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.

<span>At least 50% of the variation in the trait in the population is due to genetic differences.</span>
That is true. Active transport goes against the concentration gradient. Particles want to move from higher concentration to lower concentration and even out, but active transport makes them move against that.
Conjugation
The process by which isogamous organisms exchange genetic information during fertilization is called conjugation.
In process of meiosis. The hypothalamus or the master gland in most animals, including humans send signals to the ovaries and testes of the reproductive system. In response to these signals, these ovaries and testes undergoes thesex cells division which is called meiosis<span>. </span>Spermatogenesis <span>in male gametes, is the process of sex cell division among sperm cells. On the other hand, </span>oogenesis<span> is for the female gametes. These cell divisions among respective gametes produces haploid cell which only contain one pair of chromosomes, in number -23.<span> </span></span>
About 90% of our DNA is the same.
