Answer:
Correct option: a (tetrahedral)
Explanation:
According to VSEPR theory tetrahedral arrangement comes when central atom have four electrons pair in the valence shell and only in this arrangement electron pair will fell less repulsion that is why it is arranged in this way and VSEPR theory electrons pair are arranged in such a manner that they fell less repulsion.
they might have different number of bond pair and lone pair that depens on the number of bonded to other atom.
Hence opion a is correct.
Answer:
Since previous studies had shown that the brain's visual center lights up with activity when someone does a purely smell-related task, a group of researchers set out to test what these two senses have to do with each other. ... The electric current startles that area of the brain into extra activity.

<h3>What is Lewis Structure?</h3>
A Lewis Structure is a very simplified presentation of the valence shell electrons in a molecule. It is used to show how the electrons are organized around particular atoms in a molecule. Electrons are displayed as "dots" or for bonding electrons as a line between the two atoms.
- Lewis structure does NOT endeavor to explain the geometry of molecules, how the bonds compose, or how the electrons are transmitted between the atoms.
- It is the easiest and most limited theory on electronic format.Lewis systems show separately atom and its position in the structure of the molecule using its chemical symbol. Lines are drawn between atoms that are connected (pairs of dots can be used instead of sequences). Excess electrons that form lone pairs are defined as pairs of dots and are positioned next to the atoms.

Imatinib is a small molecule kinase inhibitor. The BCR-ABL kinase can phosphorylate a series of downstream substrates, leading to proliferation of mature granulocytes. Bcr-Abl kinase substrate is the tyrosine. The Protein Tyrosine Kinase activity is an important requirement for malignant transformation, and that it cannot be complemented by any downstream effector, though not all interactions of BCR-ABL with other proteins are phosphotyrosine dependent.
