This is known as the double helix.
There are no directions…
Answer:
triple bonds
Explanation:
One carbon atom forms four covalent bonds with four hydrogen atoms by sharing a pair of electrons between itself and each hydrogen (H) atom.
To solve the question we proceed as follows;
time=distance/speed
distance between the monkeys is 2km=2000m
But the speed of sound= 330 m/s
Therefore the time taken for a howler monkey to get to the other will be:
time=2000/330
=6.1 seconds
The answer is 6.1 seconds
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.
