Answer:
They are large macromolecules
Explanation:
Such as lipids, carbohydrates, proteins, or nucleic acids
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>
Answer:
Only 25% of the offspring will be homozygous dominant.
Genotype: 25% (FF), 50% (Ff), 25% (ff).
Phenotype: 75% red, 25% not red (other color probably)
Percentage: 25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive.
Explanation: Since your question does not mention for any letters, let's assume that F will be the trait for flowers. You can use any letter, so you can change it any time.
The Punnett square will look like this, since we mix two heterozygous red flowers (Ff + Ff)
FF Ff
Ff ff
The percentage that is homozygous dominant will be from the ones that only have F on them twice, which is only 1/4 or 25%.
