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:
C Differences among temperature, air pressure, and density
Explanation:
Classification of the atmosphere layer will be different based on the temperature, air pressure, and density. Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.
Snow melting would be due to the temperature
Answer:
D
Explanation:
Chromosomal rearrangements are no more likely to occur in mammals than other vertebrates
Translocations and inversions can be extremely deleterious, for example, if the break point is within a gene, that gene would be dysfunctional, or a new harmful fusion gene could be created
Rearrangements are not more likely to occur in mitosis than meiosis
A homozygous deletion for a gene means none of that gene product will be made. If this product is important, this could cause problems for that individual. An individual that is homozygous for a duplication still has a copy of the gene, so while they may face some problems owing to the overexpression of the gene, it is more likely that not having the gene at all will be more problematic (depending on the gene of course!)
Answer: it reflects light from the sun.
