Solar, wind, wave, and nuclear energy are all ways of producing
energy without producing the negative outcome of:
Select one:
1, Decreased oxygen levels
2, Habitat loss
3, Increased greenhouse gas emissions
4, Non-native species
Answer:
3. Increased greenhouse gas emissions
Explanation:
Solar, wind, wave, and nuclear energy are all ways of producing energy without producing the negative outcome of increased greenhouse gas emissions. Greenhouse gases, such as carbon dioxide and methane, are released into the atmosphere through the burning of fossil fuels, such as coal, oil, and natural gas. These gases trap heat in the atmosphere and contribute to global warming and climate change. Solar, wind, wave, and nuclear energy, on the other hand, are forms of renewable energy that do not produce greenhouse gases when they are generated. They are considered more environmentally friendly alternatives to fossil fuels, and their use can help to reduce greenhouse gas emissions and mitigate the impacts of climate change.

A) The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity. Explain the three levels of biodiversity and the concerns associated with loss of diversity at each level.
B) Species and genetic diversity can be very beneficial to humans. Describe three ecosystem services that nature provides to humans.
Answer:
Biodiversity or Biological diversity is a term that describes the variety of living beings on earth. It is described as degree of variation of life. Biological diversity encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.
-In biodiversity, each species, no matter how big or small has an important role to play in ecosystem. It represents the wealth of biological resources available to us. It’s all about the sustaining the natural area made up of community of plants, animals, and other living things that is begin reduced at a steady rate as we plan human activities that is being reduced by habitat destruction.
Explanation:
A) The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity.
B) Ecosystem services provided by biodiversity include pollination, pest control, and nutrient cycling.
A) The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity. Genetic diversity refers to the variation in genes within a species, which allows populations to adapt and survive in changing environments. Concerns associated with the loss of genetic diversity include reduced adaptability to environmental changes and increased vulnerability to diseases.
Species diversity refers to the variety of different species within an ecosystem. Loss of species diversity can disrupt ecological balance, impact food webs, and lead to the extinction of keystone species. It can also result in the loss of potential sources for medicines, agricultural crops, and other valuable resources.
Ecosystem diversity refers to the variety of different ecosystems in a region. Loss of ecosystem diversity can result in habitat loss, fragmentation, and degradation, leading to the decline or loss of specialized species adapted to specific habitats. It can also impact the provision of ecosystem services, such as water purification, climate regulation, and nutrient cycling.
B) Species and genetic diversity provide several ecosystem services to humans. One example is pollination, where diverse species of pollinators, such as bees, butterflies, and birds, ensure the reproduction of flowering plants and agricultural crops. Another ecosystem service is pest control, where diverse predator species help regulate populations of agricultural pests.
Ecosystems also provide the service of nutrient cycling, where diverse decomposers, such as fungi and bacteria, break down organic matter and recycle nutrients back into the soil. This process is crucial for maintaining soil fertility and supporting plant growth. Lastly, diverse ecosystems contribute to climate regulation by absorbing and storing carbon dioxide, a greenhouse gas that contributes to climate change.
Overall, species and genetic diversity support the functioning and resilience of ecosystems, benefiting human well-being by providing essential services like pollination, pest control, nutrient cycling, and climate regulation. Protecting and conserving biodiversity is essential for maintaining these services and ensuring a sustainable future.

You are hired by Murphey Farms to decrease the backfat in their hogs. The current hog population has a mean backfat content of 20.2mm. You selected the hogs with the smallest amount of backfat, mated them and obtained the progeny generation. The selected hogs had a mean backfat content of 9.5mm. You know that the heritability for percent backfat in hogs is 0.47.
1. What is the selection differential? Round your values properly to 2 decimal digits.
2. What is the expected response to selection? Round your values properly to 2 decimal digits.
3. What is the expected mean of the progeny generation? Round your values properly to 2 decimal digits.
Answer:
SD = -10.7 R = -5.3X₁ = 14.9 ≅ 15mmExplanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.
Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.
The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,
SD = Xs - X₀
Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.
h² = R/SD
The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.
R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₁ - X₀
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
• You are decreasing the backfat in the hogs.
• The hog population mean backfat content = 20.2mm → X₀
• The selected hogs had a mean backfat content of 9.5mm → Xs
• Heritability is 0.47 → h²
According to what we sow previously, we need to find out the value of X₁, which reflects how tall the new generation of corn will grow.
• We know that R = X₁ - X₀, so we need to clear this formula to calculate X₁
X₁ = R + X₀
We already know that X₀ = 20.2mm
Now we need to calculate R.
• R = h²SD
We know that h² = 0.47,
Now we need to calculate SD
• SD = Xs - X₀
Xs = 9.5mm → Parentals media height
X₀ = 20.2mm → Population media Height
SD = Xs - X₀
SD = 9.5 - 20.2
SD = -10.7
Knowing this, we can calculate R
R = h²SD
h² = 0.47 SD = -10.7R = 0.47 x -10.72
R = -5.3
Finally, once we know the R-value we can calculate the X₁ value
X₁ = R + X₀
X₁ = -5.3 + 20.2
X₁ = 14.9 ≅ 15mm

A group of biologists working in Africa observed that some of the Acacia trees growing in their study plots had clearings around them, so that no other vegetation grew within a few meters around each tree. These trees were also covered with ants. The researchers hypothesized that the ants must have cleared the vegetation around each tree. To test this, the researchers decided to remove the ants from some of the trees by spraying with an insecticide and see if vegetation grow in the clearings with the ants gone. They located 100 Acacia trees with clearings and ants present, and sprayed half of them with insecticide. The trees tended to exist in two general habitats: the first habitat was much higher in elevation and was moisture, cooler, and had more wind exposure than the second habitat. Because the insecticide spray would have drifted in the windy conditions of the higher elevation habitat, the researchers only sprayed trees in the low elevation habitat. They visited their research location once a month for two years to record whether vegetation re-grew in the clearings. Which element of experimental design is missing or flawed in this experiment
Answer:
The project showed no control over the confounding variable.
Explanation:
The confounding variable are variables that can influence the dependent variables and that were not established by the researchers. These variables exist naturally in the experiment and are able to alter the result of the experiment in a very intense way.
The dependent variable, in the case presented in the question above, is the proliferation of vegetation around the Acacia plants, while the independent variable is the amount of ants present in the environment. As we can see these two variables are being controlled by the researchers, however, the confounding variables such as soil fertility, water availability, sunlight intensity, wind intensity, are not being controlled and this can severely damage the experiment.
The element of experimental design that is missing or flawed is that the experiment did not control any confounding variable.
CONFOUNDING VARIABLE:A confounding variable in an experiment is a variable that can influence the outcome of the dependent and independent variables.
