Answer:

Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called primary tumors or ones that can move called metastatic tumors.

Explanation:

The term primary tumor refers to the original tumor, a place where the tumor first appeared.

Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.

For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.

The basic structure of DNA is called a double helix. It contains two strands, and each strand is produced of nucleotides. Specific sequences of nucleotides make up genes, which provide instructions for cells. The amount of A bases in DNA equals the amount of T bases, and the amount of G bases equals the amount of C bases.

Answer:

Polymers are large molecules with a chain structure that can be linear, branched, and cross-linked. Polymer chains are mainly composed of covalently bonded atoms.

Explanation:

Polymers can be synthesized using  reactants of petrochemical or renewable origin. Polymers can be synthesized in two  methods, by step-growth and chain polymerization. Both ways of polymerization are  random processes during which chains of different lengths are formed.

The basis of step-growth polymerization is the condensation reaction.

Answer:

It is important for the cell to be able to bring necessary nutrients immedriately where it needs to and to be able to dispose of harmful byproducts of the cell process. It is equally important to be able to regulate water concentration.

Answer:

For the first question, you have to first understand how cells work. Cells transport nutrients and water through their cell membrane, and it's their only way of transporting things they need in and out of their interior. Hence, a larger surface area would be best for cells to survive.

You might ask, but then why wouldn't it be better for cells to be bigger if a larger cell membrane is beneficial to their survival? After all, as the cell gets bigger, their cell membrane gets bigger too!

Unfortunately, you'd be forgetting one thing: the insides of the cell, otherwise known as the volume of the cell, grows too. So, it becomes a mathematical question at this point: imagine a cube. If you doubled it's side length, your surface area would grow by 4 times ([tex]2x \cdot 2x = 4x^{2}[/tex]), and your volume would grow by 8 times! ([tex]2x \cdot 2x \cdot 2x = 8x^{3}[/tex])

Hence, if the cell got bigger, it's volume would grow faster than the surface area, and the cell would start to build up carbon dioxide and other waste materials.

This is the main reason why being small helps cells survive. Of course, there are many other reasons, like compactness, efficiency and survivability, but this is the main reason.

Of course, if you're smart, you'd have already discovered one thing: this is exactly the reason for your second question as well. Since a large organism being made of one or few large cells would greatly decrease surface area-to-volume ratio, the efficiency would plummet and the large organism would die. Hence, many small cells would help large organisms maintain homeostasis.

Answer:

lípidos (fosfolípidos y colesterol)

Explanation:

Las membranas celulares están formadas principalmente por fosfolípidos, los cuales son lípidos compuestos por una molécula de glicerol con dos ácidos grasos unidos y un grupo fosfato. Los fosfolípidos se disponen formando una bicapa, dentro de la cual los grupos fosfatos (con mayor afinidad por el agua, es decir hidrofílicos) se orientan hacia el exterior celular y hacia el interior de la célula, mientras que las colas de ácidos grasos (hidrofóbicas, por lo que tiene mayor afinidad por sustancias no polares) se encuentran en la parte interna. Además, la membrana posee otro lípido: el colesterol, el cual tiene como principal función la regulación de la fluidez de la membrana.

Answer: No, I do not think that nuclear power is safe to use. Any radioactivity in general is dangerous in itself. I would not feel comfortable living near a nuclear power plant, due to the radioactivity, the pollution, and the huge health risks of doing so, such as extremely elevated risk for cancer

Answer:

I don't really think nuclear power is safe to use, it's too unpredictable. I would not want to live anywhere near a nuclear power plant on account of the fact that there have been multiple accidents involving nuclear power plants, for example, Chernobyl in 1986, Fu kushima in 2011, and Three Mile Island in 1979.

Explanation:

Pharyngolaryngectomy is an operation to eliminate/remove the larynx (voice box) and the pharynx (the territory at the rear of the mouth and throat). The activity is intense, requiring a general anesthetic and a stay of a little while in medical clinic. Now and then it should be completed in two phases, the subsequent stage being to revamp the structures in your neck however much as could reasonably be expected. This will expect unions to be taken from your chest, back or lower arm.

You should be offered broad pre-operative guiding in anticipation of the deficiency of your voice, in spite of the fact that it is conceivable to recapture a decent measure of vocalization with language instruction. After the activity you should inhale through an opening in your neck which will be a permanent feature.

Answer:

Digesting carbohydrates involves first the starch and glycogen breaking down into glucose by amylase and maltase. sucrose and lactose are broken down by sucrase and lactase

Answer:

Decomposition is the process by which carbon atoms are released into the soil.

Explanation:

Organic decomposition involves the process of degradation of a living organism by releasing its elemental components.

In the process of decomposition, chemical elements such as carbon are released mainly in the soil, contributing to its enrichment and use by other living beings.

The release of carbon —product of decomposition— to the soil, for recycling, is part of the carbon cycle.

The other options are not correct because:

Answer:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Photosynthesis box:

Cellular Respiration box;

Photosynthesis is a process whereby green plants (producers) produce food in the form of glucose from inorganic materials such as water and carbon dioxide with the help of sunlight. The process takes place in the chloroplasts of green plants and oxygen is a by-product of the reaction.

Cellular respiration, on the other hand, involves the breakdown of foods in the form of glucose to release the energy stored in them for the use of cells. The glucose reacts with oxygen to produce energy in the form of ATP while carbon dioxide and water are produced as by-products. The process takes place in the mitochondrion and both producers and consumers require it in order to generate energy for metabolic processes.

Traces of the dead bodies present on the sedimentary rocks are fossils identification parts. By the physical appearance as well we can see the fossils and the types.

Molds and the casts are the ways by through the fossils are formed out.

Something becomes  fossil then it is  mineralized or later  becomes is  made of  the minerals. This is  usually meaning  an increase in  the weight. A fossil bone is  just heavier than the normal bone that is  noticeably so. So if object is heavy then  it  just might be the fossil. Sediment might fill mould and later  form cast fossil.

Have an eye that looks  for  the detail Look for the  regular lines along with the  marks or the  patterns on the  pebbles just like ridges or the  growth lines in the shell. Looking  for  the tiny pieces  that are among the beach pebbles and  not only the big stones. Often the crinoid stems or  the belemnites can also be small as the little fingernail.
