Answer: the correct answer is energy-release from energy-yielding nutrients.
Explanation:
Thiamin is found in meals like cereals, wholemeal grains, meat, nuts, beans, peas. Thiamin is important in carbohydrates degradation in necessary products for the body. Thiamin is used for treatment or preventing deficiency in vitamin B1.
Answer: The DNA on the paternal copy of the chromosome will be methylated at the imprinting center, while the DNA on the maternal copy of the chromosome will not be methylated in this region.
Explanation:
Chromosomes are DNA structures associated with proteins such as histones. They are found in the nucleus of cells and contain genetic information for the development and functioning of an organism. Human beings are diploid, meaning that they possess two copies of each of the 23 chromosomes (a total of 46).
Gametes, which are sex cells such as the sperm (produced by the male) and the egg (produced by the female) that are haploid. This means that they possess only one chromosome of each pair. During fertilization, a male gamete fuses with a female gamete to generate a zygote, which will give rise to a new human being. <u>This new individual will possess half of the genetic material from its father and half from its mother. Thus having a total of 46 chromosomes, 23 from each parent</u>.
Genetic imprinting modulates gene expression by chemical modification of DNA and/or modification of chromatin structure. Often, genetic imprinting causes a gene to be expressed only on the chromosome inherited from one of the parents. One example of imprinting is DNA methylation, which is a process by which methyl groups are added to DNA. <u>Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed</u>, that is, it will not produce a protein encoded by that gene. So, if a region of DNA is imprinted in the sperm cell, the paternal chromosome inherited from this sperm will be methylated in the genes of the offspring. And the offspring will only express the maternal copy inherited, which will not be methylated.
As the ocean level rises sea water floods inland and puts a risk to water reserves like dammed lakes and other places by contamination
There are two approaches used when inserting a pacemaker; the epicardial approach and the transvenous approach. Epicardial approach involves the opening the chest cavity and placing a lead on epicardial sac of heart while the transvenous approach involves accessing a vein and inserting an electrode into the vein. Epicardial approach for inserting pacemakers are divided based on approach to heart thoracotomy, upper abdominal or endoscopic.
