What is one way these stems help these cactus plants survive?
A. They take energy from sunlight.
B. They take minerals from soil.
C. They hold the plant in the ground.
D. They make seeds for reproduction.
Answers
Answer:
B.
Explanation:
A cactus stores water in its stem, which allows it to survive and thrive in desert-like environments. Its stem is made up of thick, spongy tissue that helps to absorb and retain large amounts of water. This stored water is then used to keep the cactus hydrated during times of drought and heat.

Which type of bond does the phrase “opposites attract” apply to best? Explain.
Answers
Answer:
The phrase "opposites attract" is true for atoms. The positively charged ion (cation) and the negatively charged ion (anion) are attracted to each other. It is this attraction, created by the transfer of electrons, that forms the ionic bond. The transfer of one electron creates a single bond.
Explanation:The phrase "opposites attract" is true for atoms. The positively charged ion (cation) and the negatively charged ion (anion) are attracted to each other. It is this attraction, created by the transfer of electrons, that forms the ionic bond. The transfer of one electron creates a single bond.
Answer:
phrase opposites attract definitely describes ionic bond because this is the only type of bonds that requires positive charge in one atom and negative charge in other atom to form an ionic compound. HOPE THIS ANSWER YOUR QUESTION!!!

A student wants to know how the number of geese in a study area affects the number of parts in their songs. She performs an experiment and records the data in a table.
Which two terms describe this type of data?
A.
Quantitative
B.
Empirical
C.
Theoretical
D.
Qualitative
Answers
The two terms that describe this type of data are Quantitative and Qualitative. Therefore, the correct options are A and D.
Data that can be measured and expressed numerically, denoting quantities or amounts, is called quantitative data. In this example, the number of geese is counted and correlated with the number of pieces in their symphony. Instead of being numerical, descriptive and categorical data are called qualitative data. In this example, it is observed and noted how many sections are in the swan songs (descriptive categories).
Therefore, the correct options are A and D.

How does an increase in altitude affect the climate?
Answers
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

In the following images, a blue circle represents an atom of one type of element, and a red square represents an atom of a second type of element. Determine which of them represent a pure substance, a homogenous mixture, and a heterogeneous mixture.
Are these in the right order?
Answers
Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.
Explanation:
Pure Substances:
There are two categories of pure substances: elements and compounds (In our case, we have a compound).
Element (e.g. the blue circles or the red squares):
An element is a fundamental substance.An element cannot become simpler than itself, even if chemical separation methods are used.Compound (e.g. the blue circles bonded together with the red squares in the middle picture):
A compound is a substance made of two or more elements in fixed proportions (i.e. One element has the same amount as the other).A compound can be made into individual elements or simpler substances using chemical methods of separation.Mixtures:
There are two categories of mixtures: homo- and hetero- genous.
Homogenous mixture:
The substances or elements are mixed to look like one single substance and cannot be told apart (e.g. When salt dissolves in water, the water still looks like water).The substances or elements are distributed evenly throughout the apparatus. The number of different types of substances or elements can vary (e.g. There is more water than salt) The substances or elements do not bond together.Heterogenous mixture:
The substances or elements are mixed and can be told apart (e.g. When oil is mixed with water, the oil is "water-hating" so it forms its own layer on the bottom, while the water forms another layer on top of the oil layer).The substances or elements are distributed where one type of substance or element is bunched up in one spot and another substance or element in another spot.The number of different types of substances or elements can vary.The substances or elements do not bond togetherThe second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.
The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.
The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.
Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.
The first image is correct, the image depicts a pure substance.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
