ANSWER:
After the volcanic eruption,lava cools down,vegetation reappears and microscopic plants grow,then the macroscopic plants and animals come at that place,then gradually the whole system builds and ecosystem recovers.
EXPLANATION:
Biodiversity means diverse population of plants and animals. After the volcanic eruption,both plants and animals donot exist because of high temperature and not suitable environment. With the passage of the time, the lava cools down and vegetation stars reappearing. First of all lichens and microscopic plants and after that macroscopic plants and animals come at that place.Thus suitable conditions reappear and gradually the whole ecosystem recovers.
Answer:
(A) Organisms within a population compete with each other to survive.
Explanation:
The male oryx are fighting with their horns to probably compete with each other for maybe who gets to graze in a certain part of the forest or gets to mate with a female.
Answer:
When carbon dioxide is released into the environment, typically due to human activities and respiration in animals, it gets trapped in the atmosphere. Carbon dioxide is just one greenhouse gas, but as all of the gases accumulate in the Earth, the temperature begins to rise globally. There are many implications to this, including the melting of glaciers, bleaching of corals, and increasing necessity for air conditioning systems and ventilation. When glaciers melt, they become a part of the ocean, meaning that as more glaciers begin to thaw out, the ocean will being to grow up and out. As sea levels rise, humans and animals are left with no choice but to being moving to higher points of elevation to avoid sinking. Another consequence of glacial melting is the loss of habitat for animales in many environments. Those living in glacial areas will begin to lose the snow and ice they are built to withstand. Those living near the sea or at low points of elevation will lose their habitats as it sinks deeper into the ocean. Another problem with global warming is coral bleaching. As the ocean warms up from the rising temperature, corals will being to overheat until they become ”blaeched’ whihc essentially means that they die. Lastly, global warming will create an increasing necessity for air conditioning systems and ventilators. People who do not have access to these things or cannot afford them can risk health complications. Global warming is a problem that cannot be ignore and the world needs to take more steps to plant trees and grasses that can photosynthesize the carbon dioxide into oxygen.
Answer: Transcription factors
Explanation:
The dioxin enters the blood stream and the fat cells and liver cells store it.
While moving inside the cell the dioxin binds to the protein called Aryl hydrocarbon which then binds to the second receptor.
The complex is then carried to the nucleus of the cell. This tends to on and off certain genes.
This turning on and off of the genes in the cell can lead to serious diseases like cancer, decreased immune function, et cetera.
