Answer:
Endocytosis is a form of active transport hence require enegry powered by ATP. The amoeba needs to change shape and engulf and envaginate the particle and then use vessicle transportation to get the materials into the cell. This requires that the cytoskeleton - composed of tubules and filaments - contracts and relax accordingly. This requires energy by ATPs just like the myosin and actin of muscle.
Phagocytosis, another form of endocytosis, is used by some cells such as immune cells to engulf foreign material and then destroy them by use of lysozymes. This is how phagocytes protect the body from invaders.
Answer:
d. both organisms have different ways of forming their lungs.
The presences of myelin allows an axon to conduct their signals rapidly
Answer:
Earth radiates infrared radiation.
Incident infrared radiation is blocked.
Infrared radiation is blocked and heats Earth.
Visible and ultraviolet radiation heat Earth.
Explanation:
When the sunlight enters earth's atmosphere, it has short wavelength but after hitting the earth surface, it has long wavelength which allow very less solar radiation by the clouds and greenhouse gases to go into the atmosphere and as a result the earth heat up. if the greenhouse gases are increased in the atmosphere so more heat is blocked by these greenhouse gases and as a result global warming occur.
The missing part of the question is as follows:
Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.
Answer:
1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.
Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.
2. The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.
Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.
3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:
Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.
