Answer:
A. It Shows that organisms have changed over time.
Explanation:
The offspring will have one allele for straight wings and one allele for curly wings.
Explanation:
Let W be straight wings (big letter for dominant allele)
Let w be curly wings (small letter for recessive allele)
Each fly has two alleles.
If a parent is true breeding, it only has one type of allele.
Parent 1 = WW (straight wings)
Parent 2 = ww (curly wings)
Cross the parents: WW x ww in a Punnett square (see photo below)
This is the F1 generation (generation produced by crossing the first parents).
There are only Ww offspring.
Therefore,
The offspring will have one allele for straight wings and one allele for curly wings.

All of the above are True
- Part of the Bohr model proposed that electrons in the hydrogen atom are located in "stationary states" or particular orbits around the nucleus.
- An orbital is the volume in which we are most likely to find an electron.
- The uncertainty principle states that we can never know both the exact location and speed of an electron.
- The emission spectrum of a particular element is always the same and can be used to identify the element.

Answer:
The African savanna ecosystem is a tropical grassland with warm temperatures year-round and with its highest seasonal rainfall in the summer. The savanna is characterized by grasses and small or dispersed trees that do not form a closed canopy, allowing sunlight to reach the ground. The African savanna contains a diverse community of organisms that interact to form a complex food web.
