He used the compound microscope!
Answer is A. Archaebacteria
Archaebacteria are a type of single-cell organism. They are a group of most primitive prokaryotes which are believed to have evolved immediately after the evolution of the first life. Thermoacidophiles are the archaebacteria which can tolerate high temperature as well as high acidity. They often live in hot sulfur springs where the temperature may be as high as 80°C and pH as low as 2. Examples are Thermoplasma, Thermoproteus.
Answer:
The carrying capacity of the deer population on the Walla Walla island is about 80
Explanation:
Carrying capacity is the measure of the number of the deer present in an area which can further support them both biologically and culturally because of which the value gets changed annually, seasonally and across other properties. Because of these some hunters are able to see the deer on the other hand on a mile or so away can see few or none. Perhaps the hunting has reduced the deer population below its carrying capacity i.e. 30,000.
In the two maps that show the allele frequency of sickled hemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The color coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.
Hence the answer is A)When an area is malaria free, the HbS allele frequency is between 0 and 2.02.
