What is the name of the thick outer covering around a plant cell?

The structure that surrounds plant cells, but not animal cells, is the cell wall.

The cell wall is a tough and flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. It also functions as a filtering mechanism to make sure that not everything can enter the cell. A major function of the cell wall is to counter pressure, preventing over-expansion when water fills the cell. The materials in a cell wall vary between species. In plants, the strongest component of the complex cell wall is a carbohydrate called cellulose, which is a glucose polymer. Fungi possess cell walls made of the glucosamine polymer called chitin, and algae typically possess walls made of glycoproteins and polysaccharides. Diatoms, however, have a cell wall composed of silicic acid.

How can you tell if your dog dislocated its hip?

It limps. It's leg could be out of the hip socket above or below the socket. The leg may appear longer or shorter than the opposite one, and the dog will not want to put weight on it. There will probably be a space between the hip socket and leg bone. You need to take the dog to a vet if it appears to have dislocated its hip. Get to the vet fast! because over a few days, calcium will build up inside the hip socket making for a much more expensive vet bill and unnessecary hurt for the dog for the rest of his life.

African-American History

What is the Freedman's Bureau?

On March 3, 1865, Congress established the Bureau of Refugees, Freedmen, and Abandoned Lands, which was more commonly known as the Freedmen's Bureau. It was to be in service for only one year but, on July 16, 1866, Congress extended the life of the bureau despite the veto by President Andrew Johnson. The bureau's main focus was to provide food and medical care, to help the freedmen to resettle, to ensure justice for the freedmen, to manage abandoned or confiscated property, to regulate labor, and to establish schools. In many cases, it also provided aid for destitute whites.

The bureau opened 4000 free schools, including several colleges, and educated 250,000 African Americans. By 1870, 21% of African-American population could read.

Although the bureau was successful in its educational goals, it failed in its goal to establish land for the freedmen. The bureau did, however, give 850,000 acres to the freedmen, but President Andrew Johnson revoked the land and gave it to the Confederate landowners.

Consequently, the bureau focused upon employment. It encouraged the freedmen to work on plantations, but this became problematic when the freedmen became sharecroppers and tenant farmers.

Even though there were many problems, the Freedmen's Bureau did help the newly freed African-Americans to get the rights that they had been denied. These included the right to an education, the right to due process, the right to the practice of religion, and the right to contract.

What is a group of kangaroos called?

same answer all 3

A group of kangaroos is called a troop, mob, or herd.

A group of tree kangaroos is called a colony.

There is a misconception that a small group of kangaroos is called a court. "Court" has no reference at all to a group or collection of kangaroos. A "kangaroo court" is quite different, and refers to sham legal proceedings where the outcome is decided more or less in advance, regardless of witnesses and the appearance of genuine proceedings.

Deforestation and Habitat Loss

Why are tropical rainforests near the Equator?

The region around the equator is the tropics (both north and south), so any rainforest around the equator which is in the tropics is a tropical rainforest.

A rainforest can exist (and does exist) outside the tropics. The Pacific Northwest, for example, has the Hoh rainforest.

A "tropical rainforest" is typically hot year round with little temperature change from month to month.

Tropical rainforests are near the equator because the climate there is warm, very wet and constant due to the position of the sun over the equator; it's always directly overhead. The plants that live there thrive in these conditions. There are only two seasons in the tropical rainforests: wet season and dry season.

The rainforests are so wet because whenever it rains, the water collects on the big leaves of the trees and evaporates quickly, forms into clouds and rains down again.

If you have a 1943 cent it's worth 25 to 50 cents in circulated condition.

If you have a 1945 cent it's made of bronze and is worth less than 3 cents.

OTOH if your coin is dated 1943, then it is steel and is worth maybe 25-50 cents depending on how worn it is.


How many legs does an octopus have?

octopuses are widely considered to have 8 legs however they actually have 6 , the other 2 are arms

Not true.

An octopus has 8 tentacles. But marine scientists now believe that only 2 of those tentacles are actually used for walking and moving around. These are called as legs. The remaining 6 are used for feeding and other functions. Hence they are called as arms.

It used to be thought that an octopus had eight tentacles or "arms". Now, scientists are saying that two of those tentacles are legs, so an octopus has two legs. The rest are arms.

Colonial America
Australian Colonial Settlement

What did the early settlers wear?

Boys and girls under the age of seven would have both worn a long dress. The boys wore a cap called a biggin. It was large and tied under the chin. The girls, like the women, wore their hair up in a small cap called a coif. After the age of seven the boys would wear the same type of clothing as the men.

The men generally wore a button up long sleeve, button up shirt with a ruffle around the collar. The pants were short and tied off at the knee.

The women wore ankle length dresses with long sleeves. The Pilgrims of that time did wear some colorful clothing.

Underwear came in the form of a shift, or long shirt. Long stockings were worn with the day clothes. No one wore underpants. Females wore their hair long and in the coif. If a hat was needed it would be placed on top of the coif. Shoes were leather and all cut the same. There was no right or left shoe.

Pica Disorder

What causes a small pea sized hard lump in back of neck on hair line no pain?

Generally speaking, these "pea-sized" lumps are plugged up oil glands (there are a lot in that area)... The skin can over-grow an oil gland, but the glands continues to secrete oil; the gland will swell as the oil builds up --which becomes mixed with the internal skin cells sloughing off the inside wall of the "lump". When this happens, we call them "sebaceous cysts". (a cyst by definition is a fluid-filled sac)... They are not dangerous, but occasionally one will become irritated and sell even more. When it ruptures (usually because you squeezed it) a cheezy-sour smelling material will come out... The material is the oil & internal skin cells I mentioned earlier... The problem with these cysts is that once formed they will periodically swell & drain until a surgeon cuts the sac out. If they don't get ALL of the wall, the cyst will re-form and continue to periodically swell and drain...

What is the best homework help website?

A Word About "Help"

If you mean actual help, then any of the websites are good places to go - if you mean "where can I get someone else to do my work for me?" then WikiAnswers will not be very helpful.

The point of homework is for you to practice, practice, practice so that you will learn how to do the material from school. Even if it seems useless to you now, the things that you learn how to do will help you later - you might not ever need to know those words you have to look up, but you will certainly need to know how to look up information!
