How did short term catastrophic events, such as volcanic eruptions and asteroid collisions affect the climate and biosphere?

Answers

Dust particles and debris from the collision float up into the Earth's atmosphere, thus blocking the sun's rays. When volcanoes erupt, they can cause chemical clouds to linger in the atmosphere, also blocking the sun's natural rays

Darwin discovered twenty different species of finches in the Galapagos islands. He hypothesized that as new islands arose, finches colonized the islands and rapidly changed into new species, depending on what food was available on each new island. The rapid formation of many new species, as in this case, is called

Answers

Answer : The correct answer is -

Adaptive radiation.

Adaptive radiation is an evolutionary process that describes rapidformation of new species from a group of organisms that have common ancestral species.

It occurs particularly when group of organisms move to different environmental conditions ( with availability of new resources) that leads to new challenges for the organism, which adapt to it and eventually forms new traits, thereby forming new species.

As per the Darwin's discovery, finches colonized the islands and rapidly changed into new species, depending on what food was available on each new island. This leads to rapid formation of new species.

Thus, it is an example of adaptive radiation.

The answer is adaptive radiation.

Bears and coyotes both consume large plant-eating mammals such as deer. When the deer are in short supply, bears andcoyotes may fight over the prey. This type of biological interaction is called a. Commensalism c. mutualism b. Competition d. rumination

Answers

The answer is competition.

Competition is an interaction between members of the same species or between different species. If resources, such as food, water, sunlight, territory, are limited and several species depend on these resources, then, they must compete with other species to gain the resources. In this example, bears and coyotes depend on deer and when deer population is reduced, bears and coyotes must compete in order to survive.

Answer:

Its competition

Explanation:

Bears and coyotes will fight over the deer if the deer are in short supply so they won't have much deer to consume

The overall population of a species has increased. What could have occurred to allow this to happen?

Answers

Answer: Immigration can be a reason for a overall increase in the population of a species. It is a method by which the species at other place migrate to a different place permanently. The reason to migrate to a different area can be lack of resources, hunting, or any natural calamities. The population of a particular geographical area shifts to another area only because of the problems that does not allows the population to reside there. This makes the population move to another area for their survival.

D. The immigration of the population is greater than the emigration.

Which of the following makes up the dense outer layer of bone?a. compact bone
b. spongy bone
c. bone marrow
d. periosteum

Answers

The answer to the question is

A. compact bone

The answer to your question is the compact bone .

What is some conlusive evidence that organisms of two different species share a common ancestor?

Answers

Well, according to the theory of evolution, the reason that organisms of two different species would share a common ancestor is that way back before evolution really took place, there were species that were all grouped together. After time, these species needed to evolve in order to adapt to the way the environments were changing. For example, dogs and wolves are not the same species, but are related and share a common ancestor, causing them to look alike.
