Important erosion, rapture, and removal of solids happen through storms. Beach erosion is a typical consequence of the high waves that transpire when hurricanes pass onto land. The decline of sand makes the beach to grow narrower and deeper in elevation. Storm loops take the sand offshore, keeping and depositing the sediment in great sandbars.
Answer: d. Erosion caused by hurricanes can leave coasts more exposed to storms
Explanation:
Hurricanes are the storms which forms over the warm oceans due to high speed wind currents that blows over the land. The potential threats associated with the hurricanes will include the heavy rainfall, tornadoes and landslides. It will cause major erosion of the landforms making them fragile and weak and susceptible to damage when exposed to further storms.
The replacement of one variant or strain of bacteria with another is primarily driven by selective pressures in the environment.
Bacterial populations are dynamic and can undergo changes in composition over time. The replacement of one bacterial variant or strain with another can be attributed to various factors, but one of the key drivers is selective pressures in the environment.
Selective pressures refer to the conditions or factors in an environment that favor the survival and reproduction of certain bacterial variants over others. These pressures can include factors such as changes in nutrient availability, pH, temperature, antibiotics, competition with other microorganisms, and interactions with host organisms. Bacterial variants that possess adaptations or traits that are better suited to the current environmental conditions will have a higher fitness and are more likely to thrive and reproduce. Over time, this can lead to the replacement of less fit variants with those that are better adapted to the prevailing selective pressures.
The process of replacement can involve natural selection, where the genetic diversity of bacterial populations allows for the emergence of advantageous traits through mutation and genetic recombination. The dynamics of bacterial replacement are central to understanding microbial evolution, the development of antibiotic resistance, and the interactions between bacteria and their environments.

The replacement of one variant/strain of bacteria with another is primarily driven by competitive advantages in adaptation and resource utilization.
This phenomenon, often observed in microbial communities, results from the intricate interplay between bacterial populations and their environment. Bacteria are remarkably adaptable and can rapidly evolve to exploit specific ecological niches. When a particular variant or strain gains a competitive edge in utilizing available resources or tolerating environmental conditions, it can outcompete its counterparts, leading to the replacement of the less adapted strains.
Bacteria's ability to undergo genetic mutations and horizontal gene transfer contributes significantly to their adaptability. Variants with mutations that confer advantages such as increased nutrient uptake or resistance to stressors tend to thrive in their environment. As these advantageous traits are passed on to subsequent generations, the dominant strain becomes better suited to its niche, gradually replacing less fit strains.
Furthermore, changes in the environment, such as alterations in nutrient availability or temperature shifts, can create conditions that favor specific bacterial variants. These environmental shifts can act as selective pressures, favoring the proliferation of strains better equipped to handle the new conditions.
In microbial ecosystems, the replacement of bacterial strains is a dynamic process shaped by a complex interplay of genetic, environmental, and competitive factors. Understanding these dynamics is crucial not only for grasping microbial ecology but also for applications in fields such as biotechnology, medicine, and environmental management.

Where is Glycolysis happening
Answer:
Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
