Answer:
Explanation:
The unicellular organisms basically classified into prokaryotes and eukaryotes. In case of bacteria the nucleus was completely absent but the replication and translation process were combined together. so there is no need of complexity. The genome is under control of one replication of origin i.e. the replication of DNA and translation for proteins synthesis takes place simultaneously and again no complexity. The organism is depend on these proteins and DNA for different purposes like fission, energy production etc.
If we think about Eukaryotes there is separate boundary for DNA and protein synthesis Nucleus and rest of cytoplasm with organelles. The complexity increases because of functional variations and functions occur at different times. So the whole genome replication is not needed every time and there are separate Origin of replications for segments of DNA (genes). Along with these there are non-functional DNA segments (introns functionally they won’t give proteins). To eliminate them there is a separate process after mRNA synthesis called post transcriptional modifications. After this protein synthesis takes place at cytoplasm. There is one more check point called post translation modification where protein modification (functional diversity) allocated. To adapt the changing environment, stress, reproduce and for any functions there is a wide diversity if we compare prokaryotes and eukaryotes.
I think it is because they can graph all their information
5. The genetic contributions of the oarents vary between organisms within a species
Answer:
The correct answer is C. gases.
Chemical reaction is the process by which one or more substances are converted into different substance or substances.
The substances which undergo chemical reaction are called as reactants while the substances which are produced by the reaction are called as products. During chemical reaction, chemical bonds of substrates undergo breaking and formation process to form an entire new product which may have same or different physical and chemical properties as compared to substrates.
Energy is either used or released during the chemical reaction. When the energy is used, it is termed as endothermic reaction but when the energy is produced by the reaction, it is termed as exothermic reaction.
Lastly, gases may or may not participate in a chemical reaction.
