Answer:
Yes they can
Explanation:
<em>Based on the fluid mosaic model of the lipidic bilayer of the membranes we know that proteins embedded in it have the ability to undergo translational diffusion</em>. <em>Membrane fluidity is important to the cell because is associated to transport rates, it can respond to the necessities of the organism,</em> for example, in some organisms this fluidity can be modified by temperature stress or according to their nutrient necessities.

Answer:
The correct answer is a inducer(lactose) = acts by stepping on the gas pedal.
Explanation:
In lac operon lactose act as an inducer.Lactose exerts its action by binding with the repressor and inducing a conformation al change in the repressor molecule and prevent the later from binding to the operator region.
This ultimately result in the expression of the structural genes such as Lac Z ,Lac Y and Lac A.
According to the given question if the lac operon is described using a car analogy then the inducer lactose will act by stepping on the the gas pedal and this is the positive regulation of Lac operon.
I do believe the second answer is the right one
The calcium that triggers muscle contraction is stored in synaptic vesicles called endoplastic reticulum. that is not the only function of the endoplastic reticulum it is also a network of a membranous tubules within the cytoplasm of a eucryotic cell continuous with the nuclear membrane.
