Answer: Chemical bonding

Explanation: Bonding by sharing electrons is known as covalent bonding and bonding by transferring electrons is known as ionic bonding. Both are a type of chemical bond that bond elements together into molecules.

It sounds like semantic encoding. This basically means teaching a person something that can be applied to some sort of context (hence it describing themselves).

in a phylogeny, information about relatedness is portrayed by the pattern of branching, not by the order of taxa at the tips of

MA_775_DIABLO [31]

On a phylogeny, the number of nodes separating two taxa indicates how closely related they are.

A given taxon typically includes several taxa of lower rank. Taxa are arranged in a hierarchy from kingdom to subspecies. Certain taxonomic categories, which are listed in descending order and include kingdom, phylum (in plants, division), class, order, family, genus, species, and subspecies or race, are universally accepted for the classification of protists, plants, and animals.

Kingdom, phylum, class, order, family, genus, and species are the orderly groups, going from largest to smallest. 2. Each level is referred to as a taxon (plural: taxa) or taxonomic category in taxonomic nomenclature.

Pancreatic amylase is a digestive enzyme that digests starch in the small intestine. pancreatic amylase's optimum pH is slightly

Rainbow [258]

Answer:

Tube 3

Explanation:

Pancreatic amylase's optimum pH is basic, NaHCO3 is a base so it will provide the optimum pH for the enzyme to catalyse the breakdown of starch.

In tube 1 there will not be the breakdown of starch as there simply isn't any enzyme to break it down.

In Tube 2, the enzyme pancreatic amylase will most probably become denatured (loss of shape), as HCl is acidic which causes it to lose shape causing a change in the active site and will never be able to catalyse the breakdown of starch.

Hope this helps :)

You eat a candy bar to get you through a late-night studying session. Your body quickly begins to break down the macromolecules

irga5000 [103]

Answer:

a. First Step: The sugars are broken down to simple glucose molecules and the proteins and lipids are broken down to acetyl-CoA molecules. No energy is produced in this first step.

b. Second Step: Glycolysis converts the glucose to two molecules of pyruvate. Six ATP molecules are produced in this step.

c. Third Step: Oxidation of each pyruvate produces two molecules of acetyl-CoA. Six ATP molecules are produced in this step.

d. Fourth Step: Two acetyl-CoA molecules go through the Krebs (citric acid) cycle. Twenty-four ATP molecules are produced through this process.

e. All of the above steps are part of the break down of the candy bar's macromolecules.
