Answer 1

A cool region underneath cloud cover will have a higher temperature than a region with no cloud cover. The correct option is A.

What is the cloud?

Cloud is a collection of minute drops of water, crystals, and other substances. They are made when the water from earth evaporates and, due to low pressure, it accumulates into a cloud.

The temperature underneath the cloud has comparatively high temperature.

Thus, the correct option is A. a higher temperature than.

Imagine that part of a population of flies is blown from the California coast to an offshore island. The island flies have no contact with the mainland flies for 10,000 years. Then an earthquake rearranges the landscape and the island is rejoined to the mainland. The former island flies can now mingle freely with the mainland flies. If attempts at mating between flies from the two groups are successful and the resulting offspring grow up strong and healthy and have offspring of their own, you could conclude that _____.



Speciation didn't occur over the past 10,000 years


We conclude this, since the two populations could mate (if speciation occurred, there would be no reprodution).

For example, in allopatric speciation which occurs as a result of geographic isolation, the part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations  reach a high level  of genetic divergence. They can no longer interbreed (reproduction between them) which means they become two different species (speciation).

New populations evolve as result of mutation, genetic drift and natural selection.

The process whereby oxygen is depleted by the growth of microorganisms due to excess nutrients in aquatic systems is called ________. dead zoning





Eutrophication (or eutrophication) is a process usually of anthropic origin (caused by man), or rarely of a natural nature, having as its basic principle the gradual concentration of accumulated organic matter in aquatic environments.

Among the impacting factors, contributing to the increasing pollution rate in this ecosystem, are: domestic waste (sewage), agricultural fertilizers and industrial effluents, directly discharged or percolated towards watercourses (rivers and lakes, for example).

what is the tone of the passage? The Monkey's Paw by W. W. Jacobs (excerpt) At the foot of the stairs the match went out, and he paused to strike another; and at the same moment a knock, so quiet and stealthy as to be scarcely audible, sounded on the front door. The matches fell from his hand and spilled in the passage. He stood motionless, his breath suspended until the knock was repeated. Then he turned and fled swiftly back to his room, and closed the door behind him. A third knock sounded through the house. "What's that?" cried the old woman, starting up. "A rat," said the old man in shaking tones—"a rat. It passed me on the stairs." His wife sat up in bed listening. A loud knock resounded through the house. "It's Herbert!" she screamed. "It's Herbert!" She ran to the door, but her husband was before her, and catching her by the arm, held her tightly. "What are you going to do?" he whispered hoarsely. "It's my boy; it's Herbert!" she cried, struggling mechanically. "I forgot it was two miles away. What are you holding me for? Let go. I must open the door." "For God's sake don't let it in," cried the old man, trembling. "You're afraid of your own son," she cried, struggling. "Let me go. I'm coming, Herbert; I'm coming." There was another knock, and another. The old woman with a sudden wrench broke free and ran from the room. Her husband followed to the landing, and called after her appealingly as she hurried downstairs. He heard the chain rattle back and the bottom bolt drawn slowly and stiffly from the socket. Then the old woman's voice, strained and panting. "The bolt," she cried, loudly. "Come down. I can't reach it." But her husband was on his hands and knees groping wildly on the floor in search of the paw. If he could only find it before the thing outside got in. A perfect fusillade of knocks reverberated through the house, and he heard the scraping of a chair as his wife put it down in the passage against the door. He heard the creaking of the bolt as it came slowly back, and at the same moment he found the monkey's paw, and frantically breathed his third and last wish. The knocking ceased suddenly, although the echoes of it were still in the house. He heard the chair drawn back, and the door opened. A cold wind rushed up the staircase, and a long loud wail of disappointment and misery from his wife gave him courage to run down to her side, and then to the gate beyond. The street lamp flickering opposite shone on a quiet and deserted road.
