Why is it important for the mass to be measured before measuring the volume.​

Biology
1 answer:
KiRa [710]3 years ago
6 0

Answer:

In this experiment the mass must be measured first because to determine volume water displacement is what is being measured. ... The reason for this is some solids will float on the water. Therefore the object's density is less dense than the water.

Explain why it is impossible for a man to be a carrier of a sex-linked trait.
hoa [83]

Answer:

Because it contains two different sex chromosomes

Explanation:

Man in its genome contains two sex chromosomes, X and Y, while woman contains two X chromosomes.

In order to be a carrier of a sex-linked trait, a person should have one copy (one allele) of a certain trait. For example, if a female has one X chromosome with mutation (e.g. disease carrying) and one normal X chromosome, she is carrier for the disease. But, on the other hand if a male has one X chromosome with mutation he will develop that disease.

Why do scientists need to study seismic waves to analyze the interior of the earth and the layers of the earth?
DaniilM [7]

Answer:

Answer 1:

Seismic waves, the waves of energy that travel through the Earth as a result of an earthquake can tell us a lot about the internal structure of the Earth because these waves travel at different speeds in different materials. There are two types of waves that travel through the Earth: p-waves and s-waves.

P- waves are faster and they can travel through both solids and liquids. S-waves are slower and cannot travel through liquids. For both kinds of waves, the speed at which the wave travels also depends on the properties of the material through which it is traveling.

Scientists are able to learn about Earth’s internal structure by measuring the arrival of seismic waves at stations around the world. For example, we know that Earth’s outer core is liquid because s-waves are not able to pass through it; when an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive. Similarly, we know that the earth has a solid inner core because some p-waves are reflected off the boundary between the inner core and the outer core. By measuring the time it takes for seismic waves to travel along many different paths through the earth, we can figure out the velocity structure of the earth. Abrupt changes in velocity with depth correspond to boundaries between different layers of the Earth composed of different materials.
