<em>Answer:</em>
<em>The stages of the cell cycle in order are interphase, prophase, metaphase, anaphase and telophase. This process is known as mitosis and is used to generate new cells.</em>

Answer:
Carbon monoxide has much more affinity for the hemoglobin than the affinity of the oxygen to the hemoglobin almost 300 times more, which allows the Hb to bind with carbon monoxide irreversibly. Due to this, the small quantity of CO can also reduce the ability of oxygen transport of the hemoglobin.
Longer exposure of CO to the cHb will lead to reducing oxygen release by the Hb that is bound to oxygen in this T state which causes less oxygen availability. In aerobic oxidation mechanisms like oxidative phosphorylation will eventually stop. It will be shifted to anaerobic cellular respiration. The net production of ATP drastically reduced due to anaerobic glycolysis. Cells will eventually start to die causing the death of an organism.
Answer:
A, C and D
Explanation:
Tumor suppressor genes encode proteins that act to inhibit cell proliferation and thus repress the development of tumors, while oncogenes are genes whose overexpression induce carcinogenesis. Tumor suppressor proteins inhibit tumor growth by repairing errors during DNA replication, by suppressing cell cycle progression and by inducing apoptosis (cell death). A well-know tumor suppressor is the protein p53, which is a transcription factor that triggers antiproliferative cell programs by inducing or inhibiting critical effector genes.
Compounds that are charged or polar (have small opposite charges within the molecule) will dissolve in water - because water is polar.
Answer:
A niche is a role a species plays in the ecosystem. In other words, a niche is how an organism “makes a living.” A niche will include the organism's role in the flow of energy through the ecosystem. An organism's niche also includes how the organism interacts with other organisms and its role in recycling nutrients.
