In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
<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
At pH 7, this enzyme's maximal initial reaction rate is 350 X 10>6 per minute of product produced with a saturation of 2–4g of substrate.
- An enzyme-catalyzed reaction has a very productive relationship between the substrate concentration and the starting reaction, but the pH of the supplied solution has a significant impact on this relationship. pH7 has the highest rate of productivity.
- The connection is roughly linear with respect to substrate concentration and pH level up to the saturation point, which in this case was attained between 2g and 4g of substrate.
- Up until the point of saturation, which in this instance is between 2g and 4g of substrate, the reaction is more productive with increasing concentration. Beyond that point, adding more substrate has no extra benefit.
