The statement which best explains the presence of carbon 14 in organisms is this: THE RADIOACTIVE ISOTOPE REACTS IN THE SAME WAY AS THE STABLE ISOTOPES IN THE CHEMICAL REACTIONS IN THE BODY.
The radio active carbon 14 that is found in living organism react in the same way that other carbon isotopes react and does not have any damaging effect on the body.
The answer is cornea…..lens. Most bending of light entering
the eye is bent by the cornea. The lens of the other hand adjusts this bending
further, to focus it squarely on the retina. This is why the focal point of the
lens can be adjusted by changing its shape.
Populations have a genetic variation among individuals and that is important to the populations ability to survive in different situations that have an affect on the natural selection. There are different factors which can increase or decrease the genetic diversity, and influencing natural selection. These factors can include an environmental factor, one of the major factors, which can cause changes in the genetic variation of a population and influence the natural selection. A famous and important example of the environmental factors affecting natural selection was made during the industrial revolution when many more gray moths made up the moth population. This was so that they could blend in with the soot from factories to avoid predators.
The answer is lag. The number of bacterial cells doubles at a constant, exponential rate during log phase, while growth rate and death rate are the same during stationary phase. The fourth phase is the death phase, when the rate of cell death is faster than the population growth.
Answer:
No, the lack of short-tailed animals in the sample does not suggest that the population is out of Hardy-Weinberg equilibrium in this forest. It probably means that individuals with short tails were not included in the sample by chance, as their expected frequency in the population is considerably low.
