B. larger and more complex
Explanation: As the environment became more unpredictable, bigger brains helped our ancestors survive.
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:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.
