Answer:
The finches on Galapagos Islands had different beak
The beaks of the finches changed over time
The Galapagos finches had a common ancestor
Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.
Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
Answer:
B
Explanation:
process of elimination. The other ones were wrong tbh. Also, in natural selection genetic variation/mutations are a HUGE FACTOR according to darwins 3 principles of evolution.
Standard of living refers to the quality, and quantity, of goods and services made available to an individual for his/her consumption. This definition is a general one and is easily understood.
To improve one's standard of living, in accordance with this definition, one needs to be provided with a better quality goods & services , such as advanced electronics and gadgets, or quantity, such as producing more self-care product for consumption.
So how does this conflict with his/her environmental concerns? In order to improve standard of living, there is a few trade offs. To produce more quantity of goods & services, more resources have to be used. This might lead to excessive usage, wastage & depletion of natural resources. For example, to provide more fuel to the society, companies have to extract more & more of fossil fuel. Sustainable usage of natural resources might be a concern, since some types of resources are unrenewable e. g oil & gas.
Production of higher quality products requires advanced state of technology. In the meantime, the use of some technologies aren't exactly environmental friendly i. e it may create pollution. For example, decades ago, manufacturing shirts using traditional methods might not yield consistent results thus the invention of machine helps with increasing the quality, however, results in noise and air pollution. Another example, using air-conditioning instead of hand fan is more effective in coping with hot weather, but greenhouse gas is emitted.
This shows the conflict between environmental concern and the desire to improve standard of living in general.
Hope this helps!
