For this experiment, artificial selection is made by the scientists where traits of benefit are made to be present in the gene by high mutation rate so that the adaptability increases.
Explanation:
Natural selection is a process by which a organism with beneficial traits survive and reproduce in large numbers. They adapt to the environment very quickly and pass on these traits to its progeny which are at the better survival zone.
The mutations for the beneficial traits in certain genes caused the bugs to adapt to their environment well. When mated, they pass on the traits in every generation. It is also said that those organisms who did not get mutated eventually died.
The faster the mutation rate, the faster the mutated bugs with beneficial traits will appear in each generation.
From the graph it can be said that those bugs who could not bear the mutation they died and hence did not appear in the next generation only those bugs who could cope up the environment survived.
Answer:
Each compartment contains a bundle of muscle fibers. Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium. Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.
Explanation:
Answer:
The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".
Explanation:
A chemical change is one which is not easily reversible and which results in the formation of new subsatances.
For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.
From explanations provided by the students :
Luke does not give any explanation of the process but only an observation
Jackie's explanation does not state the main reason why a chemical change differs from a physical one.
Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.
Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.
Since there would be no red leaves the answer is B
