An angiosperm is a plant that has flowers and fruits with _________
in them.
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.

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.

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.

If energy is released or absorbed during a chemical reaction, where is the energy going?
Answer:

Which material absorbs the MOST solar radiation? a.Sand b.Grassy Field C.Fresh snow d.Forest
Forest absorbs most of the solar radiation. Therefore, option (d) is correct.
What are solar radiations?Solar radiation can be described as electromagnetic waves coming from the sun and comes in three major types: visible light, infrared light, and ultraviolet light.
The electromagnetic spectrum has seven different types of light, listed from lowest frequency to highest: radio waves, microwaves, IR light, visible light, UV light, X-rays, and gamma rays. Solar radiation is light from the sun that can be categorized by its frequency and wavelength.
Solar irradiance can be described as the power per unit area received from the Sun in the form of radiation in the wavelength range and is measured in watts per square meter.
This may be measured in space or at the surface of the earth after atmospheric absorption and scattering. The forests have plants and trees which absorb the most solar radiation.
