(b) Define ecosystem, biome, ecological community. (c) What is the benefit of learning ecology? What is deep and shallow ecology? What is ecology, and what are the components of it that are usually studied in biology? What is the eco-niche that Homo erectus first adapted to?
What is a realized niche? Explain the difference between a fundamental niche and a realized niche. What are the three factors a niche includes? What is an intrinsic factor? Explain the Niche Overlap Hypothesis. Explain in what way the realized niche could be regarded as flexible. Compare and ...
There are two different descriptions of a species' niche, the fundamental and the realized. These can be thought of as the "potential" and "realistic" niches. The fundamental niche of a species includes all of the conditions in which it could live, all of the geographic regions it could ...
Much effort is being invested in defining the intrinsic and extrinsic factors that control stem cell maintenance and proliferation. Recent studies have identified a signaling hierarchy involved in coordinating the proliferation of germ line and somatic stem cells in the Drosophila ovary. DOI: 10.1016/s...
The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specia
What Is a Biomedical Engineering Major? Students who study biomedical engineering learn to pair biology with engineering to design medical devices and therapies. These students plan experiments, analyze and interpret data, and use engineering principles to judge the results of their work. Biomedical eng...
She specialized in a niche branch of molecular biology. 7 Limb A crucial part or member of a group. As the lead guitarist, she was a vital limb of the band. 7 Branch A branch (UK: or UK: , US: ) or tree branch (sometimes referred to in botany as a ramus) is a woody structura...
If just one step in a pathway gets altered, it can lead to a domino effect. But through the advances in science, health care can help bring that person to baseline. It is one thing to learn about these advances in lectures, but it is monumental to see their effects in person, like ...
Expertise refers to a person's depth of knowledge or skill in a particular area, while specialty is a focused field within a broader domain where one has significant expertise.
How does the difference between a fundamental and a realized niche relate to evolution? Explain why natural selection is the only evolutionary mechanism that consistently leads to adaptive evolution. What are the main principles of natural selection?
