Okay, let's break this down step-by-step:
1) Jessica originally trapped, marked and released 20 woodlice. So the 1st sample = 20.
2) 3 days later, she trapped 15 woodlice total. So the 2nd sample = 15.
3) Of the 15 woodlice trapped on the 2nd day, 10 of them had marks. So the 2nd sample that had been marked = 10.
4) Plugging this into the formula:
Population size = 1st sample × 2nd sample ÷ 2nd sample that had been marked
= 20 × 15 ÷ 10
= 300
Therefore, the estimated population size of the woodlice in the garden is 300.
Did I interpret the problem and formula correctly? Let me know if you need more details.

The equation for the light-dependent reactions of photosynthesis is:
2 H2O + 2 NADP+ + 3 ADP + 3 Pi + light → O2 + 2 NADPH + 3 ATP
The equation for the light-independent reactions of photosynthesis is:
3 CO2 + 9 ATP + 6 NADPH + 6 H+ → C3H6O3-phosphate + 9 ADP + 8 Pi + 6 NADP+
What are the light-dependent and the light-independent reactions of photosynthesis?The light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts and involve the absorption of light by pigments such as chlorophyll.
This light energy is used to split water molecules into oxygen gas (O2) and protons (H+), generating ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) in the process.
The equation for this process is:
2 H2O + 2 NADP+ + 3 ADP + 3 Pi + light → O2 + 2 NADPH + 3 ATP
The light-independent reactions of photosynthesis also known as the Calvin cycle, occur in the stroma of the chloroplasts and use the ATP and NADPH generated in the light-dependent reactions to fix carbon dioxide (CO2) into glucose.
The equation for this process is:
3 CO2 + 9 ATP + 6 NADPH + 6 H+ → C3H6O3-phosphate + 9 ADP + 8 Pi + 6 NADP+

The splanchnic nerves contain preganglionic axons of the sympathetic nervous system.
True or false
Answer:
True
Explanation:
The given statement "The splanchnic nerves contain preganglionic axons of the sympathetic nervous system" is true because these axons synapse with postganglionic neurons in ganglia located near or within the organs they innervate.
The splanchnic nerves are a group of nerves that originate in the thoracic and lumbar regions of the spinal cord and innervate the viscera. They are part of the sympathetic nervous system, which is responsible for the "fight-or-flight" response.
The preganglionic axons of the sympathetic nervous system are short axons that originate in the spinal cord and synapse with postganglionic neurons in ganglia located near or within the organs they innervate. The splanchnic nerves contain the preganglionic axons that innervate the viscera of the abdomen and pelvis.
The postganglionic axons of the sympathetic nervous system are longer axons that originate in the ganglia and innervate the organs they innervate. The postganglionic axons of the splanchnic nerves release the neurotransmitter norepinephrine, which activates the sympathetic receptors on the organs they innervate.

Darwin's Theory of evolution suggests that fishes evolved into amphibians. If this statement
is assumed to be true, explain why fishes still exist on the planet.
Answer:
Darwin's theory of evolution does not suggest that one species directly evolves into another species. Instead, it proposes that species can evolve from common ancestors over a long period of time through a process of natural selection. Therefore, the fact that fishes still exist on the planet does not contradict Darwin's theory. Here are some possible reasons why:
Diversification: Fishes have diversified into many different species over time, each adapted to a particular environment and niche. Therefore, the fact that some fishes evolved into amphibians does not mean that all fishes disappeared.Environmental factors: The evolution of fishes into amphibians may have been driven by changes in the environment, such as the availability of water or the development of new predators. However, not all fish species would have been affected equally by these changes, and some may have continued to thrive in their existing habitats.Adaptation: Fishes have evolved many different adaptations that allow them to survive in various environments. Some fish species are well-adapted to living in freshwater, while others are adapted to saltwater or deep-sea environments. These adaptations have allowed fish species to survive and thrive in different ecosystems.Evolutionary time: The evolution of species takes place over a very long period of time, and it is not necessarily a linear or predictable process. Even if some fish species did evolve into amphibians, it is possible that other fish species continued to evolve and diversify in other ways, leading to the continued existence of fish on the planet.In conclusion, the fact that fishes still exist on the planet does not contradict Darwin's theory of evolution. Evolution is a complex and ongoing process, and the survival of different species depends on a variety of factors, including environmental conditions, adaptation, and diversification.

A gene is a unit of heredity that is responsible for the inheritance of a particular trait from parents to offspring.
What are the principles of natural selection?The four principles of natural selection are:
Variation: Individuals within a population exhibit differences in their traits or characteristics.
Inheritance: Some of these variations are passed from parents to their offspring.
Selection: Individuals with certain variations that make them better adapted to their environment are more likely to survive and reproduce.
Time: Over many generations, the frequency of advantageous traits increases within the population, leading to evolutionary change.
A species is a group of individuals with similar physical and genetic characteristics that can interbreed and produce fertile offspring.
Genetic drift is the movement of alleles from one population to another due to chance events, such as the migration of individuals.
The term that refers to the evolutionary history of a species is "phylogeny".
Phylogeny is the study of the evolutionary relationships among organisms and their history of descent from a common ancestor. It is based on the comparison of anatomical, genetic, and other characteristics among different species.

describes the impacts that you have on the natural habitats where you live. In constructing your post, be sure that you thoroughly address the following questions IN PARAGRAPH FORMAT:
What resources do you use? Consider the resources (ex. fuel, electricity, food, water, etc.) you use on a day to day basis, but also in the long-term.
Where does your garbage go? Not just the dump, but what do they do with it??
How does how much you drive affect the environment?
What about buying food?
How does this all have an effect on the natural environment?
How could you lessen the effect?
As individuals, we use various resources on a day-to-day basis, including fuel, electricity, food, water, and other resources. In the long-term, our usage can have a significant impact on the natural habitats surrounding us. The more we use resources, the more we contribute to the depletion of natural resources, which in turn can lead to the destruction of habitats.
Garbage disposal is another significant factor that affects the environment. Most of the garbage that we produce is sent to landfills, which not only takes up a lot of space but also pollutes the environment. The garbage disposal process, such as incineration, can also cause air pollution and release harmful gases into the atmosphere.
Driving, particularly long distances, can significantly impact the environment. The more we drive, the more fuel we consume, which in turn contributes to air pollution and greenhouse gas emissions, leading to global warming and climate change. Similarly, buying food also has an environmental impact. The transportation of food products from one place to another contributes to air pollution, and the use of fertilizers and pesticides in agriculture can contaminate soil and water resources.
All of these factors have a significant effect on the natural environment. The depletion of natural resources, the pollution of air and water, and the destruction of habitats all have significant impacts on the planet's biodiversity and ecosystem.
To lessen the effect, we can adopt more environmentally friendly practices. We can reduce our usage of resources by conserving energy, reducing water consumption, and using public transportation or carpooling. We can also reduce our impact on the environment by reducing the amount of waste we produce, recycling, and properly disposing of hazardous waste. Additionally, we can support local agriculture, which can reduce the transportation of food products and promote sustainable farming practices. By taking these steps, we can help preserve natural habitats and contribute to a healthier and more sustainable planet.

In physics, "hotness" is not a term that is used. The concept that is usually referred to in relation to temperature is "thermal energy", which is the total kinetic energy of the particles that make up a substance. When the thermal energy of a substance increases, its temperature also increases, which we perceive as the substance becoming "hotter".
The warmest summers in the Northern Hemisphere occur when the hemisphere is tilted toward the sun and receives the most direct sunlight. This occurs during the summer solstice, which happens around June 20-22 each year. The axial tilt is responsible for the seasons, and the precession of the Earth's axis does not have a significant effect on the timing of the seasons.
