By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.
Answer:
This happens due to both refraction and reflection. You're able to see the "red" on the apple because the light reflects off of it and into your eyes thus making the color visible.
Answer: Chemical bonding
Explanation: Bonding by sharing electrons is known as covalent bonding and bonding by transferring electrons is known as ionic bonding. Both are a type of chemical bond that bond elements together into molecules.
The best answer is A.
The lytic cycle is considered the main cycle in viral replication. Once the viral DNA enters the cell, it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes.
The host cell's DNA is destroyed and the virus takes over the cell's metabolic activity and begins to use the cell's energy for its own propagation and within a short while, when the cell gets overcrowded with the viral progeny, the original virus releases enzymes to break the cell wall. The cell wall bursts. This process is called lysis. The new viruses are then released.
<span>Traction
The question pretty much defines the term "traction" as used in orthopedic medicine. There are two main types of traction, skin traction and skeletal traction. If traction is used, it is generally used in conjunction with some other form of treatment.</span>
