Biology

Yakvenalex [24]3 years ago
5 0

Answer:

Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects.

The mutation rate is the probability of a single gene mutating in an offspring bug.
Ilya [14]

Answer:

True

Explanation:

A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/<em>locus</em>/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations <em>per</em> round of replication, <em>per</em> gamete, <em>per</em> cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of <em>de novo</em> mutations per nucleotide <em>per</em> generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ <em>per </em>gene <em>per</em> generation.

Nookie1986 [14]

Most of the work done in the field of resource technology occurs in :    

The computer system

<h3>What are technology resources ?</h3>

Technology resources are resources which are used for the production and dissemination of data. The work done based of these resource is first conceived and planned in the brain and mind of the creator, before the work is been done mostly using a computer system Technology resources include wireless data, video networks ,electronic storage devices and other forms of data extraction.

Hence we can conclude that Most of the work done in the field of resource technology occurs in : The computer system
