Answer:
True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.
Explanation:
- An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
- Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
- Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.

Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
Answer:
<h3>Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms. ... Humans play a major role in the carbon cycle through activities such as the burning of fossil fuels or land development.</h3>
I think the answer is A because direct sunlight causes dyes in clothes to fade quietly.
