The wells that contain the DNA samples are placed next to the negatively charged electrode in the electrophoresis box (chamber)
Katen [24]

Answer:

DNA is negatively charged

Explanation:

<u>Electrophoresis:</u> In biology, the term "electrophoresis" is described as one of the different laboratory technique that is being utilized to separate protein molecules, DNA, and RNA one the basis of their electrical charge and size. Therefore, a specific amount of "electric current" is being used to move different molecules that are required to be separated through a "gel". The given gel contains pores that generally works like a "sieve" and thus allows every small molecule to proceed faster as compared to the larger molecules.

<u>DNA</u> stands for<u> "deoxyribonucleic acid"</u> is determined as a long molecule that ought to contain an individual's unique "genetic code" and generally carried information associated for making proteins in an individual's body.

<u>In the question above, the correct answer is "DNA is negatively charged".</u>

Look at the data related to honey bee population losses between 2006 and 2013 (Figure 1). Expand on the data. How would you revi
olga_2 [115]

In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.

- Number of bee keepers over the period

The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.

- Area of trees suitable for the honey bees

The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.

- Pollution

The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.

Below are three different scenarios for comparison. For each scenario, decide if it represents greater or less entropy and great
uranmaximum [27]

Answer:

Entropy is characterized as a level of irregularity or disorder in a system. More the disorder more is the Entropy. The greatest entropy is accomplished when the system is in equilibrium.  

In a similar manner, stability is legitimately relative to entropy. Therefore, more entropy, more is the stability and the other way around.

<u>S.No      Scenarios                Entropy                  Stability </u>

A               Glucose                    Less                   Less

           Carbon dioxide or water      More                   More

B        A messy room              more                    More

               A clean room                      Less                     Less
