Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
Answer:
increases its ability to resist predation because the snails that eat it die
Answer:
The wind moves from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses
Explanation:
Relationship between wind speed and direction to air temperature:
wind flows from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses.
A. The land air will heat up more during the day. This is because the land has a lower specific heat capacity than water, hence increases a lot more rapidly in temperature than the sea when the sun comes up.
B. The air packet over the land will cool down more rapidly at night due to the lower specific heat capacity of land when compared to the sea.
