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.
Currently, estimates of the total number of species range from about 10 million to a billion, but these estimates are tentative, and may be off by many orders of magnitude. By comparison, there are probably between 10 and 30 million species of animals, the vast majority of them insects. The number of scientifically recognized species of animals is about 1,250,000. There are almost 300,000 recognized species of plants.
