Biological systematics and ethnoscience differ in what way? Ethnoscience and systemics both attempt to examine how all societies
Phoenix [80]

Answer:

Ethnoscience attempts to understand how people understand the world and plant systematics attempts to use classification to document evolutionary relationships between organisims

Explanation:

Ethnoscience is a study about how people see the world around them. This study shows how different people understand the nature and life under the influence of different cultures.

On the other hand, systematics shows relationships among living things through a certain period of time. Those relationships are graphically represented by phylogenetic trees or cladograms.

Determine whether the following events occur during initiation, elongation, or termination. This is regarding protein synthesis.
erik [133]

Answer:

The provided events can be classified as:

Initiation

  • In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
  • In E. coli, mRNA binds to the 30S ribosomal subunit.

Elongation

  • In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
  • Initiator tRNA enters the P site.
  • In E. coli, EF-Tu hydrolyzes.
  • Translocation occurs

Termination

  • The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site

Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).

It is divided into three stages:

Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.

Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next  codon.

Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.

Match the following carbohydrate molecules with the class of molecule that they belong to:
Vlad [161]

<span><span> (I) Glucose; is C
(II) Starch; A
(III) Sucrose</span> B

A) Polysaccharides
B) Disaccharides
C) Monosaccharides

</span><span><span>Monosaccharide, disaccharides, and polysaccharides are the three major categories of molecules in Carbohydrates. </span>

Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.

Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose  (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.

<span>Polysaccharides are formed when another monosaccharides is bonded to the disaccharides. This bond is called glycosidic bond. Two major polysaccharides are starch and glycogen. Starch is made by plants while glycogen is made by animals. Polysaccharides' major function is to immediately release energy from its storage. When glucose is consumed, some of them are stored and will only be released when the body needs it to satisfy the body's immediate need of energy.</span> </span>
