most popular example of this. Facilitated Diffusion is basically diffusion with the use of proteins that are specified for certain molecules. Active Transport is the method by which molecules are transported from low concentration to high concentration.
Explain the hittorf and moving boundary method for determination of transport number?
The Hittorf method involves measuring the change in concentration of each ion at the electrode before and after electrolysis to determine the transport number. The moving boundary method tracks the movement of ions within a solution during electrolysis using techniques like capillary electrophoresis to determine transport numbers. Both methods provide insights into the efficiency of individual ions in carrying charge through the solution.
One method used to classify protozoa is by their method of?
One method used to classify protozoa is by their method of locomotion. This can include cilia, flagella, or pseudopodia movement.

What is the Method of movement that requires the expenditure of ATP molecules is?
The movement that requires the expenditure of ATP molecules is called active transport. In active transport, cells use ATP to move molecules or ions against their concentration gradient, ensuring that specific substances are taken up or expelled from the cell as needed. This process is essential for maintaining cellular functions and homeostasis.
What is the chemical formula of potassium sulphate in criss-cross method?
The chemical formula of potassium sulfate using the criss-cross method is K2SO4. This method involves swapping the numerical values of the charges on the ions to determine the subscripts in the compound.
What is the function of Point -to- Ponit protocol?
To determine a method of encapsulating data and transport packets between two devices in a network

Which steam-powered method of transport quicky out placed transport by canal?
train
Which transport is the best to use between rail transort and road transport?
Rail transport is more efficient and clean. It requires less investment to install the tracks. This was a preferred method compared to paving and installing roads for some time in the past.

What is the principle of the cyanmethemoglobin method?
Colorimetric method where blood is mixed with solution containing potassium ferricyanide and potassium cyanide. Potassium ferricyanide oxidizes iron to form methemoglobin and potassium cyanide then combines with methemoglobin to form cyanmethemoglobin.
What is the formula of potassium chloride by crisscross method?
The formula for potassium chloride is KCl. In the crisscross method, you simply cross the numerical charges of the ions to determine the subscripts in the formula. For potassium chloride, the +1 charge of the potassium ion (K+) crosses over to become the subscript for chloride (Cl-), resulting in KCl.
