What are some differences between bone cells and muscle cells?

As the University of Hamburg explains, osteocytes are comprised mainly of collagen and calcium phosphate. Collagen is the rubbery material that allows bones to bend while calcium phosphate is the rigid material that gives bone its strength. The rigidity of calcium phosphate contributes to the shape of the entire musculoskeletal system and allows sites where muscles can attach.\nAccording to Wikipedia, myocytes are tubular cells which make up various kinds of specialized muscle cells. Unlike osteocytes, many myocytes provide many functions throughout the body in various organ systems. The major..

What part of a plant stores food?

The stem is the main stalk of a plant that not only stores food but also conducts it to other parts of the plant. The stem conducts water and minerals throughout the rest of the plant as well. Though plants produce their own food through photosynthesis, they also need to store food for winter when there is less sunlight. Different plants store different amounts in their stems and roots. Annuals tend to store less food, while biennials store more food because they require two growing seasons to complete a life cycle.

What is the function of the fontanels?

By the time an infant reaches 19 months of age, all fontanels should have ossified. Babies have two fontanels: the anterior and the posterior. The posterior fontanel closes within the first few months of life, while the anterior one closes much later. If the fontanels close too early, the baby's brain cannot grow in that direction and will grow in another direction, causing misshaping of the head.\nDoctors can tell if a baby is dehydrated by feeling the fontanels. A sunken fontanel indicates that the child needs fluids.

What is the tensile strength of mild steel?

Ultimate tensile strength is an intensive property, and its value does not depend on the size of the material undergoing strength testing. Variables that do affect UTS are the way the mild steel is treated: whether it has been hot or cold drawn, hot or cold rolled or undergone heat treatments, such as annealing. Surface and internal defects, such as inclusions, reduce the UTS of a material.

What is the scientific classification of an amoeba?

Specifically, amoebas are part of the phylum Amoebozoa, as described by Max Lühe in 1913. In 2002-2003, they were placed into the kingdom Protozoa by Thomas Cavalier-Smith. They are also classified under the domain Eukaryota, as described in 1998 by Cavalier-Smith. The species or genus was first described in 1822 by Bory de Saint-Vincent and later added to the family Amoebidae. There are four major subspecies of amoebas identified as of 2014.

What is transported soil?

Several types of transported soils exists, including colluvial, alluvial, glacial and aeolian. Colluvial soil is transported by gravity. Alluvial soil is moved by running water. Glacial soil is formed from the interaction of ice and snow. Heavy ice masses push glacial soils from one place to another. Aeolian soil is moved by wind. This soil can be classified into dunes or loess.

How much skin does a human shed in a lifetime?

The skin is the body's largest organ and is made up of water, proteins, lipids and different minerals and chemicals. Its job is to protect the body from infections and germs. The skin regenerates itself about every 27 days. The stratum corneum is the outer layer of dead skin cells that used to exist in the epidermis. The epidermis is the outer layer of the skin and is also the thinnest layer. It is responsible for protecting the body from the environment.

How many days are in a year without weekends?

In non-leap years, this calculation process is simple. As there are 52.14 weeks in a year and two weekend days in each of them, simply multiply 52.14 by 5 to get 261 (when rounded up).\nThere are a number of reasons why this information would be useful, the most important of which is in determining the number of business days in a year. This is often an important component of planning a company’s calendar year. Obviously, this is particularly important for non-retail companies that work strictly on business days and never operate on weekends. It is important to note that this figure does not..

What is Micrococcus roseus?

Aside from human skin, it also likes to live on meat and dairy products, or in soil and water. It is not a serious pathogen for humans. If an individual is immune compromised, though, it can become opportunistic, reports Schenectady County Community College. This organism is frequently found in the lab for academic study and use.

How do you calculate cycle time?

Process time refers to the time required to convert the raw materials to the finished product. Inspection time refers to the time period taken to inspect the finished goods with respect to their adherence to the quality requirements. The time taken to inspect a product depends on how complex it is.\nThe move time is the time required to transport the finished and inspected product to the retail shops or directly to the customers from the manufacturing unit. Normally, the move time is measured in days. The move time for different products varies depending on the means of transport used and thei..
