What is one cause of long-lasting climate change?


A. Volcanic activity

B. Earth’s elliptical orbit

C. Earth’s rotation

D. The Sun’s elliptical orbit

Answers

A. Volcanic activity

You can approach this question in two ways:

One:
when volcanos erupt (called volcanic activity), they will expel enormous amounts of soot, rock, smoke, and other materials into the air. This material, if light enough, floats around in the atmosphere and can block the sun. The CO2 and other greenhouse gases produced can also contribute to global warming

Two:
Notice how volcanic activity is something that happens randomly and ‘rarely’. However, answers B, C, and D happen all the time. Earth is always spinning, it’s also always rotating around the sun. The sun also never stops moving: its main motion is from revolving around the Milky Way. Thus, it makes sense to choose the one random, rare event. This is because we only see long-lasting climate change occasionally, and thus it can’t be something ordinary like earths rotation.

Alternative Title: primary plant succession

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

Primary succession

Primary succession

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.

QUICK FACTS

RELATED TOPICS

Ecological succession

Pioneer species

Lava-sterilized landscapes, newly formed sand dunes, and rocks either deposited or scoured by retreating glaciers are examples of settings in which primary succession often occurs, because these places either lack soil or their soil cannot sustain life. On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not grow tall but do reproduce quickly. After these plants germinate and grow, they die and decompose, and their remains create pockets of soil in which other plants, as well as fungi, can become established. Over time, such fast-growing vegetation covers more and more of the island, and seeds from other, hardier, taller-growing plants arrive on the wind or are transported by birds that begin to use the island as a stopover during migration.

Surtsey

Surtsey

Surtsey, a volcanic island off the southern coast of Iceland, emerged from the Atlantic Ocean in a fiery eruption in November 1963. Shortly thereafter plants such as sea rocket (Cakile arctica), sand ryegrass (Leymus arenarius), oysterleaf (Mertensia maritima), and seaside sandplant (Honckenya peploides) colonized the island. Much of Surtsey's vegetation is composed of lichens and mosses. However, some higher plants such as the dwarf willow (Salix herbacea) and tea-leaved willow (S. phylicifolia) have grown on the island since the 1990s.

ARCTIC IMAGES/Alamy

These new arrivals shade out sun-loving grasses, shrubs, and other pioneer species, and their cast-off parts decay and add to the soil, altering it by mixing with soil particles left by the decay of earlier plants. More plants and animals arrive (the latter rafting over on flotsam or flying from nearby islands or the mainland), and some become established on the island. The ecosystem changes with each new arrival. Over several decades, the biological community transitions from collections of pioneer and intermediate species to a climax community—that is, a relatively balanced ecological stage whose ecological structure and species composition are far less volatile than those of earlier stages.

Which of the four factors that affect evolution apply to the finches that the Grants studied? Use
evidence from your research to support your answer. (15 points)

Answers

Answer:

Natural Selection in Real Time

"When we made the comparison between the size of the offspring generation and the population before selection, we found a measured, evolutionary response had taken place and it was almost identical to what we had predicted."

-Peter Grant

Darwin thought that evolution took place over hundreds or thousands of years and was impossible to witness in a human lifetime. Peter and Rosemary Grant have seen evolution happen over the course of just two years.

The Grants study the evolution of Darwin's finches on the Galapagos Islands. The birds have been named for Darwin, in part, because he later theorized that the 13 distinct species were all descendants of a common ancestor. Each species eats a different type of food and has unique characteristics developed through evolution. For example, the cactus finch has a long beak that reaches into blossoms, the ground finch has a short beak adapted for eating seeds buried under the soil, and the tree finch has a parrot-shaped beak suited for stripping bark to find insects.

The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.

The first event that the Grants saw affect the food supply was a drought that occurred in 1977. For 551 days the islands received no rain. Plants withered and finches grew hungry. The tiny seeds the medium ground finches were accustomed to eating grew scarce. Medium ground finches with larger beaks could take advantage of alternate food sources because they could crack open larger seeds. The smaller-beaked birds couldn't do this, so they died of starvation.

In 1978 the Grants returned to Daphne Major to document the effect of the drought on the next generation of medium ground finches. They measured the offspring and compared their beak size to that of the previous (pre-drought) generations. They found the offsprings' beaks to be 3 to 4% larger than their grandparents'. The Grants had documented natural selection in action.

While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that have the same size beaks. These factors together can add to the development of new species.

The Grants return each year to Daphne Major to observe and measure finches. They have been collecting data on the finches for over 25 years and have witnessed natural selection operating in different ways under different circumstances.

Importance of plants from an economic, nutritional, environmental and medicinal point of view


Please be correct answer, and if you do not know not with this!​

Answers

Answer:

Plants are extremely important in the lives of people throughout the world. People depend upon plants to satisfy such basic human needs as food, clothing, shelter, and health care. These needs are growing rapidly because of a growing world population, increasing incomes, and urbanization .

Plants provide food directly, of course, and also feed livestock that is then consumed itself. In addition, plants provide the raw materials for many types of pharmaceuticals, as well as tobacco, coffee, alcohol, and other drugs. The fiber industry depends heavily on the products of cotton, and the lumber products industry relies on wood from a wide variety of trees (wood fuel is used primarily in rural areas). Approximately 2.5 billion people in the world still rely on subsistence farming to satisfy their basic needs, while the rest are tied into increasingly complex production and distribution systems to provide food, fiber, fuel, and other plant-derived commodities .

Medicinal plants have been used in healthcare since time immemorial. Studies have been carried out globally to verify their efficacy and some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum. This paper discusses the role, contributions and usefulness of medicinal plants in tackling the diseases of public health importance, with particular emphasis on the current strategic approaches to disease prevention. A comparison is drawn between the ‘whole population’ and ‘high-risk’ strategies. The usefulness of the common-factor approach as a method of engaging other health promoters in propagating the ideals of medicinal plants is highlighted.

- The process happens due to environmental activity

- It takes a relatively long period of time.

- Excessive warmer temperatures in a region have caused rabbits with longer fur to slowly disappear.

Selective Breeding

- Organisms do not choose to thrive but are selected because they are best adapted to the environment.

- A Labradoodle is created by scientists to be hypoallergenic but still look like a Labrador.

- It takes place over a relatively short period of time.

- Humans have a decision in the outcome of the offspring.

- Apples have gotten much larger over the last 30 years due to customer demand

Explanation:

From the above, I have been able to place them in their respective categories.

Natural selection simply has to do with nature. It is a process in nature that leads to the better adaptation of organisms to survive and reproduce in their environment. This type has to do with the natural environment. As nature plays out, it can take longer time and the environment can affect survival rate. Natural selection can lead to speciation.

Selective breeding can also be referred to as artificial selection. This process has to do with the input of man in developing new organisms that possess desirable characteristics and that can adapt to a specific environment. In other words, humans control and decide the outcome of the species that are reproduced. Such breeding process take relatively short time.
