Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.
Answer:
They perform photosynthesis, releasing oxygen into the atmosphere as a by-product.
Explanation:
Around the time that cyanobacteria appear around 3.2 billion years ago, the oxygen levels rise sharply.
Cyanobacteria are photosynthetic organisms. They possess the photosynthetic pigment chlorophyll, meaning they can trap light energy and use it to power chemical reactions to synthesise glucose. They convert carbon dioxide and water into sugar, releasing oxygen into the atmosphere as a byproduct. This causes oxygen levels to rise.
Answer:
Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2).As oxygen photosynthesis starts,that's when the first O2 producing of cyanobacteria occurs.The graph reaches a peak at Cambrian explosion.

According to the World Resource Institute, biodiversity is the variety of the world's organisms, including their genetic diversity. In a world of genetically modified (GM) crops, agriculture is greatly reducing the genetic diversity of the plants on Earth. By ignoring genetic diversity, while we develop GM products, we run several risks that include ALL BUT ONE listed here.
A. a disease or pest emerging that will wipe out the GMOs.
B. the extinction of many native or indigenous crops.
C. increase production while reducing environmental impacts.
D. reduced biodiversity of important food crops.
Answer:
C
Explanation:
The correct answer is: increase production while reducing environmental impacts. This is because genetically modified (GM) crops are often designed to increase production and reduce environmental impacts, such as the use of pesticides and herbicides. However, the development and widespread use of GM crops can also reduce the genetic diversity of plants on Earth, which can have negative effects on biodiversity and lead to other risks such as the emergence of diseases or pests that can wipe out the GMOs, and the extinction of native or indigenous crops. Therefore, ignoring genetic diversity while developing GM products can lead to negative consequences for agriculture and the environment.
1. Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species. Finch populations with a certain beak shape thrived, while those not having that beak shape decreased, Which of the following describes a necessary condition for thesechanges in the finch populations to occur?
Answer:
A necessary condition for the changes in the finch populations to occur in response to the drier climate would be:
- Variation in beak shape within the initial population: There must have been existing genetic variation in the population of finches regarding beak shape. Some finches would have had the beak shape that provided an advantage in obtaining food resources in the drier climate, while others would have had different beak shapes.
Without this initial variation in beak shape, there would be no opportunity for natural selection to act and favor individuals with the advantageous beak shape. Therefore, the presence of genetic variation within the population is necessary for the changes in the finch populations to occur.
Based on the theory of natural selection, the necessary condition for the changes in the finch populations to occur is limited food resources. Option B
What does natural selection say?Natural selection is the process by which populations of living organisms adapt and change over time.
Natural selection occurs when there is variation within a population of a species, and some individuals are better able to survive and reproduce than others.
These individuals are more likely to pass on their genes to the next generation, and the population will gradually change over time.

the membrane depolarizes.
When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.
Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

Plan an Investigation Design a controlled
experiment to demonstrate that birds do not
spontaneously generate on birdfeeders.
Hypothesis: Birds do not spontaneously generate on birdfeeders.
Experimental design:
Obtain two identical birdfeeders and fill them with birdseed of the same brand and type.
Place both birdfeeders in the same location, one on the ground and the other hanging from a tree or pole.
Randomly select a time of day to check the birdfeeders and record the number of birds on each feeder.
Repeat the experiment for a minimum of 7 days to collect sufficient data.
Analyze the data collected and compare the number of birds on each feeder to determine if there is a statistically significant difference.
Control:
The control in this experiment is the birdfeeder on the ground, which serves as a baseline for the number of birds that naturally visit the area.
Variables:
Independent variable: The location of the birdfeeder (ground or hanging).
Dependent variable: The number of birds on each feeder.
Potential confounding variables:
Weather conditions: Wind, rain, and temperature can affect bird behavior and may influence the results.
Time of day: Some birds are more active in the morning or evening, which may impact the number of birds observed.
The type of birdseed used: Different types of birdseed may attract different birds, which could affect the results.
To control for these variables, the experiment should be conducted at the same time of day and in similar weather conditions. The same type of birdseed should be used for both feeders to eliminate differences in bird preference.
The excessive and unbalance use of pesticides is one of the prominent environmental issue since last few years in Nepal. Mention any three consequences of over use of pesticides in your locality and suggest awareness campaign that you have follow in two points. [3+2]
The excessive and unbalanced use of pesticides is a prominent environmental issue in Nepal that can have several negative consequences. Here are three consequences of overusing pesticides in a locality:
1. Harm to human health: Overuse of pesticides can lead to health problems such as skin irritation, respiratory issues, and even cancer. Farmers and their families who handle these chemicals regularly are especially at risk.
2. Soil and water contamination: Pesticides can seep into the soil and water, polluting them and making them hazardous for human and animal use. This can lead to long-term damage to the environment and make it difficult to grow crops in the future.
3. Harm to biodiversity: Pesticides can kill off beneficial insects and pollinators, which are important for maintaining a healthy ecosystem. This can lead to a decrease in biodiversity and harm to the overall health of the ecosystem.
To raise awareness about the negative impacts of pesticide overuse in a locality, an awareness campaign could be organized, which could include:
1. Educating farmers about the risks associated with excessive pesticide use and the benefits of using alternative methods such as integrated pest management.
2. Organizing workshops and training sessions for farmers on how to use pesticides safely, including proper handling and disposal of these chemicals.
Overall, raising awareness about the dangers of overusing pesticides and promoting safe and sustainable agricultural practices can help mitigate the negative impacts of pesticide overuse in a locality.
