Molecules are defined as the smallest particles of a chemical compound or an element, and are made up of atoms. Cells are made up of semi permiable membranes that only allow selected materials to move in or out of the cell, therefore due to the big size of molecules compared to atoms the membrane doesn't allow their passage in the cell. Therefore the cell doesn't allow most molecules to diffuse passively to the cell. Secondly, molecules that can enter the cell requires specific carriers carriers that will enable entry of small molecules in the cell.
Answer:
C. Primary, secondary, and tertiary structures would be altered
Explanation:
Frameshift mutations refer to the mutations that change the reading frame of the gene. Frameshift mutations are mostly caused by insertion or deletion of nucleotide since addition or loss of nucleotide alters all the codons present downstream of the point of the mutation site. If frameshift mutation occurs at the beginning of the protein sequence, all the downstream amino acids would be altered.
The changed amino acid sequence would alter the primary structure of the protein. Since the secondary and tertiary structure of proteins is determined by interactions between the R groups of amino acids, their polarity, charge, etc., the altered amino acid sequence would also alter secondary, and tertiary of the protein.
Answer:
gravity?
i hope im answering this right-
Explanation:
Water molecules are polar with the oxygen side being, slightly negative and the hydrogen side being slightly positive.
