I'd appreciate if you attached the article as well. But i'm 90% sure it's option D. A quick search reveals that it was dubbed Black Saturday due to rapid fire growth within Yellowstone park. Option D is really the only one that relates to that at all.

Hope this helps!

Gelneren [198K]
A transverse section cut is a cross section took by slicing, really or through imaging techniques, the body or any part of the body structure, in a horizontal plane, a plane that crosses the longitudinal axis at a right angle. In other words, it divides the body into superior and inferior parts which is also known as the top and bottom parts.

Scurvy is a disease that until the nineteenth century was common among sailors and others whose diets were deficient in vitamin
alina1380 [7]
<h2>Scurvy </h2>

Explanation:

(a) Collagen is the major structural component of cartilage,bones and tendons

  • The basic unit of collagen is tropocollagen and each tropocollagen consists of three coiled left handed polypeptide chains called α chains
  • Generally each α chain consists of a repeating tripeptide sequence called: G-X-Y
  • Here G represents glycine; X represents proline and Y represents hydroxyproline
  • Rigidity of collagen molecule is due to presence of proline and hydroxyproline
  • Hydroxylation of proline is catalysed by prolyl hydroxylase enzyme which use ascorbate,α ketoglutarate and oxygen
  • α ketoglutarate is oxidatively decarboxylated to form carbon dioxide and succinate
  • Sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues includes: tissue levels of ascorbic acid is low;  enzyme prolyl hydroxylase is inactive;  proline is not hydroxylated;  the triple helix is inadequately stabilized; collagen breaks down;  defects in tissues that depend on collagen ; tissues that depend on collagen are subject to breakdown and bruising

(b) Sailors are no longer susceptible to scurvy because fresh fruits which are the source of vitamin C source are available now

British sailors called "limeys" to this day,this term reflects the British navy's use of limes

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.
sveta [45]

Answer:

<u>Starch</u> is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

<u>Cellulose </u>is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

<u>Glycogen</u> is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.

m_a_m_a [10]

Answer:

12 : 3 : 1

Explanation:

According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and  1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.

<em>Dihybrid cross for heterozygous summer squash:</em>

                    WG         Wg            wG            wg          

    WG      WWGG   WWGg     WwGG     WwGg

    Wg       WWGg   WWgg     WwGg      Wwgg

    wG        WwGG    WwGg     wwGG      wwGg

      wg       WwGg    Wwgg     wwGg        wwgg

   Genotypes:

   W-G-  and W- gg  = white = 12

    ww G- = yellow = 3

     ww gg = green = 1
