Fluorescent minerals contain particles in their structure known as activators, which respond to ultraviolet light by giving off a visible glow. Ultraviolet light is a form of electromagnetic radiation invisible to the human eye. There are two classified ultraviolet wavelengths: longwave and shortwave.

Phototropism and geotropism are controlled by which type of plant growth chemical?
m_a_m_a [10]
The answer will either be auxin or thigmotrope, though it's most likely auxin. Thigmotrope would most likely be for thigmotropism, a plant's response to touch.

The map shows the distribution of wild boars in the United States (shaded area).
fgiga [73]

Answer:

Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.

Explanation:

The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.

According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..

About the other options:

  • <u><em>Wild boars were brought to the United States by humans</em></u><em>.  This is true, but it is not a fact that can be deduced from the information on the map.</em>
  • <u><em>Wild boars have quickly spread through the United States</em></u><em>.  The map does not show this information.</em>
  • <u><em>Wild boars have a high reproductive rate and no natural predators</em></u><em>. The map does not show this information.</em>

How can biotic and abiotic factors in an ecosystem affect population
Tresset [83]

Explanation:

An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem.

These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions.

Oxygen is an inorganic gas that makes up the atmosphere, thus it is abiotic ; it is utilized by animals which undergo cellular respiration to produce energy for life processes. A field mouse may continue to reproduce, increasing the population, and feed on other biotic factors, and aid in  nutrient cycling.
