what is the difference between sleet and freezing rain?
Answer:
Freezing rain comes when the cold layer is small. This doesn't allow the raindrops to fully freeze before hitting the ground. Sleet forms when there is enough time for the raindrops to freeze completely before hitting the ground
Explanation:
Sleet is already half-frozen, while freezing rain is icey cold and freezes when it hits the ground

Explanation:
Bacteria are economically important as these microorganisms are used by humans for many purposes. The beneficial uses of bacteria include the production of traditional goods such as yogurt, cheese, and vinegar. Microbes are also important in agriculture for the compost and fertilizer production.
Substance A's molecules are small. Substance B's molecules, which react with substance A to produce a blue-black color, are larger in comparison. If a solution of substance A is placed inside a selectively permeable bag, and the bag is placed in a solution of substance B, what will happen?
Here's link to the answer:
tinyurl.com/wpazsebu
When A reacts with B, it turns blue-black because the substance A is starch and its molecules are small, which is glucose. The substance B is iodine, which combines with starch to become blue black. If A is present in B, then the A will become blue black.
What is the reaction between the starch and the iodine?
Starch is a polymer that is made up of glucose monomer and is found in plant-based food products. This starch can react with iodine and produce a blue-black coloration, so when the substance A is placed in the substance B with a selectively permeable membrane, the substance B (iodine) can easily enter the starch and form the blue-black coloration. This is known as the starch-iodine reaction, and it results in a blue-black polysaccharide.
Hence, if a solution of substance A is placed inside a selectively permeable bag and the bag is placed in a solution of substance B, then the substance A (starch) will turn blue-black.

D. Lots of small plants, because the trees provide enough water.
(I'm in 5th grade btw, and I have a big test coming up so this could really help)
Answer:
A.....
Explanation:
,.............
If a forest has many large trees with lots of leaves, the likely thing that could be found on the ground is very few small plants, because the trees block all the sunlight. Thus, the correct option for this question is A.
Why do plants that live on the forest floor have big leaves?The forest floor gets almost no light at all. Leaves in these environments have adapted to low light and lots of water. Large leaves are arranged horizontally to absorb the most light possible. This is because these plants have plenty of access to water, and they can keep large leaves alive.
The plants that live on the floor of the forest have bigger leaves so that they can absorb the little light that comes through rather the plants that live in hot sunny conditions don't need to store as much sunlight. Cacti are plants that live in extremely dry environments.
Therefore, if a forest has many large trees with lots of leaves, very few small plants would be found on the ground because all the trees block the sunlight. Thus, the correct option for this question is A.

Scientists have genetically modified a variety of corn to protect it against 6 points
its predator, the corn borer. This variety of corn now produces a chemical
that is toxic to the corn borer. How will the genetic modification benefit
the entire ecosystem? *
The corn plant will be able to survive and produce more food for the ecosystem.
The chemical produced by the corn plant will be consumed by others in the
ecosystem.
The modified gene will mutate, and the new chemical produced will not be toxic to the
corn borer.
The corn plant will self-fertilize and cross-pollinate and continue to produce pest
resistant corn plants.
Answer:
the entire ecosystem? *
The corn plant will be able to survive and produce more food for the ecosystem
Explanation:
Considering a trophic web and competition for resources, we could say that the genetic modification benefit s the entire ecosystem because the corn plant will be able to survive and produce more food for the ecosystem.
---------------------
Assuming competition for resources between different species, and considering the trophic web, we could conclude that the genetic modification benefit s the entire ecosystem is because the corn plant will be able to survive and produce more food for the ecosystem →→→ Option A.
We need to think about the whole ecosystem when answering this question.
Let us think about the trophic web.
The trophic web is a relationship process between different organisms, through which occurs transference of energy. These organisms place at different levels. The ones placed at lower levels pass energy to the ones at the higher levels. Each level feeds on the anterior one and gets eaten by the next one. As it is a web, all organisms are equilibrated until a change occurs. When the change affects any of the involved links, there can be a cascade effect on the web. A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link. Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.In the exposed example, we will assume the corn borer was a successfull competitor and was preying on the corn. When eliminating it by the action of the toxic chemical, other organisms will experience a repercussion.
As the corn borer dies, the corn plant grows better and faster.
It might develop more foliage, flowers, and fruits, which might be acting as sources of food and shelter for different species.
Many other species might benefit from this genetic modification.
The corn plant development provides food, shelter and protection for many other species.The corn borer death means less competitive pressure for many other species.The other options.
B) The chemical produced by the corn plant will be consumed by others in the ecosystem. ⇒ Depending on the chemical, it cause no effect on other species, or might affect them. In any case, it is not beneficial for ecosystem.
C) The modified gene will mutate, and the new chemical produced will not be toxic to the corn borer ⇒ If this was the case, the corn plant would still be affected and the predator would still preying on the plant.
D) The corn plant will self-fertilize and cross-pollinate and continue to produce pest resistant corn plants ⇒ This would not involve other species.

URGENT Which of the following best explains why there are seldom more than five trophic levels in a food chain?
O The ecosystem contains too much biomass living mass)
O Most carnivores function at more than one trophic level
Top cami vores are too few in number to prey effectively
O Energy is lost from each trophic level
The statement that best explains why there is usually not more than five trophic levels in a food chain is that Energy is lost from each trophic level.
A food chain shows the transfer of energy and nutrients from organisms to organisms in a feeding pathway.
Each step along a feeding pathway is known as a trophic or feeding level.
This feeding pathway in nature follows a certain pattern:
It starts with a primary producer( the grass).the primary producer is eaten by a primary consumer (example, the zebra);the primary consumer is eaten by a secondary consumer (example, the lion);decomposers converts the remains of dead producers and consumers.At every trophic level, some of useful energy is lost as heat energy. Thus as we move along the food chain, the amount of useful energy decreases progressively.

Answer:
. because wild life is a renewable natural resource
A private reptile breeding facility near the Everglades was destroyed by Hurricane Andrew in 1992. This event contributed to the original influx quantities of pythons in the wild. Pet owners also contributed to the introduction of these reptiles to the Everglades by releasing pets that had grown too large to care for. These reptiles are considered species to this ecosystem.
can someone please write an explanation that describes the impact of the Burmese python on the Everglades?
Claim:
Evidence:
Reasoning:
Answer:
Claim:
The increase in the population of the Burmese python in Everglades is affecting the ecosystem of said area. They are an invasive species.
Evidence:
From 1994 to 2007, the Burmese python population increased from a small number below 50 species to more than 250 by 2007. As the Burmese population increased, the mammals' population in Everglades decreased significantly and even had extincted some species. For example, from 1993 to 1999, there were 64 white-tailed deer and five red foxes, and grey foxes. Between 2003 and 2011, there were 24 white-tailed deers and 0 foxes. Overall, there is a decrease in all mammals.
Reasoning:
The increasing number of Burmese Pythons due to the release of them by pet owners and due to the destructions of a private reptile breeding facility left a high number of pythons in the wild. As a consequence, these pythons ate other animals producing an imbalance in the Everglades ecosystem. Owing to its large number and how they are harming the ecosystem, they are considered an invasive species.
Explanation:
After analyzing the information, the claim is that the increasing population of pythons harms the Everglades' ecosystem.
The evidence that supports the claim is present in the graphics, where we can see how the population of this reptile grew over the years, and the mammals' population decreased. There is specific information about the reduction in the number of mammals in the area, such as the raccoon, foxes, rabbits, etc.
After presenting the evidence, the reasoning that we can make is that the pythons are killing the other animals in Everglades. Also, we can see that they are not a native species from the area since they were released by pet owners and by a breeding facility by accident. The fact that they are harming the Everglades' ecosystem and that they are not native species makes them an invasive species.
