Answer:

The correct answer is: A) conditioned response.

Explanation:

These options all refer to different elements of Classical Conditioning - a type of learning in which a biologically potent stimulus is paired with a formerly neutral stimulus.

The conditioned response refers to the <u>learned response to the formerly neutral stimulus</u>. In this example, Grace's whistles are the conditioned stimulus, and Khaleel's sudden squirming and giggling is the conditioned response.

An unconditioned response to an unconditioned stimulus refers to the natural response towards a stimulus.

Answer:

C. conditioned response

Explanation:

A conditioned response is a learned response to a stimulus that was previously neutral. Conditioned responses are an important part of classical conditioning, a learning theory discovered by Ivan Pavlov.

For example, the smell of food is an unconditioned stimulus, a feeling of hunger in response to the smell is an unconditioned response, and the sound of a whistle when you smell the food is the conditioned stimulus.

In this case, the sound of whistle is the condition whistling while the giggling and laughing is the conditioned response

The recognition sites for the restriction enzymes BamHI, XbaI and BglII are G^GATCC, T^CTAGA and A^GATCT, respectively. Which en
Goshia [24]

Answer:

(C) Only BamHI and BglII fragments are compatible.

Explanation:

First we can visualize how the enzymes cut by completing the strand below and cutting where indicated. The three enzymes cut with cohesive ends.

Then we can complete the sense of the strands and serach compatible ends. Keep in mind that we can only join 5 'ends with 3' ends.

BamHI =  G...3'               5'...GATCC  

               CCTAG...5'               3'...G

               

XbaI =      T...3'               5'...CTAGA

                AGATC...5'               3'...T

BglII =       A...3'              5'...GATCT

                TCTAG...5'              3'...A

In bold, leave the bases that remain in single strand and must be compatible with those of the other end.

To be compatible they must be complementary bases. A with T and C with G.  

Now you can see that only BamHI fragments are compatible with those of BglII.

Suppose a particular glacier covers 100 km^2, and it loses 30 cm of depth in a decade. Approximately what volume (km^3 ) is lost
meriva

Answer:

0.03 km^3

Explanation:

First convert the 30 centimeters into kilometers. This will give you 0.0003 km because 1 km is 100,000 cm. Next multiply 100km^2 by 0.0003km which will give you your answer or 0.03 km^3.
