In order to be carried in the chylomicron, retinol (once in the enterocyte) is esterified by lecithin retinol acyl transferase.
All-trans-retinol is referred to as vitamin A, when a fatty acyl group is esterified to the hydroxyl terminus of retinol, a storage form of retinol, the retinyl ester, is formed. In tissues, retinal serves as an intermediate in the synthesis of retinoic acid from retinol.
Answer:it would the truth only in case it have scientific proof
Answer:
. d. peas have an unusually long generation time
Explanation:
Gregor mendel is a scientist, he was bored 20th July,1822. He carried out an experiment using pea plant and he is reffer to as the father of genetist. Mendel used seven traits of the pea plant in his experiments this include flower color which is either purple or white, flower position which is either axil or terminal stem length which could be long or short, seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted) and pod color (yellow or green). He uses pea plant because of the following reason,
pea plant has many observable characteristics that could be used such as flower colors,seed shape.
Pea plant is an annual crop that matures early, so earliness to maturation makes Mendel select pea
Mating in pea plant can be controlled. Pea plant are self fertilizing crop but he decided to control the mating pattern by cross fertilize them and avoiding contamination from other pea plant.
The experiment with pea pant would produce enough seeds for subsequent generation.
This experiment made Mendel propound 2 laws, law of segregation of gene and law of Independent assortment of gene.
As discussed in Unit 10 of The Physics Classroom Tutorial, electromagnetic waves are waves that are capable of traveling through a vacuum. Unlike mechanical waves that require a medium in order to transport their energy, electromagnetic waves are capable of transporting energy through the vacuum of outer space. Electromagnetic waves are produced by a vibrating electric charge and as such, they consist of both an electric and a magnetic component. The precise nature of such electromagnetic waves is not discussed in The Physics Classroom Tutorial. Nonetheless, there are a variety of statements that can be made about such waves.
<span>All four nucleotides (adenine, guanine, thymine, cytosine) are synthesized in the liver. The nucleotides can be synthesized de novo or recycled through salvage pathways. The synthesis occurs in the cytoplasm of the cell, not within a specific organelle. The components which are used for the nucleotide synthesis are derived from biosynthetic precursors of carbohydrate and amino acid metabolism, and from ammonia and CO2.</span>
