When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferenc

Komok [63]

Answer:

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency

Chamber O E Chi-square

A 18 10 $\frac{(18 - 10)^2}{10}$ = 6.4

B 2 10 $\frac{(2 - 10)^2}{10}$ = 6.4

Total Chi-square = 6.4 + 6.4 = 12.8

Degree of freedom = 2 - 1 = 1

Tabulated Chi-square (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

The correct option is c.

AUGGCGUUU which of the following DNA strands could have been the template for this RNA?

Delvig [45]

Answer:

3' TACCGCAAA 5'

Explanation:

Transcription is the process by which a particular DNA sequence (e.g., a gene) is used as a template to synthesize a complementary RNA sequence that grows in a 5′ → 3′ direction. This RNA molecule is usually a messenger RNA (mRNA) which is then used to synthesize a polypeptide chain (i.e., a protein) by a process called translation. The complementary RNA molecule produced during transcription is synthesized according to the base pair rules, i.e., Adenine (A) bases always pair with Thymine (T) bases, while Guanine (G) bases always pairs with Cytosine (C) bases. In RNA, Uracil (U) bases pair with adenine, thereby replacing thymines during transcription.
