Answer:
The correct option is <em>B) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.</em>
Explanation:
Organism of a population might have genetic variations in them due to many reasons. The species of a population which are better adapted to live in a particular area are able to survive and produce more offsprings. As a result, that particular area increases in that genetic variant.
In the above scenario, some of the wolves had variants in their digestion which made them better adapted to live with the humans as they could eat wheat, rice etc. The wolves which did not have variants in their digestion couldn't survive in the human areas.
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. The process is simple. Your body obtains oxygen from the ambient air you breathe. It enters the blood stream and is carried to your muscles, where some of it is used immediately, and the rest is stored by a compound called myoglobin. Whether you’re exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP.
Answer:
<h2>b) 640,000</h2>
Explanation:
Given:
Initial population = 10,000
Doubling time= 20 minutes
total culture allowed time = 2 hours
after 2 hours final bacterial population is 640,000
calculation:
10,000 doubles after 20 minutes = 20,000 and so on... final population after 2 hours = 640,000.
