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.
Its Fins, gills, and tail are all crucial for a sharks survival
This would be a recessive disease.
Father is dd
Mother is Dd (has to be because one child has the disease)
Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!
It helps you organize your data, and so its not a complete mess when you need to refer back to it. It will help you organize and not confuse and miscompare information. It also looks better and looks like you know what you're doing.
Answer: Principle of Original Horizontality.
According to the principle of original horizontality all rock layers are horizontal in nature and this is specific to sedimentary rocks. The younger sediments remains in the top layers and older ones remains at the bottom. These sediments accumulate in horizontal and parallel layers and becomes compact to form rocks in the end.
