Answer:
miRNA ( micro RNA )
Explanation:
The small RNA molecule that interfere with gene expression are miRNA. The miRNA is micro RNA that are non-coding molecules of RNA. These small RNA regulate gene expression after transcription (post transcription).
The miRNA binds to 3' UTR region (untranslated region ) and halt the process of protein production and thereby silencing mRNA.
Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
H S G Low temperature and High temperature.
When H is negative and S positive and G negative there will be spontaneous low temperature and spontaneous high temperature. When H is negative, and S is negative and temperature dependent then the low temperature will be spontaneous and high temperature will be non-spontaneous. When H is positive and S is positive then the temperature dependent and low temperature are non-spontaneous and high temperature will be spontaneous. When H will be positive and S is negative then G will be positive, the low temperature will be non-spontaneous and high temperature will also be non-spontaneous.
Palm trees mostly live in the Desert..
Hope i helped. If you need anything else ask me..
I think the correct answer from the choices listed above is option A. In plants, the purpose of auxins is to produce phytochrome. The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant. Hope this answers the question.
