The model above shows the processes of phagocytosis, pinocytosis, and receptor-mediated endocytosis. what common feature is involved in each of these processes?

a) only solid particles are moving into the cell.

b) transport proteins move particles against their gradient.

c) as particles move into the cell, water flows out of the cell.

d) particles moving into the cell involve enclosure in a membrane-bound vesicle.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
