Answer: All fingers, toes, feet, and palms are covered in small ridges. These are raised portions of the skin, arranged in connected units called dermal, or friction, ridges. They help us with our grip on objects that we touch. When these ridges press against things, they leave a mark, an impression called a fingerprint.
Explanation:
“Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis. During the process of photosynthesis, plants release oxygen into the air. People and animals need oxygen to breathe.” -http://www.mbgnet.net/bioplants/food.html

Answer:
B. Ecdysozoa.
Explanation:
Ecdysozoa is the large group of animals that undergo the process of ecdysis which can regularly shed their outer skin made of the cuticle. This process of shedding the outer skin is also known as molting which is observed in the species of the nematodes and the arthropods.
In the given question, since the new species shed their outer skin which is a characteristic feature of the Ecdysozoa, therefore, the new animal species belongs to the Ecdysozoa.
Thus, Option-B is the correct answer.
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
