Answer:
The correct option is A. Matter is conserved during the burning of wood
Explanation:
One of the major theories of matter states that the amount of mass at the start of a reaction is equal to the amount of the mass at the end of the reaction.
As in Joan's study, he shows that the amount of carbon atoms remain 840 during each of the combustion reactions. The number of carbon atoms in wood at the start of the reaction was equal to the number of carbon atoms in carbon dioxide at the end of the reaction. Hence, Joan's model supports the theory that matter is conserved during the burning of the wood.
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
b) A population first divided into two parts, then three parts, and then four parts, until a description identifies a single member.
