The air puff is the Unconditioned Stimulus
An air puff is "unconditioned" and will naturally require the rabbit to blink
Unconditioned Stimulus - Air Puff
Unconditioned Response - Blinking due to Air Puff
Conditioned Stimulus - Light
Conditioned Response - Blinking due to Light because it is paired with Air Puff
<u>Given:</u>
Present population of bison = 3652
Maximum growth rate = 0.28
<u>To find:</u>
The population of bison after one year.
<u>Solution:</u>
The future population can be calculated with the help of the following formula,

where
is the future population,
is the present population, r is the growth rate and n is the number of years.
On substituting the given values in the formula we get,


Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
Answer:
This question seem incomplete
Explanation:
This question seem incomplete. However, if the strand of the second fragment is what is provided above, then the answer is <em>51</em>
This strand/fragment is definitely a DNA strand because of the absence of uracil (U) or because of the presence of thymine (T). The four bases in a DNA are adenine (A), Thymine (T), cytosine (C) and Guanine (G). These bases also bind to one another in the pattern described below
A ⇆ T
G ⇆ C
Hence, the adenine (A) on one strand can only bind to thymine (T) on the complementary strand (and vice versa) while the guanine (G) on one strand can only bind to cytosine (C) on the complementary strand (and vice versa).
Hence, the letters seen is the question are representations of bases in a DNA strand/fragment. The number of letters/bases here are <em>51</em>
