Answer:
Molecular genetic approaches to the study of plant metabolism can be traced back to the isolation of the first cDNA encoding a plant enzyme (Bedbrook et al., 1980), the use of the Agrobacterium Ti plasmid to introduce foreign DNA into plant cells (Hernalsteens et al., 1980) and the establishment of routine plant transformation systems (Bevan, 1984; Horsch et al., 1985). It became possible to express foreign genes in plants and potentially to overexpress plant genes using cDNAs linked to strong promoters, with the aim of modifying metabolism. However, the discovery of the antisense phenomenon of plant gene silencing (van der Krol et al., 1988; Smith et al., 1988), and subsequently co‐suppression (Napoli et al., 1990; van der Krol et al., 1990), provided the most powerful and widely‐used methods for investigating the roles of specific enzymes in metabolism and plant growth. The antisense or co‐supression of gene expression, collectively known as post‐transcriptional gene silencing (PTGS), has been particularly versatile and powerful in studies of plant metabolism. With such molecular tools in place, plant metabolism became accessible to investigation and manipulation through genetic modification and dramatic progress was made in subsequent years (Stitt and Sonnewald, 1995; Herbers and Sonnewald, 1996), particularly in studies of solanaceous species (Frommer and Sonnewald, 1995).
Water would move out of the cells of the microorganisms by osmosis and the cytoplasm would become dehydrated, killing the cells.
The brine is a hypertonic solution, thereby "pulling" the water out of the bacterial cells.

Answer:
All the above keywords conclude a process used by plant which is known as photosynthesis. This process is done by all the green plants in the presence of sunlight and also in dark.
Explanation:
Photosynthesis is defined as the process by which all the green plants prepare their food in the presence of sunlight by the use of water, minerals and carbon dioxide. Chloroplast provides green color to the plant and it is also known as photosynthesis site. Glucose is the product and oxygen is a byproduct of photosynthesis.
Calvin cycle is a type of photosynthesis that is also followed by some. the energy released is counted in the terms of ATP which is also known as adenosine triphosphate. Sunlight plays a role of catalyst in the formation of food by the process of photosynthesis
Answer:
It is Isotonic to the fish egg solution
Explanation:
It is Isotonic because Isotonic is a solution that has the same solute concentration with another solution I.e the amount of solute in one solution is the same with the other. This slow the free flow of solutes in equal part through the semipermeable membrane from one solution to the other.
