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.
Answer:
pretty sure it's d. invasive species
Explanation:
the reason a species is called invasive is if it is incredibly difficult to get rid of and the population is growing out of control quickly. the characteristics that was given were likewise to the behavioral problems of an invasive species.
He would say that Lamarck's theory is wrong. Lamarck's theory stated that traits that are used are passed on to the offspring. In other words, if an organism changes during its lifetime in order to adapt to its environment, then its changes will be passed on to its offspring. This is wrong because this means that organisms pass on traits based on genetic information and not based on the environment of the offspring.
Hope this helps.
Answer:
A. Weather.
Explanation:
Usually or average are terms that are often associated with weather conditions.
Weather is the average atmospheric conditions prevalent in a particular place over a short period of time.
When forecasting weather, predictive terms like usually are employed to denote expected weather events
Answer:
The correct answer is c) The first statement is true; the second is false.
Explanation:
To be able to perform its role, a hormone must bind a specific receptor in its target cell. The receptor can be located inside the cell (in cytosol) or in the surface of the cell (transmembrane receptor). By regulating the expression of the receptor, the target cell regulates the hormonal activity.
The number of hormone receptors in a cell is not constant, it can vary depending on sereral factors, such as the age of the organisms, the effect of several drugs, mutations or diseases.
