A laboratory investigation examined the growth rate of fruit flies in culture jars over time. The fruit flies were grown in an artificial medium containing nutrients and moisture. They were enclosed in a culture jar of a defined size. Initially, there were ten fruit flies
in the experiment. The population reached 75 over the course of four weeks. However, after eight weeks, the population size
leveled off and then decreased. Survival of fruit fly larvae declined after eight weeks. Which hypotheses are supported by the
information in this scenario? Select ALL that apply?

A)
The older fruit flies were unable to reproduce
Scientific
Calc
B)
The carrying capacity was exceeded by the fly population
Food was abundant for the first four weeks of the experiment.
D)
The fruit flies were unable to survive in a laboratory setting
E)
The carrying capacity decreased when no new food was added to the
culture jars.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
