Answer:
Reducir las actividades humanas.
Explicación:
Reducir el uso de combustibles fósiles, el uso de vehículos que funcionen con electricidad y plantar más plantas y árboles son las acciones que propondría para ayudar a que la biosfera y sus ciclos no se vean afectados. La biosfera se ve muy afectada debido a las actividades humanas, por lo que para conservar la biosfera y mantener su ciclo, tenemos que reducir las actividades humanas que causan más daños a la biosfera.
Answer: This is a positive feedback loop.
Explanation:
The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.
These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.
The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.
This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.
It is called an autotroph.
Sunlight is used during photosynthesis for plants to make energy. As we are not autotrophic, we need to acquire energy through plants, or animals that have obtained their energy through plants. When we eat, the glucose and other starches are broken down into monosaccharides, then stored until we need energy (such as walking the dog). When we use energy, the sugars are taken along with oxygen to convert it into energy.
