Answer: c. high-level waste
Explanation:
The used or spent fuel comes from the nuclear reactor that can be no longer efficient to be used again for the purpose of generating electricity, because the efficiency to conduct fission reaction by such fuel is low. But still it may be thermally hot, highly radioactive and harmful. It comes under the category of high level wastes. The high level wastes are those wastes that are produced as a byproduct of the nuclear reactors.

Answer:
The root of a huge tree causes cracks in a rocky surface.---> biological Weathering.
Part of a cliff breaks and falls due to waves.----> mechanical weathering
Acid rain reacts with calcite present in limestone---> chemical weathering
Explanation:
The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved. Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands. Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.
Here's the matching of the scenarios with the types of weathering:
1. The root of a huge tree causes cracks in a rocky surface - Biological Weathering
2. Part of a cliff breaks and falls due to waves - Mechanical Weathering
3. Acid rain reacts with calcite present in limestone - Chemical Weathering
Biological Weathering: In this scenario, the root of a huge tree causes cracks in a rocky surface. Biological weathering refers to the breakdown of rocks caused by the activities of living organisms. The roots of the tree can exert pressure on the rocky surface as they grow, causing cracks and eventually breaking apart the rock.
Mechanical Weathering: Part of a cliff breaks and falls due to waves. Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. In this case, the force of the waves pounding against the cliff causes pieces of the rock to break off and fall.
Chemical Weathering: Acid rain reacts with calcite present in limestone. Chemical weathering involves the breakdown of rocks through chemical reactions. Acid rain, which is rainwater with a low pH due to the presence of acidic compounds, reacts with the calcite (a mineral in limestone) and causes it to dissolve, leading to the erosion and weakening of the limestone.
Each type of weathering plays a role in shaping the Earth's surface over time, and they often work together to break down rocks and minerals into smaller particles.

Answer:
A bright light close to the plant.
Explanation
Plants grown in bright light had higher rates of apparent photosynthesis per unit leaf area in bright light, and slightly lower rates in dim light than did those of plants grown in dim light. Dark respiration rates were higher in plants grown in bright light than in plants grown in dim light and the decline of photosynthesis with increasing leaf age was faster.
The rate of apparent photosynthesis in bright light of the first leaf to become fully expanded after plants were transferred from bright to dim light was lower than that of plants remaining in bright light. The decline in the rate of photosynthesis of a leaf already fully expanded at the time of transfer was not affected. Transferring from dim to bright light increased the rate of photosynthesis of the next expanded leaf; it also increased the rate of an already fully expanded leaf during the first week in bright light.
homeostasis
immunity
response to stimuli
reproduction
growth and development
The correct answers are -
b) Homeostasis
c) Immunity
e) reproduction
f) growth and development
Reason -
The endocrine system (produces and secretes hormones) is a vital system as it regulates the homeostasis by regulating the cell activity in the body. The endocrine system releases relevant hormones during specific time period in the blood which are then transported across the blood , this not only maintains the chemical physical balance in our body but also regulate the vital functions of body such as growth, reproduction, and immunity
hydro may produce asexually.
The right answer is enzymes (catalase).
Catalase is an enzyme that allows the dismutation of hydrogen peroxide (hydrogen peroxide) in water and oxygen.
The oxygen-oxygen bond of the hydrogen peroxide is cut off by the iron atom of the heme group, creating a molecule of water and a highly oxidizing iron-oxygen bond. This can oxidize a new molecule of hydrogen peroxide, giving oxygen. The enzymatic reaction at play is one of the fastest known.
Within the cell, catalase helps protect the body from the oxidative and harmful action of hydrogen peroxide.
