Answer:
True
Explanation:
Isotopes of uranium, specifically uranium-235 and uranium-238, are commonly used as nuclear fuel in power plants. When these isotopes undergo nuclear reactions, they release large amounts of energy, which can be used to generate electricity.
b. climax communities are not possible
c. dominant organisms drive out pioneer species
d. ecosystems never reach a sustainable point
Correct answer: A) Organisms gradually change the environment
Succession occurs when there is a disturbance in the environment, it would be a minor disturbance like a fire or a major disturbance like a volcanic eruption. Based on the disturbance, succession can be divided into two types:
1). Primary Succession: Primary succession is said to happen when a group of the species or a community evolve from a barren land or a land with no life. This land is fresh and does not have any life on it.
Example: Primary succession occurs after a volcanic eruption
2). Secondary Succession: The secondary succession is said to occur when there is a disturbance and it destroys ecosystem but still there is an availability of nutrient, seed, and soil.
Example: Forest Fire
Succession occurs because organisms gradually change the environment. (Option a.)
Succession is the process by which an ecosystem undergoes changes over time due to the influence of living organisms. It occurs because organisms gradually change the environment they inhabit. In ecological succession, there are two main types:
1. Primary Succession: This occurs in areas where no previous ecosystem existed, such as bare rock, volcanic lava, or newly formed sand dunes. Pioneer species, like lichens and mosses, are the first to colonize such areas. Over time, they break down the rock and create soil, making it possible for other plants and organisms to establish themselves. As the environment changes and becomes more hospitable, the community of species gradually changes, leading to a series of distinct stages until a stable climax community is reached.
2. Secondary Succession: This type of succession occurs in areas that have been disturbed or disrupted, but where soil and some remnants of the previous ecosystem remain. For example, after a forest fire or clear-cutting, the area will undergo secondary succession. Pioneer species, often grasses and shrubs, quickly establish themselves and create conditions for other species to colonize the area. As the ecosystem recovers, different stages of plant and animal communities succeed one another, eventually leading to a climax community that is relatively stable.
In both types of succession, organisms play a significant role in changing the environment, creating conditions that allow new species to establish and eventually leading to a more complex and diverse ecosystem.

Answer:
Formula for sulfuric acid is H2SO4
Explanation:
Sulfuric acid is highly concentrated acid. It is known as king of chemicals. It is used in making of fertilizers, paints, dyes, detergents, etc.
H2SO4 is made in laboratory in different steps from burning of sulfur and oxygen. The sulfur is burned with air and oxygen is combined with it to form sulfur dioxide ( SO2).
Then SO2 is again mixed with oxygen in the presence of catalyst vanadium. It forms sulfur trioxide ( SO3). The sulfur trioxide is allowed to absorbed in water. The mixing of SO3 and H2O forms the sulfuric acid ( H2SO4).
It is highly concentrated and its dilution is decreased to some extent for selling.
