The action that may increase the flask's carrying capacity for rotifers would be to decrease the number of microorganisms in the flask.
<h3>Carrying capacity</h3>
The carrying capacity of an environment refers to the maximum number of organisms of a particular species that the environment can support based on the resources it has.
Rotifers and microbes growing in the flask mean that both species would have to compete for the resources present in the flask. This competition will limit the reproductive capacity of each species.
As the population of the species decreases, the growth of the other is favored due to less competition.
With rotifers growing alone in the flask, there would be less competition for resources and more population growth.

Answer:
Option (A) and (C).
Explanation:
Global warming may be defined as the increase in the average earth's temperature. The global warming occurs due to human activities like deforestation and urbanization.
The green houses gases are responsible for increase in the global warming. Gases like water vapor, methane and carbon dioxide can trap the heat and causes global warming. The green house effect is directly proportional to the amount of green house gasses as more heat are trapped by green house gases.
Thus, the correct answer is option (A) and (C).
Phloem is the tissue in the plant system that transports the nutrition and the food materials to the plant parts. It is composed of many specialized cells like fibres, parenchyma cells, companion cells and sieve tubes.
Phloem's end walls have openings that let water and nutrients pass through them.
<h3>How does the structure of phloem help in transportation?</h3>
- The tissue of the transporting system has small openings at their end sections that allow the passage of the food and water up and down the vessels of the plant.
- The tiny holes present for the exchange of gases and water are called stomata while the root hair changes its shape to absorb water from the soil.
Therefore, option A is correct.

Answer:
fish and tetrapods are both vertebrates that have a backbone with a spinal cord. fish lived before tetrapods because their fossils are in rocks over 500 million years old.
