The process of natural selection is described in the cartoon.
Explanation:
Natural selection is the mechanism by which an organism survive and evolve.
It is the process in which organism have better adaptation to its environment and live to reproduce organisms with useful traits which are passed on to their offsprings.
In the given cartoon it is observed that green beatles fall prey to the crows as a result their survival chances are minimal. Over the generations they are eaten by crows and eventually their brown counterparts are in majority. This is because the brown colour beatles are safe from the prey, they pass on this trait to their offspring and remains safe and more in population.
The brown colouration in beatles is the Darwinian trait of survival of the fittest for beatles.
The variation in population, mutation or genetic drift causes natural selection.
The one with better adaptation survives and reproduce more viable offspring in the population.
The answer is sympathetic nervous system. Sympathetic nervous system is usually activated during sexual intercourse as a result of fear or anxiety and its activation leads to premature ejaculation in males and lack of lubrication in females.
Answer:
During transpiration, water will evaporate from tiny holes in the surfaces of leaves into the air (the tiny holes are called stomata). As the water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

Answer:
By removing the apices of the plant
Explanation:
A plant can be manipulated into becoming more bushy <u>by removing the apices of its shoots.</u>
<em>A plant hormone called auxin which promotes cell elongation and plays a huge role in the maintenance of apical dominance is usually produced at the tips (apices) of stems. When the tips are removed, auxin production is disrupted, and lateral buds that have been initially suppressed by the auxin production begin to flourish, leading to the plant becoming more bushy.</em>
Hence, to trick the jade plant to become more bushy, just remove apices of the shoots the plant.
Answer:
Anthropoids lived for approximately 0.86% of the total time.
Explanation:
- Anthropoids are the higher developed organisms that includes apes and ape mans.
- The age of earth is 3500 million and anthropoids lived for about 30 million years.
- By the simple calculations we can find out the data in percent which gives us the result nearest to 0.86%.
- That means 0.86% of 3.5 billion year is equivalent to 30 million years (time that was lived by anthropoids).
