Answer:
Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.
I hope this helped you!
Answer:
Advantage of gene expression in prokaryotes is it occurs faster than in eukaryotes because transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Whereas disadvantage of gene expression in prokaryotes is that there is no post translational modification and low expression of genes.
Explanation:
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. whereas in eukaryotes, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm.

Answer:
B. the combination of modern genetics and Darwinism.
Explanation:
The modern synthesis refers to the concept which combined the theory of inheritance by Mendel and theory of evolution by Charles Darwin. The theory also used the concept of Theory of germplasm.
The modern synthesis concept came in the early 20th century when the studies were going on Mendel's theory and the evolutionary aspects. The concept led to the formation of new concepts like the macroevolution, microevolution and the evolution affected by mutation of genes.
Thus, Option-B is correct.
