Answer:
Electron microscope
Explanation:
Instead of using light, it utilized a beam of electron for illumination. Because an electron beam has a shorter wavelength than light (up to 100, 000 times shorter), they have a higher resolution power and are therefore able to view sub-cellular structures including DNA.
Biological augmentation is a process that uses organisms to add essential materials to a degraded ecosystem. It involves the addition of archaea, or bacteria cultures required to speed up the rate of degradation of a contaminant, this is supplementation application of non-toxic, natural, beneficial microbes, enzymes and minerals to enhance the rate of degradation.
The question is incomplete as it does not have the options which are:
A) relay molecule
B) transducer
C) signal molecule
D) response molecule
Answer:
C) signal molecule
Explanation:
The transmission of signals in the neurons takes place in the form of electrical energy and chemical energy. The signals get transmitted in the form of electrical signals inside the neurons but when the signals have to be passed on to the next neuron on the pathway then the electrical signals get converted into the chemical signals.
The electrical signals cause the release of the chemical signals molecules called neurotransmitter from the synaptic vesicles in the presynaptic neuron and also opens the gated ion channels at the terminal.
The neurotransmitter thus acts as a signal molecule in the transmission of a signal through neurons.
Thus, C) signal molecule is the correct answer.
The liverworts are a group of simple plants which are flowerless, spore producing plant.Their spores are produced in small capsules.
An example of liverwort is :
b. Marchantia
Chlorophyll is the source of carbon in the sugar molecule
