How many atoms lined up side by side would equal the thickness of a book page?

1 answer:

3 0

More than 1 million atoms lined up side by side would equal the thickness of a book page. The modern atomic theory was proposed in 1803 by English chemist John Dalton. His premise is based on the fact that all elements are composed of atoms. An atom is defined as the smallest part of an element. It also keeps the identity of the element. Individual atoms are very small. Most elements in their pure form exist as individual atoms. Some elements are made up of groups of atoms.

Is the lumen of an artery, capillary or vein, large or small? Why?

SOVA2 [1]

Answer:

Arteries have thick walls composed of three distinct layers (tunica) Veins have thin walls but typically have wider lumen (lumen size may vary depending on specific artery or vein) Capillaries are very small and will not be easily detected under the same magnification as arteries and veins.

The s phase of cell cycle is very important as a cell can not divide without it

Leona [35]

Answer:

TRUE

Explanation:

S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.

This interprets an RNA message into a string of amino acids called a polypeptide. Either single polypeptide or many polypeptides

vovangra [49]

Answer:

The correct answer is - translation

Explanation:

The translation is the second process involved in the protein synthesis in which mRNA that was encoded the genetic information from the DNA code during the transcription process, produces the amino acid sequence with the help of ribosome and tRNA.

These RNA messages or codes are decoded by the ribosome that produces a specific sequence of codes that form specific amino acid decided by the triplet code they produces. These amino acids together form polypeptides chain and single polypeptide or many polypeptides working together make up a protein.
