Answer:
False
Explanation:
Because X-inactivation is random, in normal females the X chromosome inherited from the mother is active in some cells, and the X chromosome inherited from the father is active in other cells.
Answer:
C6H12O6 - glucose.
Synthesis.
Explanation:
Equation showing Photosynthesis
6CO2(g) + 6H2O(l) --> C6H12O6(s) + 6O2(g)
Photosynthesis requires sunlight as a source of energy for plants, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate (organic) molecules, most commonly glucose.
The equation also shows that during photosynthesis, CO₂ gains hydrogen atoms and becomes a sugar/glucose molecule. The synthesis of any molecule requires energy and during photosynthesis this energy is provided by the sun.

Fungi and bacteria are the key decomposers in many ecosystems; they use the chemical energy in dead matter and wastes to fuel their metabolic processes. Other decomposers are detritivores—detritus eaters or debris eaters. These are usually multicellular animals such as earthworms, crabs, slugs, or vultures.
The answer is letter B.
Muscles in animals are often or almost always found in pairs because they need to be able to both push and pull. Pushing and pulling are the basic movements that the skeletal system can perform. It occurs when individuals are lifting, walking, running, among others. Almost all activities need the push and pull motion of muscles to balance out movements. Without this mechanism, we might easily fall over while walking (e.g. hamstrings are pulling back while the quadriceps are pushing forward).
