<h2>Daphnia - Water invertebrate </h2>
Daphnia obtain chemical energy by absorbing blucose from algae. Then it is used in cellular respiration to produce nicotinamide adenine dinucleotide(NADP) which is chemical energy. Daphnia require chemical energy in the form of NADP. So, it uses gills to extract oxygen from water (H2O) to help it obtain chemical energy.
Answer:
A. Preganglionic sympathetic fiber
Explanation:
The fibers of the central nervous system (CNS) that innervate the parasympathetic ganglia are referred to as preganglionic fibers. For example, preganglionic nerves are found in the airways, and function for controlling the breathing movement. Both parasympathetic and preganglionic sympathetic fibers use acetylcholine as neurotransmitter (i.e., they are cholinergic fibers) and are myelinated. Moreover, different vasoactive mediators including histamine and prostaglandin are able to improve ganglionic cholinergic transmission.
Hydrogen would be the answer to this.
A is the answer. I had this question earlier and went back to make sure and I got it right.
Answer:
The options are not given but the most probable answer is - Lysozyme
Explanation:
Bacteria are commonly used in many genetic research program. So for genetic research, the nucleic acid of bacteria has to be taken out for the molecular studies.
So to take out the genetic material of bacteria first their cell wall has to be broken and destroyed. Lysozyme is the enzyme that targets the peptidoglycan layer in the bacterial cell wall and breaks it which causes cell wall lysis in bacteria.
So lysozyme is the enzyme which can be used to lyse the bacterial cells for nucleic acid isolation.
