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 51

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 51

Explanation:

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Ee, Hh, and Bb, that determine if gremlins are evil (E), have hair (H), and biting teeth (B). In order to determine if the 3 genes were linked, a standard testcross was done, and the 1000 offspring ...

Answer:

B. physical anonymity.

Explanation:

Anonymity can be explained in psychological research as a situation whereby the data collected from participants is confidential and cannot be traced to any particular individual.

Deindividuation is known to be a phenomenon in which people engage in seemingly impulsive and sometimes violent acts in situations in which they believe they cannot be personally identified.

In this case, people that are not physically present tend to be more hostile or engaged in some cruel act. This is because they know they can be seen face-to-face, and people will not know that they are the perpetrator of the act.
