Answer:
The correct answer is D. involves proteins in plasma membranes.
Explanation:
Animal cells have several types of proteins embedded in their cell membrane. These proteins play an important role in the transport of molecules, cell recognition, and cell communication.
Recognition proteins are a type of glycoproteins present in the plasma membrane that allow one cell of the body to recognize the other body cells by making contact with recognition proteins of other cells. Receptors proteins allow cell-cell communication by receiving extracellular proteins.
These proteins are important for proper growth and development of the cell. Therefore the correct answer is D. involves proteins in plasma membranes.

Explanation:
Animals can actually reproduce sexually and asexually. Animals that reproduce asexually do that through fission, fragmentation, budding, etc.
Some of the animals that reproduce asexually include planarians, sea stars, annelid worms, etc.
In the fertilization process, the male sperm cell and the female egg cell come together.
Sexual reproduction involve the fertilization of egg by the sperm. In asexual, there is no fertilization. Ferns are spore-bearing plants. They reproduce via spores but their spores are not actually blackish.
Answer:
They are intermediate hosts.
Explanation:
Disease-transmitting insects are called vectors.
The life cycle of disease-causing pathogens is closely linked to the biology of the insect that carries it.
The symptoms of gongylonemiasis include hemorrhagic inflammation at the site the pathogen invades, followed by granulomatous tissue development that produces nodules in the invaded organ.
Some diseases transmitted by insects occur in both humans and other mammals because our differences in anatomy and physiology are not very different.
It is unlikely that clinical symptoms will occur in humans if the insect were the definitive host, because our biology is quite different from their biology, and the pathogen would be adapted to fulfill its entire life cycle in their body.
