Answer:
The answer is D. Taiga
Explanation:
The taiga biome is also recognized as a coniferous jungle or boreal jungle.
Often times these biomes are extremely wooded with cone-bearing needle-leaved or scale-leaved evergreen trees.
Answer:
The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
Explanation:
Red blood cells transport oxygen throughout the body platelets aid in blood clotting and white blood cells help destroy and remove old cells and foreign substances. This is an example of how cells origin from the same cell (hematopoietic cell in the bone marrow) and then differentiate.
Hematopoietic stem cells are blood-forming stem cells. During hematopoiesis the hematopoietic stem cell divides via mitosis. As a result of mitosis, one daughter cell remains in the bone marrow to continue renewing the hematopoietic stem cells pool while the other goes through next stages of development. Maturate blood cell (red, white or platelet) to leave the bone marrow and enters the circulation.
Asteroid impact
Volcanic eruptions
Explanation:
Asteroid impact and volcanic eruptions are two common events that could lead to a mass extinction.
A mass extinction is an abrupt decrease in life on earth due some catastrophic event.
- The collision of a large bolide on the surface of the earth is a catastrophe in itself.
- The collision and its aftermath have destructive consequences on life.
- The force of the collision can reverberate in form of vibration throughout the earth.
- It can cause heating of the earth surface.
- Volcanic eruptions can become global phenomenon that upsets the earth balance.

Coenzymes
Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions.
Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.
