Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
Answer:
C. Water
Explanation:
The cells in our bodies are full of water. The excellent ability of water to dissolve so many substances allows our cells to use valuable nutrients, minerals, and chemicals in biological processes. Water's "stickiness" (from surface tension) plays a part in our body's ability to transport these materials all through ourselves.
Neutrons protons and electrons
I believe that the most contaminated are is the kitchen sink. Researchers say that the sink can contain up to 100,000 times more bacteria than the toilet seat. This is because the sink is where everything is slopped in.The sink should be washed with hot water and disinfected regularly to kill the harmful bacteria.
Answer:
Hydrogen Bonds
Explanation:
The arrangement of phospholipid bilayer of plasma membrane is such that ; the polar phospholipid heads point outwards into the watery external environments. This Polar environment is Hydrophilic or water loving, while the water- hating hydrophobic tail region pointed inwards away from the watery medium.
This gives the usual bilayer shape to the plasma membrane,with the tail facing one another and heads outward.
The hydrogen bond is formed as inter molecular forces between the hydrogen atom (positive side)of water molecule and oxygen atom (negative side)of the polar molecules e.g glucose, to form an idea dipole -dipole force interactions,
Polar Compounds, glucose, urea dissolved easily in hyrophilic watery environment to from Hydrogen bonds with water
<u>The correct answer is Hydrogen bond a dipole dipole force</u>
