Answer:
3. into ice, which is denser than liquid water.
Explanation:
Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring water molecules. Structurally, both oxygen and hydrogen atoms pulls the electon towards themselves.Thus both atoms share electron by covalent bonding.
However, because oxygen has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called hydrogen bonding .
The orientation of hydrogen and oxygen molecules from dipole -dipole interactions of hydrogen bonding makes the oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid water where they were aggregated. Thus from the question option C is correct.
Answer:
Carcinoma.
Explanation:
These tumors form from epithelial cells, which are present in the skin and the tissue that covers or lines the body's organs. Carcinomas can occur in the stomach, prostate, pancreas, lung, liver, colon, or breast.

The cerebral cortex plays a major role in all of the following except d. circadian rhythm
The cerebrum is split into the left and right hemispheres, while the cerebral cortex makes up the outer layer of the brain and is comprised of gray matter. Gray matter is made up of unmyelinated neurons.
The cerebral cortex is described as having motor, sensory and association areas, and is involved in thought, memory, perception, awareness, and language. Overall, it is associated with voluntary movement, thus the circadian rhythm, involved in homeostasis and the autonomic nervous system, is unrelated to its function.

Answer:
- T. Natural Reseeding.
- D. Species Diversity
- A. Ecosystem Diversity.
Explanation:
Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.
Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.
