The right answer is A.

The term "hormonally active agent" (or endocrine disruptor) refers to any molecule or compound chemical agent, xenobiotic having hormono-mimetic properties and described as a cause of physiological abnormalities, and in particular reproductive abnormalities. Some examples are PCB, TCDD, DDT. Some of them were used as pesticides and are now banned for use. Their traces always exist at the soil level due to their persistence.

These agents are most often associated with breast cancer.

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>

Which factors affect the rate of deposition? Check all that apply. color of the sediment density of the sediment size of the sed
MakcuM [25]

Answer:

density of the sediment

size of the sediment

velocity of the agent of erosion

Explanation:

Deposition can be defined as the process of building up of sediment from chemical processes because the forces which are responsible for transporting Sediment are no longer sufficient enough to overcome the forces of gravity which is why density of the sediment, size of the sediment as well as velocity of the agent of erosion tend to affect

The rate of deposition due to the fact that

Larger and denser particles are heavier and land first before, less dense particles which cause round pieces of sediment settle more quickly than flat pieces .

Hence,density of the sediment,size of the sediment as well as velocity of the agent of erosion will often affect the rate deposition.
