D. more, faster
Explanation:
The more surface area exposed the faster the weathering occurs.
Answer: The idea that the earth is extremely ancient.
Explanation:
Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.
Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.
The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.
Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.
Answer: Aspergillus
Explanation:
Aspergillus is the fungal species which is highly aerobic in nature. It is found in the oxygen rich environment. This fungal species grows as molds typically over the substrate, as a result of high oxygen tension. The molds are toxic in nature. It grows over certain fruits, vegetables like apricots, peanuts, onions and grapes. It is the common contaminant of food. It is responsible for causing liver cirrhosis.
On the basis of the given situation this can be said that Steve is infected by Aspergillus.
Answer:
All plasmids we manufactured are free of animal-derived materials and can contain low levels of endotoxin (<100EU/mg, on request). This process is designed to meet our customers’ diverse downstream applications such as transfection, antibody preparation, vaccine, and gene-therapy research, etc.
