Why is soil important?  Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.

What is soil erosion?  Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

what human activities are responsible for soil erosion happening at advance rates?     Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion

What are some effects on soil loss?  The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What can be done to prevent soil erosion?   Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

If a 100-pound person played tug of war with a 50-pound dog , how light difference forces affect the results?

Answers

Answer: APPARENTLY YOU CAN battle a lion at the San Antonio Zoo. OK, it's not that kind of battle—it's a tug of war battle. There is a thick rope passing through a hole. On one end, there is a lion cub. On the other end of the rope there could be three professional WWE wrestlers. Who wins? Well, the wrestlers don't win. But there is also some physics here.

It's all about friction

A typical tug of war isn't really about strength—it's about friction. It doesn't matter how strong you are if you don't have enough friction to keep yourself from sliding. Let me show you. Here is a force diagram for two people in a tug of war.

Each puller (person pulling on the rope) has essentially four forces acting on them. There is the downward weight which is balanced by the upward push of the ground. Since the person pulls on the rope, the rope pulls on the person in the opposite direction (this because of the two-ended nature of forces). Finally, there is the frictional force between the person and the ground. If no one is "winning," all these forces add up to zero and the person stays at rest. In order to start moving in the winning direction, the frictional force must be greater than the force from the rope.

ADVERTISEMENT

This "two-ended" nature of forces means that forces come in pairs and are an interaction between two objects. It doesn't matter how hard the person on the left pulls on the rope, this same rope pulls on that person. So if you were to increase your pull to 1,000 Newtons—that same rope pulls on both people. So the key is the other force acting in the horizontal direction: friction.

The maximum frictional force depends on two things. It depends on the types of surfaces interacting (maybe it's the rubber on a shoe interacting with a concrete floor) where some surfaces just have more friction than others. You really can't change this part in a tug of war. The friction force also depends on the normal force. The normal force is the force with which the two surfaces are pushed together. In the case of this simple tug of war above, the ground pushes up with a force equal to the gravitational weight of the person. This means that heavier people will have a greater frictional force acting to help win a tug of war.

Oh, note that in the human vs. lion tug of war the humans are on a different surface than the lion. Who has the advantage? It's probably the lion since she could have uneven ground that would allow her to use more than just plain old sliding friction.

So, it's really about mass

If you have two contestants on equal ground with similar friction materials, mass matters. If the person on the left has half the mass of the person on the right, they will have half the friction. This means that it's pretty tough to beat a heavier puller.

What about the lion? This looks like a young lion—she could have a mass of about 120 kg (up to maybe 182 kg). A typical massive human wrestler might have a mass of around 90 to 100 kg. Three humans will probably have more mass than a single female lion. Probably. The humans should have an advantage in the mass.

It's also about rope friction

Wait! This isn't a normal tug of war. The rope isn't straight. Did you notice that? This can make a big difference in that it can add another frictional force into play. Let me show you how this works with a diagram of the rope as seen from the top where it passes through the glass.

Relate the importance of classifying to a real-life situation you encountered personally.
State that situation here. What have you learned from that situation

Answers

The correct answer to this open question is the following.

The real-life situation I encountered personally was to stereotype people according to the way they looked.

Unfortunately, I stereotype and prejudge people just because of their nationality. And I was so wrong.

Since I was a kid I have heard that immigrant people were not good. That they had a different way of thinking, different culture, and traditions that were not good for the American people.

So when I met this kind of people in school, I was on the defensive side. I was never rude to anyone, just put my "barriers" in front of me and tried to keep my distance.

However, one day during finals, I encounter some problems due to personal issues. I ask help from my friends, all American friends, and they never answered. To my surprise, these people from abroad were there for me and lent me a helping hand when I needed it the most. They treated me well as if I were one of them.

What I learned from that situation was that you never have to judge or stereotype people just because they are not like you. You always have to be open to know different kinds of people and welcome different ideas and cultures to learn more about people.

I promise to never judge people because I do not want other people to judge me without really knowing me.

How does the Ocean’s circulation redistribute the Sun’s energy through the earth system

Answers

Answer: Ocean currents are movements of surface water. Because they cover 67 per cent of the Earth's surface, the oceans receive 67 per cent of the Sun's energy that reaches Earth. It holds onto this heat for longer than the land does and the ocean currents move this heat around, from the tropics to higher latitudes.

Which the following takes the most time?
Meiotic prophase II
Mitotic prophase II
Meiotic prophase I
Mitotic prophase I

Answers

Option D.

The time required then for the complete process of mitotic cell division would lie within the following limits: Prophase, 30 to 60 minutes; metaphase, 2 to 10 minutes; anaphase 2 to 3 minutes; telophase 3 to 12 minutes and the reconstruction period from 30 t'o 120 minutes: total 70 to 180 minutes.

Meiotic prophase I takes more time than other processes of mitosis or meiosis.

What are the phases of meiosis?

Meiosis is a type of reductional division as the chromosome number reduces to half in this type of division. It results in the formation of haploid cells. The process of meiosis takes place in germ cells and gives rise to gametes for sexual reproduction. Each process of meiosis produces four haploid cells.

Meiosis is categorized as meiosis I and meiosis II. Meiosis I gives rise to haploid cells. The prophase I of meiosis I have 5 further stages. These are leptotene, zygotene, pachytene, diplotene and diakinesis.

Meiosis II is comparatively simple and is very much like Mitotic division, except the cells undergoing division are the haploid cells produced by meiosis I. Hence, Meiotic prophase II also takes less time than Meiotic prophase I.

Therefore, the process that takes the most amount of time is the Meiotic prophase I.
