Asap

A.
They poison populations of primary consumers.


B.
They build up soil deposits on the rocky ground.


C.
They neutralize deposits of extreme acids in the rocks.


D.
They increase the amount of oxygen in the surrounding air.

Answers

Answer:

The correct answer is - B. they build up soil deposits on the rocky ground.

Explanation:

Lichens and mosses are known as the pioneer species as they prepare the particular region for the next stages of succession on the bare volcanic region. Lichens and mosses grow on the bare rocks and secrete acids to break the rocks and start soil production.

The soil deposits produced by breaking the volcanic rocks by secreting acids from mosses and lichens. Even after dying these species leads to thickening of the soil and increase organic matter for the next stages to grow.

Discuss the possible outcome of an epiphyseal fracture in a 14 year old patient compared to a 40 year old one

Answers

Answer:

It could close growth plate in a 14 year old leading to shorter limbs or crooked limbs

Explanation:

Compared to a 40 year old patient, an epiphyseal fracture on a person of 14 years can be a cause for great concern.

The epiphyses are found at the ending of long bones. New bones are produced from here.

A person of 14 years is an adolescent and still at the puberty stage compared to a 40 year old. Such a person is not yet mature. An injury such as a fracture can cause the growth plate to close thereby disrupting the growth of the bone. A fracture through growth plate can cause shorter limbs.

The possible outcome of an epiphyseal fracture in a 14-year-old patient leads to shorter and crooked limbs.

What do you mean by Epiphyseal fracture?

An Epiphyseal fracture may be defined as a combination of a horizontal fracture line through the physis and a vertical fracture line that runs from the growth plate through the epiphysis to the articular surface.

The 14-year-old patient is under adolescence so their bone is not completely formed, while a 40-year-old patient almost completed the adulthood stage, so their bone is completely formed and strengthened, which may reduce the chances of bone adjoining.

Therefore, the possible outcome of an epiphyseal fracture in a 14-year-old patient leads to shorter and crooked limbs.

Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.

What is Coastline?

There are approximately 312,000 kilometers of coasts on the continents of the world (193,000 miles). They have changed positions during geologic time as a result of significant alterations in the relative levels of land and sea.

All coastal regions were impacted by sea level dips brought on by the loss of water from the oceans during glacial advances, according to studies of glaciations during the Pleistocene Era.

The sea level during the last Pleistocene glacial epoch is considered to have been nearly 122 m lower than it is now, exposing a significant chunk of what is now the continental shelf.

Therefore, Engage in water sports like surfing is the coastal location in Florida most likely to do if there are moderate winds and waves along the shore.

Why is the thickest, richest soils tend to be found in areas with both moderate climates and gentle topography?

Answers

Answer:

The environment Is just right to support soil formation.

The thickest, richest soils tend to be found in areas with both moderate climates, and gentle topography is found there to provide better soil formation.

Topographical gradients and directions affect soil moisture and temperature. The steep slopes facing the sun are warm. Sudden soil can erode and lose topsoil as it forms.

Thus, they can be thinner than the flatter soils that receive sediment from uphill areas. Floors vary from one part of the world to another, even from one part of the backyard to another. They are, where they are different in their formation. Climate, organism, relief (landscape), base material, and time are five major factors for interactions that create floors.
