<span>The right answer is: A
A) The molecule is digested by exonucleases because it is not protected at the 5' end. (correct)
B) The molecule is digested by restriction enzymes in the eukaryotic cell's nucleus. (false it is digested by exonucleases due to the absence of the 3'cap and the 5'tail)
C) The mRNA cannot exit the nucleus to be transcribed without the 5' cap and poly-A tail. (false, to be TRANSLATED and not to be transcribed)
D) The mRNA molecule attaches to a ribosome and is translated at a much slower rate. (false, it doesn't have a role to play in translation)</span>

Answer:
A.Earth's early atmosphere lacked oxygen, which multicellular organisms need to break apart food
Explanation:
One important feature that led to the development of multicellular organisms was the rise of oxygen-producing photosynthetic bacteria. Prior to this development, the unicellular organisms (anaerobes) then present on Earth obtained energy from inorganic fuels.
However, with the presence of oxygen in the atmosphere, a shift was observed as organisms that could obtain energy from the reduction of energy became predominant. This unicellular aerobes later paved way for the evolution of multicellular aerobes.
Physical Geography is a sub-train of two significantly bigger fields of study - Geography and Earth Sciences. The primary reason for Physical Geography is to clarify the spatial attributes of the different common wonders related with the Earth's hydrosphere, biosphere, climate, and lithosphere
Answer:
Science causes the development of economy, health, infrastructure and education.
Science helps finding new knowledge and technologies.
Explanation:
Science can lead to the development of economy, health, infrastructure and education. The development in these fields makes the people of that society are more advanced due to education and having good health and financial conditions.
It’s important to know that science is a way to help in finding new knowledge and technologies. the new knowledge helps in finding new technologies which minimize the adverse affect of that technologies on the environment and also these technologies reduce human efforts and make our work easier.
