Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane. Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. ... Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size.t is the proteins, therefore, that give each type of membrane in the cell its ... Many extend through the lipid bilayer, with part of their mass on either side ..... Many hydrophobic membrane proteins can be solubilized and then purified in an active, if not entirely ..... Many Membrane Proteins Diffuse in the Plane of the Membrane.
hope this helps :)
Warning Dont copy all of this i just answered this question to give you idea of what it is
Answer:
<h2>Chalamydomonas.</h2>
Explanation:
Protists are those organisms that are unicellular and eukaryotic in nature. They are present in diverse forms and structures and show different types of characteristics/. There are many protists that are harmful to human beings and some other organism that causes certain diseases called parasitic protists such as protozoans, trichomonas and some other. There are some protists that are not parasitic in nature such as Chlamydomonas and some other. Protists have different types of the mode of nutrition that may be autotrophic, saprophytic and parasitic and some other.
Most of the nerve fibers of the sympathetic division of the autonomic motor pathways arise from the inter-mediolateral horns of the gray matter of spinal cord.
<h3>
What is sympathetic nervous system ?</h3>
The autonomic system is up two types such as the sympathetic and parasympathetic systems.
Both subsystem work antagonistically but in an integrated manner.
Sympathetic system is highly essential for preparing our body during emergencies for 3 F responses such as fight, fright and flight.
During this response, sympathetic system activates complex pathways for faster breathing, increased heart rate and blood pressure.
Hence, the inter-mediolateral horns of the gray matter of spinal cord is correct answer.

Answer:
D.Convention
Explanation:
The four main mechanisms that lift the air in the atmosphere and create clouds are a) Convection; b) Convergence; c) Updraft and d) Orographic Lifting
Radiation, conduction and water vapor are not responsible for creating lift in the atmosphere.
In convection, heat energy from sun raises the temperature of surface of the earth as it passes through the atmosphere. The air near the surface become less dense and hence starts rising thereby creating a lift.
