Water first-rate has significantly laid low with the presence of acid and base within the water. So answer is lake a: ph = 6.6; lake b: ph = 6.8.
The water isn't always precise for fitness whilst its exceptionally acidic or exceptionally basic. If the pH of water is almost impartial, this water is nice for consuming purpose. In the choice 3, each lake A and lake B has pH almost impartial so this water reasons no awful impact at the fitness of the human body. Highly acid water has low water first-rate because of the presence of metals which adversely have an effect on our body.
<h3>What is pH of lake water ?</h3>
The pH degree of the water in rivers, lakes, and wetlands is critical to plant and animal life is 7.

Explanation:
Muscles act on joints antagonistically. Some muscles will contract while other contract pulling on bones around joint hence enabling movement. An example is the elbow joint is moved by antagonistic action of biceps and triceps. When your biceps contract and triceps relax you are able to bend your arm at your elbow. When your triceps contract and biceps relax, your arms straighten.

Limited factors would mean that as the population in a community grows individual species would have to compete for those limited factors as the population reaches its carrying capacity. Also, the population as a whole would only be able to reach a certain number before falling due to there not being enough of the limited factors (ex. food) for that population to continue growing exponentially.
Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. this is an example of how the environment can influence on gene expression.
<span>
Light has an important role in gene expression in plants by producing a number of light-induced changes. One of the examples of the light effects is that chlorophyll and the proteins required for assembling the photosynthetic apparatus are synthesized together with the enzymes needed for carbon fixation. Gene expression influenced by light includes the regulation at the level of transcription or, alternatively regulation of translation.</span>
During meiosis, genetic recombination may occur more than once through the process of cell division, resulting in an increase in genetic variability.
