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>

mixer [17]

Answer:

(08) and (32)

Explanation:

To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.

The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.

IRISSAK [1]

Answer: E. Polygenic

Explanation: The color of eyes and hair is due to quantity and accumulation of pigments such melanin. Melanin is synthesize by multiple enzymatic steps and every enzyme is codified by a different gene. That means polygenic inheritance, that several genes are implicated in determined the this trait and its difficult to trace since every gene has a sequence that can vary between families or human groups.

Which statement best describes the relationship between proteins and nucleic acids?
Iteru [2.4K]
Although the options are not provided, the statement best describing the relationship is nucleic acids provide blueprints for the construction of proteins.
Messenger RNA molecules (mRNA) take instructions from DNA molecules and take the code out of the nucleus. There, ribosomes work with the RNA molecules to produce a chain of amino acids, which in turn links and folds in a specific manner to form a protein molecule.
