The overall health of the scrub (shrubland) biome can vary depending on various factors, including climate, human activities, and ecological disturbances.

Negative impacts on the biome can lead to other problems such as habitat loss, species extinction, and decreased ecosystem resilience.

For instance, deforestation or land conversion for agriculture or urbanization can fragment the scrubland habitat, disrupt wildlife populations, and reduce overall biodiversity.

Additionally, pollution from industrial activities or improper waste disposal can contaminate the soil and water, affecting the health of plants, animals, and microorganisms in the ecosystem.

To reduce these negative effects and promote a healthier scrub biome, several approaches can be taken. Firstly, implementing sustainable land management practices is crucial.

This includes responsible land-use planning, reforestation efforts, and promoting conservation strategies to protect existing scrubland areas. By preserving and restoring the natural habitat, we can help maintain the balance of the ecosystem and support the survival of native species.

Secondly, promoting awareness and education about the importance of the scrub biome is essential.

By educating communities, policymakers, and landowners about the value of these ecosystems, we can foster a sense of stewardship and encourage environmentally friendly practices.

Lastly, adopting sustainable agricultural practices can contribute to the health of the scrub biome. Implementing techniques such as agroforestry, organic farming, and precision agriculture can minimize the use of harmful chemicals, reduce soil erosion, and promote biodiversity on agricultural lands adjacent to scrubland areas.

Overall, protecting and restoring the health of the scrub biome requires a multi-faceted approach involving conservation, education, and sustainable practices to mitigate negative impacts and preserve the unique characteristics and ecological functions of this important ecosystem.

Answer:

The answer to this question is Transport would increase.

Explanation:

The transport would just increase.

In the given area-to-volume ratio, the transport would increase across the cell membrane. The correct option is B.

The surface area to volume ratio is merely the surface area divided by the volume of an entity. It calculates the surface area per unit volume of the object.

The crucial fact is that as the cell size increases, the surface to volume ratio decreases.

If the cell expands beyond a certain size, not really enough material can cross the membrane quickly enough to cater the increased cellular volume.

The surface area divided by the volume is the ratio. This suggests how much surface area is accessible in relation to the size of the cell.

The cell is very large if the surface area to volume ratio is small. If the ratio is large, the surface area exceeds the volume the cell will be small.

Thus, the correct option is B.

The ecology of a lake obtains considerable damage when items are put in it that aren’t supposed to be there. Human activities like agricultural runoff, dumping of industrial waste, and sewage treatment contribute to the pollution of freshwater bodies. It affects aquatic life and the ecological balance of the lake by disrupting the food chain and natural processes.

An ecosystem refers to a natural system of living things and their surroundings. A lake ecosystem includes various living organisms such as fish, plankton, algae, and many other aquatic species. Additionally, it comprises non-living things such as water, minerals, nutrients, etc. Any human-made or synthetic material that enters the lake upsets this natural balance. When harmful chemicals such as pesticides and fertilizers are used on agricultural fields, they contaminate the water and increase the nutrient content of the lake.

It encourages the growth of algae and other aquatic plants that use up oxygen in the water. When they decompose, they further reduce oxygen levels, which results in suffocation and death of aquatic organisms.Dumping of industrial waste is another human activity that contributes to the pollution of freshwater bodies. Chemicals like lead, mercury, and arsenic are toxic and can cause severe damage to the aquatic ecosystem. Fish and other aquatic animals may ingest these toxins and can accumulate them in their body tissues.

It results in reduced growth, deformities, and death of these animals. Sewage treatment is essential in cities to ensure that wastewater is treated and released into natural water bodies. However, inadequate or improper treatment can lead to a considerable increase in nutrients and organic matter in the lake, leading to harmful algal blooms and fish kills. In conclusion, human activities have significantly damaged freshwater ecosystems, and steps must be taken to reduce pollution to save these vital resources.
