Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is the process in which an organism adapted according to environmental changes for its survival and increase there number by reproduction.
Charles Darwin was first to explain its activities and now it's established as the major process behind the evolution.
Aye aye, primate adapted according to the environment and develop a character for its survival over a period of time. Natural selection is the connection between structure and function.
Thus, the correct answer is - natural selection.
Answer:
Secondary succession after a eruption
Explanation:
Answer: Light can influence gene expression at caterpillar stage which can further influence butterfly wing development. This hypothesis was proved by Thomas Hunt Morgan in 1917 a biologist who conducted studies on butterflies from two different species : <u>Vanessa</u> <u>urtica </u> and <u>Vanessa</u> <u>io </u> caterpillars under red, green, or blue light whereas other caterpillars were kept in the dark. He found that there were differences in color and size of wings of butterflies exposed to different light conditions. Exposure to red light resulted in bright colored wings while exposure to green light resulted in dusky wings. Blue light and dark light resulted in paler colored wings. Also, V. urtica caterpillars reared under blue light and V.io butterflies reared in dark wings developed were larger in size.
Therefore light which is an external environmental factor can influence gene expression which can further influence phenotype of the organism.
Hence in the given situation butterfly would show differences in their wing color if in the caterpillar stage they were grown in dark or bright white light.
The answer is the axillary artery. In human anatomy, it is a large blood vessel that carries oxygenated blood to the side aspect of the thorax, the axilla (armpit) and the upper limb. Its source is at the side margin of the first rib, before which it is called the subclavian artery. After momentary passing the lower margin of teres major it goes to the brachial artery.
