A) both have strong scientific support.
Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.
This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.
The human activities that could have endangered botana curus is:
Pollution: It lead to slow down the rate of growth of the plant.
Overexploitation: The over use of plant for its medicinal purpose.
Habitat: The natural habitat of the plant has been changed due to various human activities.
<span>previous changes in climate were dramatic but very short-lived.

<span>The issue of whether human activities cause global climate change is indeed a controversial topic. The limitation to climate research that could be overcome through scientific design is "Data from a wide range of time periods must be analyzed." Very powerful, or Super Computers, are required to analyze large amounts of data. The sooner more powerful computers are developed, the sooner data from the wide range of time periods can be analyzed. This will give scientists a better idea of the extent of global warming, if any, and how to prevent it.

<span>Skeletal muscle is a muscle tissue used when running a
marathon or blinking the eyes and formation of skeletal muscle comes from action
and myosin muscle fibers. Smooth muscle are found in the wall of internal
organs such as intestine and stomach. Contraction of the smooth muscle enable
the organs to performs their function while cardiac muscle is commonly found in
the wall of the heart. The contraction of the cardiac muscle enable the heart
to beats and pumps blood.</span>
