Answer:
They remain in an environment,even as more competitive species arrive
Explanation:
Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.
Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:
- They facilitate environmental change, making an environment more habitable for other species.
- They tolerate a wide range of environmental conditions.
- They are capable of colonizing a barren environment, as in primary succession.
However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.
Answer:
Molecules stop moving at freezing point. Helium has the lowest boiling point. The molecules move very quickly at boiling point.
Explanation:
Heating up- molecules move faster. Cooling down- molecules move slower
Answer:
a. transcription
Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
