These cells line focal pits of the CNS and, in specific spots, deliver CSF. The cilia of these cells help flow the CSF that sustains and pads the mind and spinal string. Expansions from these cells wrap vessels and give additional control over which materials enter or leave the intercellular liquid of the CNS.
Answer:
The most appropriate answer would be option 2.
In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.
A set of 15 genes is responsible for the color of the eyes. Two genes out of these 15 are OCA2 and HERC2 which are present on chromosome 15.
Thus we can conclude that eye colour is polygenic trait which does not follow Mendelian genetics.
Germ or embryo is the smallest portion of the grain, and the embryo for a future plant found at the base of the whole grain or kernel that accounts for 2.5 percent of the grains weight. It is very rich in fat, vitamins, minerals, incomplete protein and an excellent source of B vitamins and vitamin E which is collected and sold separately and makes the whole grains susceptible to spoilage.
The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell's nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
Accretion is a process by which material is added to a tectonic plate or a landmass. This material may be sediment, volcanic arcs, seamounts or other igneous features. There are two types of geologic accretion—plate accretion and landmass accretion. The Plate accretion involves the addition of material to a tectonic plate. The Landmass accretion involves the addition of sediment to a coastline or riverbank, increasing land area.
