There’s are 3 elements: Carbon, Hydrogen and Oxygen

Ethanol consists of 9 atoms:

2 Carbons
6 Hydrogens
1 Oxygen

2 + 6 + 1 = 9 atoms in total

Although the question doesn’t ask for atoms I just wanted to make things clear between them so you don’t get the numbers mixed up. Apart from that, there are 3 elements present in Ethanol.

Restriction enzyme HinfI cleaves a five nucleotide DNA sequence GA(A/T)TC. The ambiguity in the central position - (A/T) - means
Afina-wow [57]

Answer:

C) 2.0 kb

Explanation:

It is given that out of the 4 nucleotides A, T, C & G each one has equal probability to occur at any position on the DNA molecule which simply means that the probability of occurrence of any nucleotide at a position is 1/4.

Also, it is given that probability of occurrence of either A or T at 3rd position is equal which means that the probability at that particular position will be 2/4 = 1/2.

Now, GA(A/T)TC is the DNA sequence where Restriction enzyme HinfI cleaves so the total probability of an average HinfI cleavage fragment will be = 1/4 x 1/4 x 1/2 x 1/4 x 1/4 = 0.00195 = 0.2 i.e. 2 kb.

A nerve poison that blocked neurotransmitter receptors on the dendrites would __________. inactivate the enzyme that degrades th
Svet_ta [14]

The correct answer is: prevent reception of a signal in a receiving neuron

Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.

Drugs that bind to neurotransmitter’s receptor can have two effects on its action:

• Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it

• Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).
