Refined grain products like bread, flour tortillas, white rice, cornmeal, crackers etc are enriched with riboflavin, niacin, iron and thiamin.
Enriched grains is finely ground endosperm of the kernel. Enriched grain products are good as a source of iron and four types of vitamin B which includes niacin, thiamin, folic acid and riboflavin and also contains some complex carbohydrates.
Wheat and rice are a staple diet in many regions of the world but excessive polishing and refining the cereals removes the essential nutrients or vitamins which have their own important physiological roles.
Generally speaking, enzymes (which amylase happens to be) do not undergo any permanent structural change while carrying out their function. Some do exhibit transient conformational change during a reaction, but upon completion regain their original form.
So your initial assumption is correct: once amylase has finished catalyzing the breakdown of starch into less complex sugar molecules, it moves on and repeats the process over and over.
There are six aorganells in an animal cell. The Nucleus, Ribosomes, Endoplasmic reticulum, Golgi apparatus, Chloroplasts and the Mitochondria.
Answer:
The correct answer is option e) "Over time, we could see an increase in the H1 allele frequency".
Explanation:
The bighorn sheep (Ovis canadensis) is a species that is a very attractive for hunters because of its long horns. This negative human influence has make that bighorn sheep with long horns struggle to survive and reproduce. Horn size in bighorn sheep is determined primarly by a gene called HRN, which has two alleles H1 (for long horns) and H2 (for smaller horns). if hunting were discontinued for bighorn sheep in a large population we can predict that over time, we could see an increase in the H1 allele frequency, because in this population bighorn sheep with long horns will have better chances of surviving.
