Cancer cells are cells that basically bypass any sort of regulatory processes in the cell cycle (and mitosis - the splitting of the cell). This leads to uncontrollable cell growth/duplication which hence leads to more and more cancerous cells. Cancer itself is so hard to cure for a couple of different reasons. If the cells are in the form of a benign tumor, that is a tumor that does not spread from its original infected tissue, it should be "easy" to remove with surgery. However, if it metastasizes, or spreads into surrounding tissues through the lymph or blood systems, then it becomes even harder to remove because of its far reach and complex structure. Also, cancer cells can be simply described as normal body cells that have gone rogue. That being said, things such as antibiotics, that are designed to get rid of foreign bodies, cannot get rid of cancerous cells without getting rid of most of your regular body cells as well simply because they cannot tell the difference.

Hope this helps :)

Sergio [31]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.

  • <u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
  • An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

When looking at groups of cells, which is ordered from smallest to largest?
Sedbober [7]
The smallest item in the list would be organelles. Organelles are tiny structures within a cell, that help it to function. Example of organelles are-- nucleus, mitochondria, cell membrane to name a few. Cells are the basic unit of structure and function of all living things, therefore, cells would have to be placed second. They are microscopic. A group of similar cells that work together to perform a specific function, is known as a tissue. Therefore, tissue is next largest. Examples of tissues include, muscle tissue, epithelial tissue, adipose tissue. When different types of tissues work together to perform a function in the body, this group of tissues forms an organ. An example of an organ is the heart. Inside the heart are many types of tissue-- cardiac muscle,nerve, blood, connective, etc. The job it performs is to pump blood. When various organs work together to perform a specific function in the body, this makes up a system. An example is the circulatory system. In this system are many organs that work together. Arteries, veins, capillaries and heart are all part of the circulatory system. Its job is to circulate blood containing nutrients and oxygen to cells and to pick up cellular wastes. All the systems of the body comprise the organism. An organism is a living thing. It can be as tiny as a microbe, or a complex as a human. When referring to a multicellular organism, the correct order from smallest to largest is-- organelle, cell, tissue, organ, system, organism

In the experiment described in the scenario, which group represents the control group?
kow [346]

Answer: D.) Plant D

Explanation: A control group is composed of the test subject(s) that do not receive any experimental treatment. In this case, Plant D is the control group because it does not listen to any music unlike the rest of the plants.
