Answer:
Because most natural environments harbor a stunningly diverse collection of microbial species. Within these communities, bacteria compete with their neighbors for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microbes. Additionally, a growing body of theoretical and experimental population studies indicate that the interactions within and between bacterial species can profoundly impact the outcome of competition in nature. The next challenge is to integrate the findings of these laboratory and theoretical studies, and to evaluate the predictions they generate in more natural settings.
Explanation:
Answer:
The correct answer is - False.
Explanation:
Water vapor is water in its gaseous state. Water vapor is totally invisible, an individual can not see water vapor in any situation with naked eyes. Fog, clouds, mist are not the water vapor as they contain liquid water or droplets.
Water vapor is essential for the weather and climate, without water vapor there would be no rain, snow or clouds as require water vapor to form.
Thus, the correct answer is - false.
Answer:
The cell membrane is semi-permeable. It allows some molecules to enter easily inside the cell whereas some molecules are blocked from entering the cell.
Small, polar molecules and hydrophobic molecules enter easily through the cell membrane. But large molecules and ions cannot easily move inside the cell membrane.
A hydrophilic substance like the substance L mentioned in the question enters the cell membrane through the help of carrier proteins. The substance attached to the large protein might enter through active or passive diffusion but it can only enter the cell by attaching to carrier proteins.
All genetic information is found in the DNA
