Answer:
An example of passive transport is diffusion, the movement of molecules from an area of high concentration to an area of low concentration. Carrier proteins and channel proteins are involved in facilitated diffusion.
Explanation:
Answer:
Because of the angle of the Earth relative to the sun. The higher the sun is in the sky, the higher the UV radiation level.
Explanation:
So, the lattitudes toward the poles that receive sunlight are at an oblique angle, with that being said, the amount of radiation is spread to a larger area than the equator.
Answer:
Planting trees, CARBON CYCLE, and cooking with gas do not add Carbon dioxide to the atmosphere.
Explanation:
The atmosphere naturally breathes or decomposes carbon dioxide rocks, whereas forest fire takes place and volcanoes erupt.
The atmosphere is naturally decomposed. Human activities like fossil fuel and forest burning, and cement production, also add carbon dioxide to the atmosphere.
Answer:
Disruptive selection
Explanation:
According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.
From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.
According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
