Answer:
The answer is C.
A 5 percent increase in the reproductive success of some genotypes, but a 5 percent decrease in the reproductive success of other genotypes
Explanation:
Incomplete question, here is the full question: https://quizlet.com/153540854/biology-107-part1-flash-cards/
For the genetic structure of a population to change, we can either depend on natural selection or mutations but there has to be an imbalance.
The answers given in the options A and B are referring to changes in genotypes which surely affects the genetic structure of the population but the way these options are given is in equilibrium, meaning they create and imbalance but then counter that with something else.
In option C, some genotypes get a 5 percent increase while some get a 5 percent decrease in their reproductive success, which will most likely result in a change in the genetic structure of a population.
I hope this answer helps.
Answer: b. Increased nutrient run-off
Explanation:
Nutrient run-off is when an excessive amount of nutrients like Nitrogen and Phosphorous find themselves in bodies of water. This acts as a fertlizers and promotes algae growth.
This algae growth compromises the qualiy of water and depletes the oxygen in the water. This essenfially harms the habitat thus this is noy an ecological benefit.
Answer:
B
Explanation:
When humans dig-up fossil fuels and burn them to power the modern world, <u>carbon flows between the Geosphere/lithosphere and the atmosphere.</u>
Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.
<em>Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.</em>
The correct option is B.
Plants absorb me from the soil through assimilation, I am eaten by animals the animals and plants die and decompose where I am released back into the soil, weathering and erosion cause me to release out of rocks, I then find my way into the ocean being carried by water, I then return to the soil through the water.
