e2020 :) Good luck! <3
The correct pairing of human activity with the greenhouse gas it increases is: Deforestation and methane.
What is deforestation?Deforestation refers to the deliberate or widespread removal of trees and vegetation from forests or woodland areas, leading to the conversion of forested land into non-forest uses. It involves the permanent destruction or clearance of forests, typically for purposes such as agriculture, logging, urbanization, or infrastructure development.
Deforestation has significant environmental, social, and economic implications. It contributes to habitat loss, biodiversity decline, soil erosion, and climate change. Forests play a crucial role in carbon sequestration, regulating the water cycle, and providing habitats for countless species.
Deforestation disrupts these ecological processes and can lead to the loss of invaluable ecosystem services. Efforts to combat deforestation involve sustainable land management, reforestation initiatives, and the promotion of responsible forestry practices.

The oak and the maple are two different species of trees that also belong to different genera. However, these oak and maples do share many characteristics. Based on their similarities, which levels of classification would they share?
Answers
Answer:
Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other. The same is true for maple

why do lichens and mosses get mostly replaced by larger plant species during succession
Answers
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

FIRST PERSON TO ANSWER GETS BRANLYSEST After Hunter drank a glass of milk, sugar levels in his blood increased. This stimulated the hormone insulin to be released. Insulin helped the sugar move from his blood into cells, so his blood sugar levels decreased. Which statement explains what happened next? Positive feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to produce more insulin. Positive feedback caused his pancreas to produce more insulin.
Answers
Answer:
The correct answer B
When the body gets the glucose, the glucose in the blood increase then the hormone insulin is released so that the glucose from the blood can be transferred from blood into the cells of the body.
The release of hormone insulin is a positive feedback.
Once the glucose is transferred into the cells of the body then the negative feedback starts acting that stops the secretion of insulin from the pancreas.
What will happen next is that negative feedback would cause his pancreas to stop secreting insulin.
The maintenance of relatively constant internal body processes depends largely on negative feedback.
Negative feedback mechanisms ensure that setpoints are returned.
Hence, whatever causes setpoints to be breached is reversed or removed totally.
In this case, the continuous secretion of insulin will further lower the blood sugar level and causes the setpoint to be breached further. Thus, the actuator (insulin) has to be removed.
