The fatty acids in the tail of a phospholipid molecule are non-polar and hydrophobic.
Fats that you take in from your food is used to build membranes. Membranes can be represented by models such as The Fluid Mosaic Model, which displays the phospholipid bilayr, and other tissues on the membrane.
According to the equation the correct answer with the interval registered in minutes is: C
8=0.00146 (distance to epicentre) <=> distance to epicentre=8÷0.00146 <=>5479,45 km
In eukaryotes, the DNA strands are linear, and DNA polymerase can't replicate the very ends of the DNA strands! These ends are "protected" by repeated sequences called "telomeres." Either the chromosome gets shorter with each replication, or else a special enzyme-nucleic acid complex called telomerase adds new telomeres to the ends. A prokaryotic chromosome is circular and thus does not have the problem of having ended.
<span>Eukaryotic DNA is wound around histones, coiled, and supercoiled -- to replicate it, there have to be unwinding mechanisms, and mechanisms to reduce the degree of coiling. In prokaryotes, the winding problem is much less, and there aren't any histones.</span>
Answer:
Explanation:
As the water waves go through the gap they spread out, this is called diffraction.
The longer the wavelength of the wave the larger the amount of diffraction.
The greatest diffraction happens when the gap size is about the same size as the wavelength.
Answer:
Myelination
Explanation:
The covering of myelin around the axons is called the myelin sheath. This myelin sheath helps in transfer of information faster and also in complex processes of the brain. The process of myelination begins in the PNS (peripheral nervous system).
The myelinated section are seperated from each other with a gap called nodes of ranvier. Glial cells (oligodendrocytes) forms the myelin sheath in the central nervous system and schwann cells (glial cells) forms the myelin sheath in peripheral nervous system. The propagation of electrical impulse in the myelinated fibers is by saltatory conduction that is from one node to another.
