Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.

The model shows a cellular process that occurs in every cell in eukaryotic organisms.
Whitepunk [10]

Answer:

The correct answer is - create polypeptide and eventually proteins for gene expression.

Explanation:

This model is representing the translation process in protein synthesis which takes place in the cytoplasm of the cell and results in forming proteins from the information carried by mRNA from DNA in a code. The translation is the process that translates the code, carried out by mRNA with help of ribosome and tRNA, into a chain of amino acids called polypeptide chain that forms eventually in protein.

1. mRNA strand and ribosome present of ER translate codes into a protein.

2. Amino acids are transferred by the tRNA molecules to the ribosomes.

3. mRNA and tRNA bases are paired and amino acids are left behind to create polypeptide.

A single-celled eukaryotic organism that is neither a consumer nor a decomposer would most likely be classified in _____.
DedPeter [7]

A single-celled eukaryotic organism that is neither a consumer nor a decomposer would most likely be classified in Kingdom Protista.

Kingdom protista:

  • The classification of a third kingdom, separate from animals and plants was first proposed by John Hogg in 1860 as the kingdom Protista; in 1866 Ernst Haeckel also proposed a third kingdom Protista as "the kingdom of primitive forms".
  • Originally these also included prokaryotes, but with time these were removed to a fourth kingdom Monera.
  • In the popular five-kingdom scheme proposed by Robert Whittaker in 1969, Protista was defined as eukaryotic "organisms which are unicellular or unicellular-colonial and which form no tissues", and the fifth kingdom Fungi was established.
  • In the five-kingdom system of Lynn Margulis, the term protist is reserved for microscopic organisms, while the more inclusive kingdom Protoctista (or protoctists) included certain large multicellular eukaryotes, such as kelp, red algae, and slime molds.
  • Some use the term protist interchangeably with Margulis's protoctist, to encompass both single-celled and multicellular eukaryotes, including those that form specialized tissues but do not fit into any of the other traditional kingdoms.

Why do cells need to replicate their DNA?
ch4aika [34]

Answer:

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Explanation:

Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.
