Hi !
Here is your answer !
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.
Explanation:
The gas responsible for the most warming is carbon dioxide, or CO2.
Thank You !
Here is how to solve... answer should be x = -1. Hope this helps!
Answer: Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.
Explanation:
Answer: Massive star supernovae
2. Can only occur in a galaxy with ongoing star formation.
3. Black hole or neutron star left behind.
White dwarf supernovae
1. Star explodes completely, leaving no compact object behind.
4. Can only occur in a binary system.
5. Can occur in a very old star cluster.
6. Spectra always lack strong hydrogen lines.
7. Has a brighter peak luminosity.
Explanation: A supernova is a bright explosion of a star as it dies off. Supernova can occur due to the star losing the heat at its core which eventually makes it collapse. This is the type of supernova formed when massive stars die. They occur in a galaxy with ongoing star formation and a black hole or neutron star left behind.
Supernovae can also be occur when a star orbits another and crashes into another. This is what occurs in a white dwarf
. This is part of a binary system, can occur in a very old star cluster and leaves no compact object behind.
Answer:
Rubber tree, oak, spruce, pine are some examples of trees that are commonly cut down
Explanation:
The cutting down of trees is commonly known as deforestation. It has become a major issue as a huge number of trees have been cut down in the past years. The trees of tropical forests are mostly affected because of the abundance and variety of trees in this region. These trees include the softwoods and hardwoods. Examples of some softwood trees are spruce, rubber, pine, and fir, whereas, hardwoods include oak, maple, and hemlock. These trees are mostly used to make paper, wooden furniture, palm oil and also shampoos. In addition to this, the trees are also cut down for building houses, grazing of animals, agricultural purposes and used as fire to cook food in remote areas.
The cutting down of trees affects the trees and plant species, and also the fertility of the soil decreases. The organisms existing in this region are also affected due to their loss of habitat.
