Answer:
In quiet breathing inspiration involves muscular contractions and expiration is passive.
Explanation:
Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.
During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.
During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.
Recall that a period is horizontal, and a group is vertical.
So if cobalt is moving "down" a period, it would be most logical to say that it would be Ni, or nickel. It could also be Copper, Zinc, Gallium, and so on. Make sense?
No, the answer is false.
A salad would be an example of a mixture, as it is a blend of tomatoes and lettuce.
A salad would be considered a heterogeneous mixture (you can see its different components).
The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.
Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:
• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),
• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and
• Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)
