Answer:
8.43 ( C )
Explanation:
GIVEN data:
hardness = 2.5
mass = 29.5 g
volume = 3.5 cm^3
specific gravity = density of mineral / density of water
density of mineral = mass / volume = 29.5 / 3.5 = 8.43
density of water = 1
therefore specific gravity of Mineral " A " = 8.43 / 1 = 8.43
Note : The density of the Mineral is the same as the specific gravity of the mineral.

Which statements best describe the cladogram? Select three options.
Reptiles are the most primitive.
Birds and reptiles are most closely related.
Frogs are more closely related to fish than birds.
Frogs are more closely related to birds than fish.
Fish are the most primitive.
Answer:
The correct options are:
B, C and E.
Explanation:
The cladogram is a diagram which is used to demonstrate the theoretical relationship between groups of animals, called a phylogeny.
Phylogeny examines the relationship between different groups of organisms and their evolutionary development. It tries to trace the evolutionary history of all life on the planet.
Phylogeny stands on the assumption that all organisms share a common origin.
Thus a cladogram is used as a visual aid by a scientist studying phylogenetic relationships to examine the various organisms being and how they relate to each other.

Explanation:
Which flowchart best explains how a change in ocean temperature, such as
occurs during El Niño or La Niña, could affect weather in another part of the
world?
O A. Ocean - Weather - Clouds - Wind
O B. Coriolis effect - Atmosphere - Wind - Ocean
O C. Weather - Atmosphere Wind – Ocean
O D. Ocean - Atmosphere -
Wind - Weather
Answer:
D. Ocean - Atmosphere - Wind - Weather
Explanation:
The El Nino (warm) and La Nina (cool) are the opposing phases of climatic patterns in the tropical pacific ocean and take place every 3 to 7 years. Combined they are called ENSO. First, in the El Nino ocean temperatures in the eastern tropical pacific ocean rise above average and this leads to rainfall over Indonesia and storms in central pacific. This rising air increases the air motion and leads to dryness and high surface pressure during the La Nina phase this condition gets reversed. During the El Nino, the northwestern pacific tends to be warmers and the southern tier of California tends to be cooler and wetter. These surface temperatures are caused and changed by the help of trade winds. These blows from east to west along the pacific ocean. These phenomena thus influenced the weather along the western and the eastern pacific ocean.How do scientists count a species population?
A. Add up the individuals who come into an area because of
reproduction or immigration,
B. Add up the individuals who leave an area or die,
C. Add up the biodiversity in an area,
D. Add
up
the individuals who come into an area and subtract those
who leave the area,
Answer: D
Explanation: :)
The correct answer is to add up the individuals who leave an area or die, which is option b, as when scientists count a species population, they typically use a method known as population census or population sampling.
Sampling is a method where scientists select a representative sample area within the species' habitat or range. This sample area should be large enough to be representative of the entire population but manageable for counting and data collection. Scientists then count the number of individuals within the sample area. Once the number of individuals within the sample area is determined, scientists use statistical methods to extrapolate this information to estimate the total population size.

Which of the layers of the Earth has the following characteristics? i. It is solid and extremely hot. ii. It is the innermost layer of the Earth. iii. It is around 800 miles thick. A. outer core B. inner core C. crust D. mantle Please select the best answer from the choices provided A B C D
Answer:
b. inner core
Explanation:
To solve this problem let's start by listing the information given. This will help us find which option best fits the characteristics provided to find the correct answer.
characteristics of mystery layer:
i. it is solid and extremely hot
ii. it is the innermost layer of the Earth
iii. it is around 800 miles thick
Now let's go through each option to determine which best matches the characteristics.
option a
outer core
The first characteristic of the mystery layer is 'it is solid and extremely hot.' The outer core of the earth, however, is a fluid layer. Therefore, this option cannot be correct.
option b
inner core
The inner core is a solid 'ball' and is about 10,800°F. It is also the inner, or last layer, of the earth and is around 800 miles thick. Therefore, it matches all characteristics of the mystery layer so, this must be the correct answer. If you would like to be sure, I also reviewed the last two options below.
option c
crust
Because the crust is the outermost layer of the planet, it does not match the second characteristic of the mystery layer. Therefore, this cannot be the correct answer to the question.
option d
mantle
Although the mantle does match the first characteristic, it does not match the second characteristic, which requires the layer to be the innermost layer of the earth. The mantle is one of the outer layers of the earth.
Now that all options are reviewed, we have determined the best solution to the problem. The correct answer to this question is b. inner core.
Answer:
inner core
Explanation:
To solve this problem let's start by listing the information given. This will help us find which option best fits the characteristics provided to find the correct answer.

Often in courses you will need to store and retrieve files within folders. What is the name of the FOLDER in which the file named "script" is contained?
Answer:
The folder name is "script".
Explanation:
The file called "script" contains a type of instruction that computer systems must follow to allow software to do the work it was designed for. For example, let's say that you have software that should do monthly budget calculations, the "script" will present instructions showing the steps that your computer must follow to make these calculations.
The folder where the "scripts" are saved can have any name, but it is important that it has a simple name and easy to identify what the folder wants, the best option however, is to name it as "script".

What would happen in a rainforest climate if he earth stops rotating daily? What would happen in a tundra climate if he earth stops rotating daily?
The consequences caused if the planet earth stopped spinning are very controversial and no scientist has come to a conclusion of what would actually happen. However, it is known that the consequences would be disastrous and both tropical forests and tundras would suffer a strong impact and would cease to exist over time.
Both the rainforest and the tundra would cease to exist in a situation like this. This is because areas are very influenced by the climate and the factors that each climate imposes for their survival.
First, if the earth stopped spinning, the world would be extremely hot on one side and extremely cold on the other. The tundra that was on the side of the earth that had access to the sun would not be able to form, whereas the tundra that was on the side of the earth that did not have access to the sun would be totally consumed by the animals that would live in that environment and that have no other options.
The tropical forest, on the other hand, if it were next to the sun, would suffer from the extreme temperature that would be caused, in addition to the evaporation of their bodies of water and all the humidity of that environment. In addition, extreme temperature could cause natural fires that would be extremely destructive. If the rainforest were on the side that has no access to the sun, the trees would die, since the presence of sunlight is essential for photosynthesis.
Select the best match between the PROCESSES that create new topography and the FORMS that you are exposed to through media. This matching question all relates to volcanic features in Hawaii. Group of answer choices Vog combines the words volcanic and smog. Vog is air pollution produced when sulfur dioxide and other gases and particulates are erupted into the atmosphere. Interactions with moisture and sunlight tends to make the vog worse. In the case of the May 2018 eruptions of Kilauea, the vog is being transported by the dominant winds. Please study this NASA data Links to an external site. about vog movement and match it to the best answer.
Answer:
According to NASA, the vog moves in south-west direction.
Explanation:
On May 2018 eruptions of Kilauea, the vog is being transported by the dominant winds in the direction where wind is blowing. On the basis of information provided by NASA, the vog which is emitted from the volcano moves in south-west direction by trade winds. The vog moves in south-west direction because the winds were also moving in that direction and as a result the vog is dispersed on a large area.
Find the equation of the line that is parallel to y=2x and goes through the point (-2, 3 )
Answer:
y=2x+7
Explanation:
Y=mx+b
y=2x has a rise of 2 and a run of 1 ( goes up two and over one)
to find use the change in slope formula (y2-y1)/(x2-x1) that are on the line
I used (0,0), (1,2)
(2-0)/(1-0)
2/1
your change in slope is 2
To find the y-intercept which is b you have to enter the point (-2,3) into the original equation
y=2x+b
3=2(-2)+b
3=-4+b
3+4=b
7=b
therefore your final equation is y=2x+7

Which activity could best prepare residents along the Mediterranean coast to reduce the loss of human life during a future tsunami?
Answer:
The best thing that inhabitants can do to reduce loss of life during a tsunami is to engage in an evacuation drill in some areas that are particularly vulnerable to earthquakes, and therefore, tsunamis. More specifically, these areas would be low lying neighborhoods that border the coasts.
Geographically speaking, Southern Italy and Greece are the most seismic regions of the Mediterranean, so evacuation drills should ideally be held there.

Which of the following methods can be used by officials to solve the problem of water pollution? Dispose chemical wastes in dustbins. Stop droughts and floods. Increase the number of factories. Use scientific solutions.
Answer:
"Dispose of chemical wastes in dustbins"
Explanation:
Chemical wastes often end up in rivers or streams. By disposing chemicals wastes in dustbins, this would ensure the waste does not end up in the water. However, the waste would need to be properly disposed of using proper containers for the waste.
Answer:
A. Dispose of chemical wastes in dustbins
Explanation:
B is an obvious answer, but it only presents what has to be done, not a way to solve the problem. C is the exact opposite of what should be done to solve the problem of pollution. D is very vague, and doesn't detail any specific scientific solution. A is the answer!
