When antibiotics attacks a bacteria first the growth of bacteria is stopped and the bacteria will become unable to divide and spread throughout the body via the bloodstream and aortic arteries. An antibiotics' main job is to stop the growth of bacteria and other foreign entities inside our body, such as a virus, fungal spore, parasites, and other dangerous and potentially deadly protozoa, so as to prevent the body from harm that may be fatal.

On cellular level, antibiotics chemically damage the bacteria or targeted organism's DNA and alter it in such a way that they will become unable to divide any further and thus become unable to reproduce and eventually die off as the white blood cells engulf the decaying organism's body, so it doesn't become dangerous.

The amount of energy at trophic levels one and four in an ecosystem is indicated by the numbers.

nexus9112 [7]

Answer:

1100

Explanation:

There is 10% of total energy in each increasing trophic level. 10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.

1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.

1,000 + 100 units of combined energy would be 1,100 units of energy.

Hope this helps!

What do dna microarray assays allow scientists to study regarding gene expression?

Allisa [31]

DNA microarray assays allow scientists to identify networks of gene expression across an entire genome.

The microarray is scanned to determine the expression of each gene printed on the slide after hybridization. The associated spot on the microarray turns red if a particular gene's expression is higher in the experimental sample than in the reference sample.

The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2. The chip is made up of a tiny glass plate that is enclosed in plastic. A few businesses use techniques resembling those employed to create computer microchips to produce microarrays.
