Answer:

Claim 2: Earthworms can respond to light.

Explanation:

Yes, earthworms do not have eyes. However, sensory organs of animals isn't restricted to the eyes alone. Other sensory organs include, ears for hearing, nose for smelling and so on. In terms of response to light, the eyes as a sense organ comes into play. However, the skin is also a sense organ which has the ability to feel the effect of a phenomenon such as as heat or respond to touch. Because light produces heat, earthworms can respond to light through their skin. With their skin they can measure the intensity of light falling in them and adjust depending on their current body temperature.

Therefore, earthworms can respond to light with their skin.

do you think a tyrant is more likely to take over in an oligarchy or in a democracy? Why Do you Think so?

Travka [436]

Answer:

More likely to take over democracy

Explanation:

Looking at the modern political world, it seems much less far-fetched to me now. In democratic nations like Turkey, the U.K., Hungary, Brazil and the U.S., anti-elite demagogues are riding a wave of populism fueled by nationalist pride. It is a sign that liberal constraints on democracy are weakening.

To philosophers, the term “liberalism” means something different than it does in partisan U.S. politics. Liberalism as a philosophy prioritizes the protection of individual rights, including freedom of thought, religion and lifestyle, against mass opinion and abuses of government power.
