If Noam chooses a filter, it might be more effective than a screen. After using it for a while, though, he will have to replace it, which could be expensive. A screen might be less effective, but it can be cleaned instead of being replaced.

An advantage of a filter is it cleans the water better then the screen
A disadvantage is that you need to wash and sometimes fix the filter

Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning with by constructing a mathemat
scoray [572]

Answer:

Since the gene mutates at a rate of 0.76 base pairs every 17.1 million years, to find out the time it would take for 1 base pair to mutate can be calculated by dividing 17.1 million years by 0.76

17,100,000 ÷ 0.76 = 22.5 million years

The following equation can be used to describe this:

μ = [(r2/N2) − (r1/N1)] × ln (N2/N1) = (f1 − f2) × ln (N2/N1)

r1 = the observed number of mutants at time point 1

r2 = the observed number of mutants at the next time point

N1 and N2 are the numbers of cells at time points 1 and 2

Waat phenotype has the greatest frequency in a trait that follows a normal distribution
Neporo4naja [7]

Answer:

A phenotype is the physical observations of anything, really. For example, lazuli bunting (a bird species) has feathers that range from dull brown to bright blue. the dull brown and bright blue birds are best at mating. adult males are aggressive toward the bluish-brown birds. The greatest frequency here is that 2 seperate colors are able to mate best, yet, the mixed birds are attacked.

Explanation:

I hope this helped,

Which of the following choices correctly matches a tool and its proper application?
Alecsey [184]

Answer:

The correct answer is option A. "cell fractionation to study the function of specific organelles".

Explanation:

Cell fractionation is a scientific process used to study the function of specific organelles, which main idea is to fractionate the cells but preserving the individual function of the elements of the cell. Usually, the separation takes place by a centrifugation method. This methodology was developed to identify the location of the organelles within the cells, but nowadays is used to study its functions.
