Myths, misunderstandings, and negative stereotypes and attitudes surround mental illness. These result in stigma, discrimination,and isolation of people with mental illness, as well as their families and carers.
----------------------------------------------------------------------------------------------------------------
Are mental illnesses a form of intellectual disability or brain damage?
No. They are illnesses just like any other, such as heart disease, diabetes, and asthma. Yet the traditions of sympathy, support, and flowers given to people with physical illnesses are often denied to those with a mental illness.
Are mental illnesses incurable and lifelong?
No. When treated appropriately and early, many people recover fully and have no further episodes of illness.
For others, mental illness may recur throughout their lives and require ongoing treatment. This is the same as many physical illnesses, such as diabetes and heart disease. Like these other long-term health conditions, mental illness can be managed so that individuals live life to the fullest.
Although some people become disabled as a result of ongoing mental illness, many who experience even very major episodes of illness live full and productive lives.
Are people born with a mental illness?
No. A vulnerability to some mental illnesses, such as bipolar mood disorder,can run in families. But other people develop mental illness with no family history.
Many factors contribute to the onset of a mental illness. These include stress, bereavement, relationship breakdown, physical and sexual abuse, unemployment,social isolation, and major physical illness or disability. Our understanding of the causes of mental illness is growing.
Can anyone develop a mental illness?
Yes. In fact, as many as one in five Australians may develop a mental illness at some stage in their lives. Everyone is vulnerable to mental health problems.
Many people feel more comfortable with the notion of having 'a nervous breakdown' rather than a mental illness. However, it is important to talk openly about mental illness, as this reduces the stigma and helps people to seek early treatment.
Are people with mental illness usually dangerous?
No. This false perception underlies some of the most damaging stereotypes. People with a mental illness are seldom dangerous. Even people with the most severe mental illness are rarely dangerous when receiving appropriate treatment and support.
Should people with a mental illness be isolated from the community?
No. Most people with a mental illness recover quickly and do not even need hospital care. Others have short admissions to hospital for treatment. Improvements in treatment over recent decades mean that most people live in their communities, and there is no need for the confinement and isolation that was commonly used in the past.
A very small number of people with mental illness need hospital care,sometimes against their will. Improvements in treatment are making this less and less common, and fewer than one in a 1000 people are treated this way.
Which of the following is the observed result of aquatic species exposed to a toxin?
I. Developmental dysfunction
II. Gender imbalances
III. Increased reproduction rates
I, II, and III
I and II
II and III

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have a negative effect on aquatic species. The negative effects include:
Developmental dysfunctionGender imbalancesToxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.
The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female aquatic species such as reef fish.
Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

Answer:
i think that the higher the body temperature the higher the cellular respiration
Explanation:
The graph indicates the relationship between body temperature and cellular respiration. As the body temperature increases, more ATP is produced, but after a certain temperature, there is no cellular respiration.
What is cellular respiration?In cellular respiration, the cell breaks down glucose and forms ATP. Glucose is broken down by glycolysis, the Krebs cycle, the electron transport chain, and finally ATP is formed.
In the graph, it is shown that an increase in body temperature is related to an increase in ATP molecule production. ATP molecule production is nearly zero at 80 degrees body temperature. As the temperature increases to 100 degrees, ATP production increases to nearly 50.
After 100 degrees, the body temperature rises, but there is a decrease in ATP production. After 100 degrees, the enzymes required for cellular respiration don't work. Hence, a decline in ATP is seen.
Hence, after a certain temperature, the enzymes involved in cellular respiration don't function as their structure changes.

What two molecules are produced during Photosynthesis?
Answer:
outputs Glucose, oxygen
Explanation:
Explanation:
photosynthesis requires sunlight, carbon dioxide and water as starting reactants (figure 5.5). After the process is complete, photosynthesis releases oxygen and produce carbohydrate molecule, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
During the process of photosynthesis, cell use carbon dioxide and energy from the sun to make sugar molecules and oxygen.
Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?
Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.
Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.
The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.
However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.

How are the shapes of red blood cells and the shapes of nerve cells related to their functions? Thank you!
Answer:
How is the shape and size of red blood cells related to their function?
This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. Many RBCs are wider than capillaries, but their shape provides the needed flexibility to squeeze through.
Explanation:
Enzyme activity generally increases as temperature increases within an enzyme’s optimal range because an increase in temperature causes an increase in molecular motion. This increase in molecular motion results in the enzyme and its substrate coming into contact with each other more often. At too high a temperature, however, the enzyme will become denatured and no longer be able to function. As the video describes, that is what happens when someone has a high fever.
What do you think happens to enzyme activity as temperature decreases outside an enzyme’s optimal range? Explain your answer in terms of molecular motion.
This most reliable temperature is commonly around human frame temperature (37.5 °C) for the enzymes in human cells. Above this temperature, the enzyme shape begins to interrupt down denature given that at better temperatures intra- and intermolecular bonds are broken because of the enzyme molecules' advantage of even greater kinetic electricity.
Each enzyme has a temperature variety in which a maximal charge of response is accomplished. This maximum is referred to as the temperature most desirable of the enzyme. The most excellent temperature for maximum enzymes is set at ninety-eight. 6 tiers Fahrenheit (37 ranges Celsius). There also are enzymes that work nicely at decreased and better temperatures.
Most activity is accomplished on the enzyme's ultimate temperature. The lively website online of the enzyme modifications shape as the temperature rises above the surest temperature, resulting in a decline in interest. Above and under the highest quality temperature, activity decreases.
Most enzyme functions are done at 37∘C in humans due to the fact the enzymes are capable of holding their structure at that temperature, allowing it to break down complex molecules efficiently.

HELP PLEASE!!!explain how Earth is heated through conduction
As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.
It must be known that conduction happens mostly near the earth's surface.
Answer:
Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

Marine biologists have determined that when a shark detects the presence of blood in the water, it will swim in the direction in which the concentration of the blood increases most rapidly. Based on tests conducted by the biologists, the concentration of blood (in parts per million) at a point P(x,y,z) on the surface of sea water is approximated by
Blood concentration is approximated by the distance from the source.
The concentration of blood at a point P(x,y,z) on the surface of sea water is approximated by the distance from the source where the blood moves. Point x is the place where the concentration of the blood is the highest because at this point the source of blood present.
At point y, the concentration of the blood is lower as compared to point x but higher than point z, while on the other hand, at point z the concentration of blood is the lowest due to its presence farther from the source so we can conclude that blood concentration is approximated by the distance from the source.

In order for an organism to decompose to the point that only dry bones will remain, it is estimated that in warm and humid environments the process will take roughly three weeks, In which case the options of Days 26-43 as well as after day 50 are correct.
Decomposition is what happens to any dead organic material. Decomposition is when the organic material is broken down into smaller compounds, organic or not. This process is affected by a variety of conditions including:
TemperatureHumidityPresence and species of insectsElements to which the material is exposedand so on. Each of these factors can greatly impact how fast something will decompose.
The question at hand gives us the conditions for the fastest decomposition, given that this process is accelerated in warm and humid conditions. When in these conditions, it is estimated that an organism can take a minimum of three weeks to reach the stage in which all that is left is the skeleton (dry bones).
Three weeks consists of 21 days, however, option 6 that states "Days 18-25" is not being included given that during days 18-21, elements other than bones may still be present. For this reason, the correct answer is any day after day 21, that is, days 22-50+. Therefore, options 5 and 3 can both be considered correct as in those days only dry bones will remain.
