Calcium chloride is a salt, which is used in household and in industries. The calcium chloride is an ionic compound which can be split in ionic form such as one cation (Ca2+) and two anions (Cl-). Therefore, the cation in the CaCl compounds is Ca2+ ions.
Answer:
The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.
Explanation:
Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.
To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a <u>polysome </u>and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.
Answer;
-Facilitated diffusion
Explanation;
Facilitated diffusion involves spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
-For instance; in the cell, examples of molecules that must use facilitated diffusion to move in and out of the cell membrane are glucose, sodium ions, and potassium ions. These molecules pass using carrier proteins through the cell membrane without energy along the concentration gradient.
Answer:
Experimental design means planning a set of procedures to investigate a relationship between variables, or experimental design refers to how participants are allocated to the different groups in an experiment. The types of design include repeated-measures, independent-groups, and matched pairs design.
Annotated bibliography provides specific information about each source you've used. As a researcher you have become an expert on your topic: you have the ability to explain the content of your sources, assess the usefulness, and share this information with others who may be less familiar with them.
Annotated bibliography is a list of citations to books, articles and documents.
