Answer:
The solid particles will be trapped behind on the strainer while the liquid molecules will pass or filter through.
Explanation:
Filtration is a process of separation of mixtures involving an insoluble solid and a fluid such as liquids or gases using a filtering medium such as paper or cloth or any other material. During the process, the liquid molecules pass through the filtering medium whereas the solid particles are not allowed to pass through but are retained by the medium. The reason is that the pores on the filtering medium are only small enough for the liquid molecules to pass through but not the solid particles.
An example of a mixture that can be separated through filtration is a suspension of chalk and water. Also, a mixture of water and solid particles such as water and tea leaves can also be separated using a strainer with cloth.
In the question, if a mixture of insoluble solids in a liquid is passed through a strainer with cloth, the solid particles will be trapped behind on the strainer while the liquid molecules will pass through.
Answer:
The right answer is A)The primary structure of a protein is the order of amino acids in a polypeptide, as coded for in the DNA of a gene.
Explanation:
Proteins are aminoacids´s polymers. There are 20 different aminoacids that differs only in their R groups. There are four kind of protein structures:
1) Primary structure: it refers to tha secuence of aminoacids in the protein and is defined by DNA.
2) Secondary structure: it describes the situation in which we can identify repeated segments along the polypeptid chain. There are two secondary structures: alpha helix and beta pleated. This two conformation are held together by interactions between peptidic groups. R groups can interact only if they are small.
3) Tertiary structure: is the three-dimentional conformation of the polypeptid and it is stabilized by hydrogen bonds, electrostatic interactions, hydrophobic interactions and disulphide bonds. Stabilizing bonds can be between peptidic groups (peptide bond).
4)Quaternary structure: it applies for that proteins conformed by different subunits. It describes the conformation and interaction between these subunits in the polypeptid.
