Explanation:
Is Solid waste point source pollution or non point source pollution?
Answers
Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Hormones control some actions in the body. The nervous system controls some actions as well. Reflex actions are part of the nervous system.
Give TWO ways in which a hormone-controlled action is different from a reflex action.
Answers
Answer:
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurones, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. This means that communication is faster when using the nervous system.

1. What is an ecosystem?
2. What are some examples of nonliving things in an ecosystem?
3. What are some factors that could affect the number of organisms in an ecosystem?
4. Why might organisms interact in an ecosystem?
5. Would you expect to find the same kinds of interactions between organisms in very different ecosystems? Why or why not?
6. Why is it important to understand feeding relationships in an ecosystem?
Answers
Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.
Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.
Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.
Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.
Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.
Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
