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.

Describe the route of a reflex impulse in the somatic system
Sholpan [36]
Take for example - you touching something sharp and instantly moving your hand away.

Sensory neurons in your fingers detect the external stimuli of the sharp object and send a nerve impulse to the spinal cord (does not reach brain) and is sent back to a motor neurone - attached to an effector that moves the muscle and moves the hand away. This is a rapid reflex action and involuntary.

Some desert beetles can live without ever drinking liquid water. They survive on "metabolic water," which is water formed during
anygoal [31]

Answer:

Metabolic water is a water obtained from eating other organisms.

Explanation:

Water is a by product that is gained in the process of cellular respiration. In respiration process, food molecules are broken down in the mitochondria of the cell for generating energy in the form of Adenine tri phosphate (ATP). With this ATP, water and carbondioxide is also produced. Carbondioxide is removed from the body while water is used in different processes. So desert beetle takes water from eating food substances.
