Answer:
The gene that controls production of white blood cells.
Explanation:Gene expression within the body is controlled by the cells, which determine when a specific gene should or should not be expressed. Influenza (the flu) is caused by a virus that attacks the respiratory system
Answer:
Mitocondria is responsible for the reactions in cellular respiration.
Explanation:
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.
False. Plants play a huge role in shaping the environment and ecosystem.
I'm not sure what the answer choices are, exactly, but looking up the question I found several other questions with answers, so I'm guessing based on those the choices would be:
1) physical barrier within population
2) extensive gene flow
3) chromosomal changes within population.
Which, in this case, the answer would most likely be 3) chromosomal changes within population.
