Answer:
A. Multiple allele because a trait is controlled by three different genes
Explanation:
Multiple allele because a trait is controlled by three different genes
polygenic because the offspring have alleles from both parents
multiple allele because the offspring have alleles from both parents
polygenic because a trait is controlled by three different genes
Fats must be broken down into fatty acids before being converted into glucose. Lipids are known as the back up energy source. They are used to make enzymes, hormones, and antibodies.
U just check a few of them and pretty much close the app then they should be cleared :)
Answer:
The high specific heat of water caused by hydrogen bonding
Explanation:
Specific heat capacity of a substance is the quantity of heat required to raise the temperature of a unit mass of that substance by one degree Celsius (1° C).
Due to the hydrogen bonding present in water, water has a high specific heat capacity of 4184 Joules per kilogram. This means that, water has to absorb 4,184 Joules of heat for the temperature of one kilogram of water to increase 1°C. When compared to other substances such as metals, this is very high. For example, the specific heat capacity of copper is 385 Joules per kilogram which means that it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
Therefore water, can absorb a large quantity of heat with very little changes in its temperature. This property of water helps the oceans and seas to serve as heat reservoirs by absorbing a large quantity of heat in hotter seasons and releasing these heat in colder seasons.
a. What is a star's spectrum?
A star's spectrum refers to the <em>"amount of light"</em> that stars they give off according to varying wavelengths. Since we cannot tell the amount of light a star gives off quantitatively from Earth, we can differentiate them according to how bright they appear.
b. Which spectrum is most common in stars?
Stars are classified according to their spectra <em>(elements in the star)</em>. They are classified into 7 types <em>(O, B, A, F, G, K and O). </em>The most common type is M, however, it gives off a dim light.
c. How can it differ from start to star?
Although stars follow a continuous spectrum, the spectra of a star differs from each other because <u>they do not give off the same amount of energy at the different wavelengths. </u>
d. What does the spectrum tell us about the star?
The spectrum can tell the<em> surface temperature</em> of the star. This means that a blue star (we often see it as a white-colored star from Earth) is hotter than that of a yellow star. A red star is considered the coolest star among all.
The spectrum of stars also allows the astronomers to study composition of the stars according to their <em>wavelengths.</em>
