Answer:
Polar; hydrophobic (Ans. B)
Explanation:
Glycerophospholipids are known as the class of lipids which are found extensively in the biological membrane. They are usually consisting two regions of lipids which provide structure to the lipid bilayer in which the hydrophilic heads (polar) attaching outside to the cell and the hydrophobic tails (non-polar) pointing insides to the cell membrane.
Glycerophospholipids helps to provide permeability and fluidity to the membrane and also helps in the programmed cell death, and modulation of actions of membrane-bound enzymes.

Answer:
(2) 988.5 mb.
Explanation:
The air pressure descends as we ascend. In other words, they are inversely proportional.
The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.
Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
Natural selection. The trait that is unfavorable to the baby giraffe's survival will cause the death of giraffes with that specific gene that is responsible for a short neck vs a long neck. Natural selection causes traits that help the survival of the species will be carried throughout generations while unfavorable traits will be lost.
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
