Answer:
Different mass
Different volume
Same density
Explanation:
Intensive physical properties are those properties of a substance that is not dependent on amount i.e. do not change in response to changes in the amount of the substance. Intensive properties include density, temperature, boiling point etc.
On the other hand, extensive properties are those properties that are dependent on the amount of the substance. For example, mass and volume are extensive properties.
Hence, according to this question, measuring an entire bar of soap and comparing it to a piece of soap, the bar and the piece would have a:
- Different mass ( size dependent)
- Different volume (size dependent)
- Same density (size independent)
Answer:
c) melatonin
Explanation:
Melatonin its a hormone formed by the pineal gland, which regulates an individual wake cycles and sleep. Jetlag alters the hormone function leading to an alteration with the body clock of the persom.
Jetlag is a sleep disorder common to those who travel swiftly over several time zones. It is not a permanent sleep disorder. Its due to the body's internal clock lacking sync with cues generated in a different time zone, Cues may be due to light exposure and how often the person eats.
A basic factor on ones internal clock is sunlight. It controls the regulation of melatonin which aid in synchronizing cells in the body.
Specific cells of the tissue at retina moves the light signals the thypothalamus.
At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.
This question has a two part answer. The first part is that an asteroid hitting the earth and the second part is massive volcanoes erupting around the world.
Hey there!

~Scales
These three things normally tend to only be on fish. However, reptiles may have some of these characteristics as well.
Hope this helps!

Answer: One parent is IAi and the other parent is IBi
Explanation: As this trait is codominant, the child can inherited IA, IB or i.
Tina has type O, which means she is ii and her sister is AB, so her genotype is IAIB. Now, to have a child with a recessive trait both parents has to carry at least one allele for the recessive, i. Rosa is type AB which means she had to have inherited one allele IA from one of her parents and the other IB from the other parent. Thus, one parent is IAi and the other is IBi.
