Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.
Answer and Explanation:
Nondisjunction occurs when homologous chromosomes fail to segregate during anaphase I or sister chromatids fail to segregate during anaphase II. The result is an addition or loss of one or more chromosomes. Nondisjunction is associated with disorders like Down's syndrome due to an extra chromosome, Klinefelter's syndrome or Turner's syndrome. These phenomenon where one has three members of homologous chromosome is called trisomy.
This part of the experiment serves as basis of comparison; the one variable being tested has been omitted Experimental group.This part of the experiment shows the effect of the one variable being tested.Independent variable.This variable is an experiment is the one being deliberately changed by the scientist.
By means of natural selection.
I think natural could be the word
