Answer:
Trial A is the blue line.
B is the orange line.
C is the green line.
The trial in which the disease spread the least was Trial C.
3 people never got the disease.
Explanation:
The more immune, the less the disease spread.
In Trial C, if 10 people were immune and 7 were infected and there were 20, then 3 never got infected.
The black fur is dominant over white(light) colour which means black fur trait only require one copy of allele to express itself.
Key
B=black
b=white
- Provided that the genetic cross is between genotype (BB) and (bb).
so, the probability that the offspring of this cross will have black fur is 100%.
2. Provided that the genetic cross is between genotype (Bb) and (bb).
so, the probability that the offspring of this cross will have black fur is 50%.
The right answer is A) Uses H2S for an energy source.
Beggiatoa is a bacterium that lives in sulphide-rich environments. They use H2S as a source of energy.
Purple sulfur bacteria, are also bacteria that depend on the presence of H2S but do not use it for the purpose of producing energy. They use it as the ultimate electron acceptor in its respiratory chain (instead of oxygen), since they are anaerobic bacteria.
I would say A. It would make the most sense.
Hope this helps!! and i know im a beginner but i know the answer
Convection currents are caused by the colliding of cold and warm air. At night, air above water is warm and air above land is cold. The opposite is true in daytime. When the warm air hits the cold air, which is more dense, it is pushed upward. Then it travels laterally until it cools. It comes back down and pushes up the former cold air, which is now warm. This repeats many times.
