The average length of a specific dinosaur leg bone is 60 inches, with a standard variation of 3 inches. If a z-score is 0, then the length is 67.
Divide your data point by your standard error after taking your data point and subtracting the mean from it. How is the z-score determined? Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, & the population variation. The z-score is just the raw score less the population mean, split by the population variance, as the calculation demonstrates. You now have your Z-score. For instance, a scoring of 450 would equate a scores of (450-500)/100 (= -50/100 = -0.50 on a scale with a mean of 500 as well as a standard variation of 100, indicating that the scoring is half a variance below the mean.

Answer and Explanation:
Nondisjunction occurs when homologous chromosomes fail to segregate during anaphase I or sister chromatids fail to segregate during anaphase II. The result is an addition or loss of one or more chromosomes. Nondisjunction is associated with disorders like Down's syndrome due to an extra chromosome, Klinefelter's syndrome or Turner's syndrome. These phenomenon where one has three members of homologous chromosome is called trisomy.
Answer:
The correct order, from fastest to slowest, for the passage of molecules and ions through the cell membrane is oxygen, sodium ions, glucose (option D).
Explanation:
The plasma membrane is a lipid bilayer, with glycoproteins and membrane proteins, which constitutes a semi-permeable barrier to the passage of substances into and out of the cell.
The speed with which a substance can pass through the membrane depends on its chemical properties -hydrophilic substances pass through with greater difficulty than lipophilic ones- requiring in some cases specialized transport mechanisms. The different rates with which a substance passes depends on this.
- <em>Oxygen (O₂) </em><em>passes through simple diffusion, depending on a concentration gradient. It's the molecule that passes through the membrane the fastest.
</em>
- <em>In second place, there would be the </em><em>Na⁺ ions</em><em> -charged atoms- that cross the membrane by facilitated diffusion, through specific ionic channels.
</em>
- <em>The </em><em>glucose</em><em> molecule, being larger, requires the use of transport proteins, being its passage through the membrane slower with respect to oxygen or sodium.</em>
Undoubtedly, molecular weight and affinity for the plasma membrane are determining factors for the passage of molecules through the lipid bilayer.
