Trey is looking at a cell under the microscope. It is attached to many other cells, and it has a nucleus and membrane bound organelles. It has no cell wall. In which kingdom should this organism be classified?

Answers

Answer 1
Answer:

Answer:

The most appropriate kingdom would be Animalia.

The common characteristics of the kingdom Animalia may include:

  • The organisms of this kingdom are eukaryotic. Thus, they have a well-developed nucleus and other cell organelles like mitochondria et cetera.
  • They are multi-cellular organisms, that is, they are composed of many cells. They may show body organization like cells→ tissues→ organs→ organ systems→ organism
  • Unlike plants, they lack chloroplast and cell walls.
  • They are usually heterotrophic.

Thus, the cell can be classified as Animalian cell.

Answer 2
Answer:

Answer:

Explanation:

Animalia

What are the levels of protein structure?

The Primary structure of proteins is the linear ordering of amino acids, bound by Covalent,peptide bonds to form primary structure.

Secondary structure refers to local folded structures formed due to hydrogen bonding  between the amine and carboxyl group of the peptide link of polypeptide chain.

These structure present in two forms like α – helix form which is a polypeptide chain forms  hydrogen bonds by twisting into a right-handed screw with the -NH group of each amino acid residue.

The β – pleated sheet structures are the peptide chains are stretched out ,laid side by side together by intermolecular hydrogen bonds. The structure resembles the pleated folds of drapery.

Tertiary Structure of Protein refers to folding of the secondary structure by H-bonds, electrostatic forces, disulphide linkages, and Vander Waals forces stabilize this structure. Quaternary Structure of Protein refers to spatial arrangement of various tertiary structures.

Which energy transfer is least likely to be found in nature ? A- consumer to consumer
B- producer to consumer
C-host to parasite
D- predator to prey

Answers

The energy transfer that is least likely to be found in nature is predator - prey. Details about energy transfer can be found below.

How is energy transferred in nature?

Energy is transferred in nature when organisms feed on one another.

For example;

  • Producers, which are the initiator of the energy transfer are fed upon by consumers

  • Consumers like herbivores are also fed on by other consumers like carnivores

  • Parasitic organisms feed and derive nourishment from their host

However, the transfer of energy does not occur in the direction of a predator to prey but occurs the other way around.
