Answer:
The main role of DNA in the cell is the long-term storage of information.The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Explanation:
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.
Cellular respiration describes the process of oxygen and glucose and converting into water and carbon dioxide. Homeostasis is a term which refers to biological processes in which living things must maintain stable and equal conditions for survival. Cellular respiration which uses oxygen and glucose must be able to sustain life by releasing energy which is called ATP, the ATP which is produced enables many biological processes that keeps organisms alive. Cells need energy to grow, move, and function. The process of homeostasis enables cellular respiration to produce enough molecules which can sustain the development of the cell. Without homeostasis cellular respiration would cease to function and without cellular respiration the process of homeostasis would not occur. Homeostasis regulates how much molecules have to be expended in order to produce energy for the process of cellular respiration.
