The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.

Imagine that you are a leaf on a plant, and you realize that you are running low on supplies to do your job. You decide to text the roots to set up a delivery. Write a text message conversation between the leaf and the roots that discusses and arranges this delivery.
Answer:
Leaf: Hey Roots, this is Leaf. I'm running low on supplies here. Can you send some over?
Roots: Hey Leaf, of course. What kind of supplies do you need?
Leaf: I need more water and nutrients. Can you send some my way?
Roots: Sure thing, we'll get on it right away. How much do you need?
Leaf: Just enough to keep me going for a few more days. Can you also send some sunlight my way?
Roots: Sorry, we can't help with that one. But we'll make sure to send enough water and nutrients to help you out.
Leaf: Thanks, Roots. You're the best. Let me know when the delivery is on its way.
Roots: Will do, Leaf. Hang in there. Delivery should be there soon.
Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent
If a 3.0 picogram (pg) sample of curium-245 has a half-life of 8500 years, which conclusion can be drawn?
A: The curium-245 sample must have an age of at least 8500 years.
B: The curium-245 sample must have an age of less than 8500 years.
C: The curium-245 sample will have a mass of about 6.0 pg after 8500 years.
D: The curium-245 sample will have a mass of about 1.5 pg after 8500 years.
Answer:
its A
Explanation:
If a 3.0 (pg) sample of curium-245 has a half-life of 8500 years, then the conclusion which can be drawn is the curium-245 sample will have a mass of about 1.5 pg after 8500 years
What is half life time?Half life time is that time after which initial concentration of reactant becomes half of the initial.
Given that initial concentration of curium-245 = 3pg
After half life time concentration of curium-245 = 1.5pg
The curium-245 sample must have an age of at least 8500 years is wrong as given time is the half life time.The curium-245 sample must have an age of less than 8500 years is wrong as given time is the half life time.The curium-245 sample will have a mass of about 6.0 pg after 8500 years is alo wrong as left sample shold be half of the initial.Hence, the curium-245 sample will have a mass of about 1.5 pg after 8500 years is the conclusion.

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION
Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.
The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.
Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

The corn crop in an area is prone to infestation by larvae from moths that feed on the cornstalks and ears of corn. The techniques used by two farmers to protect the corn crop are described below.
Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.
Which technique is likely to have less of an impact on the environment?
Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

Answer: When one object is rubbed against the another, static electricity can be created because the rubbing creates a negative charge, carried by electrons
Explanation:
When we rub a balloon on our head, it causes opposite static charges both on hair and balloon. When the balloon is pulled slowly away from our head, we can see these two opposite static charges attracting one another and making our hair stand up.
On rubbing a balloon on wool, the electrons move from the wool to the balloon's surface. The rubbed part of the balloon has a negative charge. Balloons, the electrical insulators, resist electric charges flowing through them. So only a part of the balloon has negative charge (where the wool is rubbed) and other places remain neutral.
When a balloon is rubbed to wall, it will be attracted to the wall. The charge is not immediately discharged as the wall is an electrical insulator.
When we rub the balloon against metal, the extra electrons in the balloon quickly leave the balloon and move into the metal so the balloon is no longer attracted and does not adhere.

3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.

What force causes the measurement of weight?
Answer:
Gravity
Explanation:
Gravity is what causes you to weigh more or less.
What is gravity? Gravity is the force that pulls things together. Larger things with larger masses have more gravity. When you are on Earth, you would weigh more than on the moon, about 6 times more, in fact, because the gravity on Earth is 6 times stronger.
