<span>The disinfectant that was the most effective at controlling the growth of E. coli is disinfectant 2 because of the least number of Ecoli strains found on the dish compared to the other disinfectants. Also dish 4 that cointains water has the most number of Ecoli strains because water is not a disinfectant and Acoi do not die in water alone.</span>

Answer:
The Laura tried to grow micro-organisms in culture broth medium in Petri-plates but the microbial growth was not observed even on the fourth day of culture which could be due to:
1. Laura could have not provided the correct broth medium maintaining the with pH and salt concentrations.
2. Microorganisms did not get optimal growth conditions.
3. The bacterial source could have died after the collection which could have lysed after their death and thus no longer visible.
The little dots collected from under the fern leaves are spores, not seeds. Ferns are different from seed-bearing plants in that ferns in a sexless way through sporophyte generation. Spores dropped from or taken from grown fern leaves have developed prothallium. Each prothallium generates male and female organs in what is called the gametophyte stage. When fertilization of the female gametophyte happens, small fern plants or leaflets start to grow.
Answer:
The correct answer is: A) Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
Explanation:
Photosynthesis is the process by which green plants, which include algae, take in the energy from the sun and combines it with carbon dioxide (and water) to form benificial sugars.
Photosynthesis refers to the process by which the green plants, as well as algae, utilize the energy from the sun in combination with the carbon dioxide as well as water to form simple sugars. This is how the harmful gas carbion dioxide can be destroyed and elimanated.
