Answer:

It's Oxygen.

Explanation:

Some abiotic factors, such as oxygen, are important in aquatic ecosystems as well as terrestrial environments. Terrestrial animals obtain oxygen from the air they breathe. Oxygen availability can be an issue for organisms living at very high elevations, however, where there are fewer molecules of oxygen in the air.

Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.

Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).

Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.

Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.

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.

Surface water (rivers and lakes) are the most available source of fresh water. The other sources of fresh water are largely unavailable.

Water on earth could be fresh water or salt water. The difference between the two is that freshwater is not salty. There is a limited quantity of available freshwater on earth.

Fresh water is found in glaciers, surface lakes and rivers and groundwater.The order of decreasing availability of fresh water on earth is ice> Groundwater > lakes and rivers (surface water).

Unfortunately, the source of freshwater that can easily be obtained for human use is surface water (lakes and rivers). There is only about [tex]1\frac{2}{3}[/tex]% available freshwater in rivers and lakes. About 87% of the world's fresh water supply is locked away in glaciers.

Given the limited availability of fresh water sources, the possibility of an water challenges in the world can not be over emphasized. Definitely, there may not be enough water in the future hence water conservation efforts must be taken seriously.

In what ways can the use of statistics help in improving mental health services? Could the use of statistics cause potential misunderstandings of mental health services? How can you avoid any such misunderstandings?

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.

Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

Color of seeds Mendel chose to cross

Explanation:

This variable does not depend on the other variables you are trying to measure, so it is independent.

In Gregor Mendel cross, the variable does not depend on the other variables you are trying to measure, so it is independent.

Mendelian Crosses: In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation).

Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.

A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.

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.
