Answer:
· Fermentation does not generate any additional energy, however, NAD+ is regenerated. In the presence of oxygen, pyruvate is oxidized and acetyl CoA is formed, which feeds into the citrate acid cycle and the complete oxidation of glucose.

Answer:
The possible fate of the cell that it may turn cancerous.
Explanation:
The cells present in the body generally work in harmony. However, if a cell attains a mutation, it can make it proliferate in the case when it should not do, and make it thrive in the case when other cells are dying. Due to proliferation, the unusual cell produces more abnormal cells also known as cancerous cells. These cancerous cells become more favorable in comparison to the normal cells due to the phenomenon of natural selection. These cells eventually result in a lethal form of tumors.
In the normal cells, the destructed gene or the damaged cells get repaired easily, in case if the damage is worse the cell dies. A protein known as p53 helps in repairing damaged cells or kills them if the damage is too severe. But in the case of cancer cells, the p53 protein does not work appropriately as they possess a mutated or changed form of p53 protein. Thus, in the case of cancerous cells, the rate of repair lags behind the rate of mutation, which makes the cancer cells thrive and increase in numbers resulting in further destruction.
After the cerebellum receives proprioceptive information from muscles carrying out a voluntary movement, where does it send corrective feedback to primary motor cortex and cerebral nuclei.
The cerebellum, also known as the corticocerebellum, has a close connection to the regulation of movement timing, rate, range, length, direction, and strength. The cerebellum receives information from the command neurons and also obtains feedback (afferent) from the proprioceptive terminals of the muscles, tendons and joints regarding what the actual movements produce .
All these information are combined and the correction signals are given to the motor cortex. The motor nuclei of the cranial nerves and spinal cord exert the lowest level of motor control. Through the closed feedback loop, this occurs.

Answer:
conifers: Cones
Explanation:
Conifers have cones (hence their name). Cones are the reproductive structures ofthe conifers: Cones are diploid tissue produced by the dominant sporophyte stage. The haploid gametophyte stage develops and produces gametes inside the cone.
