Because we are moving with it at the same speed but because that isn’t an answer choice it is probably C
Answer/Explanation:
Normal cell division is a very controlled process.
There are several checkpoints where the cell ensures the cell is:
- receiving the correct signals to divide
- that the environmental conditions are favourable for the cell to divide
- that there is no damage to the DNA.
However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.
Frequency is the term that describes the number of waves passing a point during a certain period of time, frequency is also measured in Hz (hertz).
Answer:
W - Facilitates movement of air by expansion and contraction, X - Traps dust and helps to filter inhaled air, Y - Prevents the wind pipe from collapsing, Z - Help in exchange of gases.
Explanation:
Diaphragm is the muscle that separates the thoracic cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when breathing air in. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. The rings of cartilage making up the trachea allow it to remain open to air at all times. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.
D) six because amino acids are coded by three bases each which = a codon which codes for an amino acid
