Answer:
For this specific star, it would be magnesium
Explanation:
when you look at the spectrum of light for, in this case, a star, you are seeing a specific light signature, like a fingerprint. you have to compare the black lines of the star's light spectrum to the light spectrum of different gasses to see which ones match up. in this case, the lines in star 8's spectrum match the lines in the spectrum of magnesium.
It is called Fluid Mosaic Model. It describes the structure of the plasma membrane as a mosaic component. The structures such as phospholipids, protein, carbohydrates and cholesterol gives the fluid like character of the plasma membrane.
Natural selection is when the more and better adapted organisms survive to reproduce and the weaker and less adapt die.
Answer:
P generation: 1 purple flower (AA) : 1 white flower (aa)
F1 generation: 4 purple flowers (Aa) : 0 white flowers
F2 generation: 3 purple flowers (AA, Aa) : 1 white flower
Explanation:
Assuming the parents are AA and aa, the allele for white flowers is recessive, so there needs to be two of them for the trait to be expressed. Thus, the capital A purple allele that the other parent contributes will mask that white allele and all the flowers will appear purple. However, all of the offspring are Aa now, so when they are crossed, there's a 25% chance that they'll both contribute the lowercase a allele that codes for white flowers. Remember that if both of them give the lowercase a allele then the offspring will be aa and appear white.
A is your answer I believe because they do indeed provide a way to review other scientists work and or experiments
