Collagen is a protein fiber that is found in the matrix that lies outside the bone cells. Population of these collagen fibers that scattered through the matrix are embedded in a gel-like ground substance called hyaline cartilage, which is flexible but avascular and contains no nerves or blood vessels.
"Conjugation" is the one process among the following choices given in the question when <span>two protists exchange genetic material. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has come to your great help.</span>
Answer:
The correct answer is Most DNA binding protein would have strong positive charge .
Explanation:
DNA is the genetic material in most organism. DNA consist of nucleotides that contain a nitrogen base,deoxyribose sugar and phosphate group. The phosphate group is highly reactive and contain negative charge.
Most DNA binding protein such as Helix turn helix, Leucine zipper,Zinc finger Interracts with the negatively charged phosphate group by the positive charge that they contain . This positive charge facilitates their interraction with negatively charged DNA molecule.
Answer: The correct answer for the blank is-
Energy is released from ATP ( adenosine triphosphate) when high energy phosphoanhydride bond ( present between two phosphate) is broken down or hydrolyzed.
This results in the formation of ADP ( adenosine diphosphate) and Pi ( inorganic phosphate).
Therefore, hydrolysis of ATP releases energy.
Answer: the membrane channel
Explanation:
In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Thus the water will move from an area of high concentration to an area of low concentration, until the system reaches a steady state called equilibrium- after this, there will be no net movement of water. Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.
The dialysis tubing mimics a semi permeable membrane; it only allows water and small molecules of iodine to cross into the bag containing starch. The tubing is impermeable to starch; these large molecules require the aid of protein omplexes called membrane channels, in order to move across the membrane and against the concentration gradient.
