Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.
Why do bacteria only grow at certain temperatures?
- The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
- Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
- An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

Endomembrane system include: the nuclear membrane, the endoplasmic reticulum, theGolgi apparatus, lysosomes, vesicles,endosomes and the cell membrane.
Answer:
The correct answer would be - complex eyes evolved in the gradual steps, each of which was fully functional and adaptive in improving visual acuity.
Explanation:
The natural selection of the complex traits such as the vertebrate eye (complex eye) are seems to be problematic, many biologist think that the complex eyes evolution is take place in gradual steps and each step of this evolution was adaptive and functional in improving the visual acuity.
The steps that were involved are like light sensitivity patch, a deepening hole or pit that help in sharp vision and many other random evolution steps.
Thus, the correct answer is- complex eyes evolved in the gradual steps, each step of this evolution was fully functional and adaptive that helps in improving visual acuity.
True. The law of science says so so it is
