Draw the Lewis structure (including all lone pair electrons) for one isomer of the molecular formula C3H8O.
Andreyy89

Answer:

Here's how I would do it.

Explanation:

A Lewis structure shows the valence electrons surrounding the atoms.

1. Identify the central atoms

The central atoms are the least electronegative atoms (C).

I chose as my central atoms a chain of four C atoms: C-C-C-C

I stuck the most electronegative atom (O) at the end of the chain:

C-C-C-C-O

2. Complete the structure

The hydrogen atoms must be terminal. Add enough to give every atom an octet.

You should get a structure like the one below

In his transformation experiments, what did Griffith observe? Group of answer choices
masya89 [10]

Answer:

The correct answer is a. mixing a heat killed pathogenic strain of bacteria with a living non pathogenic strain can convert some of the living cells into the pathogenic form.

Explanation:

Griffith proved that DNA is the genetic material in some organism.To do this he described the process of transformation in which the heat killed pathogenic bacteria when mixed with a non pathogenic bacteria can convert the non pathogenic strain into pathogenic one. This principle is called transformation.

       The transformation of non pathogenic strain into pathogenic one occur due to the uptake of DNA of the heat killed pathogenic bacteria by the non pathogenic strain.
