The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
Producers are typically plants, so I believe the correct answers would be 2, 3, 4.
Answer:
Memory and learning - Cerebrum
General bodily arousal - Cerebellum
Complex mental processes - Cerebral cortex
Connects two halves of brain - Cerebrum
Relax, dream, sleep - Hypothalamus
maintain homeostasis - pons
Regulates body circulation - Medulla
Emotions - Cerebrum
Tells senses - Cerebrum
tells nervous system - Cerebellum
Explanation:
Cerebrum is the largest part of the brain which controls emotion and senses of the body. It controls information of the body. Medulla Oblongata is the part of the brain which is just near the spinal cord. It regulates blood circulation. Hypothalamus is the part of brain which regulates sleep wake cycle of a person.
Explanation:
The exchange of gases between the blood and tissue cells is internal respiration. Finally, the cells utilize the oxygen for their specific activities: this is called cellular metabolism, or cellular respiration. Together, these activities constitute respiration.
