Hi!
The correct option would be A) Mendel’s genetics states laws that are now part of the theory of biological evolution.
When Darwin proposed the idea of biological evolution, which revolved around the concept that favorable genes are naturally selected into a species to ensure survival, his theory was criticized as during that time there was the idea that individual traits of two parents would present themselves as a blend in the offspring.
Gregor Mendel's theory of inheritance supported Darwin's idea as it dealt with the transmission of traits in generations through entities called genes, which were present in pairs for a particular trait.
Hope this helps!
Answer:
The star is moving toward us
Explanation:
The wavelength of a distant object changes due to the change in the distance between the observer and the object. This is known as the Doppler effect.
If the wavelength decreases this means that the wavelength in going towards blue which is shorter wavelength. This is known as blue shift. If blue shift occurs then it means that the object is coming closer to the observer.
Hence, the star described here has blue shifted and is moving closer to us.
