<u>W</u><u>hy does facilitated diffusion happen</u><u>:</u>
<em>~</em><em> </em><em>I</em><em>t regulates what goes in and what goes out of the cell</em>
<em> </em><em>~</em><em>T</em><em>he cell membrane is permeable to only a select few types of molecules</em><em> </em><em>and</em><em> </em><em>t</em><em>h</em><em>e molecules that are allowed to move across the cell membrane must be non-polar molecules which are small in size</em>
<u>W</u><u>hat direction the particles diffuse in</u><u>:</u>
<em>~</em><em>F</em><em>rom one side of the membrane where the substrate concentration is high to the other side of the membrane where the concentration is lower</em>
<em>~</em><em>D</em><em>iffuses across membranes down the concentration gradient</em>
<u>T</u><u>he molecules that help in this process</u><u>:</u>
<em>~</em><em>carbohydrates, amino acids, nucleosides, and ions</em>
Hope this helped you- have a good day bro cya)
Amoeba
is not considered as a body part <span>but it has similar
characteristic to unicellular and multicellular,
this is the reason why it is an outgroup in the cladogram. </span>In addition, to be
considered as an <span>outgroup,</span> an
organism must be part of a group on the tree but just very similar with the members
on that tree.
DNA polymerase is the answer. Hope it helps. Cheers mate
Type II restriction enzymes, such as Ecor I, that make staggered cuts within its recognition sequence, are considered more effective in biotechnology because they result in cohesive or sticky ends.
<h3>What is Ecor I and why are sticky ends important?</h3>
Ecor I is a kind of restriction enzyme which is obtained from Escherichia coli. The palindromic sequence recognized by this enzyme is 5' - GAATTC - 3'. It makes the following cuts between G and A on both the strands of the DNA to form sticky ends:
5' - G↓AATTC - 3'
3' - CTTAA↑G - 5'
Sticky ends are a fragment of DNA which is produced through a staggered cut, by the use of restriction enzyme. In this the terminal portion stretches with unpaired nucleotides. These kind of ends are easy to ligate when rDNA needs to be formed.
