What was the effect of ether on elicciting an action potential?
Ether causes potassium ion pores to open, allowing potassium ions to leave the neuron, hyper-polarizing the neuron so it is unable to fire an action potential.
What is bacterial inactivation?
Bacterial inactivation refers to the process of killing or rendering bacteria unable to grow or reproduce. This can be achieved through various methods such as heat treatment, chemical disinfection, or exposure to radiation. Bacterial inactivation is important in food preservation, water treatment, and medical settings to prevent the spread of infectious diseases.
Is UV-b a form of ionizing radiation?
No, UV-B is not considered ionizing radiation. Ionizing radiation has enough energy to remove tightly bound electrons from atoms, creating charged particles (ions), while UV-B radiation has lower energy levels that are unable to cause ionization in atoms. UV-B radiation can still have harmful effects on living organisms, such as skin damage and increased risk of skin cancer, but it does not have the same ionization capabilities as ionizing radiation.
Why table salt is called iodized salt?
Table salt is iodized (that is, iodine is included via sodium iodide or potassium iodide) because people used to be unable to get enough iodine from their diets, and iodine is necessary for a person's thyroid gland to work properly. Since the thyroid is responsible for growth and immunity, people with thyroid deficiency had dramatic problems including dwarfism and goiter (a lump on the front of the throat where the thyroid gland resides). As a result of these problems, iodine was added to table salt (NaCl). These days, it is actually more likely that a person will develop iodine toxicity (i.e. overdose on iodine) because a typical person's salt intake is SO high above what we need for sodium or iodine. One sign of iodine toxicity is greasy skin and pimples.
What problems do cells have when there are too many potassium ions inside?
When there are too many potassium ions inside the cell, it can disrupt the cell's ability to maintain its resting membrane potential. This can lead to alterations in cell signaling, muscle contractions, and nerve function. In severe cases, it can even cause cell damage or death.
Which of the following cell types are least sensitive to ionizing radiation damage?
Red blood cells are the least sensitive to ionizing radiation damage because they lack a nucleus and are unable to repair DNA damage caused by radiation exposure. This also makes them unable to undergo cell division or replication.
Why is the axoloti such an unusual salamander?
These salamanders lack iodide in their system and therefor unable to grow lungs
Why potassium iodide can conduct electricity in the molten state but not in solid state?
Potassium Bromide or KBr is not able to conduct electricity in solid state. It is an ionic compound and its ions are not free to move in the solid state, hence they are not able to conduct electricity. But when they are in aqueous state, they are free to move and thus become able to conduct electricity.
Who discovered lead iodide crystals?
I was unable to discover any citation about PbI2 before 1885 (Lehmann); but probably the first preparation is older.
Why would the earth be barren without the atmosphere?
The atmosphere plays a crucial role in supporting life on Earth by providing oxygen for respiration, trapping heat to maintain a stable climate, and shielding us from harmful solar radiation. Without the atmosphere, Earth would be unable to sustain life as we know it, leading to extreme temperature fluctuations and increased exposure to radiation.
What element has the configuration of 1s22s22p63s23p64s1?
I count 19 electrons. That is potassium. You need to learn how to read a periodic table.
What condition is xeroderma pigmentosum?
Xeroderma pigmentosum is a very rare skin condition. Afflicted persons are unable to process ultraviolet radiation and so suffer severe sunburns at the slightest exposure to sunlight. Patients are required to avoid all contact with sunlight if they wish to live a normal, comfortable existence.
What was the effect of ether on elicciting an action potential?
Ether causes potassium ion pores to open, allowing potassium ions to leave the neuron, hyper-polarizing the neuron so it is unable to fire an action potential.
Is radiation the only form of heat transfer that is unable to travel through the vacuum of space?
No. You got it exactly backwards.
What is bacterial inactivation?
Bacterial inactivation refers to the process of killing or rendering bacteria unable to grow or reproduce. This can be achieved through various methods such as heat treatment, chemical disinfection, or exposure to radiation. Bacterial inactivation is important in food preservation, water treatment, and medical settings to prevent the spread of infectious diseases.
What is the Geiger counter's trigger called?
The trigger on a Geiger counter is typically called the "dead time." It is the period during which the counter is unable to record additional radiation events because it is processing a previous one.
Why bromine does not react with aqueous potassium chloride?
Bromine does not react with aqueous potassium chloride because it is less reactive than chlorine. Chlorine is more electronegative than bromine and hence has a higher tendency to displace bromine from its compounds. Consequently, bromine remains unreactive in the presence of aqueous potassium chloride.
