Answer:
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between variables. The correlation coefficient is usually represented by the letter r.

Answer:
The correct matches are given as follows:
a. Amylase
- Starch
b. Pepsin
- Protein
c. Lipase- fats
Explanation:
The digestion can be defined as the breaking down of the complex compounds of food into simpler compounds for their better absorption. There are various enzyme that help in the process of digestion. Amylase, pepsin, and lipase are enzymes. The amylase is an enzyme responsible for breakdown of starch. The pepsin is responsible for the breakdown of protein into amino acids. The lipase is responsible for breakdown of fats.
Answer:
The correct answer: C) allows the behavior of microtubules called dynamic instability.
Explanation:
Microtubules are structures that are part of the cytoskeleton and help provide structure and shape to eukaryotic cells, besides assisting in the transport of organelles and vesicles.
Microtubules are formed by the polymerization of a dimer of two tubulins.
Microtubules have the particularity of being able to easily assemble and disassemble, which enlarges and shrinks the microtubule respectively. This property of the microtubules is important to their functions and is called dynamic instability.
In order to achieve dynamic instability, tubulin dimers can bind two molecules of GTP - for polymerization to happen, one of the GTP molecules is hydrolyzed to catalyze the reaction, thus becoming GDP. In the same matter, the energy generated from the depolymerization with turn the GDP into GTP.
