Question: [QUESTION]Which bird's beak is also adapted to get nectar out of long flowers?
Solution: Look at the picture of the rufous hummingbird.
The rufous hummingbird has a long, thin beak. Its beak is adapted to get nectar out of long flowers. The rufous hummingbird's long, thin beak can reach deep into the flowers.
Now look at each bird. Figure out which bird has a similar adaptation.
The malachite sunbird has a long, thin beak. Its beak is adapted to get nectar out of long flowers.
The roseate spoonbill has a long spoon-shaped beak. Its beak is not adapted to get nectar out of long flowers. The roseate spoonbill uses its beak to filter through mud for invertebrates and small fish.

Question: [QUESTION]What is the expected ratio of offspring with curly fur to offspring with straight fur? Choose the most likely ratio.
Solution: To determine how many boxes in the Punnett square represent offspring with curly fur or straight fur, consider whether each phenotype is the dominant or recessive allele's version of the fur type trait. The question tells you that the F allele, which is for straight fur, is dominant over the f allele, which is for curly fur.
Curly fur is the recessive allele's version of the fur type trait. A cat with the recessive version of the fur type trait must have only recessive alleles for the fur type gene. So, offspring with curly fur must have the genotype ff.
There are 2 boxes in the Punnett square with the genotype ff. These boxes are highlighted below.
Straight fur is the dominant allele's version of the fur type trait. A cat with the dominant version of the fur type trait must have at least one dominant allele for the fur type gene. So, offspring with straight fur must have the genotype FF or Ff.
There are 2 boxes in the Punnett square with the genotype FF or Ff. These boxes are highlighted below.
So, the expected ratio of offspring with curly fur to offspring with straight fur is 2:2. This means that, on average, this cross will produce 2 offspring with curly fur for every 2 offspring with straight fur.

Question: [QUESTION]What is the expected ratio of offspring with bumpy fruit to offspring with smooth fruit? Choose the most likely ratio.
Solution: To determine how many boxes in the Punnett square represent offspring with bumpy fruit or smooth fruit, consider whether each phenotype is the dominant or recessive allele's version of the fruit texture trait. The question tells you that the F allele, which is for bumpy fruit, is dominant over the f allele, which is for smooth fruit.
Bumpy fruit is the dominant allele's version of the fruit texture trait. A cucumber plant with the dominant version of the fruit texture trait must have at least one dominant allele for the fruit texture gene. So, offspring with bumpy fruit must have the genotype FF or Ff.
There are 0 boxes in the Punnett square with the genotype FF or Ff.
Smooth fruit is the recessive allele's version of the fruit texture trait. A cucumber plant with the recessive version of the fruit texture trait must have only recessive alleles for the fruit texture gene. So, offspring with smooth fruit must have the genotype ff.
All 4 boxes in the Punnett square have the genotype ff.
So, the expected ratio of offspring with bumpy fruit to offspring with smooth fruit is 0:4. This means that, based on the Punnett square, this cross will never produce offspring with bumpy fruit. Instead, this cross is expected to always produce offspring with smooth fruit.

Question: [QUESTION]What is the source of the allusion in the sentence below?
Kenji described the situation he was facing with his boss as a catch-22.
Solution: The source of the allusion catch-22 is literature.
Joseph Heller coined the term "catch-22" in his 1961 novel of the same name. In the novel, if an army pilot wants to avoid dangerous missions, he must be deemed mentally unfit; however, his desire to stay safe proves his sanity, so he can never be excused from a mission. Heller called this sort of predicament or dilemma a catch-22.
The allusion catch-22 means a no-win situation.

Question: [QUESTION]Select the elementary substance.
Solution: Look at the chemical formula for each substance, and count the number of symbols in the formula. Then, decide if the substance is an elementary substance. The chemical formula for boron trichloride contains two symbols: B for boron and Cl for chlorine. So, boron trichloride is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, boron trichloride is a compound, not an elementary substance. The chemical formula for benzene contains two symbols: C for carbon and H for hydrogen. So, benzene is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, benzene is a compound, not an elementary substance. The chemical formula for silicon contains one symbol: Si. So, silicon is made of one chemical element. Substances that are made of one chemical element are elementary substances. So, silicon is an elementary substance.

Question: [QUESTION]What do these two changes have in common?
filtering air to remove dust and pollen
a crayon melting in the sun
Solution: Step 1: Think about each change.
Filtering air to remove dust and pollen is a physical change. The air flows through the filter, and the pollen and dust stay behind. This separates the mixture of air, pollen, and dust. But separating a mixture does not form a different type of matter.
A crayon melting in the sun is a change of state. So, it is a physical change. The crayon changes state from solid to liquid. The crayon is still made of wax, even after it melts.

Both are only physical changes.
Both changes are physical changes. No new matter is created.
Both are chemical changes.

Question: [QUESTION]Select the elementary substance.
Solution: Look at the chemical formula for each substance, and count the number of symbols in the formula. Then, decide if the substance is an elementary substance. The chemical formula for ammonia contains two symbols: N for nitrogen and H for hydrogen. So, ammonia is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, ammonia is a compound, not an elementary substance. The chemical formula for bromomethane contains three symbols: C for carbon, H for hydrogen, and Br for bromine. So, bromomethane is made of three chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, bromomethane is a compound, not an elementary substance. The chemical formula for gold contains one symbol: Au. So, gold is made of one chemical element. Substances that are made of one chemical element are elementary substances. So, gold is an elementary substance.
