"The centre of the earth is harder to study than the centre of the sun." Temperatures in the lower mantle the reach around 3,000-3,500 degrees Celsius and the barometer reads about 125 gigapascals, about one and a quarter million times atmospheric pressure."

Tetrapods are the most recent common ancestor with the lungfish look like.
Ancient species of lung fish are the ancestors of tetrapods. These fish may live on land, breathing air and being propelled by their pelvic fins. Australia has three populations of the few remaining lungfish — two marine populations and one inhabiting the Mary River basin in Queensland.

Explanation:
<em>Clostridium tetani</em> bacterium would be most likely to produce a molecule tetanospasmin toxin that could be modified to create a drug for treatment of muscle spasms (uncontrolled contractions)
An infection known as tetanus is brought on by the <em>Clostridium tetani</em> bacteria. When bacteria enter the body, they release a toxin that makes muscles contract painfully.
Tetanus is frequently referred to as "lockjaw" since one of its most noticeable symptoms is a tightening of the jaw muscles. Tetanus infection can cause major health issues, such as difficulty opening one's mouth, swallowing difficulty, and breathing difficulties.
Tetanus does not transmit from individual to individual, making it distinct from other infections that can be prevented by vaccination.

Answer: Grassland is the biome which is characterized by it's lack of trees, warm temperatures, and it's moderate rainfall.
Grasslands are generally open and continuous, flat areas of grass. They are often found between temperate forests at high latitudes and deserts at subtropic region. Grasslands lack trees, due to poor infilteration of soil, too deep water table or water table is too high, very thin layer of soil over hard rock, soil is acidic in nature, poor in macronutrients and low presence of organic matter. The climate in grasslands varies, but natural grasslands are generally hot and dry. The amount of rainfall received by grasslands depends about the level where they are situated. The amount of rainfall received by grasslands is lower then tropical forests and higher than deserts. Therefore, grasslands receives moderate rainfall.
