Answer:
Category D
Explanation:
In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.
Answer:
This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
Answer:
LIGHT ENERGY is converted to CHEMICAL ENERGY in the process of PHOTOSYNTHESIS
Explanation:
According to the law of conservation of energy, energy cannot be created nor destroyed but can only be changed from one form to another. This means that no form of energy gets destroyed but only transformed. This is evidently so in so many natural processes including the process of PHOTOSYNTHESIS undergone by plants.
Photosynthesis, which is the way plants obtain their food via sunlight, converts the LIGHT ENERGY of the sun to CHEMICAL ENERGY in glucose produced. Hence, photosynthesis obeys the law of conservation of energy.
