Toxoplasma gondii is a parasite that can infect cats and other animals. Humans can become infected by coming into contact with cat feces containing the parasite. Once inside a human host, toxoplasma can manipulate behavior and potentially lead to changes in personality and cognitive function. It is estimated that around one-third of the world's population has been exposed to toxoplasma at some point in their lives. **

Toxoplasma is a parasite that can be found in the feces of infected cats. When humans come into contact with the parasite, they can become infected. Toxoplasma has been found to manipulate the behavior of its hosts, including humans, by altering neurotransmitter levels in the brain. This manipulation may lead to changes in behavior and personality, although the extent of its effects on humans is still being studied. **

Toxoplasma parasites are single-celled organisms that can infect most warm-blooded animals, including humans. They primarily reproduce in cats and are spread through their feces. When humans become infected, the parasites can cause flu-like symptoms, muscle aches, and swollen lymph nodes. In people with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, toxoplasma infection can cause severe illness and even be life-threatening. Pregnant women who become infected can pass the parasite to their unborn child, which can lead to serious birth defects. Therefore, while toxoplasma parasites may not be dangerous for most healthy individuals, they can pose significant risks for certain vulnerable populations. **

A gas heater uses a spark to ignite the gas and create a flame. Once the gas is ignited, it continues to burn and produce heat without the need for a continuous spark. Therefore, after the initial spark, there is no need for it to remain lit as long as the gas is burning. This is why you may only see a spark when the gas heater is turned on, and not a continuous flame. **

To heat a plate over a candle flame, you can hold the plate above the flame at a safe distance to avoid direct contact with the flame. Move the plate back and forth over the flame to evenly distribute the heat. Be cautious not to hold the plate too close to the flame to prevent it from getting too hot or potentially breaking. **

No, ember is not hotter than fire. Ember is the glowing remains of a fire that has started to die down, whereas fire is the active, burning flames produced by a combustion reaction. Fire typically burns at a higher temperature than ember, as it is actively consuming fuel and releasing heat and light. **

An ember tetra is a small freshwater fish that is popular in the aquarium hobby. It is known for its vibrant red and orange coloration, resembling the glowing embers of a fire, hence its name. Ember tetras are peaceful and social fish that do well in community aquariums with other small, non-aggressive fish. They are relatively easy to care for and are a great choice for beginner fish keepers. **

Yes, a horse's blaze can change over time. A blaze is a white marking on a horse's face, and it can change in size, shape, or color as the horse grows and ages. Sometimes, a horse's blaze may become more pronounced or fade as the horse's coat changes with the seasons. Additionally, injuries or scars on the face can also alter the appearance of a horse's blaze. **
