Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

  • homologs pair off into bivalents
  • At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I  forming bivalents; tetrads are formed.
  • Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
  • then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

  • Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
  • independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
  • in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
  • Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

which of the following steps is an important part of the process by which energy guides human to a sustainable future A) behavio
Tom [10]
Let's think of it like this.  We have an energy crisis, but how can we solve it?  There are three steps.  First, we need to recognize that we HAVE a problem that needs to be fixed.  Then, we need to determine what's causing the problem.  Finally, we need to change how we act in order to solve the problem.  Now, let's look at the options.

Is A correct, leaving our behavior unchanged?  NO: if we know the cause of the problem, we still need to solve it!  What about B: the problems are ignored?  NO: you can't solve a problem unless you know it's a problem.  C?  NO: to solve a problem, you need to find out what's causing it.  Finally, let's look at D: behavior is changed after cause is identified.  This is correct: not only do we know why it's happening, but we're fixing it!

Some members of the Euglenids are photosynthetic, yet they will lose their photosynthetic pigment if left in the dark. True or F
irga5000 [103]

A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE

B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

<h3>What are Euglenas</h3>

Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.

The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed  to grow exponentially for several weeks.

Hence we can conclude that  Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE  while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
