Answer:

The salt pulls water out of the slug in light of the fact that the NaCl breaks separated into two particles (negative and positive charge) and this declines the water potential on the outside of the slug.

Explanation:

The proportion of the overall propensity of water to move starting with one zone then onto the next, and is regularly spoken to by the Greek letter Ψ (Psi). The salt pulls water out of the slug in light of the fact that the NaCl breaks separated into two particles (negative and positive charge) and this declines the water potential on the outside of the slug.

Organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to

Vaselesa [24]

The statement that organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to their offspring is false. Organisms pass their traits and adaptation abilities to their offspring. These organisms have also characteristics that are advantageous for reproduction in a specific environment and leave more offspring in the next generation. The process is called natural selection.

On your first attempt to run a PCR, you realize you forgot to add one of the two primers. The graduate student you work with sug

dem82 [27]

Explanation:

During PCR, we use two primers one is forward primer and the other one is reverse primer they match the sequence of one one of the two complementary strands of the target DNA, they flank the target region (that the region which we has to be copied). if we add only one primer it copies only one strand of the DNA in multiple copies. Usually we call this as Asymmetric PCR.

Generally Primers are synthetic short stretch of oligonucleotides that are complementary to the target DNA. They act as a foundation for the amplification process of DNA to form multiple copies

Two autosomal genes, J and K, are 60 map units apart. You perform the following testcross: J K / j k x j k / j k. At what freque

Dmitry [639]

Answer:

J K / j k = 20%

j k / j k = 20%

J k / j k = 30%

j K / j k = 30%

Explanation:

To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.

The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.

So, en the exposed example:

J and K are autosomal genes

J and K are separated by 60 M.U.

60 M.U. means that there is 60% of recombination.

Cross) J K / j k x j k / j k

Gametes) JK Parental jk, jk, jk, jk

jk Parental

Jk Recombinant

jK Recombinant

One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.

1 M.U. -------------- 1% recombination

60 M.U. ------------ 60% recombination

30% Jk + 30% jK

100 M.U. - 60 M.U. = 40 M.U.

40M.U.--------------40 % Parental (Not recombinant)

20% JK + 20% jk

Punnet Square) JK jk Jk jK

jk JK/jk jk/jk Jk/jk jK/jk

J K / j k = 20%

j k / j k = 20%

J k / j k = 30%

j K / j k = 30%
