This is the best 3 answer about the fluid mosaic structure of a membraneFirst, The diverse proteins found in and attached to membranes perform many important functions. Second, The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. Third, Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
Answer:
All of the above
Explanation:
Digestion or breakdown of food in our body can either be physical/mechanical or chemical/enzymatic. As rightly stated in this question, the manual breakdown of food by the teeth is not enough, chemical digestion must occur via the aid of proteinous substances called ENZYMES. Enzymes, which are secreted by certain organs in the body, do the following:
- They speed up the rate of chemical reactions by lowering the activation energy needed for the chemical process, allowing more productivity.
- Enzymes help break down various sugars that can then be absorbed e.g amylase helps break down starch, proteases break down proteins, lipases break down lipids etc.
Answer: They contain substances/substrates in specific ways that heighten the chances of the chemicals reacting with each other

Answer:
The correct option is Incomplete dominance.
Explanation:
Incomplete dominance describes the situation in which the phenotype of heterozygous is different from that of their respective homozygous. It means that when both parents are homozygous for some feature, each expressing a particular phenotype, their heterozygous descendants have a phenotype that will be between the phenotypes of their parents. In the present case, the woman has curly hair ( dominant homozygous) and the man has straight hair (recessive homozygous), but the child have wavy hair (heterozygous), not curly nor straight.
