How do wetlands reduce flooding and erosion? (Site 1)
Answer:
by absorbing water and then releasing it slowly.
Explanation:
Answer:
Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage and braking action lowers flood heights and reduces erosion.
Why are wetlands referred to as "biological supermarkets"? pt.2 for edn2020
Wetlands within and downstream of urban areas are particularly valuable, counteracting the greatly increased rate and volume of surface- water runoff from pavement and buildings. The holding capacity of wetlands helps control floods and prevents water logging of crops. Preserving and restoring wetlands together with other water retention can often provide the level of flood control otherwise provided by expensive dredge operations and levees. The bottomland hardwood- riparian wetlands along the Mississippi River once stored at least 60 days of floodwater. Now they store only 12 days because most have been filled or drained.

What effects genetic variation and environmental factors have on organisms
Answer:
Explanation:
Evolutionary psychology seeks to understand the adaptive, evolved nature of humans by considering the forces of natural selection that gave rise to it. Individual humans also exhibit maladaptation, however, and some of the variation in maladaptive conditions is heritable. An evolutionary perspective can shed light on these phenomena too. Recent work suggests that developmental imprecision importantly affects the fitness of organisms and some of the genetic influences have been identified. Both theory and evidence that developmental imprecision underlies human cognitive maladaptation has begun to accumulate, although the manner in which the developing brain is affected remains largely unknown.
Should the FDA should give Aquabounty permission to grow and sell transgenic salmon? Why or why not?
Answer:
Yes it should be approved
Explanation:
The FDA should give Aquabounty permission to grow and sell transgenic salmon because studies have shown that transgenic salmons which are genetically modified are harmless. This finding has allayed the fears of the people. Permission to grow and sell this type of salmons will make it easier for transportation to other parts of the country because it doesn’t necessarily have to come from the sea. It also ensures there is increased availability of the products all over the country.

List ways that you can reduce, reuse, and recycle waste that you typically generate
Answer:
I typically generate a lot of paper as waste while using paper to write. I can follow the following ways to reduce, reuse, and recycle the paper waste.
When I photocopy a large document, I could reduce my use of paper by making double-sided photocopies, or I could only copy the portion of the document that I would actually use.
When I am done with a single-sided document, I can reuse the other side as scrap paper for working on math problems.
Finally, when I am done with my paper, I can recycle it instead of throwing it into the garbage. Many recycling centers accept paper. Moreover, there are bins for recycling near my school.

Scientists have incorporated a barley gene into a type of rice and produced rice plants that have much lower methane emissions. It is most likely that the scientists incorporated the barley gene into the rice, producing a new variety, using the process of ___________.
Answer:
The correct answer is "genetic engineering".
Explanation:
The missing options of this question are:
(1) selective breeding
(2) meiosis, followed by recombination
(3) genetic engineering
(4) sexual reproduction, followed by mitosis
The correct answer is option (3) "genetic engineering".
Genetic engineering is a modern technology that uses a DNA recombinant approach to alter the genetic material of an organism. In this case the genetic material of rice was modified by incorporating a new gene that is originated from barley. The transference of a gene from an organism to another is most easily achieved by genetic engineering technology.

Which of the following is a disadvantage of using solar energy?
A. Solar and angels are expensive
B. Solar energy is available only during summer
C. Solar panels do not work very well
D. Solar energy produces greenhouse gases
Answer:
a
Explanation:
Solar energy is expensive and solar energy works during every season, however the productivity drops, hence option A is correct.
What is the use of solar energy?The fact that solar energy might be temporarily disrupted by weather is one of its drawbacks. The amount of electricity you create is less on cloudy days. However, the cold has little impact on output.
Any energy produced by the Sun is referred to as solar energy. Direct or indirect human usage of solar energy is possible.
Solar energy is captured and transformed into power by these solar panels, which are installed on a roof. Solar water heaters and home heating are two common uses for solar energy.
Therefore, solar energy can also be used for cooking and as a source of power for technological equipment.

It may be that there are no cavity-nesting birds in your yard. Only certain species of birds will use houses, and if you know which birds those are, you can add feeders, water features, and shelter to make the yard more attractive to those species. As they get more comfortable with your yard, they will start to check out the available nesting sites, including birdhouses.

Birds Build Nests Before My Birdhouses Are Ready
Spring Flowers in Snow
If you’re waiting until spring flowers bloom to put up birdhouses, it may be too late to attract the first nesters. Early-nesting birds, however, may still investigate the house for additional broods later in the season. Putting houses up earlier can help attract the earliest nesting species and ensure the houses are ready for residents. Ideally, have houses ready to go in late winter to be available for every nesting bird.

Birds Build Nests Lower Than My Birdhouse's Height
Tree Canopy
Where you mount a birdhouse is just as critical as the size and shape of the house itself. Some birds will use higher houses, while others prefer houses closer to the ground. Birds nest at different heights and have different preferences for whether the house is mounted on a pole or tree, or if it can be hung. Understanding birds’ preferences can help you position birdhouses properly.

Birds Never Reuse Old Nests
Old Bird Nest
Most nesting songbirds will not reuse old nests, though they may reuse a small amount of the nesting material to build a fresh nest. The best option is to clean out birdhouses after every brood has fledged so the house is clean and clear for another pair of nesting birds to use. This also reduces the risk of dangerous contamination from old feces, feather mites, or insect infestations in an old nest.

I Want to Take My Birdhouses Down in Winter but Birds Are Still Using Them
There can be a wide range of difficulties with birdhouses, but there are also easy ways to fix each problem to make the houses more attractive to nesting birds.
What do you mean by nesting birds?Some birds do not make nests at all and instead lay their eggs in a simple scrape in the ground. Other birds construct nests from natural materials, such as grass, leaves, mud, lichen, and fur, or from human-made materials like paper, plastic, and yarn.
Birds don't vigorously tear up mouthfuls of grass, pluck out their own feathers, pull threads out of outdoor rugs, or peel the screens off windows for no good reason.
The time for incubation varies widely from species to species. Roughly speaking, small songbirds take between 10 days and 2 weeks to hatch and the same amount to fledge. Larger birds such as woodpeckers may take 3 weeks to a month to fledge.
