Answer:
natural selection
Explanation:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Answer:
Newton's Third Law of Motion
Explanation:
According to the given condition, the rocket is launched into space and it exhausts gases in the opposite direction of its movement. This condition is an example of Newton's Third Law of Motion. According to that, an action has a reaction but in an opposite direction. More precisely, if an object exerts a force on the other object, the second object will also exert an equal forceback on the first object. This condition satisfies what is mentioned in the statement and thus, it is an example of Newton's Third Law of Motion. Mathematically, it can be written as
I have attached a figure for better understanding.
Answer:
We depend on them to convert carbon dioxide into oxygen. And also for food energy.
Explanation:
Answer:
a. MicroRNAs (miRNAs) bind to complementary sequences in mRNA and block its translation.
b. Piwi-associated RNAs (piRNAs) reestablish appropriate methylation patterns in the genome during gamete formation.
Explanation:
MicroRNAs
These are the small non-coding RNA molecule. These RNA consist of about 22 nucleotides. MicroRNAs are found in animals, plants and some viruses,
MiRNAs function
MicroRNAs also represented as miRNA function through base-pairing with complementary sequences of mRNA molecules. Due to this base pairing it functions as RNA silencing and regulation of gene expression.
Piwi-interacting RNA
piRNA expressed in animal cell. piRNA are the small non-coding RNA molecules which form RNA-protein complexes.
Piwi-interacting RNA Function:
Function of these complexes are epigenetic and post-transcriptional silencing of transposons.
Small interfering RNA :
siRNA molecules are the small pieces of double-stranded (ds) RNA. There length is about 21 nucleotides long. siRNA have 3' (3 prime) overhangs
Small interfering RNA Function:
siRNA overhangs are used to "interfere" protein translation. They perform this function by binding and degradation of mRNA at specific sequences
