Answer:A, B, C
Explanation:
A. The phospholipids are arranged in bilayers withe the Polar head groups oriented towards the extracellular side and the cytoplasmic side with a hydrophobic core.
The plasma membrane also contain membrane protein
B. Some Integral protein are Transmembrane protein the span the membrane and provide a hydrophilic channel and are selective for particular solute such as enzymes, antigens, hormones
The peripheral protein exit on the surface of the bilayer the serve as signal protein
C. The membrane lipid bilayers are not static or rigid. They show free lateral movement of its components hence the membrane is fluid in nature. Fluidity enables the membrane to perform endocytosis and exocytosis
Answer:
The insect pictured is in the order coleoptera
Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would
- The amount of food increased or decreased
- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa
Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.
The answer is Desalination. Desalination is the process of removing minerals from salt water. Most ocean-water consumption and supply are most likely to be very particular in this places like USA, Europe, Africa and UN. Desalination depends on the capacity and facility of the place.
