Answer:
RNA interference
Explanation:
Interference RNA is a mechanism of post-transcriptional silencing of specific genes, so that small RNA molecules complementary to an mRNA lead to its degradation, thus preventing its translation into proteins.
Gene silencing by interfering RNA is induced by small double stranded RNA molecules of 21 to 27 nucleotides called siRNA. These siRNAs undergo a series of processes in the cell as a result of which their double stranded RNA unfolds in a sense strand and an antisense strand. The antisense strand binds to the mRNA chain specifically for base complementarity, causing the resulting complex to be recognized by cellular and degraded mechanisms. Each siRNA is highly specific for the target nucleotide sequence to which it degrades. This phenomenon of gene interference occurs naturally in the body, being involved in the development and defense against viruses.

A is mitosis because when a mitosis happen it always identical to the original cell it's like a clone.
And B is meiosis is different because when a mother have a child the child is not likely to look exact the same has the parent so they different.
Answer:
yes it does
here is a more clearer explanation
Explanation:
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
Some other examples of specific heat capacities are:
Material Specific heat capacity (J/kg/°C)
Brick 840
Copper 385
Lead 129
Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature. Brick will take much longer to heat up and cool down. This is why bricks are sometimes used in storage heaters as they stay warm for a long time. Most heaters are filled with oil (1,800 J/kg°C) or water (4,200 J/kg°C) as these emit a lot of energy as they cool down and, therefore, stay warm for a long time.
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C).
Answer:
What is the main function of chloroplasts in a cell?
Chloroplast houses the chlorophyl that gives green pigment which is used by plant to trap sunlight and undergo photosynthesis
