Answer:
Positive feedback is used to build more contractions.
Explanation:
Positive feedback mechanism in humans is also observed during childbirth which is induced by the pressing of the ovarian wall by the baby.
The pressing sensation is passed to the brain via different nerves, and in response, the brain stimulates the pituitary to produce oxytocin.
Oxytocin is responsible for the contractions of the uterine muscles which cause the movement of the fetus towards the cervix, further increasing the stimulus.
The positive feedback loop continues until the baby is born.
The water loss rate in the plant's cells is greater than the water absorption in the cells
Answer: Both Respiration and Burning uses oxygen. Both Respiration and Burning produces energy. Both Respiration and Burning gives out carbon dioxide as the end product.
Explanation: The overall chemical reactions of both Respiration and Burning are the same.
Photosynthesis is carried out in the chloroplasts which contain the green pigment chlorophyll. Chlorophyll is what gives plants their characteristic color and it works by capturing the energy that is in the sunlight that strikes the plant.
Photosynthesis is important to life on Earth because grass uses photosnthesis to produce glucose, which is used within the grass for growth<span>. Subsequently, organisms that consume the grass obtain energy and so on. Therefore, photosynthesis is the process through which energy enters an ecosystem.</span>
