The correct sequence of these four events that occur during meiosis is:

  1. Chromosomes are replicated
  2. Spindles form and homologous pairs of chromosomes separate
  3. Centromeres divide and sister chromatids separate
  4. Gametes are produced

Explanation:

  1. Chromosomes are replicated (Event 4) during the S phase of interphase, before meiosis begins.
  2. Spindles form and homologous pairs of chromosomes separate (Event 2) during meiosis I, specifically in anaphase I.
  3. Centromeres divide and sister chromatids separate (Event 3) during meiosis II, specifically in anaphase II.
  4. Gametes are produced (Event 1) at the end of meiosis II, resulting in four haploid cells.

3. Explain why there are both upper and lower limits to cell size. As volume increases, what happens to the surface area: volume ratio? What other features of a cell can influence the surface area: volume ratio? 4. Describe the structure of the nucleus. What is its function? What is the envelope like? What do the pores do? How is the envelope and its pore structure related to the function of the nucleus? Notice that the nucleolus is a particular subpart of the nucleus. What happens there? 5.

Give a geometrical explanation as to why ∫ from a to a f(x) dx = 0 Choose the correct answer A. Any function f(x) integrated from a to a will be zero because exactly half of the function will lie to the right of the y-axis, and the other half left of the y-axis B. The length of the interval [a, a] is a-a=0 Therefore, the net area of the region bounded between f(x) and the x-axis, within the limits of integration, must also be zero C. Any function f(x) integrated from a to a will be zero because exactly half of the function will lie above the x-axis, and the other half below the x-axis D. The height of the function on the interval [a, a] is f(a)-f(a)=0. Therefore, the net area between f(x) and the x-axis, within the limits of integration, must also be zero.

Select all that apply Which of the following options correctly describe fatty acids? Select all that apply. Double bonds in naturally occurring fatty acids usually have an E configuration. Saturated fatty acids contain no C=C double bonds in their chains. The melting point of a fatty acid decreases as the number of double bonds in the carbon chain increases. Naturally occurring fatty acids have carbon chains with 6-12 carbon atoms. All fatty acids contain a COOH group.
