An elliptical galaxy is figureless, bright galaxy that is elliptical in shape. A globular cluster is spherical constellation of stars that acts like a satellite orbiting a galaxies core.Answer A collection of from two to several hundred galaxies which are much more densely distributed than the average density of galaxies in space.well the main difference is that in a paralell system there is multipe computing units (cpu) working in one node(they share memory ,attached devices ,storage...) to accomplish a computing goal in a clustered there is multiple nodes each has its own resources running its own copy of os (susually connected via lan) to accomplish a computing goal.A constellation is a pattern of several stars that make a picture. A galaxy is a huge mass of billions of stars, dust and gas that is gravitationally.A galaxy is a massive group of stars and other elements, such as gases and dust, that are part of one system. Think of our solar system, but on a much more massive scale. Having said that all the stars in a constellation are far from each other, the stars we see are all part of the one galaxy, the Milky Way. We are all bound by gravity. Our solar system and the many of the stars that we see are on the edge of the Milky Way. If you are in an area that is free from light pollution, on a clear night you can see a long dusty looking stream in the sky that is part of the more populated part of the <span>Milky Way. hope that helped</span>

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

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

Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.

Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
