To complete the sentence: Rhythmic contractions of the male and female reproductive structures occur during the orgasmic phase. It is the rhythmic contraction of the <span>bulbospongiosus and ischiocavernosis muscles. This is happening during an intercourse. I hope this answer helped.</span>
Answer:
B i hope this help
Explanation:
The cell membrane consists primarily of a thin layer of phospholipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer approximately 7 nm thick, barely discernible with a transmission electron microscope.
The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevent polar solutes (e.g. amino acids, nucleic acids, carbohydrates, proteins, and ions) from diffusing across the membrane, but generally allows for the passive diffusion of hydrophobic molecules. This affords the cell the ability to control the movement of these substances via transmembrane protein complexes such as pores and gates.
Answer: Your answer would be B monosaccharides.
Explanation: the monomer for lipids is triglycerides so it cant be A. The monomer for proteins is amino acids so D is out. Enzymes are not monomers they are proteins which are made up of the monomer amino acids.
Hope this helps you :))
Cardiac muscle cells appear striates or striped under a microscope.
It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.
