Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.

Why do bacteria only grow at certain temperatures?

  • The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
  • Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
  • An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

List the steps of how a squirrel hibernates.
hoa [83]

Answer:

1. First of all, a squirrel would make sure to stash lots of food before and during the winter.

2. The squirrel would claim its own tree hollow/burrow.

3. They wrap themselves into a tight ball and go into a state of torpor (Torpor is a state where their body temperature becomes about the same temperature as their surrounding hibernaculum. This causes their heart rate to slow and causes them to use less energy)

4. Squirrels get up after 20 or so days to rewarm themselves up, and perhaps eat something to regain their energy. After that they will head back to their hibernaculum to continue hibernation.

5. When spring approaches they will fully wake up, go eat, regain their energy, and prepare themselves for the mating season.

Hope this helps :)

Which of the following best describes the dust gas and celestial bodies of the Milky Way galaxy
Gnesinka [82]

The statement that best describes the dust gas and celestial bodies of the Milky Way galaxy is that -<u>They orbit around the center of the galaxy because of gravity.</u>

<u />

Explanation:

  • <u>The Milky way is referred  to as a spiral galaxy ,our sun,and all the planets are a part of this galaxy.</u>
  • <u />
  • <u>A galaxy is often said to be a large group of dust gas and celestial body (i.e nebula, stars, comets, meteors, asteroids, and planets.) bounded together with gravity.</u>

.

So we can say that the  statement that best describes the dust gas and celestial bodies of the Milky Way galaxy is that -<u>They orbit around the center of the galaxy because of gravity.</u>
