The mitochondrion!!! Of course!!
Answer:
If the string of beads refer to a chromosome, then each bead is a gene responsible for one or more traits.
If the string of beads refer to a gene, then each bead refers to the sequence of nitrogenous bases in one strand of the gene.
Explanation:
A chromosome is composed of several genes.
A gene is composed of several nucleotides each containing a nitrogenous base. A gene is primarily made functional by the sequence of nitrogenous bases in its structure. If AGATTCA is a hypothetical sequence of the nitrogenous bases on one strand of a hypothetical gene then TCTAAGT will be the sequence of nitrogenous bases on the complementary strand of that particular gene.
Perhaps your question regards producents, consuments and reducents.
Producents produce organic compounds (from inorganic minerals in the environment most likely via photosynthesis, i.e. plants and photosynthetic bacteria)
Consumers consume organic compounds (from other living organims by devouring them, i.e. herbivorous and carnivorous animals)
Reducents reduce organic compounds (into inorganic minerals from other living and dead organisms, i.e. saprophytic bacteria and fungi)
The three components combined together stabilize the circle of matter in the ecoystem: inorganic compound is used to make organics, which then is transformed back into inorganics over and over and over again.
True it does cause the temperature of that system to increase
I believe the correct answer from the choices listed above is option 2. Abandoned farmland that once grew corn is now covered with bushes and small trees. These observed changes resulted directly from ecological succession. It <span> is the process of change in the species structure of an </span>ecological<span> community over time. </span>
