Answer:
DNA content is halved in both meioses I and meiosis II. Ploidy level changes from diploid to haploid only in meiosis II.
Explanation:
In meiosis, one diploid cell produces four haploid cells. At the end of meiosis I, just like in mitosis, we will have two diploid daughter cells and then these two cells undergo cellular division again. In this secondary division, more precisely in the anaphase II, the centromere divides <u>(this process does not happen in the meiosis I anaphase I, where homologous chromosomes move together to opposite poles)</u> and sister chromatids move to opposite poles, leaving four individual cromatids following a cytoplasmatic division forming four new haploid cells.
Osmosis is a passive transport which moves water molecules from higher to lower gradient.
<span>Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.<span>
</span></span><span>The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.<span>

Answer:
Egg graders determine quality based on the egg's: shell, white, yolk, and air cell. Here's how to tell a high quality egg from a low one.
Explanation:

The 99% Confidence Interval is:
</span><span>x¯</span>−<span>z<span>(1−c)/2</span></span>×<span>σ/√n</span>≤<span>x¯</span>≤<span>x¯</span>+<span>z<span>(1−c)/2</span></span>×<span>σ/<span>√n
</span></span>3.2−2.576<span>18.6/√48</span>≤3.2≤3.2+2.57618.6/√48
−3.72≤3.2≤<span>10.12
</span>Since 0 is included in this interval, these results suggest that a difference of 3.2 could have resulted from mere random variation.

</span>
<span> Note that we divided (1-.99) by 2 because we are interested in the two-tailed confidence interval.
We can validate our results using the confidence interval for mean calculator</span>
