Why is diffusion insufficient meet the oxygen requirements of multicellular organisms like humans?
In single-celled organisms the entire surface of the organisms is in contact with the environments for the diffusion of substances. In multi-cellular organisms all the cells may not be in direct contact with the surrounding environment. So simple diffusion will not meet the requirements of all the cells.
What supplies the articular cartilage of long bones with oxygen and nutrients?
The articular cartilage of long bones receives oxygen and nutrients from the synovial fluid that surrounds it within the joint cavity. This fluid is rich in nutrients and provides nourishment to the cartilage through diffusion. Additionally, the movement and compression of the joint during physical activity helps to facilitate this process.
What are some of the harmful effects for methemphetamine?
Some harmful effects of methamphetamine use include increased heart rate and blood pressure, intense euphoria followed by a crash, anxiety, paranoia, and insomnia. Long-term use can lead to addiction, cognitive impairments, dental issues ("meth mouth"), and increased risk of mental health disorders.
What is diffusion is it liquid?
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. It occurs in liquids, gases, and solids, as long as there is a concentration gradient present.
How does carbon oxcide level affect oxygen production?
Carbon dioxide levels affect oxygen production indirectly by influencing the rate of photosynthesis in plants. Higher carbon dioxide levels can stimulate photosynthesis, leading to increased oxygen production as a byproduct. However, if carbon dioxide levels get too high, it can also disrupt the balance of ecosystems, potentially affecting oxygen production in the long term.
How does long term exercise affect oxygen diffusion rates?
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
Why is a worm long?
One of the reasons worms are long are because of their general biological makeup. They have a very simple design lacking in lungs. They acquire their needed oxygen by diffusion through their skin. In order for a worm to acquire more oxygen a greater surface area is needed. This increased surface area can be accomplished by the worm being long and thin, but not by the worm being short and fat. it's an equation of surface area to volume. In being long and thin the oxygen can easily and rapidly diffuse across the worms membranes.
What are the potential side effects of a spleenectomy procedure?
Potential side effects of a spleenectomy procedure include increased risk of infections, particularly from encapsulated bacteria, as well as an increased risk of blood clot formation and potential long-term effects on the immune system.
What are the effects of being in the sun too long?
Sunburn, sun poisoning, and increased risk of skin cancer.
Is diffusion of materials over long distance fast?
diffusion of materials over long distance is fast

What are the shot term affect tabcco has on people?
Tobacco has a variety of short-term effects on the user both physical and psychological. Physically tobacco can cause increased heart rate and blood pressure increased risk of stroke and heart attack increased risk of developing respiratory illnesses and decreased oxygen levels in the blood. Psychologically tobacco can cause euphoria relaxation and increased alertness. It can also increase the risk of dependence and addiction as well as increase the risk of developing mental health issues such as depression anxiety and schizophrenia.The following are some of the short-term effects of tobacco use: Increased heart rate and blood pressure Increased risk of stroke and heart attack Increased risk of developing respiratory illnesses Decreased oxygen levels in the blood Euphoria relaxation and increased alertness Increased risk of dependence and addiction Increased risk of developing mental health issues such as depression anxiety and schizophreniaThese short-term effects of tobacco use can have serious and long-term health consequences and it is important to be aware of them when considering using tobacco.
What are some long term effects of overpopulation?
Some long-term effects of overpopulation can include increased strain on resources like food and water, degradation of the environment through pollution and deforestation, and increased competition for jobs and living space. Overpopulation can also lead to social issues such as overcrowding, poverty, and conflict.
How does alcohol affect the body long term?
Long-term effects of drinking alcohol in moderation are the significantly increased chances of better health and longer life.
How does nitrogen gets in the air?
nitrogen molecules move into the air by diffusion of h2o2 coming from animals.
What are the short and long term effects of eating healthy?
Increased energy and metabolism, greater efficiency at processing foods, and better body composition
What affects are there with having insomnia?
