Answer:
When somewhere covered in mold you may not even see it, but a good way to know its there is the smell, or the quality of the air. If the air feels musky and gross there could be some mold somewhere.
False!
Starch is a polysaccharide. Monosaccharide is the basic unit of carbohydrates and it is a simple sugar. Polysaccharide is composed of a large number of monosaccharide units bound by glycosidic bonds.
Starch consists of a large number of units of <span>glucose</span>, a monosaccharide, units bound by glycosidic bonds. This suggests that starch must be a polysaccharide.
Answer: A. motion parallax
Explanation:
In the phenomenon of motion parallax, objects that are moving at certain speeds across a particular field of vision, would also appear to move at greater speeds if they’re closer to the observer. This remains true even if the object instead of the person is moving
. The phenomenon always arises whether or not the object is moving or that the observer is moving in a manner that is relative to the object’s motion. This is because of the distance the object moves in comparison to the proportion of the observers’ field of view that it traverses. Thus, motion parallax generally describes one’s perception of the position of an object with a three-dimensional space, based on sensing said objects at different positions.
Answer:
The options are
tapping the base of the pipette on the table
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
reading only the final volume of liquid after dispensing
ensuring that air bubbles are not in the column of liquid inside the pipette
The answer is
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
ensuring that air bubbles are not in the column of liquid inside the pipette.
Explanation:
A pipette is an instrument used in the laboratory for transporting and movement of liquid substances for various experiments. It is usually graduated to ensure accurate measurements of the liquid substance.
To ensure accurate reading of volume from a graduated pipette, precautions listed should be taken:
Using subtraction to determine the volume dispensed
Making sure that you read the volume with the liquid inside the pipette at eye level
Ensuring that air bubbles are not in the column of liquid inside the pipette.
Answer:
<em>Differences in air pressure, due to differences in elevation, trigger the development of different types of caterpillars.</em>
Explanation:
A hypothesis can be described as a tentative statement which can either be supported by evidence from experiments or it can be discarded if the results of an experiment do not support a hypothesis.
In the scenario, mentioned in the question, the air pressure had nothing to do with the different type of caterpillars being formed neither was it the focus of the experiment. Hence, the above mentioned hypothesis will not be supported by the experiments.
