The oceans cover about 70 percent of the Earth's surface. Ocean water contains salts and we say that ocean water has a certain s
Veronika [31]

Answer:

The salt in the oceans comes from weathering and the erosion of the earth's crust.

Explanation:

The weathering can be described as the breaking down of rocks.

During the weathering of rocks, minerals will be dissolved from the land and salt is one of them. These minerals (salt included) will then be delivered into the oceans by erosion of the Earth's crust.

Erosion can be aided by wind, ice or water. Erosion removed weathered materials. When these weathered materials are removed, new materials (rocks) will be exposed to weathering thereby promoting continuous weathering processes

Glacial episodes are an example of _______.
dybincka [34]
I think the correct answer from the choices listed above is option A. Glacial episodes are an example of a positive feedback. Each glacial period in the Earth is subjected to a positive feedback which makes each period more severe. Hope this answers the question.

What other playing practices may lead to soil loss?​
stepladder [879]

Answer:

1. Wind

When strong winds blow, the topsoil along with the organic matter is carried away by the wind. This happens more often when the land is not covered with grass or plants. Such conditions are very common in desert and semi-desert regions where strong winds blow very frequently.

2. Water

When it rains in the hilly areas, the soil gets washed away towards the plains. The running water deposits the mineral-rich soil in the riverbed and over the years this deposition of soil can change the course of the river. This can lead to floods which cause the destruction of life and property. Water erosion leads to loss of agriculture potential.

3. Overgrazing

When cattle are allowed to graze on the same field repeatedly, all the available grass, including the roots are eaten by them. This makes the topsoil vulnerable to wind and flowing water, leading to soil erosion.

4. Deforestation

Humans have taken land from the forest to cultivate in order to feed the ever-increasing population and to build houses, industries, etc. Cutting down of trees on a large scale for these purposes is deforestation. The roots of trees hold the soil together, thus preventing the soil from getting uprooted. When large areas of the forest are cleared, the topsoil gets eroded by wind and flowing water.

Write an essay that details the structure and function of a eukaryotic cell, how its cell membrane functions, and details of how
Marysya12 [62]
  The structure of the eukaryotic cell is as follows: It is seperates into many different "compartments" or what we call organelles. Each organelle carries out a different function. The different organelles include: mitochondria, nucleus, endoplasmic reticulum, ribosomes, golgi apparatus, vesicles, peroxisomes, etc. 

The structure is enforced by intertwining fibers known as microtubules and microfilaments. The membrane is composed of millions of phospholipids that are amphiphilic (comprised of a hyprophilic phosphate head as well as a hydrophobic fatty tail) that seperate the cells internal environment with the outside space. Spread throughout and across the membrane are thousands of different proteins that allow certain molecules to pass in and out of the cell as well as to bind different ligands to stimulate cellular responses. 

Mitosis and meiosis are both stimulated by different factors. Meiosis by fertilization of an egg cell from a sperm cell while mitosis can be signaled by a variety of hormones, protein concentration within the cell, size, etc. Regardless, each process requires the chromosomes in the nucleus to disperse into their loose forms which allows the genes to be copied by a variety of enzymes and ensure that every cell division will yield two genetically identical cells. After the newly copied chromosomes are formed, they condense once again and a large array of microtubules (as mentioned earlier) help bind to these chromosomes and pull them in opposite directions towards the poles of the single cell preparing to divide into two daughter cells. Eventually, the formation of two completely new cells occurs (known as cytokinesis) and the process is complete.
