What happens during the lytic cycle of a viral infection?
mina [271]
1) Bacteriophage injects its DNA into the host cell
2) The DNA circularises
3) Viral gene activates the host cell's DNA synthetic machinery
4) Rapid reproduction of viral DNA occurs
5) Host makes viral capsomeres, allowing viral assembly to take place
6) Due to the large volume of new bacteriophages inside the host cell, the cell splits (cell lysis), releasing the new bacteriophages

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4,
12345 [234]

Hey there! :)

Answer:

The 3rd choice. a = -4, b = 5, c = -2.

Explanation:

Rearrange the quadratic equation given into the form 0 = ax² + bx + c:

0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2

The corresponding coefficients for the a, b and c values are:

a = -4

b = 5

c = -2.

If you allowed your dilution tubes to incubate for 24 hours before plating them on the TSA agar plates, do you think the results
Andreyy89

Answer:

The TSA or the tryptic soy agar is formed of casein and soybean meal, this formation helps in the appropriate growth of a huge array of non-fastidious and fastidious microbes. This combination of soy and casein provides organic nitrogen in the form of polypeptides and amino acids, which makes the medium more suitable for growth.  

In the given case, if one permits the incubation of the dilution tubes for 24 hours prior to plating them on the TSA agar plates than there is a more probability of the result to get affected. As if unlimited resources are already present in the tubes, it will provide more favorable conditions for the formation of more colonies and thus will influence or change the colony-forming units per milliliter.  

Even if the dilution is performed in a hood and in an autoclaved medium then also there will be an increase in the colonies of the microbes as in the time of 24 hours interval more microbes will get differentiated and will increase in number.

Leya [2.2K]

Answer: Protists

Explanation:

The protists are organisms which have characteristics similar to both plants and animals. There is huge diversity of protists on earth as they are single celled organisms and they increase in numbers by reproduction. They have a specialized cellular structure which includes organelles like nucleus, mitochondria, and others which are characteristic features of the eukaryotic organisms. They live in moist environment. They engulf their prey this way they are heterotrophic and they can also photosynthesize like plants.
