There are many different types of dog breeds, despite the fact that they are all one species, Canis familiaris and all have a co

mmon ancestor, the wolf, Canis lupus. Many breeds, such as the Alaskan malamute and the Siberian husky look remarkably like wolves and even retain some of their habits. Other breeds like the daschund above, do not strongly resemble wolves.
What part of the theory of evolution by natural selection would explain why there are no wild wolves that resemble dachshunds?


A) Natural selection leads to evolution.
B) There is very little genetic variation in all living species.
C) There is over-reproduction in all living species to ensure their survival.
D) Competition favors the most fit organism.

D) Competition favors the fittest organisms. 
This is correct because, in different parts of the world, different organisms need different things to survive, which means if Wolves in Alaska need warm coats to survive, but animals in some parts of America don't, each animal that is the fittest to live in those conditions will survive, while the others with unfavorable genes will not.

What is the type of macromolecule( Carbs, Proteins, lipids, nucleus acid) that changes when amino acid glutamate changes to aspa
Lesechka [4]

Explanation:

Both glutamate C5H9NO4, an amino acid and aspartame C14H18N2O5, an artificial sweetener and dipeptide ester, are digested as protein-like substances; they are made up of the elements C, H, O, N, S. Unlike other naturally occurring saccharide sweeteners, aspartame is not a carbohydrate.

Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.

Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding

Further Explanation:

Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).

  • Similarly, the nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.  <em>Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring. </em>
  • Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.  <em>Basic makeup: C, H, O -with many polar OH groups </em>
  • Lipids function as energy storage and chemical messengers, these include fats, saturated and unsaturated fatty acids with double bonds and steroids and waxes. However, lipids are comprised of fatty acids and glycerol; they do not contain a fixed set of monomers, and unlike the other biological macromolecules, they are not polymers. The arrangement of hydrophobic heads and hydrophobic fatty acid tails can give these non-polar macromolecules hydrophilic and hydrophobic properties<em>.  Basic makeup: C, H, O; non polar- a triple condensation reaction produces the molecules from a triple hydroxyl (OH) alcohol bonded to three long-chain carboxylic acids. </em>
