I think the best answer is D. It is thought that advances such as agriculture, literacy, and urbanization have not been accompanied by additional increases in brain size because the physiological cost of a bigger brain exceeds its benefit. The brain requires a lot of nutrients to function. Having a bigger brain would cost a lot rather than benefiting from it.
The answer is <span>c. mutualism.
</span>
<span>Mutualism is a relationship between two
different species in which both species have benefits. In this example, ants benefit because they feed on aphids' wastes while aphids benefit because ants provide them protection.
</span>
<span>Commensalism is a relationship between two
species in which only one of them has benefit, and the other one is not
affected. Parasitism is a relationship between two species in which only
one of them has benefit, and the other one is harmed.</span><span>

Answer:
The best evidence for the three domain system is
Sensitivity to Antibiotics
Explanation:
The three domains of life includes :
Archaea - oldest known domain, ancient forms of bacteria.
Bacteria - all other bacteria that are not included in the Archaea domain.
Eukarya - all the organisms that are eukaryotic or contain membrane-bound organelles and nuclei.
Types of evidences for the three domain system are:
1) differences in the sequences of nucleotides in the cell's robosomal RNAs (rRNA)
2) the cells's membrane lipid structure.
3) its sensitivity to antibiotics.
Answer:
Facultative anaerobe.
Explanation:
Bacteria can be classified on the basis of their nutrition requirement and on the basis of different condition of oxygen in which they live. Two main types of bacteria are aerobic bacteria and anaerobic bacteria.
Anaerobic bacteria grows in the absence of oxygen. The facultative anaerobe bacteria can undergoes the process of respiration in presence as well as in absence of oxygen. Thioglycollate chemicals helps to known the aero tolerance of the organism. The turbidity on the whole tube indicates that the bacteria is facultative anaerobe.
Thus, the correct answer is facultative anaerobe.
The answer would be B this is because herbivore means plants only so the answer is definitely B
