Visible light can cause skin damage, such as sunburn, premature aging, and an increased risk of skin cancer. Prolonged exposure to visible light can also lead to damage to the eyes, such as cataracts and macular degeneration. It is important to protect your skin and eyes from excessive exposure to visible light by wearing sunscreen and sunglasses.
What else can I help you with?
Are there visible nuclei in the sclerenchyma tissue?
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
Why can't clinical trials be done on human tissue samples only?
The tissue samples are not alive. They are not growing/moving like a living human so the effects the drugs have on the non living samples may be different to the effects on a living human.
What is the living tissue in teeth?
A living cell is the smallest structure of that carries out specific functions.
Is parenchyma a dead tissue?
No, parenchyma is living tissue found in plants. It fills the spaces between other cells and helps with functions like photosynthesis, storage, and support.
A beam of protons and a beam of neutrons of the same energy are both harmful to living tissue the beam of neutrons however is less harmful suggest why?
Neutrons are less harmful to living tissue compared to protons because neutrons rarely interact with biological material, whereas protons can cause ionization in tissues, leading to damage. Neutrons are neutral particles and have no charge, so they do not cause direct ionization and mainly interact through scattering effects in tissue.
What happens when you put eye drops when you're on LSD?
LSD is potent in such very small quantities that it can have significant effects when it comes in contact with skin, which is dead tissue. If it is capable of absorbing through dead tissue to living tissue in large enough quantities to have effects, then it is certain to have effects when put on living tissue, which has much closer contact to the bloodstream and therefore the brain. In short, it certainly will, even in very small quantities.
Why clinical trials can't be done on human tissues?
The tissue samples are not alive. They are not living or moving like a living human. The effects of the drugs may be different on 'non living' samples may be different to the effects on a non-living human.
Are there visible nuclei in the sclerenchyma tissue?
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
Why clinical trials can't be done on human tissue samples only?
Clinical trials require studying the effects of a treatment in a living organism to understand its overall impact, including potential side effects and interactions with other bodily systems. Human tissue samples lack the complexity of a functioning organism, meaning that critical information about how a treatment interacts with the body as a whole would be missed.
Why can't clinical trials be done on human tissue samples only?
The tissue samples are not alive. They are not growing/moving like a living human so the effects the drugs have on the non living samples may be different to the effects on a living human.
What kind of body tissue is both living and non living?
connective tissue proper
Are there visible nuclei in the tissue?
Yes, nuclei are typically visible in tissue samples when viewed under a microscope. Nuclei contain DNA and are stained with dyes to make them more visible for analysis. They appear as dark, round structures within the cell.
What type of bone tissue does not have any open visible spaces?
Compact bone tissue does not have visible open spaces. It is dense and made up of cylindrical units called osteons, which are arranged in layers. This type of bone tissue provides strength and support for the skeleton.
Is connective tissue living?
Yes, connective tissue is living tissue made up of cells and extracellular matrix. The cells in connective tissue help to maintain and repair the tissue, while the extracellular matrix provides structural support.
Are bones living tissue?
yes, they are an ossified tissue
Is tissue living?
Any tissue of a living organism containing cells that are being replaced when they die.
What are negative effects of visible light?
It could blind you, sunwise burn you or give you cancer
