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.

The answer is D: of the above
Answer: A trait that is affected by many factors, both genetic and environmental, that enhance, halt, shape, or alter the expression of genes, resulting in a phenotype that may differ markedly from the genotype, is said to be MULTIFACTORIAL.
Explanation: Multifactorial inheritance may be presented by a model in which liability to a disorder is dependent on combination of genetic factor and environmental factor. Examples of trait with this mode of inheritance are neural tube defects, cleft lip and congenital dislocation of the hip.
The answer would be:
Arthropods
Here's more about Arthropods:
Arthropods basically share a simple body plan, even if they make up the largest phylum of kingdom animalia. Their known characteristics are <u>jointed appendages</u> and <u>exoskeleton. </u>
<u></u>
The exoskeleton of arthropods are mostly made up of chitin and they are stiff. This external skeleton provides arthropods with protection, but they do not grow. So periodically, they shed or molt, so it can grow. After it molts, it secretes a new exoskeleton and it eventually hardens.
