Based on your experimental results, categorize each microbe as preferring isotonic environments, being halotolerant, or as a hal

ophile.

NISA [10]3 years ago

The microbes present in the experiment were:

S. cerevisiae

S. epidermis

A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.

If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:

  • S. cerevisiae only grows when it is in a 1% solution.
  • S. epidermis only grows when it is in a 1% and 7% solution.

In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

QUESTION 1: The term "Central Dogma" was first proposed in 1958 by Francis Crick, discoverer of the structure of DNA, to describ
Vera_Pavlovna [14]

Explanation:

Central dogma represents the pathway in which the information encoded in the DNA flows into proteins.

The DNA is made up of the nucleotide monomers in which the nitrogenous bases are present as one of the constituents. These bases are present in the sequence are transcribed into the RNA molecule through the process of transcription.

The nitrogenous sequences in this RNA molecule are then translated into the proteins through the process of translation during which the sequence is read in pairs of three called "codons". A specific amino acid is attached to the peptide when the codons are read by the translation machinery and a protein is formed.

These proteins could perform various roles in organisms from physical to biochemical and thus the physical traits are controlled by the DNA.

When a plant grows toward or away from a stimulus, it’s called a tropism.
harina [27]

Explanation:

Phototropism- a response to <u>light stimulus</u> that directs the stem to grow toward the light and roots to grow away from it.

ii. Gravitropism- Stems and leaves grow away from the force of <u>gravity</u> while roots grow toward it.

iii.Thigmotropism - growth in response to <u>touch stimulus.</u> The side of the stem in contact with the object grows slower than the side not in contact. This causes the vine to twist around the object.

How the seismic tracings recorded at station A and station B indicate that station A is farther from the earthquake epicenter th
VMariaS [17]

The seismic traces recorded at station A and station B indicate that station A is further from the earthquake epicenter than station B because the ground movement detected at B was greater than that detected at A, with seismic waves more frequent and less frequent respectively.

<h3>Seismograph</h3>

A seismograph is a device that detects ground movements, including those generated by seismic waves. It consists of the basic sensor of the seismographic instruments of which the seismograph and the seismoscope are part. These movements are then recorded in seismographs, which have been plotted graphs called seismographs.

<h3> Propagation speed</h3>

Seismic station A is located 5,400 kilometers from the earthquake's epicenter. How long would it take for the first S wave produced by this earthquake to reach seismic station A? The propagation speed of this type of waves varies with the medium in which they propagate, with typical values ​​of

  • 330 m/s in air
  • 1 450 m/s in water
  • and 5 000 m/s in granite.

They are not as destructive as S waves or the surface waves that follow them. The propagation speed of these waves is, in general, slightly less than twice that of S waves.

With this information, we can conclude the velocity of propagation of seismic waves and how a seismograph enumerates the distance from the epicenter of an earthquake.
