Answer:
Energy and nutrients are cycled throughout all the different components of the ecosystem. The non-living components like heat and nutrients are called abiotic factors. Both biotic and abiotic factors contribute to an environment's health. Biotic factors include plant productivity and animal behavior.
Possible contaminate will be Proteus or Salmonella. To differentiate the two genera urease test can be accomplished. However, urease test, Proteus will produce a positive test result.
This test can be done to determine the ability of an organism to split urea. The principle of urease test is that urea is the product of decarboxylation of amino acid. Splitting of urea via hydrolysis will produce ammnonia and CO2. The CO2 produce allows the formation of bubbles.
Answer:
Most genetic disease result from mutation that causes a gene to produce non functioning Protein.
Explanation:
Mutation deals with alteration of nucleotide sequence of the gene that encodes a functional protein product.
As a result of mutation the open reading frame of the mRNA sequence transcribed from that gene is being changed. Due to which the mutated gene can no longer form functional protein. This ultimately leads to production of non functional or truncated protein or disease causing protein.
For examle the Sickle cell anemia is caused due to the mutation in the beta chain of hemoglobin resulting in the accumulation of insoluble aggregates of HbS .
