____ is a process by which organisms with characteristics suited to the environment will survive and reproduce. a. natural selection c. evolution b. artificial selection d. organic evolution

Answers

The correct answer is (a) Natural Selection

Natural Selection is the process by which the the phenotype which best suits the environment survives and reproduce. This is because of the differences in the phenotype. The species evolve through a period of time to adapt the environment. The adaptations or the characters are inherited to the next generation over the population. Natural selection acts on the phenotype and is the main key for evolution of species.

What idea is Malthus known for?

Answers

ogy of Human Populations: Thomas MalthusThomas Malthus (1766-1834) has a hallowed place in the history of biology, despite the fact that he and his contemporaries thought of him not as a biologist but as a political economist. Malthus grew up during a time of revolutions and new philosophies about human nature. He chose a conservative path, taking holy orders in 1797, and began to write essays attacking the notion that humans and society could be improved without limits.Population growth vs. the food supply
Malthus’ most famous work, which he published in 1798, was An Essay on the Principle of Population as it affects the Future Improvement of Society. In it, Malthus raised doubts about whether a nation could ever reach a point where laws would no longer be required, and in which everyone lived prosperously and harmoniously. There was, he argued, a built-in agony to human existence, in that the growth of a population will always outrun its ability to feed itself. If every couple raised four children, the population could easily double in twenty-five years, and from then on, it would keep doubling. It would rise not arithmetically—by factors of three, four, five, and so on—but geometrically—by factors of four, eight, and sixteen.
Between 1800 and 2000 the human population increased about six-fold. Has the food supply kept pace? Will there be enough food to support the projected population of 9.2 billion in 2050?If a country’s population did explode this way, Malthus warned that there was no hope that the world’s food supply could keep up. Clearing new land for farming or improving the yields of crops might produce a bigger harvest, but it could only increase arithmetically, not geometrically. Unchecked population growth inevitably brought famine and misery. The only reason that humanity wasn’t already in perpetual famine was because its growth was continually checked by forces such as plagues, infanticide, and simply putting off marriage until middle age. Malthus argued that population growth doomed any efforts to improve the lot of the poor. Extra money would allow the poor to have more children, only hastening the nation’s appointment with famine.A new view of humans
Malthus made his groundbreaking economic arguments by treating human beings in a groundbreaking way. Rather than focusing on the individual, he looked at humans as groups of individuals, all of whom were subject to the same basic laws of behavior. He used the same principles that an ecologist would use studying a population of animals or plants. And indeed, Malthus pointed out that the same forces of fertility and starvation that shaped the human race were also at work on animals and plants. If flies went unchecked in their maggot-making, the world would soon be knee-deep in them. Most flies (and most members of any species you choose) must die without having any offspring. And thus when Darwinadapted Malthus’ ideas to his theory of evolution, it was clear to him that humans must evolve like any other animal.

Because the United States imports about 4 billion barrels of crude every year, at best, the Arctic National Wildlife Refuge could provide us with nearly one hundred years worth of oil. True False

Answers

The given statement is false.

A particular plant species is pollinated by a certain insect species. The insect species depends on the plant species for food. Which term describes how this relationship forms?reproductive isolation

co-adaptation

mass extinction

instantaneous speciation

Answers

A particular plant species is pollinated by a certain insect species. The insect species depends on the plant species for food. This relationship is based on co-adaptation.  

Here co-adaptation refers to the mutual adaptation between the given species(plants and insects) that depend upon each other.
