In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.
Answer: false
Explanation:
we can say that the genetic map has 2 options
A …12 mu …X35 …12 mu … p2
with the fact of knowing the location of a single gene we can define the distances that the genes have, as in the previous graph, however when the "A" gene is located in the middle of the map the distance of the X35 gene will no longer be 12 mu with respect to the locus p2 gene and the X35 gene will have 36mu with the locus p2 gene
X35 … 12 mu … A …24 mu …p2
When finding the gene "A" is in one of the genetic maps, we can affirm that the answer is correct
A …12 mu … X35 …12 mu …p2
Answer:
The electrical signal will not be converted into chemical signal.
Explanation:
The synaptic knob is the bulbous enlargement also called synaptic terminal preset at the end of the axon.
The synaptic knob is a living cell and thus contains all the living features but they also contain the vesicles which store the neurotransmitters, therefore, synaptic knob acts as a site which converts the electrical signal into a chemical signal. The released neurotransmitter from the synaptic knob interacts with the post neuron or recipient neuron.
If the mutation develops in the neurons which result in the formation of neurons without synaptic knob therefore the electrical signal will not be converted into a chemical signal and thus signal will stop.

Answer:
The correct answer will be option-A
Explanation:
Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.
The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.
In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.
Thus, option-A is the correct answer.
