The words stem, end, every, and fleck share a vowel sound. | TheMrguiller/ScienceQA |
Question: [QUESTION]Based on this information, what is Roy's phenotype for the Marfan syndrome trait?
Solution: Roy's genotype for the Marfan syndrome gene is mm. Roy's genotype of mm has only m alleles. The m allele is for not having Marfan syndrome. So, Roy's phenotype for the Marfan syndrome trait must be not having Marfan syndrome.
To check this answer, consider whether Roy's alleles are dominant or recessive. The allele for having Marfan syndrome (M) is dominant over the allele for not having Marfan syndrome (m). This means M is a dominant allele, and m is a recessive allele.
Roy's genotype of mm has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, Roy's phenotype for the Marfan syndrome trait must be not having Marfan syndrome. | TheMrguiller/ScienceQA |

Question: [QUESTION]Select the organism in the same genus as the Steller's sea eagle.
Solution: A Steller's sea eagle's scientific name is Haliaeetus pelagicus. The first word of its scientific name is Haliaeetus.
Haliaeetus leucocephalus is in the genus Haliaeetus. The first word of its scientific name is Haliaeetus. So, Haliaeetus leucocephalus and Haliaeetus pelagicus are in the same genus.
Tyto alba is in the genus Tyto. The first word of its scientific name is Tyto. So, Tyto alba and Haliaeetus pelagicus are not in the same genus.
Alopias pelagicus and Haliaeetus pelagicus are not in the same genus.
These organisms are not in the same genus, but part of their scientific names is the same. Alopias pelagicus and Haliaeetus pelagicus have the same species name within their genus, pelagicus. But the first words of their scientific names are different. Alopias pelagicus is in the genus Alopias, and Haliaeetus pelagicus is in the genus Haliaeetus. | TheMrguiller/ScienceQA |
Question: [QUESTION]Complete the statement.
During this chemical reaction, the air around the reaction becomes ().
Solution: To determine whether the air around the reaction becomes warmer or colder, look for the text that describes the movement of thermal energy during the reaction.The most common type of cement in the world is Portland cement, named after an area of England that has a lot of limestone. Limestone is made up mostly of calcium carbonate (CaCO3). When calcium carbonate is heated, it breaks down into carbon dioxide (CO2) and calcium oxide (CaO), the main ingredient in Portland cement. During this reaction, thermal energy is taken in from the surroundings and converted to chemical energy.The underlined text tells you that thermal energy is taken in from the surroundings. Because thermal energy moves out of the surroundings and into the reaction, the temperature of the surroundings decreases.The surroundings include the air around the reaction. So, the air around the reaction becomes colder. | TheMrguiller/ScienceQA |
Question: [QUESTION]Is the wind through a tree a solid, a liquid, or a gas?

Question: [QUESTION]What do these two changes have in common?
a piece of pizza rotting in a trashcan
cooking an egg
Solution: Step 1: Think about each change.
A piece of pizza rotting is a chemical change. The matter in the pizza breaks down and slowly turns into a different type of matter.
Cooking an egg is a chemical change. The heat causes the matter in the egg to change. Cooked eggs and raw eggs are made of different types of matter.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are chemical changes. They are not physical changes.
Both are chemical changes.
Both changes are chemical changes. The type of matter before and after each change is different.
Both are caused by heating.
Cooking is caused by heating. But a piece of pizza rotting is not.
Both are caused by cooling.
Neither change is caused by cooling. | TheMrguiller/ScienceQA |
Question: [QUESTION]Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?
Solution: The particles in both samples have the same average speed, but each particle in sample A has more mass than each particle in sample B. So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
Because the particles in sample A have the higher average kinetic energy, sample A must have the higher temperature. | TheMrguiller/ScienceQA |
Question: [QUESTION]What is the source of the allusion in the sentence below?
Red velvet cupcakes were Sasha's Achilles's heel when she was trying to eat more healthily.
Solution: The source of the allusion Achilles's heel is Greek mythology.
In Greek mythology, Achilles's mother dips him in a river that protects his body wherever it touches. His heel does not get wet, so it is the one part of his body left unprotected. During the Trojan War, an arrow hits Achilles in the heel and kills him.
The allusion Achilles's heel means a sole weakness. | TheMrguiller/ScienceQA |

The idiom a lot on her plate suggests that Layla has many responsibilities. If you have a lot on your plate, you are busy with many different obligations. | TheMrguiller/ScienceQA |
Question: [QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
Solution: The magnets in Pair 2 attract. The magnets in Pair 1 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force.
Both magnet sizes and distance affect the magnitude of the magnetic force. The sizes of the magnets in Pair 1 are the same as in Pair 2. The distance between the magnets is also the same.
So, the magnitude of the magnetic force is the same in both pairs. | TheMrguiller/ScienceQA |
Question: [QUESTION]Complete the sentence so that it uses personification.
