You notice the line of mercury in your barometer is all the way to the top—30 inches. Is this high or low pressure? What kind of

Ket [755]

High altitude in the barometer indicates low pressure. This is also an indication of a bad weather like Storm. and inclement weather. A decreased altitude, however, indicates a calm and pleasant weather. So, in your case, a storm is coming.

Answer:

Milk weed It is an amazing plant we can see how it works against predators, which shows that it has a powerful natural protection complex. For example:

Explanation:

The E. helioscopy sap is intensely toxic, as protection against natural predators; It contains various esters of 12-deoxiforbol, of which the most concentrated and toxic is 12-deoxiforbol-13-phenylacetate-20-acetate. It causes an acute inflammation of the mucous membranes with which it comes into contact, and of the gastric membrane in the event of ingestion or blood absorption. It has been used experimentally in the pharmaceutical industry, and as a potential natural alternative for the production of gum in temperate regions where traditional sources cannot be cultivated.

In Indian medicine, its very toxicity makes it used topically and systemically as an anthelmintic, using the oil from the seeds and the decoction of leaves and stems.

5. It is difficult to diagnose genetic conditions because they are rarely seen and once problems start presenting themselves not only would a diagnosis need to be made. But to prove it you would have to take blood from both parents to see why they together could produce genetic conditions.
6) Down syndrome occurs when you get a smaller number of chromosomes you are supposed to inherit from each parent during conception.
7) a silent mutation is a change in DNA but does not changes the encoded and has no phenotypic effect therefore the genetic sequence is not changed

A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and the frequency of i allele is 0.5.

If:
$I^{A}$ - the frequency of IA allele
 $I^{B}$ - the frequency of IB allele
 $i$ - the frequency of i allele

Then:
 $I^{A} I^{A}$ + $I^{A} i$ - the frequency of individuals with A blood type
 $I^{B} I^{B}$ + $I^{B} i$ - the frequency of individuals with B blood type
 $ii$ - the frequency of individuals with O blood type

Let's first take a look on the Dunker population:
$I^{A} = 0.3$
$ii=0.16
$

Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.16}$
⇒ $i=0.4$

Now, we have the frequencies of two alleles ( $I^{A}$ and $i$ ). To calculate the frequency of $I^{B}$ allele, we will use the formula:
 $I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.3-0.4$
⇒ $I^{B} = 0.3$

Now, in the general population:
$I^{A} = 0.4$
$ii=0.25$

Similarly to the work for the Dunker population:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.25}$
⇒ $i=0.5$

$I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.4-0.5$
⇒ $I^{B} = 0.1$


b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.
