Answered by answersmine AT 22/10/2019 – 02:35 AM I think the answer is all species evolve from pre-existing species. This was based on Charles Darwin’s Theory of Evolution which he learned during his expeditions.He identified that some fossils have similarities with other existing animals, in which he believed were a part of …Read More »
Which of the following statements about the effects of pollution on marine ecosystems is true? a. Burning fossil fuels causes a direct increase in the temperatures of ocean water. b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic. c. Pollution in marine ecosystems causes a decrease in the formation of algal blooms. d. Addition of warm water has no effect on marine ecosystems
The equation for how temperature changes the resistance R is: R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance. The resistance of the copper wire increases by 18% or by 0.18, so the …Read More »
Answer: The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment. Explanation: Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a …Read More »
In tropical rain forest, the animals will have to deal with higher temperatures and greater rainfall. One example of an adaptation they might need is a thin, water-proof coat. This will prevent heat from becoming trapped inside their fur/hair/feathers, and the water-absorbing coating will allow water to stick to the …Read More »

In evolutionary biology, mimicry is a similarity of one organism, usually an animal, to another that has evolved because the resemblance is selectively favoured by the behaviour of a shared signal receiver that can respond to both. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry evolves to …Read More »
