Summary Introduction

To write:

The way in which humans have affected their natural environment. The effects of these doings on the natural environment.

Introduction:

The natural environment includes all the living and non-living things that occur naturally. It involves the interaction between the living species, weather, climate, and natural resources. It has an impact on economic activity and human survival.

Expert Solution & Answer

Explanation of Solution

Humans have shown their impact on the environment in several ways.

1. Decreased water quality: Due to the misuse of water resources by humans and dumping of wastes into the water bodies. There is a decline in the quality of water.

2. Increased pollution: Unfavorable activities and disturbances in the environment has led to various types of environmental pollutions. Activities like cutting of trees, soil erosion and release of pollutants in water lead to the soil and water pollution respectively.

3. Greenhouse gas emissions: Due to the urbanization, the deforestation process has increased in the last few decades. This results in the rise of greenhouse gases like CO2. This gives rise to an increase in the temperature of the atmospheric layer. Finally, global warming is the result.

4. Depletion of natural resources: Due to a vast increase in human population there is an increased demand for the resources. So, resultant is the depletion of more and more natural resources.

5. Contribution to global climate change: As there is an increase in greenhouse gases, there is an increase in global warming. This global warming is making variations in the temperature of the global atmosphere. This change is then producing the overall global climate change.

These are the common effects of human activities on the natural environment. These effects have led to a disbalance of the total natural environment.

Conclusion

Thus, there are the common effects of human activities on the natural environment like, decreased water quality, increase in pollution, greenhouse gas emissions, global warming, depletion of natural resources. These effects have led to a disbalance of the total natural environment.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent.  b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involved
