Answer: I think it would be A.
Explanation: Because D is the updraft
Answer:
Presence of inorganic molecules with lightning and intense radiation
Explanation:
This process of formation of organic molecules from inorganic molecules is called abiogenesis. It is believed that this is how the first organic molecules were created in early earth about 3.8 billion years ago. The classic 1952 Miller–Urey experiment attempted to replicate the condition of early earth. They replicated lightning strikes (using electric parks) in a glass with greenhouse gases believed to have been the major constituents of early earth's atmosphere like methane. They were able to form primitive organic molecules from this experiment.
Pollination cycles do not really have any direct effect with the soil. Releasing moisture from leaves does replenish some water needed in the soil that is cycled back through the transport systems of plants but does not hold back soil. Photosynthetic activities only draw up nutrients, minerals, and water from the soil through roots.
Therefore, the often elaborate ROOT SYSTEMS are the answer. This is because the roots hold the plants in the ground (soil) and by this, the plants prevent natural disasters, artificial actions, and/or excess water to wash away soil. The roots help to reinforce the soil and hold it together.
Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small.
explicación:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
