The answer is A hope this helps
I think the correct answers are the half-life varies depending on the isotope, half-lives range from fractions of a second to billions of years and <span> half-life of a particular isotope is constant. Half-life is a constant value for a specific isotope that tells when does the mass of the isotope reduces to half of the original mass. Hope this helps.</span>
Mutations are more susceptible to natural selection in large populations, such as the bacterial ones. The bigger the population it is and the shorter the lifespan of the organism, the tougher is the competition between the individuals. So, even a small change, a mutation that enables its holder to have even slightly more chance to survive and reproduce makes a huge difference.
In addition, bacteria have prokaryotic cells that lack the DNA repair mechanisms and they are replicating more often than human cells with eucaryotic cells, which explains the higher rate of mutations in their genomes compared to human ones.
All organisms undergo some form of cellular respiration (bacteria, fungus, animal, plant ,)
Answer:
BMR ( Basal metabolic rate)
BMR may be defined as the energy required for the proper functioning of body at rest. This is the amount of energy required from the basal metabolism of the body. BMR is always less than TDEE. BMR of the body remains same in case of weight gain or weight loss.
TDEE ( Total daily energy expenditure)
TDEE may be defined as the daily energy expenditure of the body. The amount of energy requires from the physical activity and basal metabolism of the body. TDEE is always higher than the BMR. TDEE of the body may be affected by the weight gain or weight loss.
