In the 1950s, the recruitment of women was open to roles in medicine, communication, logistics, and administration. The roles of women in the CAF began to expand in 1971, after the Department reviewed the recommendations of the Royal Commission on the Status of Women, at which time it lifted the ceiling of 1,500 women personnel, and gradually expanded employment opportunities into the non-traditional areas—vehicle drivers and mechanics, aircraft mechanics, air-traffic controllers, military police, and firefighters. The Department further reviewed personnel policies in 1978 and 1985, after Parliament passed the Canadian Human Rights Act and the Canadian Charter of Rights and Freedoms. As a result of these reviews, the Department changed its policies to permit women to serve at sea in replenishment ships and in a diving tender, with the army service battalions, in military police platoons and field ambulance units, and in most air squadrons.

What charter directly affected a women's right to serve in the CAF?
Answer: Canadian Charter of Rights and Freedoms

In 1936 the US Patent Office declared Bell first on its list of the country's greatest inventors, leading to the US Post Office issuing a commemorative stamp honoring Bell in 1940 as part of its 'Famous Americans Series'. The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf. The Bell stamp became very popular and sold out in little time. The stamp became, and remains to this day, the most valuable one of the series.

In which city was the stamp officially released?
Answer: Boston

Bacterial growth follows four phases. When a population of bacteria first enter a high-nutrient environment that allows growth, the cells need to adapt to their new environment. The first phase of growth is the lag phase, a period of slow growth when the cells are adapting to the high-nutrient environment and preparing for fast growth. The lag phase has high biosynthesis rates, as proteins necessary for rapid growth are produced. The second phase of growth is the log phase, also known as the logarithmic or exponential phase. The log phase is marked by rapid exponential growth. The rate at which cells grow during this phase is known as the growth rate (k), and the time it takes the cells to double is known as the generation time (g). During log phase, nutrients are metabolised at maximum speed until one of the nutrients is depleted and starts limiting growth. The third phase of growth is the stationary phase and is caused by depleted nutrients. The cells reduce their metabolic activity and consume non-essential cellular proteins. The stationary phase is a transition from rapid growth to a stress response state and there is increased expression of genes involved in DNA repair, antioxidant metabolism and nutrient transport. The final phase is the death phase where the bacteria run out of nutrients and die.

How many phase are in the growth of bacteria?
Answer:
four phases
