Answer:
diploid
Explanation:
So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.
Answer:toxic
Explanation:
A ureotelic organism excretes excess nitrogen as urea. Urea is less toxic and needs less water in comparison to Ammonia. Ureotelic organisms include cartilaginous fish, few bony fishes, adult amphibians and mammals including humans. The uricotelic organism excretes uric acid or its salts
The second one would be my answer but also an answer that is not up there is that during an experiment when repeating the trials you might have to set up a new hypothesis every time and have to review the data several different times because of different results from each trial
hope this helps if not just let me know
Answer:
a) Some island populations will have fixed one allele, and other populations will have fixed the other allele.
Explanation:
The founder population for each island is heterozygous for the locus. The absence of any migration and mutation would result in no gene flow or the introduction of new alleles of the locus. Over several generations, one or the other allele will be fixed in the populations depending on the adaptive features imparted by each under the different conditions present on these different islands. Genetic drift may also work on these small founder populations to randomly fix one or the other allele.
Answer:
Answers are below.
Explanation:
Advantages:
1. Could reduce the need for pesticides.
2. It may improve the nutrient composition and quality of food.
3. Might be able to resist pests and diseases.
4. Could find cures and medicine.
5. Artificially implanting DNA from one species to another can save many, many years of research.
Disadvantages.
1. The testing often involves performing experiments upon animals, which some people feel is a breach of animal rights.
2. Genetically Modified Organisms could affect those with allergies in many ways.
3. It could spread undesirable diseases or start an epidemic.
4. Often GMO products are not clearly labelled, meaning people do not have the choice to decide whether or not they wish to consume GMO products.
5. Transgenic modification produces organism types which would never occur naturally, making them highly unpredictable.
