Since there would be no red leaves the answer is B
It was commonly understood in the past the dogs come from a lineage of wolves, but that isn't the case now. Scientists have found out that dogs and wolves come from a common ancestor about 9,000 to 36,000 years ago. This was done through extensive DNA analysis with samples that took into consideration the geographic locations of their origin and of modern isolation. This yielded a result that despite geographical difference, the dogs are more closely related than to wolves. It is now understood that the complication of the genetic relationship between the two was caused mainly by interbreeding during the course of time, but it isn't just that. Some other factors have come into play including the presence of humans.
Answer:
<em>Here we see that there are three ways for an offspring to exhibit a dominant trait and one way for recessive. This means that there is a 75% probability that an offspring will have the dominant trait and a 25% probability that an offspring will have a recessive trait.</em>
Griffith experiment
Griffith used two types of bacteria in his experiment
1. R-type: it was non-virulent and cause no disease in mice
2. S-type: It was virulent and cause disease in mice which lead to death.
However when heat killed S-type was applied no disease was occurred in mice. Then he mixed heat killed S-type and live R-type and injected it into mice. He was expecting that no disease will be caused in mice.
Results
However, mice was died.
Conclusion
He was confused from this experiment. But later it was confirmed by other scientists that DNA from heat killed S-type was shifted to R-type. the progeny which formed from this transfer of DNA were virulent and cause the death of mice.
significance
It was concluded from this experiment that DNA is a hereditary material which transfer characters from parents to offspring.
At the molecular level, salt dissolves in water due to electrical charges and due to the fact that both water and salt compounds are polar, with positive and negative charges on opposite sides in the molecule. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.
