The Krebs cycle and electron transport chain take place in the inner membrane of the mitochondria, an organelle in the cell cytoplasm.
The mitochondria consists of an outer membrane, an inner membrane and a gel-like material called the matrix. The outer membrane covers the organelle like a skin. The inner membrane folds over many times and creates layered structures called cristae. It is where the Krebs cycle and the electron transport chain take place.
The folding of the inner membrane serve to increase surface area inside the mitochondria.
Over half the people who come here just want the answer, not the lesson they are avoiding. Mitochondria is the answer.
B. xylem.
C. transport tissue.
D. fibrous tissue.
Answer:
The pH scale has been drawn below.
Explanation:
pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.
Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.
Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:
Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.
Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.
Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.
So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).

b. It is rigid.
c. It is alive.
d. It stretches.gy
The best answer is b - it is rigid.
The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.
The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.
It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
the answer to this question is B because im doing a bilogy test right now as u read this :)

A) Inconsistent units of measure
B) Insufficient amount of data
C) Duration of the study
D) Number of samples
Answer: A. Inconsistent units of measure
Explanation:
When taking data such as measurements, it is very important that the results are reported in the same unit of measure. Failure to do so will eventually affect your analysed result.
Answer:
A) Inconsistent units of measure
Explanation:
Since Courtney measured the same variable in all the tagged tendrils, the unit of measurement is supposed to be the same. Before any further processing or analysis of the data, she will need to use the appropriate conversion factors to convert all the variates to the same unit.
The research lasted for a whole year and data were collected weekly, the issue of insufficient data or duration of study does not arise in this case. Also since, the size of study population was not indicated, it will be be difficult to point out the sample size as an issue.
The correct option is A.
Answer;
-Inhibitors
Chemical mechanisms that can turn off or reduce an enzyme are inhibitors.
Explanation;
-Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. They can bind to an enzyme and stop a substrate from entering the enzyme's active site and/or prevent the enzyme from catalyzing a chemical reaction.
-Enzyme inhibitors are classified as either competitive or non-competitive inhibitors. Competitive inhibition occurs when the substrate and a substance resembling the substrate are both added to the enzyme.
-Non-competitive inhibitors are considered to be substances which when added to the enzyme alter the enzyme in a way that it cannot accept the substrate.
