Answer:
If the carrying capacity of the goldfish pond is reduced from 125 to 90, then the pond can sustain a fish population of 90 or fewer, specifically allowing for populations of 90, 75, and 50 goldfish.
Explanation:
The choices provided in the question include:
- The pond can support 125 goldfish.
- The pond can support 110 goldfish.
- The pond can support 90 goldfish.
- The pond can support 75 goldfish.
- The pond can support 50 goldfish.
In population dynamics, the carrying capacity is defined as the upper limit on the number of individuals able to inhabit a specified area based on available resources like food, space, and water, pertinent to ecosystems as well.
A decline in the carrying capacity to 90 goldfish indicates that the resources can only sustain a population that is equal to or less than 90; thus, it can be stated that:
- The pond can support a fish population of 90.
- The pond can support a fish population of 75.
- The pond can support a fish population of 50.
When a species exceeds its carrying capacity, mortality rates typically rise.

D because they share the same materials but have different structures which results in different functions
Conducting experiments in a lab involves operating in a controlled setting. If the populations of birds in generation 1 and generation 3 fluctuate, potential reasons could include: - Changes in the availability of food - If a flock's beak type facilitates food gathering, that flock might thrive, and the opposite could lead to a decline. Justification: If generation 1 has a beak type that aids in food intake, it will expand, potentially diminishing food resources for generation 3, which may feature a less advantageous beak type.
Answer:
The body combats the virus, and upon its return, it can recognize and eliminate it. However, during this process, we rely on antibodies and other mechanisms to fight off the virus, which explains the weakness felt in that period. It may take time to completely eradicate the virus.
This explains the conclusion.
Explanation:
Answer: Amylase
Explanation: it’s an enzyme found in saliva that facilitates the breakdown of starches, such as those present in pasta, aiding in food digestion.
