Natural selection. The trait that is unfavorable to the baby giraffe's survival will cause the death of giraffes with that specific gene that is responsible for a short neck vs a long neck. Natural selection causes traits that help the survival of the species will be carried throughout generations while unfavorable traits will be lost.
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.
Answer:
The correct answer is c. are relatively larger than humans.
Explanation:
The olfactory bulbs of the sheep are two or three times larger than humans, and therefore, they provide them a greater sense of smell, which in their case, is indispensable for surviving. This serves them for finding food, as well as finding their babies and other things.
