The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.
Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age.
two strands of DNA are held together by weak hydrogen bonds.
Answer:
In the form of bicarbonate dissolved in the plasma.
Explanation:
A large part of the carbon dioxide is transported dissolved in the plasma. And 10% of CO2 is transported as carbaminohemoglobin.
85% of CO2 Its converted to bicarbonate in the red blood cells of tissues
An enzyme needs to match the active site so they can interact in a precise matter. they are specific because they each have a certain thing to do.
The most significant difference between biofuels and fossil fuels is that biofuels are: produced with biomass, that is, they are processed energy resources that come from organic compounds extracted from wild or cultivated plants.
Fossil fuels (such as oil, coal, and natural gas) are those that come from the natural decomposition of organic matter.
They are called non-renewable energies because they are limited natural resources since they require an extensive period of time and specific conditions to form.
On the other hand, a biofuel is a term that is used to refer to all those fuels produced from biomass, that is, through the chemical or physical treatment of organic or plant waste.
That is, unlike fossil fuels that come from energy stored for long periods in fossil remains, biofuels come from biomass, or organic matter that constitutes all living beings on the planet.
- Biomass is a renewable energy source, as its production is much faster than the formation of fossil fuels.
- The use of biofuels as a renewable energy source can help reduce the consumption of fossil fuels, responsible for the generation of greenhouse gas emissions.
During its production, part of the carbon dioxide that could be released into the atmosphere is extracted from the biomass.
For this reason, biofuels do not contribute to the emission of greenhouse gases.
Therefore, we can conclude that the most significant difference between biofuels and fossil fuels is that biofuels are: produced with biomass.
