O, the most popular types of blood the predominant
Answer:
the cell wall which is the cell membrane
Explanation:
the cell membrane gives the cell its shape and it protects the bacterial cell from the environment.
<h3>Phototropism</h3>
Yes, the given activity is a correct example which describes phototropism
Phototropism is an adaptation or a survival mechanism undertaken by some plants to receive maximum sunlight in order to prepare more food and energy through photosynthesis.
Explanation:
Phototropism takes place through receptor proteins called phototropins which act as blue light photoreceptors.
Phototropic activity:
Phototropism can best be observed by planting few plants including phototropic plants in pots and keeping them near the window to receive sunlight.
The natural bending of phototropic plants towards the window denotes their inclination towards sunlight.
The growth of sunflower plants facing towards the sun and blooming of lotus flower under sunlight are all examples of phototropism.
Other plants which are phototropic are Phalaenopsis, azuki beans, fungus of Phycomyces species, etc.
The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ = 
(for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ = 
(for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

When a hairpin loop forms in the nascent mRNA: The hairpin will destabilize the interaction and possibly lead to transcriptional termination.
Transcription in prokaryotes like E. coli is terminated either by a rho-dependent process or a rho-independent process. Intrinsic termination is controlled by the specific sequences of RNA .
When the termination process starts, the transcribed mRNA forms a stable secondary structural hairpin loop, also known as a stem-loop. Several uracil nucleotides follow this RNA hairpin. The uracil and adenine connections are exceedingly weak. NusA, a protein attached to RNA polymerase, attaches to the stem-loop structure so firmly that it momentarily stalls the polymerase.
The polymerase is pausing at the same time that the poly-uracil sequence is being transcribed. The RNA-DNA duplex can unwind and separate from the RNA polymerase because the weak adenine-uracil interactions reduce the energy of destabilization for the RNA-DNA duplex. Overall, transcription is terminated by the modified RNA structure.
