Answer:
C. the nuclei
Explanation:
All of our dna is stored in the nuclei.
Answer:
The series of molecules through which excited electrons are passed down thylakoid membrane is called electron transport chain.
In electron transport chain, the transfer of electron occurs from the element which loses electron to the element which receives electron through a membrane like structure called thylakoid membrane . This occurs in redox reaction means one atom is reduced i. e. gain electron and other is oxidized i. e. loses electron.
Answer: Option B. are able to drift about in the plasma membrane.
Explanation:
Membrane phospholipid are having a amphiphilic structure which contains a hydrophilic "head" consisting of a phosphate group and two hydrophobic fatty acid "tails" that are connected to a glycerol molecule.
In contact with water, membrane phospholipid hydrophobic tail avoid interaction with water molecules and allow to drift about in the plasma membrane. the hydrophilic heads line up against each other and forms lipid bi-layer that faces towards water.
The movement of membrane phospholipid forms the fluid mosaic model,in which lipid molecules act as solvent and proteins embedded in it. This allows the proteins and lipid to move across plasma membrane.
Hence, The structural property of membrane phospholipid makes them able to drift about in the plasma membrane
Answer:
b, the definition of an ion is a charged atom or molecule
When bacteria enter your body through an opening (wound,nose,mouth) they reproduce very quickly.
