Descending tracts are the pathways by which motor
signals are pass through from the brain to lower motor neurones. Thus, all
the neurones within the descending motor system are classed as upper motor
neurones. The lower motor neurones then directly innervate muscles to produce
movement. Their cell bodies are found in the cerebral cortex or the brain stem,
with their axons remaining within the CNS.
Hydrogen bonds are classified as weak because they are formed fast, but they also break easily under normal biological conditions.
Weak bonds can be easily broken, but this is extremely important because they are in bold in biological systems. For example, they help to decide and stabilize the shapes of water molecules.
B , because there is more than one path of energy coming from the plants but if it’s not B then it’s A because arrows that are all over the place is what makes it a web
Answer and Explanation:
Running or jogging comes under the category of aerobic training/exercise. By definition, aerobic exercise means that the person is training her/his body in the presence of excessive oxygen. So, metabolically speaking, the person is relying on availability of oxygen to carry out metabolism which is mainly about production/supply of energy (ATP) by the breakdown of food in the presence of oxygen. This process is also known as cellular respiration. So, if a person is doing aerobic exercise (running), s/he needs more energy to keep doing the exercise. Typically, aerobic exercise produce more energy (32 molecules of ATP) as compared to anaerobic process (2 molecules of ATP) per reaction run. Thus, In the process of aerobic exercise, the lungs will respire faster to allow more diffusion of oxygen in the blood. Then, this oxygen will be transported to all body by heart pumping and then oxygen enters the cells. Once oxygen is entered, it acts as terminal electron acceptor in a process known as oxidative phosphorylation. This process takes plance in the mitochondria and produces 32 molecules of ATP per reaction.
