<h3>
Answer: C. a balance and a beaker</h3>
Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
B.
Asbestos was used in housing for many years because it was cheap to manufacture and was amazingly heat-resistant, but was found to be incredibly dangerous, causing innumerous accounts of lung cancer and related problems.
This is from memory, but I will double check after I answer.
Answer:
The sugar molecules in the marshmallow are being changed into carbon. Sugar can be changed into water molecules. When you toast marshmallows, the heat causes a chemical reaction producing water molecules which then evaporate, leaving the carbon behind.
Explanation:
Answer: The color would be light red
Explanation:
Apple juice is derived from apples which are rich in vitamin C. Chemically, vitamin C is an acid called ascorbic acid and apple juice also contain acids like folic acid and Pantothenic acid.
Hence, it is to be considered as acidic in nature.
So that, pH of apple juice is found to be in the range of 2.9 - 3.5.
Hence, the Colour of pH will be Light Red
The given statement "Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another." is False.
<h3>
What is gene flow?</h3>
- Gene flow refers to the processes by which genes are transferred from one group to another.
- Gene flow, which is a term used more frequently in anthropology, refers to the allelic change brought on by human movement.
- Gene flow would reduce the isolation that could lead to speciation by increasing population similarity and reproductive kinship.
- Gene flow significantly slows down speciation by recombining the gene pools of the groups and therefore repairing the growing variations in genetic variation that would have otherwise resulted in full speciation and the creation of daughter species.
