A monkey attends to a moving stimulus left of fixation then to a stationary stimulus right of fixation. if one were recording mt neuronal activity, it would reveal that _____.? a. ?the neuron preferentially responding to the left stimulus is inactive when attending to the right stimulus b. ?the receptive field associated with the neuron responding to the left stimulus shrinks when attention shifts to the right stimulus c. ?the neuron preferentially responding to the left stimulus is unaffected by attention to the right stimulus d. ?the receptive field associated with the neuron responding to the left stimulus shifts right when attention shifts to the right stimulus


correct answer to this is the event of:


Great Depression”


The Great
Depression occured from 1929 to 1939, and was the most horrible economic recession
in the history. It started after the stock market crashed on October 1929,
which sent Wall Street into panic and erased millions of investors. This considerably
hanged the popular view of government’s appropriate role in the economy. The
Great Depression convinced a lot of people that the government had a role in
correcting for aggregate market failures and hence leading to a shift from Laissez-Faire
view towards a more activist view of the government.

Helicases unwind the two parental DNA’s strands and creates the replication fork; single strand binding proteins keep the single strand from joining.

Further information:

• DNA replication: a biological method occurring in all living organisms that is the basis for biological inheritance

Helicase: It is an enzyme that may unwinds the DNA helix ahead of the replication machinery.

Origin of replication: a specific sequence in a genome at which replication is started.

Steps of DNA replication:

• During initiation, proteins fix to the source of replication while helicase unwinds the DNA helix and two replication forks are formed at the source of replication.

• During elongation, a primer sequence is added with complementary RNA nucleotides, which are then substituted by DNA nucleotides.

• During elongation the leading strand is made constantly, while the lagging strand is made in portions called Okazaki fragments.

• During termination, primers are detached and substituted with new DNA nucleotides and the backbone is stuck down by DNA ligase.

Purpose of DNA replication:

The purpose of DNA replication is to produce two duplicate copies of a DNA molecule. This is essential for cell division during development or repair of damaged tissues. DNA replication ensures that each new cell receives its own replica of the DNA.

If a stimulus plus a response results in a satisfying outcome, the probability of that response occurring again ________.


127=7 (mod n) means when 127 is divided by n, the division leaves a remainder of 7.

The statement is equivalent to
120=0 (mod n), meaning that n divides 120.

All divisors of 120 will satisfy the statement because 120 divided by a divisor (factor) will leave a remainder of 0.

Factors of 120 are:
n={1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120}, |n|=16.
You can count how many such values of n there are, and try to check that each one satisfies 127=7 mod n.
