Answer:
The lunar phases gradually change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. The Moon's rotation is tidally locked by Earth's gravity; therefore, most of the same lunar side always faces Earth.
Explanation:
Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
Answer:
Begin to cross the membrane while still being synthesized-C
Explanation:
The Endoplasmic Reticulum is a part of the endomembrane system of the cell which is mostly reponsible for the synthesis and modification of proteins, although synthesis of lipids in plant and animal are carried out here
For more synthesis of proteins, it
needs to be further transported into the Rough endoplasmic reticulum- the designated site for secretion after synthesis of proteins.
Also it has been found out that when this proteins enter the Endoplasmic Reticulum, they start to cross the membrane while still being synthesized.
Answer:
When cells split and increase they do this very important thing in order tonmake the new cells exactly the same as the previous before them. Each cell makes more of all it's genes. Then each one.splits into two with one group of genes in each one of the new cells. During the process they make sure that all are copied correctly.
RNA nucleotides form complimentary base pairs with DNA bases. Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.
Explanation:
The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.
Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.
This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.
