<u>Answer:</u>

<em>If Mendel crossed a true breeding dominant plant with a true breeding recessive plant the recessive trait is visible in the F3 generation. </em>

<u>Explanation:</u>

In <em>Mendel’s cross the selected parents are a tall pea plant and a short pea plant.</em> Tall is the dominant trait and short is the recessive trait.  Both the parents are homozygous.

Letter T represents tall and t represents short. Hence the phenotype TT is homozygous dominant and tt is homozygous recessive.  

<em>The genotype Tt represents tall since T is dominant over t. Mendel’s cross can be represented as  </em>

<em>Tall \times Short</em>

<em>TT \times tt</em>

<em>F1 generation      Tt     Tt   Tt   Tt </em>

<em>F2 generation     TT   Tt  Tt tt   </em>

garik1379 [7]

Answer:

The correct answer is option C.

Explanation:

The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.  

The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.  

These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.

Why does the word antibiotic suggest that these medications would be ineffective against viruses?
VashaNatasha [74]
Antibiotics are ineffective against viruses because viruses do not have cells. Viruses are infectious agents that live within the cells of other living things. Antibiotics work by breaking down the cell walls of bacteria or interfering with the bacteria's ability to repair its cell's DNA, according to How Stuff Works.
