Answer: 1. Disaccharide
2. two monosaccharides, galactose and glucose
3. the role of lactase is to catalyse the hydrolysis of the disaccharide lactose to yield the monosaccharides galactose and glucose
Explanation:
Lactose is a disaccharide, consisting of two monosaccharide units joined by a beta 1–>4 glycoside link
Lactase cleaves the glycoside link, giving two monosaccharides, galactose and glucose
Question: Which phrase defines a law?
A. a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable
B. A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
C. a hypothesis or group of related hypotheses that can be accepted as true based on repeated experimentation with similar results
Answer:
Correct answer: B). A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
Explanation:
A scientific law may be defined as the something that appears to be true and is universally applicable. Scientific laws do not explain why the observed events happen, but it only states that the event occurs in the same way over and over. Example of scientific law is a law of gravity. Gravity is always there and it always works in the same manner. Other examples include newton's law of motion, which states how the things move.
The entire ecosystem.
It is important because any waste in a lake/water system can be harmful to the wild life. An example is trash like plastic bottles, cans, plastic bags, and oil.

Mitosis is split into 4 phases.
P - prophase
M - metaphase
A - anaphase
T - telophase
During Metaphase, Chromosomes align singly along the metaphase plate.
During Anaphase, kinetochore microtubules shortens and non-kinetochore microtubules lengthens, allowing the chromosomes' centromeres to separate.
Therefore, the answer is anaphase.
P. S. centromeres separates, not split.
