What kingdom did the first organisms on earth belong to? Which of the following is an example of a basic need for all organisms? a. sunlight b. soil c. oxygen d. food Was the amphibian the first organism on land
In addition, it is important to consider the wealth of knowledge on the organism’s physiology and metabolism as well as the degree of development of techniques for strain engineering [5]. A given bioprocess can also be improved by the optimization of fermentation conditions and evolutionary ...
The Earth is thought to be over 4.5 billion years old. The first life that appeared on Earth was about 3.77 billion years ago. We cannot definitively say what the first organism was; our educated guess is that it must have been a prokaryote....
This almost seems self evident but there was some publicity last year for Hannah Ritchie’s book, “Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet” and she also did a TED talk with a similar title. She redefined “sustainability” as low env...
The following factors need to be borne in mind when one considers the importance of a compound as a pollutant: When thinking about toxicants, it is important to remember that all compounds can become toxic, if an organism gets too much of them. This is particularly well demonstrated with met...
isolates that phylogenetically belong to the species are nonpathogenic and exist as commensals on plants. Understanding the genetic and phenotypic diversity ofP. syringae, especially in comparison to its closely related nonpathogenic bacteria, has helped to elucidate what makes this organism a pathogen....
Today, we know that healthy eating is important to keep our bodies in tip-top condition. This link between diet and health was first ‘proved’ in the mid-1800s by Scottish naval surgeon Dr Joseph Lind, who is credited with running one of the earliest ever clinical controlled trials. His...
This organic matter was constantly altered on its long journey towards our planet, its final composition the product of a singular history which scientists are now attempting to reconstruct.但是这些最终进入地球海洋的碳质物质经历了一系列的变化，特定的温度、特定的事件、特定的恒星、来自太阳的特定量的...
What was the smallest unit of living matter? What is the smallest unit of evolution? In which process, does an organism produce another organism like itself? What is the term for the smallest evolutionarily independent unit? Which is the smallest unit of life that can exist as a living, sep...
Copper (Cu) is required in eukaryotes for oxygen metabolism, oxygen radical detoxification and iron (Fe) uptake [1]. More recently, a role for Cu in the regulation of numerous other cellular processes via metalloallostery has been described. Metalloallostery refers to the ability of Cu to bind...
