Susanna was hiking in the mountains, and she discovered an interesting, shiny rock. She wondered if this sample was actually a rock or if it might be a mineral. As she observed it more closely, she noted that it was solid and naturally occurring, with a definite chemical composition. The sample did not appear to have a crystal structure.
Could Susanna have found a mineral? Explain why or why not.
please help me out
Answer:
Yes it is a mineral
Explanation:
Susanna has found a mineral because the five characteristics of a mineral are naturally occurring solid, crystal structure, forms by inorganic process, and definite chemical composition. Everything that was listed in the question describes the fact that its a mineral.

Explain why electrical charges flow from one atom to another?
Answer: the electron from one atom will be attracted to the next atom in the direction of the positive charge the atom will jump out of its orbit in its atom into the orbit of the next atom
Explanation:
To solve this we must be knowing each and every concept related to electrical charges. Therefore, to make a neutral molecule, electrical charges flow from one atom to another.
What is electrical charges?Electrons, like protons, are bonded in an atom, although not all electrons. Electrons placed further out from the nucleus could be taken from the atom.
Whenever some electrons are taken from the atom, the amount of protons surpasses the amount of electrons leading to an electron deficit. The electrically neutral substance becomes positively charged once electrons are removed. In the opposite instance, the body can obtain electrons from an external source. In this instance, the body's electron count rises resulting in it becoming negatively charged.
Therefore, to make a neutral molecule, electrical charges flow from one atom to another.

Why New York City and Los Angeles do not experience sunrise at the same time?
Answer:
December solstice sunrise comes at the same time for St. ... But St. Augustine has an hour more of daylight than New York. ... Look above at the simulated view of Earth as the sun is rising ...
Answer:
The different sunrise and sunset times are caused by the cities being at different locations within a time zone. This causes both cities to have a different time at which solar noon occurs, and so will shift sunrise and sunset times either forward or backwards
As to daylight hours, theoretically they should be the same at both locations. However, in real life, the amount of daylight hours at both locations is slightly different because of when (solar time) the solstice occurs.
In two to four sentences, explain how you ranked the plants from most desirable to least desirable. Be sure to cite evidence from the data to support your rankings.
Answer:My plant rankings could protect the dunes because my plant rankings show most desirable plants and least desirable plants. Many people could use my plant rankings for saving dunes because when you look at the ranking and if you are trying to save a dune you would use the most desirable plants out of the seven plants.
Explanation:
Plant rankings, that include the best and least desired plants, might help to protect the dunes.
What do you mean by Dunes?A dune is a sand mound that the wind has created, typically near a beach or in a desert.
When wind drives sand into a protected region behind an obstruction, dunes are created. Sand particles build up, creating dunes. There is a slip face and a windward side to every dun.
Since you would use the top-ranked plants from the list of seven if you were attempting to save a dune, many people may benefit from using my plant rankings.
Sand that is carried inland and dumped above the high tide mark forms coastal sand dunes.
This is then contained by seaside objects, allowing specialised dune-building grasses to develop and ascend through further layers of sand.

Which of the following is the best example of erosion?
a Sediment piling up at the mouth of a river
b Plant roots growing through concrete and splitting it
c Waves carrying sand away from a beach
d A large rock splitting into pieces because of ice
Answer:
Option C
Explanation:
Remember erosion is the process of moving sediments to one location to another. In this case waves moving sand away from the beach and to another location is erosion which means your answer is option C. It's not option B because plant roots breaking apart concert is a example of weathering, and the same goes for option D.

Which of the following is true for compounds?
a) They can be created by chemical reactions.
b) They can be separated into their component elements through physical means.
c) They all have the same properties regardless of their elemental composition.
d) They can consist of no more than two types of elements.
Answer:
Answer: The correct option is that the compounds are created by chemical reactions.
Explanation:
Option 1: Elements combine chemically in a specific ratio to form compounds. They can't be separated by physical methods like filtration. For example, is made up 2 H-atoms and 1 O-atom. When we filter water through normal filtration, we do not obtain H-atom and O-atom separately, but we get combined form of hydrogen and oxygen atom that is .
Option 2: Compounds are formed when two or more elements combine chemically.
Option 3: Compounds can have more than two types of elements. For example, In , 3 elements are present - Calcium(Ca), Carbon(C), Oxygen(O).
Option 4: Compounds formed have different properties from one another. There can be difference in physical properties as well as chemical properties. For example, (water) and (calcium carbonate) are two compounds. Water is present in liquid state and calcium carbonate is present in solid state. Hence, it showed that all the compounds cannot have same properties
The chemical compound can be created by chemical reactions. Therefore, option (A) is correct.
What is a Chemical compound?A chemical compound can be defined as a combination of two or more either similar or dissimilar chemical elements. A chemical compound is composed of many identical molecules containing atoms from more than one element held together by chemical bonds.
A molecule containing atoms of one element is therefore not a compound. A compound can be converted into a different substance by a chemical reaction, which can involve interactions with other substances. The chemical bonds between atoms may be broken or form new bonds.
Molecular compounds have covalent bonds, ionic compounds have ionic bonds, Metallic compounds have metallic bonds and coordination complexes have coordinated covalent bonds.
Therefore, compounds can be created by chemical reactions. They have different properties regardless of their elemental composition.

Answer:
Seeds
Explanation:
Took the test
An angiosperm is a plant that has flowers and fruits with seed in them.
What is an angiosperm ?Angiosperms are plants that produce flowers and seeds in the form of fruits. With approximately 300,000 species, they are the kingdom Plantae's largest and most diverse group. Angiosperms account for roughly 80% of all known living green plants.
Vascular plants are angiosperms. They are made up of stems, roots, and leaves. Angiosperm seeds, unlike gymnosperm seeds such as conifers and cycads, are found in a flower. Angiosperm eggs are fertilized and grow into seeds in an ovary, which is usually found in a flower.
Another similarity is their ability to produce secondary growth. Angiosperms produce flowers and fruit with seeds within ovaries, whereas Gymnosperms produce seeds in cones.
Thus, An angiosperm is a plant that has flowers and fruits with seed in them.
