The answers include the following:
- Graphite conducts electricity because it has delocalised electrons which makes it possible for the electrons to move freely.
- Graphite is slippery because it has layers which makes it possible for the atoms to slide over each other.
<h3>What is Graphite?</h3>
This is referred to as an allotrope of carbon and it is the most stable form. it is used in the production of substances such as pencil, electrode etc.
Graphite is able to conduct electricity because of the presence of delocalized electrons and is slippery due to its atoms being able to slide over one another.

Answer:
H2 is the limiting reactant.
Explanation:
From the diagram above:
H2 => White ball
O2 => Red ball
Before the reaction
H2 => White ball => 10
O2 => Red ball => 7
After the reaction
H2O => White and red ball => 10
O2 => 2
From the simple illustration above, we can see that all the H2 were used up in the reaction but there are left over of O2.
This simply means that H2 is the limiting reactant as all of it is used up in the reaction while O2 is the excess reactant as there are leftover.
I think the answer is B or the 2nd one, hope this helped c:
Sequence specific dna binding proteins recognize the nucleotide sequence of double-stranded dna primarily by forming non-covalent bonds with <u>Chemical groups on the edges of paired bases within the major groove.</u>

What Are DNA-Binding Proteins?
DNA is the blueprint for the cell. It contains information that codes for all of our traits. Essentially, our DNA is what makes us, us. But, DNA doesn't do this in isolation. There are thousands of proteins in our cells that help modulate DNA's functions. These proteins are called DNA-binding proteins, because they attach to DNA.
DNA binding proteins do many jobs including controlling protein production, regulating cell growth and division, and storing DNA inside the nucleus. Thus, if DNA is the blueprint to build the human body, then DNA-binding proteins are the parts of the cell that read and interpret the instructions to actually create and maintain the body. Let's look at the different types of DNA-binding proteins and examples of each.
