<span>A liquid that can easily pass through cell membranes is water. That is what is used in determining the concentration of the solute inside a living cell. You can place the cells in different osmotic environments. Then you observe and determine the environment that causes no uptake of water.</span>
Answer:
D) K being transported out of the guard cell.
Explanation:
The movement of water in the terrestrial plants is a very important factor as each cell of the plant require water to survive.
The movement of water is influenced by many physical, chemical and process going on in the plants like transpiration and stomatal opening and closing.
Water posses adhesion and cohesion properties which allow the water molecules to form a bond with other surface and with each other respectively. This allows the movement of water in the xylem by a process called capillary action.
The evaporation of water creates a pressure on the plant to absorb water from the soil but when potassium ions move out of the guard cell of stomata, the guard cells lose turgidity and stomata gets closed.
Thus, Option-D is correct.
<span>The metabolic activity of a specific region of the living rat brain can be revealed by measurement of Fos protein concentration.
c-Fos is a proto-oncogene that is the homolog of the retroviral oncogene v-fos. It was first discovered in rat fibroblasts as the transforming gene of the FBJ MSV.</span>
Explanation:
kidney dialysis is when a person is experiencing kidney failure.
it is needed when the kidney don't filtrate blood the way it used to do, so a person will have to go to the doctor and wait for hours so they can have their blood filtrate. it's bad and could lead to death.

Answer:
- Pol III binds to 3' end of primer B
- Poll III moves to 5' to 3',adding DNA nucleotides to primer B
- Pol I binds to 5' end primer A
- Pol I replaces primer A with DNA
- DNA ligase links fragments A and B
Explanation:
Both strands of parental DNA acts as a template for the synthesis of new DNA. The site of synthesis is called replication fork because the daughter strands look similar to <em>two-pronged fork.</em> The strands formed from Okazaki fragments(short sequences of DNA nucleotides) is called the <u>lagging strands,</u> which is synthesized in short fragments and in the opposite direction. While the strand that is synthesized continuously and in the same direction as the movement of the replication fork is called the <u>leading strand.</u> Both strands are synthesized in a 5'→3' direction. DNA ligase join these fragments together.
