Answer: the best statement is 1 (Vitamin B12 (cobolamin) is missing from the vegan diet and very low in the lactovegetarian diet.)
Explanation:
Vitamin B12( cobalamin) is a water soluble vitamin that is essential in the formation of red blood cells. It also serves as a coenzyme in the metabolic reaction of the body. Such reaction includes:
- the remethylation of methionine from homocysteine which is catalyzed by methionine synthase and requires methylcobalamin.
The deficiency of vitamin B12 can lead to the following:
- elevated homocysteine ,
- an increase in methylmalonate
This is due to deficiencies in methionine synthase and methylmalonic acid mutase, respectively in individuals on vegan diet for several years.
Vegans are vegetarians that don't include diary or animal products in their meals. This predisposes them to lack of Vitamin B12. Dairy products provide some vitamin B12 in the lactovegetarian diet. Therefore statement 1 is the correct answer, thanks.
I think it’s “Removed from”
Answer:
a rection will most likely occur if the colliding partilces have the proper orientation and energy. The reactions occur becasue the molecules collide. But not all the collisions result in a reaction. The collisions have to meet some requirements
Explanation:
Isotopes and most average aren't whole numbers
Answer:
A chemical change occurred, so even if Cash heats it, the white solid will remain.
Explanation:
- A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A physical change occurred, so even if Cash heats it, the white solid will remain.
- A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A chemical change occurred, so even if Cash heats it, the white solid will remain.
<em>The correct answer would be that a chemical change occurred, so even if Cash heats it, the white solid will remain.</em>
Chemical changes occur when atoms in a substance or mixture of substances are rearranged, leading to the formation of new substances.
<u>In this case, the mixture of the two clear liquids led to the formation of gas in form of bubbles and a white solid forms that settle at the bottom. The formation of these 2 substances from the mixture of the two clear liquid is an indication of chemical reaction/changes. Hence, even if cash heats the resulting mixture, the white solids will likely remain.</u>
