Explanation:
The bowling ball will roll so thats a big change. I've done something like this with a deck of cards & soda cans & they will move more than a brick. Bricks have a lot of friction & weight, plus they're built to be sturdy & not move much so D is probably the right answer.

The Asian longhorned beetle is native to China and Korea. The beetle is thought to have entered the United States by means of untreated wooden packing crates. The beetle larvae make tunnels and feed on wood of a wide variety of trees like maple, elm, willow, and birch. Infestation by a large number of these beetles can result in the death of the trees.
Which is the best measure that the United States government can take to limit the introduction of more beetles?
Responses:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Prevent growing trees in and around shipyards.
Introduce predators of these beetles from China or Korea.
Require an inspection and treatment of all wooden packing materials before being imported.
Cut all trees that are infected or are at risk of being infested by the beetles.
Answers
My first answer would be to inspect all wooden packaging materials before being shipped, since that seems to be the way they are being transported from China and Korea to the United States.
My second answer would be to release predatory species concerning this native beetle species to evacuate or kill of the beetle community in the United States. Although, that could create more problems with more non-native species (of the United States), reasoning the first answer to be the best.
The other answers would most likely be worse, since the extermination of possibly infected trees would just kill the trees, which is something we are trying to stop from happening. If we prevent those trees from growing in/around shipyards, the species could still travel through the packaging if it is brought further onto land or use other modes of transportation. Also, the trees were already growing there in the first place, so then 'preventing' them from growing would just lead back to killing the trees that could be infested.
Answer:
Explanation:
Prevent growing trees in and around shipyards.

The second pair contrasts the consequences of disobedience (discipline and limitations) with the outcomes of honoring parents (greater freedom and trust).

In which bottles did fermentation occur? How do you know this?
Answers
Answer:
Bottle 2 and bottle 4
Explanation:
Whenever fermentation occurs the liquid experiences natural carbonation in a way. For example if you've ever seen a bottle of kombucha you'll see that it's constantly bubbly and it never stops bubbling. So the production of oxygen inflated the balloons.
In the bottle named as bottle 2 and bottle 4 is showing fermentation, as per the given scenario.
What is fermentation?Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the foaming that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.
In the absence of oxygen, carbohydrates are broken down by the enzymes of microorganisms during fermentation.
Because they possess distinctive sets of metabolic genes, microorganisms like bacteria and fungus are able to develop enzymes that can break down various kinds of sugar compounds.
Although fermentation can result in a variety of products, the most prevalent ones are ethanol, lactic acid, carbon dioxide, and hydrogen gas.
Commercial applications for these materials include use in food, vitamins, medications, and industrial chemicals.
Thus, in bottle 2 and bottle 4, one can see the inflated balloon which can be an evidence of the fermentation taking place.
