What is the role of the oral dentist?

Tooth extractions are carried out by dental and oral specialists for various reasons. A painful tooth or a tooth that has been significantly affected by decay may be the problem. Sometimes a dentist will extract a tooth to make room for dental prostheses or other devices.

When the situation becomes increasingly complicated, an oral expert rather than a dental professional may need to extract a tooth. They typically remove wisdom teeth or third molars.

The dental professional or specialist will initially numb the tooth to gradually relax the patient. Even though tooth extraction may still be distressing, it may be essential for relieving dental pain and preventing further problems.

A student, who is studying two different cells A and B in cell cycle, notices that cell A has 5 picograms of DNA while cell B has 10 picograms of DNA. Both cells are from the same organism. Which of the following is the best description of the cell cycle stage of each cell?
A. Cell A is in prophase of mitosis; Cell B is in metaphase of mitosis.
B. Cell A is in G1 phase; Cell B is in G2 phase.
C. Cell A is in G1 phase; Cell B is in between G1 and S phase.
D. Cell A is in G2 phase; Cell B is in G1 phase.

Answers

Answer:

As the cell enters meiosis 1, it's DNA replicates in S phase and then reduces to half when the cell splits into two. Hence, the amount of DNA remains 10 pg.

During meiosis 2, there is no DNA replication but only division between cells, leading to 5 pg of DNA in all four daughter cells.

So, the correct option is '10 pg and 5 pg respectively'

Describe an example of a sustainable yield model, other than a forest, that could help you make decisions about how to use your island resources.

Answers

Sustainability is the idea that people may live on Earth and utilise resources without destroying them or affecting future generations. The biological variety, food production, average global surface temperatures, CO2 concentrations, human population, and resource depletion are the five main environmental indicators that might point people in the direction of sustainability.

How can we figure out what yield is sustainable?

The foundation for determining sustainable yield is the ratio of the water level decline in the well to the pumping rate, the amount of drawdown the well exhibits for a particular pumping rate over time, and the recovery rate. Data from aquifer tests are typically more trustworthy the longer they are conducted.

Example is a fish that can be kept alive forever because they can be nourished by the underlying natural system's regenerating abilities.

Describe the hearing process​

Answers

So to put this in a question, I would rephrase it to:

How does hearing work?

It's a little tough to ELI5 without using using the names of the particular organs but here goes:

Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).

The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.

Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.

In essence, your ear works as follows:

Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.

Cheers,

ROR

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

The first step of the scientific method usually involves _______.
Multiple Choice

a. gathering data
b. developing a hypothesis
c. identifying relationships between variables
d. making observations

Answers

Answer:

b. developing a hypothesis

The first step of the scientific method usually involves making observations. Therefore option D is correct.

Observations are systematic and objective observations of the natural world. Scientists use their senses or specialized tools to collect data and gather information about a particular phenomenon or problem.

These observations serve as the foundation for scientific inquiry and help researchers identify patterns, trends, or potential relationships between variables.

From these initial observations, scientists can then move on to formulating a hypothesis (b), which is a testable explanation or prediction based on existing knowledge and observations.

The scientific method guides researchers in a structured approach to understanding the natural world and conducting experiments to test their ideas.

Therefore option D is correct.
