In communities where zebra mussels have invaded we observed that the population of invertebrates, zooplankton, and phytoplankton they will decrease when in open water. The population of bottom-dwelling invertebrates which are in the littoral zone will increase.
Hypothesis shows the zebra mussels will affect the fish negatively that feed on plankton in the open water but affect positively the fish which feed on invertebrates which are in the littoral zones.
The predictions by following the invasion of zebra muscles show that the number and growth rate of fish species in open water will decrease in population whereas the number and growth rate of fish species in the littoral zone will increase in population.
Answer:
The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.
Explanation:
The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.
A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
Answer:
Cuando la levadura activa (viva) tiene tanto azúcar como oxígeno disponibles, "respira" mediante un proceso llamado respiración aeróbica. En esta reacción, las células de levadura utilizan glucosa (azúcar) y oxígeno (del aire) para producir energía. También producen agua y dióxido de carbono (un gas). Este es el mismo proceso químico utilizado por los humanos.
Explanation:
The answer is b because that's the only place where the leaf can be water to go through transpiration and the water cycle
