7. Phytochrome prevents seeds of some plants from germinating when they are in deep shade by the: absorption of far-red waveleng
SIZIF [17.4K]
<h2>Function of Phytochrome </h2>

Explanation:

  • The <em>color of light</em> that they absorb maximally by the two types such as   <em>Pfr is a blue-green structure</em> that ingests far-<em>red light (730 nm)</em> and<em> Pr is a blue structure that retains red light (660 nm)</em>
  • <em>Pfr assimilates far-red light</em>, it is changed over to the <em>Pr structure</em>
  • Pfr can spontaneously revert to the Pr form  structure in obscurity <em>dark over time = dark reversion Pfr</em> is additionally helpless to proteinases
  • <em>Pfr contains  some red light, so in red light 15% Pr and   there is a parity of 85% Pfr.</em>
  • <em>The  phytochrome (Pr)</em> is changed over to the organically dynamic structure red light with the <em>Pfr under illumination</em>
  • <em>Darkness and Far -red light convert</em> the particle back to the inactive form.

explain : in order to get rid of any effects of agricultural insecticides in the fruits, it is advised to soak them in a diluted
Vedmedyk [2.9K]

As we have studied in junior classes <em>that all animals including bacteria contain a plasma membrane around their cell which controls the movement of water and materials to and from the cell.</em>

The bacteria are the main hazard in pesticides and if we study about its structure, it contains both cell membrane and cell wall. Now another point in that bacteria lives in a moist or hypotonic environment in which the concentration of water inside the cell is less than the concentration of water outside the cell. This results in more movement of water from outside to inside the cell since we know that water moves from a place of higher concentration to a place of lower concentration.

Now when the water moves inside the bacterial cell, it can burst bacterial cell but thanks to the presence of cell wall which donot lets the burst caused.

So coming towards sugar solution, when bacteria are dipped in dilute sugary , the outside environment around a cell is sugary, and the concentration of water in the solution is less than inside the cell and water tends to leave the cell. the major effect of sugary solution is that it withdraws water from inside the body of micro organisms if the external concentration of sugar is high enough. When the water will move out of their body, they will die and their spores will not be able to germinate too.

This will eventually make our food (vegetable, fruit or any other) clean.

Hope it helps!

6) The Honeydough Bread factory produces 2,000 loaves of bread per day. During bread making, ____________ by yeast produces ____
diamong [38]
During bread making, metabolism of simple sugars by yeast produces carbon dioxide which makes the bread rise. The essential ingredients of bread dough are flour, water and yeast. As soon as these ingredients are stirred together, enzymes in the yeast and the flour cause large starch molecules to break down into simple sugars. The yeast metabolizes these simple sugars and exudes a liquid that releases carbon dioxide and ethyl alcohol into existing air bubbles in the dough. If the dough has a strong and elastic gluten network, the carbon dioxide is held within the bubble and begins to inflate it, just like someone blowing up bubble gum. As more and more tiny air cells fill with carbon dioxide, the dough rises, and so we see bread rising.

Enzymes that add ubiquitin to proteins have been found in the nucleus of eukaryotic cells. These enzymes would be most likely to
Kobotan [32]

Answer:

causing degradation of transcription factors and changing which genes are expressed

Explanation:

Ubiquitination  (addition of ubiquitin to a protein) is the first step in protein degradation process, and it directs  protein to the proteasome for degradation. This process involves three steps with specific groups of enzymes to perform them, which are activation with ubiquitin-activating enzymes, conjugation with ubiquitin-conjugating enzymes and ligation with ubiquitin ligases. These enzymes would be most likely to regulate gene expression by causing degradation of transcription factors and changing which genes are expressed.
