"In looking at nature, never forget that every single organic being around us may be said to be striving to increase its numbers."- CHARLES DARWIN, 1859 ANSWER BRIEFLY 1. How can natural selection reduce competition between species?(2-3 sentences). 2. How do communities and ecosystems respond to changing environmental conditions? (Answerable only by a scientific terminology (two words) I don't need sentences or paragraph for 2). 3. How do species interact (in the context of ecology ha, so scientific term)?

The Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in 3-5 sentences

Which of the following best explains the connection between increased competition and the evolution of a species by natural selection? Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem. Individuals that have traits that allow them to outcompete others survive better and produce more offspring. Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation. Individuals that must compete for limited resources are more likely to have diseases that cause mutations.

Describe natural selection and give an example of natural selection at work in a population. Please elaborate or explain in 10-15 sentences, please?
True or false: If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
I need help with a biology question, When we say that an individual organism has a greater fitness than another individual, we specifically measure the fitness quotient of that organism if it: lives longer than others of its species. competes for resources more successfully than others of its species. mates more frequently than others of its species. utilizes resources more efficiently than other species occupying similar niches. 5. leaves more viable offspring than others of its species. 1, 3 & 4 1, 2 & 5 1, 3 & 5 1, 2 & 3
