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.

Explanation:
Plant cells have specialized structures which are absent in animal cells. These include cell wall, chloroplasts, and central vacuole. Thus, correct options are A, C, and E.
What is a Plant Cell?Plant cell is the basic unit of all plants. Plant cells have unique organelles which are absent in animal cells. These organelles are responsible for specific functions which are important for the normal functioning of plant cell.
Plant cells have a unique cell wall which is absent in animal cells. Cell wall is made up of cellulose which is responsible for providing strength to the cells. Plant cells also have a chloroplast which contain a special pigment called chlorophyll. This pigment is responsible for photosynthesis. This organelle is absent in animal cells.
A large vacuole is also found in plant cells which is absent in animal cells. The vacuole contains reserved food material in the form of starch which is used in the unfavorable condition.

Here the physical changes are seen in the burning candle, cooling candle, tearing paper, wet paper, salt, and water in the test tube, while the chemical reactions are involved in the burning of the paper and the mixing of the vinegar with soda.
What are the physical and chemical changes?The physical change is the change in form, such as when the candle is burned or cooled down, then the wax that is formed has the same properties as the candle, or the paper pieces after being torn have the same properties. Chemical changes involve the formation of new things, such as when paper is burnt, this produces ash with a different chemical nature, and when the vinegar and soda is mixed, it produces a different product.

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.

O Microorganisms reproduce asexually, producing identical offspring
O Corn is genetically modified and cloned to make identical crops
O Penguins reproduce sexually, producing offspring that look different from one another
O A banana tree branch is planted, producing a clone of the parent tree
Evolution by Natural selection occurs when the offspring of genotypes are produced in response to the environment. Hence the correct option is C Penguins reproduce, offspring that look different from one another.
Evolution by Natural SelectionCharles Darwin and Alfred Russel Wallace developed the theory of Evolution by Natural Selection. For evolution by natural selection take place, Darwin described four essential conditions, these are:
Trait selection must be variable in the populationThe trait must be heritableThe struggle of existenceThe organism which fits to its environment.As per the question, penguins produced offspring that look different from another, this must be because of the evolution by Natural selection.

Cross a white feathered chicken with a checkered chicken (checkered chicken, checkered chicken!). Show the genotypic and phenotypic ratios.
Answer:
The correct answer would be -
genotype - 50% WB and 50% WW
phenotype - 50% checkered chicken and 50% white-feathered chicken.
Explanation:
In the chickens, the checkered trait occurs due to the codominance type of inheritance as when two different alleles of color Black feather and White feather allele present together they both show their presence and express as checkered chicken.
White feather chicken: WW
Black feather chicken: BB
Checkered chicken: WB
Cross = WW and WB
gametes: W, W and W, B
Punnett square:
W W
W WW WW
B WB WB
Thus, The correct answer would be -
genotype - 50% WB and 50% WW
phenotype - 50% checkered chicken and 50% white-feathered chicken.
