Explanation:yeah
Answer:
Each part of the mixture has the same appearance.
Explanation:
Homogeneous mixture consists of substances that mix evenly. Therefore has same appearance.
Transmembrane proteins are found in the plasma membrane. Hydrophilic regions are embedded

Approximately 20-80% of the cell membrane is composed of lipids, the rest, is made up of protein. The lipid layer of the membrane gives it flexible and permeable characteristic. While the protein part assists in transport of molecules it needs to survive.<span>

Answer:
A zinc finger is also known as zinc-binding repeats or ZnF that are molecular scaffold which is characterized by the coordination of Zn²⁺ ions so it can stabilize the fold.
The zinc fingers consist of several amino acid sequence 2 histidine and 2 cysteine residues at intervals. These residues bind to the zinc atom covalently and form finger-like motifs.
They are a major family of eukaryotic transcription factors. These are identified in a significant regulatory state such as developmental control genes and proto-oncogene by binding to the DNA, RNA, or protein.
