Answer: It's showing the change of the average temperature.
Explanation:
Answer:
Purple, spherical-shaped organisms arranged in chain like formations.
Explanation:
Bacteria are the microscopic organisms and included in the prokaryotes as they do not have nucleus. Two main types of bacteria are gram positive bacteria and gram negative bacteria.
The gram positive bacteria has thick cell wall peptidoglycan cell layer and can uptake the crystal voilet stain. These bacteria seems purple under the microscope due to the uptake of stain. The bacteria Streptococcus pyogenes are spherical in shape and occurs in the cluster of chain.
Thus, the correct answer is option (d).
Oxygen concentration is the primary factor that controls NOx during the devolatilization process, and reducing conditions during devolatilization favor the formation of N2 instead of NOx. The residual char left after the initial devolatilization steps burns more slowly than the volatiles, and the corresponding slow rate of char nitrogen conversion to NO is difficult to control
Biological evolution is the process through which the characteristic of organisms change over successive generations, by means of genetic variation and natural selection. It is most commonly defined as "changes in gene frequencies in populations".
