Biological buffers usually work to keep pH in your body on a range of 1500 - 3000.
Answer:
Acid pH is <u>1</u> to <u>6</u>, base pH is <u>8</u> to <u>14</u>.
Explanation:
The pH scale ranges from 1 to 14 with 7 being neutral, 1 being the most acidic and 14 being the most alkaline. As you progress further to the left of the scale, substances get more acidic while moving to the right gives you substances that are more alkaline.
Hope this helps :)
Answer:
<h2>50%</h2>
Explanation:
As given;
A true breeding plant with purple flower: PP
A true breeding plant with white flower: pp
Cross between these parents = PP× pp
Offspring are =Pp, Pp, Pp, Pp( all are heterozygous purple)
Now cross between this plant and recessive white flower (pp)
Pp × pp
Offspring are: Pp, Pp, pp, pp
50% are white and 50 % are purple.
Look up your test statistic on the appropriate distribution- in case, on the standard normal (Z-) distribution ( see the following Z- table)
