Answer:
7 followed by 27 zeros
Explanation:
The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.
The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.
In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.
Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.
Explanation:
DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.
<u>Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA.</u> In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).
In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.
The correct answer is (c) determining how to manage global resources for all humanity
The goal of the world resource simulation center is a very large platform to manage global resources in the form that it serves to all humanity. The team there compiles the inventory of resources, analyses and assess the resources to solve the current problem as well as anticipated problem. They take help of the emerging technology to solve the problems more precisely. The technology there helps to examine the in-depth problems associated with resources.
