How would knowledge of North Pacific Ocean food webs help scientists understand what was happening to organisms during the algae bloom in 2015
Knowledge of North Pacific Ocean food webs would help scientists understand the algae bloom in 2015 by providing insight into the complex interactions between different species in the region.
How did knowledge of North Pacific Ocean food webs help scientists understand the algae bloom in 2015?During an algae bloom, the rapid growth and reproduction of algae can cause changes in the food web. For example, the increase in algae can lead to an increase in zooplankton populations that feed on them, which in turn can lead to an increase in populations of larger organisms that feed on the zooplankton. However, the effects of the algae bloom can vary depending on the specific species involved and their roles in the food web.
By understanding the North Pacific Ocean food webs, scientists can identify which species are most likely to be affected by the algae bloom and how their populations may be impacted. For example, some species may benefit from the increase in food availability, while others may be negatively affected due to changes in the availability of their own food sources.
Moreover, studying food webs can help to identify potential cascading effects of an algae bloom on other components of the ecosystem. For example, changes in the abundance of a predator species can impact the abundance of its prey, which can in turn impact the abundance of other species in the food web.

In a paragraph, explain how a virus replicates and why diseases caused by viruses are harder to treat than bacterial infections. Be sure to use specific examples.
Answer:
Viruses cannot replicate on their own, but rather depend on their host cell's protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles
Many human illnesses are caused by infection with either bacteria or viruses. Most bacterial diseases can be treated with antibiotics, although antibiotic-resistant strains are starting to emerge. Viruses pose a challenge to the body's immune system because they hide inside cell

Explanation:
Suppose that humans introduced rabbits into an area where rabbits have no natural predators which best predicts what would happen
If humans introduced rabbits into an area where there are no natural predators, the rabbit population is likely to increase significantly. Without any natural predators to limit their population growth, rabbits would have access to abundant resources and be able to reproduce rapidly.
Over time, the rabbits could become overpopulated and start to damage the local ecosystem by consuming all of the available vegetation. This, in turn, could lead to a decline in biodiversity and negatively impact other animal species in the area.
The situation is not unique, and it has been observed that the introduction of non-native species into an ecosystem can have serious ecological and economic consequences.
For example, the introduction of rabbits into Australia by British settlers in the 19th century resulted in a significant environmental and economic impact, including the loss of millions of dollars in agricultural crops.
Therefore, it is essential to carefully consider the potential ecological consequences of introducing a non-native species into an ecosystem before doing so.

45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?
Answer:
Explanation:
Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.
The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.
The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.

what are two reasons for constancy in growth and development
Constancy in growth and development refers to the relative stability or balance of growth and development processes in an organism over time. There are several reasons why constancy is important for proper growth and development.
Stability in the environment: Changes in the environment can cause major disruptions in an organism's growth and development. Consistency in growth and development helps organisms maintain their internal stability and adapt to environmental changes without being negatively impacted by them. Efficient use of resources: Consistency in growth and development ensures that organisms use their resources efficiently and effectively. This means that they are able to allocate resources to various systems and processes without wasting resources or overtaxing particular systems or processes. By doing so, organisms are better able to maintain constancy in their growth and development over time.
