If the adhesive forces between a liquid and the walls of a capillary tube are greater than the cohesive forces within the liquid

, Select one: A. the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus. B. the liquid level in a capillary tube will rise above the surrounding liquid and the surface in the capillary tube will have a convex meniscus. C. the liquid level in a capillary tube will be flat. D. the liquid level in a capillary tube will rise above the surrounding liquid and the surface in the capillary tube will have a concave meniscus. E. the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a concave meniscus.

Answer:

Option A, the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus.

Explanation:

A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.

A  convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)

Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.

Hence, option A is correct

In eukaryotic gene regulation, RNA interference occurs through:
Anit [1.1K]

Answer:

B. the action of microRNAs that block translation of specific mRNA molecule

C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.

Explanation:

RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.

MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.

RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.

Axons from mPFC neurons synapse onto intercalated cells in the amygdala that contain the neurotransmitter __________.
sammy [17]

The medial pre Frontal Cortex neurons synapting with the intercalated cells of Amygdala contains <u>GABA</u> as the neurotransmitter.

Option a

<u>Explanation:</u>

The Amygdala has two types of nerve cells getting attached with it primarily. They are the fibres from the mPFC or medial pre Frontal Cortex and the vIPAG or ventrolateral periaqueductal grey. These neurons do have different functions on the whole body.

The fibres from the mPFC do have emotional function on the human body whereas the fibres of vIPAG do have an effect on the muscle tone . And it's seen that both the nerve fibres that are getting attached with the intercalated cells of Amygdala do secrete GABA and are inhibitory GAB Anergic in nature.

The potential must be strong enough to send a(n) potential to the CNS.
salantis [7]

It is true that the potential must be strong enough to send a potential to the CNS. The stronger the potential, the more it will excite the transmitter in relaying the message to another neuron, therefore, if this happens, the more will it be easier to pass the message.
