B. exons
C. introns
D. the genetic code
Answer:
At the stage of progression in the cancer development, the cancerous cells shows out of control growth and invasion of surrounding tissues.
Explanation:
The cancerous cells are genetically mutated, whether it may be carcinoma or sarcoma. They grow in an uncontrolled manner by the process referred to as hyperplasia. In this process, the cells though similar in nature, proliferates to an uncontrolled and huge number with in the tissue, thus depriving the healthy cells of the tissues of essential nutrients. Then comes the stage of dysplasia where more genetic alteration takes place in the cells making it completely different and disoriented. The cells also loses the organizational activity to retain tissue structure and functions.
According to the CDC, tooth decayaffects more than one-fourth of U.S. children aged 2 to 5.Tooth decay is thedamage of the structure of the tooth which is caused by acids that are producedwhen sugar is being broken down by plaque bacteria in the mouth. Tooth decay is the primary cause of tooth loss in children in the UnitedStates.
The correct answer is:
glycolysis, during respiration
Photosynthetic algae create sugars that eventually be broken down during : A. Glycolysis, during respiration
During this process, Algae produced 2 ATP and 2 NADH, which is used in forming energy.
Explanation:
The cleavage down of sugars is called glycolysis. The prefix glyco- means sugar, and the suffix -lysis means breaking down. It's part of a three-step method in respiration, the other two is The Krebs Cycle and Electron Transport Phosphorylation. In the manner of glycolysis, 2 ATP and 2 NADH are designed. Glycolysis is the metabolic pathway that transforms glucose C₆H₁₂O₆, into pyruvate, CH₃COCOO− + H⁺. The free energy released in this manner is used to form the high-energy molecules ATP and NADH.
