Cell membrane is semi-permeable outer covering of an animal cell. Cell membrane allows the transport of substance into and out of the cell. When the spinach and lettuce are placed in water they become firm and crisp due to endo-osmosis of water.

A cell membrane is the outermost covering in the animal cell and it is covered by the cell wall in the plant cells. Cell membrane is responsible for the transport of materials into and out of the cell.

Cell membrane is semi-permeable in nature that means it only allows some substances to pass through the membrane and block others. Osmosis and diffusion are the processes through which substance pass. When a cell is placed in water, the concentration of water is low inside the cell as compared to the solution. In this case, water travels from its high concentration to its low concentration into the plant cell and the leaves swell and become crisp.

3. Independent variable: C) The species

4. Things to be done to improve this experiment: G) Add a control group; include more subjects, humans and more dogs of the same breed; increase the length of time the experiment is conducted.

5. Extraneous variables: F) The dog might not let her be measured. Different human hairs grow at different rates; this is not accounted for.

6. Ways to perform the experiment: E) Size of shaved patch; length of time hair grows

7. Controlled variables: A) what is the effect of species on hair growth?

1. The dependent variable is what is being measured or observed in an experiment. In this case, it is the length of hair or the amount of hair growth in both Isabelle and her dog's shaved patches.

2. This is the problem question, which outlines the main focus of the experiment - to determine the impact of species (human vs. dog) on hair growth.

3. The independent variable is the factor being manipulated or changed in an experiment. Here, it is the species - either human or dog - which may influence hair growth.

4. These are ways to improve the experiment. A control group provides a baseline for comparison, increasing subjects ensures more reliable results, and extending the experiment's duration may reveal more accurate trends.

5. These are extraneous variables, which are uncontrolled factors that could affect the experiment's outcome. The dog's behavior and variation in human hair growth rates could introduce uncertainties.

6. This describes the procedure for conducting the experiment, outlining the steps taken to measure hair growth.

7. These are controlled variables. The size of the shaved patch and the length of time hair grows are constants intentionally kept the same to isolate the effect of the independent variable (species) on the dependent variable (hair growth).

The liver is a vital organ as it secretes one of the most important enzyme- Bile.

Bile aids in digestion by breaking down fats in the small intestine and carrying waste away, making specific proteins for blood plasma. Cholesterol and unique proteins are produced to assist the body in transporting fats. The liver's special ability to produce bile is essential to the organism's existence. Recent advances in the understanding of the mechanism underlying bile production have laid the groundwork for improved diagnosis and management of cholestatic diseases.

Hepatocytes produce bile, an intricate aqueous secretion that is altered distally by absorptive and secretory transport systems in the bile duct epithelium. After that, bile either travels directly to the intestinal lumen or is concentrated in the gallbladder. A number of endogenous solid elements, such as bile salts, bilirubin phospholipid, cholesterol, amino acids, steroids, enzymes, porphyrins, vitamins, and heavy metals, as well as exogenous medicines, xenobiotics, and environmental pollutants, are dissolved in bile's approximately 95% water content.

High salt concentrations in soil is plants that appear dehydrated even when they are receiving adequate water because the salts comes from the irrigation activity.

The more salt that accumulates in the soil from irrigation and natural occurrence in the soil. We applied water to the plants in order to maintain the water content in the plants and make them hydrated. Sometimes the water has high salt concentration that negatively affected plant growth. Salinity greatly affects production in crops and trees by preventing the nitrogen uptake, reducing the growth and also stop the reproduction process in plant. Chloride salts are the toxic ion to plants. When its concentration increases in the soil, the plant is poisoned and dies in the end.

Fructose  found naturally in fruits and honey, must be changed into glucose in the liver before it can be assimilated by the cells of the body​

From the digestive tract, monosaccharides, glucose, galactose, and fructose are eagerly absorbed by the liver, where they can be used to produce glycogen or to provide the body with the immediate energy it needs.

About 15–25% of the glucose that is consumed by healthy human individuals is processed in the gut and liver, where it is mostly utilised to replenish hepatic glycogen reserves.In the liver, glucose is phosphorylated to become glucose-6-phophate.

A kind of sugar called a monosaccharide contains fructose. Like other sugars, fructose has four calories per gramme. Fructose is sometimes referred to as "fruit sugar" since it is mostly naturally present in many fruits.
