Answer:
The correct answer would be - mycobacterium, and streptomyces.
Explanation:
Actinobacteria is a phylum that consists of a group of gram-positive bacteria with cytosine and guanine content in their DNA. These bacteria can be aquatic or land bacteria. Actinobacteria do not have cell wall however they make a non-sptate and mycelium.
Mycobacterium is one of the genera of the actinobacterium phylum. This genus includes pathogenic species in it that cause deadly diseases in humans and other mammals such as leprosy and tuberculosis Whereas streptomyces is another genus of the actinobacteria that is yielded the very first drug to fight with the ancient scourge.
Thus, the correct answer is - mycobacterium and streptomyces.
This is due to the fact that women usually become infected at younger age than men. Many young women have a sexual relationship with older men who are more likely a hiv-positive, with the result that far more young women that young men in Africa were infected. Also the women are at higher risk of infection. The reason is both physical and socio-cultural.
The right answer is c. 3 to 10 million
The latest estimates are a bit more precise: there are 8.7 million living species (which is included in the range between 3 and 10 million), 6.5 million on land and 2.2 million in the water. Which is amazing, since there is more sea than land on our planet.
Researchers estimate that there are 7.77 million animal species, only 298,000 plant species and 611,000 species of fungi and molds.
