That as you increase in trophic level 1/10th of the nutrients is lost. Starting at the consumers (plants) all the way to humans.
Answer:
a. most genes encode one polypeptide and can be operationally defined by the complementation test
Explanation:
Genes are the stretch of DNA that code for specific polypeptides. In general, one gene codes for the only polypeptide.
Genes are defined by complementation tests which in turn tell if two mutations have occurred in the alleles of the same gene or different gene.
For the purpose, an organism with the homozygous genotype for one recessive mutation is crossed with an organism having the homozygous recessive genotype for another mutation.
If the two mutations are in the same gene, the progeny would show the mutant phenotype. On the other hand, if two mutations are in different genes, the progeny would exhibit normal phenotype.
Answer:
transcription used dna because the mRNA is built on the DNA template . translation used RNA replication dna
Explanation:
A high level of biodiversity leads to a better sustainability of the natural environment.
- Biodiversity is the variation of plant and animal species in an ecosystem.
- The natural environment deals with the living and non-living part of the ecosystem.
- A wide range of diversity in the ecosystem brings in broader level of interaction among the different constituents of the environment.
- Biodiversity ensures there is no over dependence on a particular resource in the environment. Organisms have access to a pool of resources.
- In adverse times, it ensures that quite a number of organisms are still able to live and thrive well.
