Answer:
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
Answer:
Lacks the right key to unlock many cells.
Explanation:
Avian influenza (H5 N1) rarely transmitted from poultry to humans because it lacks the right key to unlock many cells in the upper respiratory tract so due to this action the virus is rarely transmitted to humans. Sometimes it is lethal to humans due to absence of antibodies for this type of virus. It is rarely spread from person to person due to inability to enters the other human body.
Answer:
water is the most abundant molecule in the body
Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. Transport in xylem requires physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.
Answer:
The correct answer is - True.
Explanation:
Degradative pathways are the pathways that provide energy for the anabolic reactions, these are catabolic reaction. An activator protein is a protein that enhance the transcription by binding to DNA.
A transcriptional activator are bind to the enhancers or promoter proximal elements. These are the the DNA binding proteins that regulates the transcription of the DNA molecule.
Thus, the correct answer is - true.
