Answer:
Charles Darwin
Explanation:
Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.
In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.

Water is a polar molecule bcz oxygen bears partial negative charhe and hydrogen bears partial positive charge. This results in extensive hydrogen bonding btween water molecules. The temperature is another way of saying the average kinetic energy of gases liquids or vibration for the case of solids. The Heat Capacity is the ability of matter to absorb thermal energy. Water's specific heat is defined as one. Water has high heat capacity because it can store heat in many ways. Which makes its capacity higher than anything
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.
