According to endosymbiotic theory, the chloroplast evolved as a result of engulfment and assimilation of a Cyanobacteria by an eukaryotic cell.
Explanation:
- Endosymbiotic theory supports the view that ceratain organelles of the eukaryotic cell evolved as a result of engulfment of single celled organism.
- Evidences that support this theory is the presence of organellar DNA.
- It is assumed that Mitochondria evolved as a result of engulfment and assimilation of an aerobic prokaryote while Chloroplast evolved due to engulfment and assimilation of a photosythetic prokaryote by an Eukaryote.
- After the engulfment ,these organisms however escaped the phagocytosis and began to benefit the eukaryotic Host.
- Soon it lost many of its Genes to the eukaryotic nucleus and became dependent on the Host.
- Thus a symbiotic association was established between the prokaryote and the host.Giving rise to cell organelles.
Answer:
<em> The carrying capacity is determined only by the density-dependent factors.</em>
Explanation:
The maximum number of organisms of a particular species that an environment can hold is known as the carrying capacity of that environment. The carrying capacity depends on density-dependent factors as well as density- independent factors like weather, sunlight etc.
Beyond the carrying capacity, the organisms will begin to fight with each other for limited resources. The environment will become unstable as the resources will be scarce and individuals will be more.
Scientific inquiry process discusses to the varied means in which scientists study the natural world and suggest clarifications founded on the evidence derived from their work. Since there are many different kinds of problems that science can address, and the "scientific method" that's taught in class isn't appropriate for every type of investigation because different questions may require different approaches to finding answers. That’s why scientists custom-build the procedures (like a process with many parts) they will use depending on the unique challenges of the problem they are trying to solve.
