Answer:
(c) directional selection
Explanation:
Directional selection is a type of natural selection that occurs when members of a population of a species with a particular extreme phenotype is selected or favored against the other phenotypes when natural forces act on the population of a species. Individuals having the particular traits that are favored survive and become more common that others with traits that are less favored.
Directional selection may likely result in the species of butterflies in which darkly collared butterflies are not preyed upon, ensuring their survival, while the other butterflies with other colors will be phased out with time. Darkly colored butterfly will be selected for while the others will be selected against.
<span>(I got this from my handbook dictionary)
"the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes."
What that basically means is that homeostasis is the ability to respond to certain environments. It is how you respond to environmental changes and how you basically adapt to it.. that's where the idea of response and adaption came from.
Hope this Helps!! (I had a quiz on this once) </span>
The complex of DNA and protein that makes up a eukaryotic chromosome is properly called <u>chromatin .</u>
<u></u>
- Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
What is the chromatin and its function?
- To create chromosomes, chromatin fibers are coiling and condensing.
- Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.
What is chromatin in cell?
- Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins.
- Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands.
Where is chromatin found?
- Chromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell.
- This chromatin is located within the cell nucleus.
