The answer to this is:
It is invalid because it could not stand up to experimentation
The human body is a complex and thriving ecosystem. It contains about 1013 human cells and also about 1014 bacterial, fungal, and protozoan cells, which represent thousands of microbial species. These microbes, called the normal flora, are usually limited to certain areas of the body, including the skin, mouth, large intestine, and vagina. In addition, humans are always infected with viruses, most of which rarely, if ever, become symptomatic. If it is normal for us to live in such close intimacy with a wide variety of microbes, how is it that some of them are capable of causing us illness or death?
Pathogens are usually distinct from the normal flora. Our normal microbial inhabitants only cause trouble if our immune systems are weakened or if they gain access to a normally sterile part of the body (for example, when a bowel perforation enables the gut flora to enter the peritoneal cavity of the abdomen, causing peritonitis). In contrast, dedicated pathogens do not require that the host be immunocompromised or injured. They have developed highly specialized mechanisms for crossing cellular and biochemical barriers and for eliciting specific responses from the host organism that contribute to the survival and multiplication of the pathogen.

Answer:
Research shows that changes in climate create warmer, drier conditions. Increased drought, and a longer fire season are boosting these increases in wildfire risk. ... Changes in climate add to these factors and are expected to continue to increase the area affected by wildfires in the United States.
<h2>Answer 1:</h2>
The gravitational force is a force that attracts any objects with mass. Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy including planets, stars, galaxies, and even light are brought toward one another.
Answer 2:
Gravity keeps things together. It is a force that attracts matter towards it. Anything with mass creates gravity, but the amount of gravity is proportional to the amount of mass.
Gravitational force is critical to our universe because with out gravitational force we cannot walk on earth, all the matter on earth cannot stay on it with out gravity. Everything will start floating in air with out gravity.
<h2>Answer 3:</h2>
Gravity is the powerful force that glues our universe together.
- One of the most noticeable effects of gravity in the solar system is the orbit of the planets.
- The planet keeps moving but is always caught up in the push-pull forces caused by the interaction of these gravitational forces. As a result, the planet begins orbiting the sun.
- The same phenomenon causes the moon to orbit around the Earth except its the Earth's gravitational force not the sun's that keeps it moving around us.
Chemokines act as chemoattractants. They lead <span>to the migration of immune cells to an infection site so they can target and destroy invading bodies such as microbes. Hope this helps.</span>
Most likely the first one is going to happen if there's a mutation.
