Beriberi is a vitamin deficiency disease caused by a deficiency in___ , as this is a precursor to the coenzyme ___, which is used in the ___ reactions of the citrate cycle. Brown rice, in which the bran of the rice remains, is considered more nutritious than white rice, in part because this vitamin is not removed. Beriberi can also be caused by consuming foods that contain high levels of ___ , such as uncooked fish and silkworms.

*thiamine

*thiamine

*pyruvate

"thiaminase

Explanation:

Beriberi is a vitamin deficiency disease caused by a deficiency in *THIAMINE* as this isa *THIAMINE*

precursor to the coenzyme which is used in the *PYRUVATE*reactions of the citrate cycle. Brown rice, in which the bran of the rice remains, is considered more nutritious than white rice, in part because this vitamin is not removed. Beriberi can also be caused by consuming foods that contain high levels of *THIAMINASE*, such as uncooked fish and silkworms.

Beriberi is a disease which is also called thiamine deficiency is caused as a result of deficiency in by a vitamin B-1. Beriberi disease can occur in two ways, as wet beriberi or dry beriberi.

Dry beriberi usually attack the nerves and later damage it and which lead to weakening of muscle and eventually paralysis of muscle.

On the other hand, Wet beriberi attack the heart as well as the circulatory system, which can result to heart failure in extreme condition.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
