In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.


The samples that were loaded into each of the four lanes are as follows:

Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested

Which of the following conclusions is most likely to be CORRECT?

A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid

Answers

Answer:

by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.

Explanation:

hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.

Imena is teaching her younger brother how to build a fire. As the fire sparks and starts to burn the kindling and wood in the fireplace, her
brother asks if the fire is alive because it is moving and growing. Imena tells her brother that the fire is not a living thing, and her brother asks
what makes something alive. What response does Imena give her brother?
250 words remaining

Answers

For something to be alive, it has to have essential characteristics. Some non-living elements share some of these characteristics with living things, but not all of them. That is what distinguishes one from the other.

The characteristics that all living things have are:

organization; sensitivity; growth; reproduction; homeostasis; and metabolism.

As regards organization, the minimum unit of life is the cell. For something to be a living thing, it has to be a cell or have multiple cells. They have organelles and organize to perform different actions.

The following characteristic is sensitivity, which means that the thing has to react to a stimulus by giving a response.

Living things grow. In other words, they increase in size thanks to the elements that they take from the exterior and process them taking what they need to grow. To do so, they use metabolism.

Metabolism is the combination of catabolism( the elements that the organism destroys) and anabolism( the elements that the organism builds). Metabolism is also essential for homeostasis. These are the different reactions that an organism has to have a balance.

The last essential characteristic is reproduction. Living things have to reproduce themselves, there are different methods, and they depend on the type of living thing that they are.

In conclusion, fire is not a living thing because it does not have cells that can have metabolism, sensitivity, homeostasis, and it can not reproduce itself.

A living thing has six main characteristics:

organization sensitivitygrowthreproduction homeostasis metabolism

Even though the fire seems like a living thing because it is consuming wood, making noises, and moving, as many living things do, it is not alive because it does not have cells. As it does not have cells, it can not have homeostasis, react to stimuli, or grow as cells do. It might look like a living thing, but it is not since it does not have the six characteristics that every living thing has.

Underground mining removes minerals from deep in the earth. Miners use blasting to separate the "waste" from the mineral deposit. Which statement best describes
an environmental consequence of this process?

O Underground mining activities often cause noise pollution

O Acid mine drainage kills plants and animals around the mine.

O High salinity of wastewater reduces soil fertility and vegetation

O Soil is removed by the force and pressure of the drilling process.

Answers

Answer:

Acid mine drainage kills plants and animals

Explanation:

took the quiz :)

The correct answer as to the environmental consequence of using blasting to separate wastes from mineral deposit is noise pollution. The statement that best describe the process, therefore, would be that underground mining activities often cause noise pollution.

Blasting simply means to break something apart or to blow up something. When blasting is associated with mining, it usually involves the use of explosives. These explosives make loud noise when they are used in blasting.

Hence, blasting can be said to be a source of noise pollution to those staying close to the mining area.

Which would be considered a reliable source?(1 point)

an opinion column in your favorite magazine


an article from a scientific journal

a blog written by an anonymous author


a biology textbook from 1920

Answers

When looking for updated and reliable information, you always need to point to scientific journals, magazines, encyclopedias, or textbooks recently printed or published. In the exposed example, the most reliable source is an article from a scientific journal.  

----------------------------------------

When looking for updated and reliable information, you need to be careful with the source, authors, and publishment dates.

In general, scientific journals, magazines, encyclopedias, or textbooks are sources of reliable information. The material exposed on these sources has been previously checked and evaluated by a group of people trained and capable to do so. If your favorite magazine is not a scientific one, you should look for another source.

You also want to consider the authors. Some researchers are very well known, and their publications probably reflect years of investigation. By looking for these authors´ publications you will ensure a good source. You should use a blog written by a well-known author, but not a blog that is written by an anonymous one.

You also need to consider that your source should be recently printed or published. Science is very dynamic and continuously changes. Discoveries always replace old information. So when looking for a reliable source, you need to look for recent publications. A biology textbook from 1990, although it is a reliable source, it probably has old information.
