Bacteria are prokaryotes and microscopic in size, and they lack a nucleus. DNA is present in the cytoplasm. They do not have membrane-bound organelles.

<h3>What is the size of bacteria?</h3>
  • The shapes and sizes of bacteria are extremely diverse.
  • The majority of bacteria have a 2–8цm length and a diameter of 0.2-2цm.
  • Eukaryotic cells are around ten times larger than bacterial cells.

<h3>What is the difference between prokaryotic and eukaryotic cells?</h3>
  • Prokaryotic cells are primitive cells that are primarily present in unicellular organisms; they lack a nucleus but contain a small amount of DNA and do not have membrane-bound organelles.
  • In contrast, eukaryotic cells are present in all types of multicellular organisms, including plant and animal cells.
  • It possesses a nucleus. All cell organelles are membrane-bound.
  • Because they lack a nucleus and other cell organelles and are single-celled microorganisms, they are categorized as prokaryotic organisms.

Bacteria are tiny organisms. They are 200 micrometers in diameter. They do not possess membrane-bound organelles.

A certain area received a large amount of rain and some of it remained on top of the soil. What happened to the rest of this wat
ValentinkaMS [17]

In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.

<u>Explanation:</u>

  • Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.  
  • When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
  • The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.  
  • The water is an essential requirement for survival and the existence of biological organisms.

Explain the difference between each of the following substitution mutations:
pentagon [3]

Answer: silent mutation: a nucleotide base in a codon is replaced with a different base BUT the resulting amino acid isn’t affected.

Missense mutation: similar to a silent mutation, the only difference is that the switch of the nucleotide DOES result in a DIFFERENT amino acid

Nonsense mutation: a nucleotide base is changed, but that change results in a premature stop of translation

(Remember that after transcription, you are left with a strand of mRNA that Is then translated into a protein. The mRNA is read in increments of three nucleotide bases (A,U,G, or C) which is called a codon. That codon makes a single amino acid, and a strand of amino acids makes a protein)

An investigator attempting to replicate Pasteur's swan-necked flask experiment has boiled a hay infusion for 1 hour. However, sh
blsea [12.9K]

Answer:

Hay infusion refers to an amalgamation that can be formed by taking samples from different sources like rivers, lakes, ponds, and others. It is one of the best procedures that can elevate the density of the bacteria cell at any specific time interval.  

In the given case, even after boiling hay infusion for one hour, growth was observed in the flask after one day. It can be due to certain factors like the hay infusion may have been comprising some endospore, which is resistant to heat or may comprise some kinds of bacteria that can withstand high temperatures.  

Because of which, even after heating the infusion for one hour, it did not get influenced by the heat and got the chance to grow when it got optimum temperature again at the time when the sample was left as such.
