What are T-helper cells and T-killer cells?
T-helper cells, also known as CD4+ cells, are a type of white blood cell that play a crucial role in the immune system by coordinating the immune response. They help activate and direct other immune cells, such as B cells and T-killer cells, to fight off infections. T-killer cells, also known as cytotoxic T cells, are another type of white blood cell that are responsible for directly killing infected cells or cancer cells in the body. Together, T-helper cells and T-killer cells work in harmony to mount an effective immune response against pathogens. **
Do T-killer cells arise from T-lymphocytes due to the activation of T-helper cells?
No, T-killer cells do not arise from T-lymphocytes due to the activation of T-helper cells. T-killer cells, also known as cytotoxic T cells, are a subset of T-lymphocytes that are activated by the recognition of specific antigens presented by antigen-presenting cells. Once activated, T-killer cells can directly kill infected or abnormal cells. T-helper cells, on the other hand, play a different role in the immune response by helping to activate other immune cells, including T-killer cells, through the release of cytokines. **

What happens when T-helper cells are no longer present?
When T-helper cells are no longer present, the immune system's ability to coordinate an effective response to pathogens is compromised. This can lead to a weakened immune response, making the body more susceptible to infections and diseases. Without T-helper cells, other immune cells may not be properly activated, resulting in an inability to mount an appropriate immune response. This can have serious consequences for overall health and can lead to increased vulnerability to various illnesses. **

How does HIV virus cause damage to T-helper cells?
The HIV virus enters T-helper cells by binding to the CD4 receptor on the cell surface. Once inside the cell, the virus replicates and produces new viral particles, which can then infect other T-helper cells. This continuous cycle of infection and replication leads to a decline in the number of T-helper cells, weakening the immune system and making the body more susceptible to infections and diseases. Additionally, HIV can also directly cause cell death in T-helper cells, further contributing to the damage to the immune system. **

How big are cells?
Cells can vary in size depending on the type of organism and the specific function of the cell. Generally, most cells are microscopic, ranging in size from 1 to 100 micrometers. However, there are exceptions, such as the egg cell of an ostrich, which can be visible to the naked eye and is one of the largest cells in the animal kingdom. Overall, cells come in a wide range of sizes, but the majority are too small to be seen without the aid of a microscope. **

Why are liver cells animal cells?
Liver cells are animal cells because they are part of the tissue and organ system of animals. They are eukaryotic cells, meaning they have a true nucleus and membrane-bound organelles, which are characteristic of animal cells. Additionally, liver cells perform specific functions related to the metabolism and detoxification of substances within the body, which are essential for the survival and functioning of animals. Therefore, liver cells are classified as animal cells due to their structure, function, and role within the animal body. **
What are the differences between embryonic stem cells, omnipotent stem cells, adult stem cells, totipotent stem cells, and multipotent stem cells?
Embryonic stem cells are derived from embryos and have the potential to develop into any type of cell in the body. Omnipotent stem cells, also known as pluripotent stem cells, are similar to embryonic stem cells in that they can differentiate into any type of cell, but they are derived from adult tissues. Adult stem cells are found in various tissues and have the ability to differentiate into a limited range of cell types. Totipotent stem cells have the highest potential for differentiation and can develop into any type of cell, as well as into extraembryonic tissues such as the placenta. Multipotent stem cells can differentiate into a limited number of cell types, typically within a specific tissue or organ. **
How does cloud cover affect the performance of solar cells?
Cloud cover reduces the amount of sunlight reaching solar cells, which in turn reduces their performance. Solar cells rely on sunlight to generate electricity, so when there is less sunlight due to cloud cover, the output of the solar cells decreases. This means that solar panels produce less electricity when there is cloud cover, which can impact their overall efficiency and effectiveness in generating power. However, advancements in solar cell technology have made them more efficient at capturing and converting sunlight, even in partially cloudy conditions. **
