Plant storage polyglucan that gathers in plastids is called starch. It is used to store extra glucose. Therefore, option (C) is correct.
What is the main role of starch in plants?A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. . It is made up of two polymers with different structures, amylose and amylopectin, and it serves a variety of roles in influencing plant yield. Most green plants synthesize this polysaccharide as a form of energy storage. It prevents carbon deprivation at night in leaves by acting as a buffer.
In order to provide the plant with a reserve food supply, starch is synthesized in the green leaves of plants using extra glucose produced during photosynthesis. The stroma of the chloroplasts and the cytoplasm of leaves both store starch.

After a natural disaster such as a hurricane or tornado, what will happen in the damaged ecosystem?
Answer:
Depending on the type of natural disaster, the ecosystem will be more or less damaged.
Explanation:
After a huracane or tornado the balance or homeostasis of the ecosystem will be very damaged. Biotic (all living organisms) and abiotic (non-living organisms) will be detroyed, killed, relocated and /or lost. Due to this situation, it will take a while for the ecosystem to recover.
Depending on the damage of the natural disaster and the capacity of recovery ( resilence), this ecosystem will take long time or short time in being recuperated. In terms of nature, primary species will arrive first, then secondary, and this "re-poblation" will promote the recuperation of the ecosystem.

Which of the following elements is the most reactive?
Potassium
Lithium
Sodium
Rubidium
Answer: Option (d) is the correct answer.
Explanation:
It is known that reactivity of atoms increases on moving down the group. This is because on moving down the group there is also increase in number of shells.
As a result, outer shell electrons move away from the nucleus and thus force of attraction between the nucleus and electrons decreases.
Hence, it is easy to remove the electrons from outermost shell and thus reactivity of atom increases.
Therefore, we can conclude that the given elements are group 1 elements and largest of them is rubidium. Thus, out of the given options, rubidium element is the most reactive.
The most reactive element among the options provided is potassium, the correct option is (a).
Potassium is the most reactive due to its lower position in Group 1 of the periodic table. Reactivity in alkali metals increases down the group because the outermost electron is further away from the nucleus, making it easier to lose and engage in chemical reactions.
As a result, potassium readily reacts with water and oxygen, vigorously producing hydrogen gas and metal oxides. Due to its high reactivity, potassium is stored in mineral oil to prevent rapid oxidation. Additionally, its reactivity is harnessed in various industrial and laboratory processes, the correct option is (a).

The thresher and irrigation practices were two innovations that were created during the first agricultural _____ from 1862 to 1875.
Answer:
revolution.
Explanation:
Final answer:
The thresher and irrigation practices are innovations of the first agricultural revolution from 1862 to 1875, part of the broader Industrial Revolution that introduced significant changes in agriculture, including the use of gasoline-powered farm tools.
Explanation:
The thresher and irrigation practices were two innovations that were created during the first agricultural revolution from 1862 to 1875. This period, which overlapped with the Industrial Revolution, brought about a significant change in agricultural practices. Innovations such as gasoline-powered farm tools, including tractors, seed drills, threshers, and combine harvesters, revolutionized farming. These advancements allowed farmers to cultivate larger fields with a single crop, increasing their efficiency and productivity.
Such changes also followed earlier agricultural improvements, dating back to the introduction of basic tools around 2500 B.C., and continued advancements such as the introduction of fertilizers and three-field crop rotation techniques in the middle ages. The influence of technological innovation in agriculture eventually led to an increased capacity to satisfy the growing food demands of rising populations.
Inventions such as the seed plough by Jethro Tull and the concept of crop rotation by Charles Townsend in the 18th century paved the way for these significant shifts. The idea was to maximize productivity and cope with the ongoing demands of population growth. These innovations also supported America's rise as a major food exporter during World War I and the 1920s. Machine-powered irrigation systems further underscored the mechanization of agriculture, enabling farmers to cultivate larger areas and enhancing the reliability and quality of crop production.
