Answer:
In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides. MORE water will move up the concentration gradient, thus there is a net flow up the gradient.
Explanation:
Bar graphs are graphs that can be used to display quantitative or qualitative.They are useful for quantitative or qualitative data. With qualitative data, the frequency or percentage of occurrence can be displayed. With quantitative data, the measurement itself can be displayed..
Answer:
before water would boil, the pot has to be hot first before the water because the heat from the burner will pass through the metal pot because the metal pot is a good conductor of heat and the heated metal will cause the water to warm... therefore it is assume that once the metal pot is hot the water is warm
Answer:
Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. It can breed and spread quickly, taking over an area. Native wildlife may not have evolved defenses against the invader, or they may not be able to compete with a species that has no predators.
The direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing or killing a native species' young.
There are indirect threats of invasive species as well. Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife. Aggressive plant species like kudzu can quickly replace a diverse ecosystem with a monoculture of just kudzu. Additionally, some invasive species are capable of changing the conditions in an ecosystem, such as changing soil chemistry or the intensity of wildfires.
Here are some examples:
- Cogongrass is an Asian plant that arrived in the United States as seeds in packing material. It is now spreading through the Southeast, displacing native plants. It provides no food value for native wildlife and increases the threat of wildfire as it burns hotter and faster than native grasses.
- Feral pigs will eat almost anything, including native birds. They compete with native wildlife for food sources such as acorns. Feral pigs spread diseases, such as brucellosis, to people and livestock. E. coli from their feces was implicated in the E. coli contamination of baby spinach in 2006.
- European green crabs found their way into the San Francisco Bay area in 1989. They outcompete native species for food and habitat and eat huge quantities of native shellfish, threatening commercial fisheries.
hope this helps!!:)
Explanation:
Answer: the question is not detailed enough
Explanation:
For instance if the genotype of the parent is AS and AS there would be a cross breeding of the genotype to give the First filial generation (F1) then any other crossbreeding is known as the F2
Note: the parent genotype is known as P1
