In this lab, you used a variety of media with a NaCl concentrations ranging from 0.5% to 15%. On which of these media are the bacteria most likely to undergo osmotic lysis

Answers

Answer 1

Answer:

none of these media  

Explanation:

Bacteria have resilient cell walls composed of cross-linked peptidoglycan that acts as a cross-linked wire and thus prevents them from osmotic lysis. In consequence, bacteria are generally able to grow in hypo-osmotic conditions. Moreover, all the media indicated above are hypotonic compared to the bacterial cells, i.e., they have a lower solute concentration compared to the bacterial cytoplasm. In hypotonic media, bacteria can take up water from the external solution by osmosis.

What is an earthquake?

An earthquake is a sudden and intense shaking of the ground caused by the movement of tectonic plates in the Earth's crust. Earthquakes can result in damage to buildings, roads, and other structures, as well as cause landslides, tsunamis, and other natural disasters.

They are caused by the release of energy from tectonic plates as they shift and interact with one another. Earthquakes are measured on the Richter scale, which is used to determine their magnitude and potential for causing damage. The frequency and intensity of earthquakes can vary depending on location, with some areas experiencing more frequent or severe earthquakes than others.

2.) 19. Which of these processes is important in increasing genetic diversity in
organisms?


Answers

Answer:

its either meiosis or mitosis i cannot remember which though

Explanation:

The process that is important in increasing genetic diversity in organisms is meiosis, and in this process, the genetic diversity is seen due to the genetic crossing over and the recombination.

What makes meiosis important for the organism?

Meiosis is the process in which the parent cell makes the gametes that are haploid in nature; the male makes the sperm and the female makes the ovum in this process, and each of these gametes contains half of the genetic materials of the parent. Because meiosis results in genetic diversity in nature, it is important for the organism that produces offspring through sexual reproduction, and genetic diversity is seen in animals due to this process.

As a result, meiosis is an important process for increasing genetic diversity in organisms, and genetic diversity is visible during this process.
