Answer:
E) ecological niche
Explanation:
Every species on the planet, be it a bacteria, animal, or a plant has its own ecological niche. Basically, the ecological niche is the position and role that an organism is occupying in the environment. Further, this means that it is a combination of all the activities of the organism, how it uses the biotic and abiotic factors in the environment it leaves, how it finds food and how it feeds, its shelter, reproduction, the manner in which it survives. All of that sums up the species and its role in the environment, thus its ecological niche. There are countless ecological niches, as there are millions of different species, all of which have their own way of living, feeding, reproducing, interactions with the biotic and abiotic factors, resulting in numerous unique ecological niches.
Answer:
Major difference between active transport and facilitated difusion is:
Active transport moves substances against the concentration gradient.
Facilitated diffusion moves molecules through the plasma membrane.
Explanation:
- Active transport involves the transport of molecules against the concentration gradient.
- Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
- Facilitated diffusion do not require energy but need some other molecule or carrier protein to transport the molecules across the membranes.
- In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.
Answer:
When an electron absorbs energy, it jumps to a higher orbital. An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy.
Explanation:
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock.
