Define
n = number of seeds planted.
k = number of seeds that successfully become plants.

The probability of making a profit is
p =50% = 0.5
Therefore the probability of not makng a profit is
q = 1 - p = 0.5

According to the binomial distribution, the probability of k successes out of n trials is
$P(k \, of \, n) = _{n}C_{k}\,p^{k} q^{n-k} \\ where \\ _{n}C_{k} = \frac{n!}{k! (n-k)!}$

Create a table as shown below by using the graphing calculator.

n k P(k of n)
---- ----- ------------
4 2 0.375
8 4 0.273
10 5 0.246
12 6 0.226
16 8 0.196
20 10 0.176
50 25 0.0.112
100 50 0.08

A graph of this table shows that the probability of success i below 0.5 (50%) for all practical values of n (the number of seeds planted).

In 1918, the Russian Tsar Nicholas II was deposed, and he and his family were reportedly executed and buried in a shallow grave.

GaryK [48]

Answer:

By making a paternity test by Short tandem repeats, or STRs (microsatellites).

Explanation:

Short tandem repeats, or STRs, are microsatellites consisting of repeated sequences of 2 to 6 base pair length monomers in tandem, and most of them have a high degree of polymorphism. Half of an individual microsatellites are inherited by each parent, and they can be assesed by PCR amplification and further electrophoresis.

In this case, you would try to recover a bone from the remainings of the woman, the Tsar and his wife, since the rest of the latest were in a shallow grave with many different individuals. Preferably, you should manipulate this samples in an ancient DNA facility (aDNA) with proper techniques. You clean the bone samples, drill them, and from internal bone powder make a DNA extraction. After this, you perform a series of PCR targeting a panel of STRs, and electrophoresis. If the woman claim is true, half of her microsatellites should have correspondence with the Tsar, and half with the ones of his wife.

Which R group would most likely be found in a hydrophobic area of the tertiary structure of a globular protein?

Nataly_w [17]

Answer:

CH2-Aromatic ring

Explanation:

Amino acids with aromatic R groups are relatively hydrophobic and therefore don't interact with water molecules surrounding the protein. Tryptophan (Trp), phenylalanine (Phe) and tyrosine (Tyr) are amino acids with aromatic R groups. Since these amino acids are relatively nonpolar or hydrophobic, they participate in hydrophobic interactions that are strong when there are several residues with aromatic R groups which are stacked on one another. In this regard, it is also important to highlight that Tyr and Trp are more polar than Phe due to the hydroxyl (OH-) group in Tyr and the nitrogen in the Trp ring.
