<h2>Ecological species concept</h2>
Explanation:
Ecological species concept is the concept of species where species is a group of organisms adapted to specific resources,called niche in the environment
- Every species has a different niche;niche is simply the role played by the organisms in a particular area(environment) in which it is living
- Ecological and evolutionary processes controls the resources and divides the species into groups
- In the given example members of one population of wolf spiders are found in leaf litter within the woods while the other one is found in the grass at the edge of the woods
- Both the members are distanced from each other ecologically and their role to use resources changes
- Hence they are designated as two different species by utilizing the ecological species concept

I think it is c but I hope it can help.
Calcium ions are stored in the sacoplasmic reticulum. Sarcoplasmic reticulum plays an important role in storage and also acts as a release site for calcium. When calcium is released by the sarcoplasmic reticulum into the muscle it binds to the troponin, thus causing the tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce a contraction.
Answer: 2.35 x 10^6 cfu/ml
Explanation:
Concentration of the original culture: ?
Dilution factor: 10^4
Colony count per plate: 47cfu
Volume of cultured plate: 0.2ml
Concentration of the original culture= <u>Colony count per plate x Dilution factor</u>
Volume of cultured plate
Concentration of the original culture = <u>47 x 10^4 </u>
0.2
Concentration of the original culture = 2.35 x 10^6 cfu/ml
You can further take the log of your answer which would be:
Log(2.35 x 10^6) = 6.371
