During the growing season, a balanced fertilizer, which has been diluted to 1/4 strength, can be added to the water for each watering. (A balanced fertilizer is one that has roughly equal proportions of Nitrogen, Phosphorous, and Potassium. A 10-10-10 fertilizer diluted to 1/4 strength is ideal.)
Q: How many animals are used each year in U.S. laboratories for biomedical research?A: It is estimated that more than 25 million vertebrate animals (animals with a skeleton made of bone) are used annually in research, testing, and education in the United States.
Only about 5% of the animals are monkeys and other primates. Use of dogs and cats is rare.â Because rodents and birds are not covered under the Animal Welfare Act, they are not counted in government statistics; therefore, the exact number of animals used in psychology research is unknown.
