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.

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.

Explanation:

Answer:

Explanation:

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

R = 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
