Answer:
a & c.
Explanation:
small local populations depend on a specific food source. If the food source is depleted because of the existing populus, chances are, there will be no reproduction. If the populus, does not look beyond their boundaries for food, the species will die.
I do not agree, only because there have been so many children to play with toys like that, and they have been perfectly fine, so its like a one out of million chance.
Answer:
1. Gene Therapy.
Explanation:
As mentioned in the question, Cystic fibrosis is caused by a mutation in a gene resulting in changes to a protein that regulates the movement of salt in and out of cells.
What is gene therapy:
- If we talk about gene therapy, it is a process in which we replace a wrong gene with a right gene.
- it is a novel and fascinating area of genetic engineering through which we can treat many genetic disorders including Cystic Fibrosis. However, those experimentation of gene therapy are in trial processes.
So now the question is that why Cystic fibrosis can be treated with gene therapy?
- The answer is because we already know that cyctic fibrosis is a genetic disorder that is a genetic defect.
- We also know which gene is defected in this case which is called CFTR gene.
- We also know the target tissue in which damage is caused due to genetic defect and that tissue is lungs.
- So, there are 50% chances that if we transfer correct CFTR gene in place of defected CFTR gene of patient, the disease can be treated.
Current research:
- In recent few years, experimentation have been made in which Retroviral vectors have been used to transfer the CFTR gene into cultured cells which means outside the body.
- So, if the experiments of same nature are proceeded in future in which CFTR gene is transferred in the body of the patient, it can lead to the division of cells with correct CFTR gene and treatment of disease.
- In some cases the CFTR gene has been expressed and the protein has been formed which improved the physical condition of the patient. Some other clinical trials have proved that correct CFTR after transfer into the patient through appropriate vector has succesfully expressed itself.
- However, more solid research and clinical trials are required to treat Cystic fibrosis through gene therapy and make it a best and easiest option for the treatment of disease.
Hope it help!
Answer:
14. Carcinogenic
15. Not sure. I believe it is monoclonal antibodies.
What results? We don’t know what you’re talking about so we have nothing to base our answer on. Next time you could provide a picture of the results or what brought to the results. Sorry but this question is un-answerable.
