[QUESTION]What is the expected ratio of offspring with normal wings to offspring with vestigial wings? Choose the most likely ratio.
[OPTIONS](A) 3:1 (B) 0:4 (C) 2:2 (D) 4:0 (E) 1:3
0:4
To determine how many boxes in the Punnett square represent offspring with normal wings or vestigial wings, consider whether each phenotype is the dominant or recessive allele's version of the wing type trait. The question tells you that the N allele, which is for normal wings, is dominant over the n allele, which is for vestigial wings. Normal wings is the dominant allele's version of the wing type trait. A fruit fly with the dominant version of the wing type trait must have at least one dominant allele for the wing type gene. So, offspring with normal wings must have the genotype NN or Nn. There are 0 boxes in the Punnett square with the genotype NN or Nn. Vestigial wings is the recessive allele's version of the wing type trait. A fruit fly with the recessive version of the wing type trait must have only recessive alleles for the wing type gene. So, offspring with vestigial wings must have the genotype nn. All 4 boxes in the Punnett square have the genotype nn. So, the expected ratio of offspring with normal wings to offspring with vestigial wings is 0:4. This means that, based on the Punnett square, this cross will never produce offspring with normal wings. Instead, this cross is expected to always produce offspring with vestigial wings.

[QUESTION]Complete the statement. Dichloromethane is ().
[OPTIONS](A) an elementary substance (B) a compound
a compound
Use the model to determine whether dichloromethane is an elementary substance or a compound. Step 1: Interpret the model. . Use the legend to determine the chemical element represented by each color. The colors and atomic symbols from the legend are shown in the table below. The table also includes the names of the chemical elements represented in the model. You can see from the model that a molecule of dichloromethane is composed of two hydrogen atoms, one carbon atom, and two chlorine atoms bonded together. Step 2: Determine whether the substance is an elementary substance or a compound. You know from Step 1 that dichloromethane is composed of three chemical elements: hydrogen, carbon, and chlorine.

[QUESTION]Based on this information, what is Boxer's phenotype for the coat pattern trait?
[OPTIONS](A) solid coloring (B) white spots
solid coloring
You need to determine Boxer's phenotype for the coat pattern trait. First, consider the alleles in Boxer's genotype for the coat pattern gene. Then, decide whether these alleles are dominant or recessive. The allele for solid coloring (A) is dominant over the allele for white spots (a). This means A is a dominant allele, and a is a recessive allele. Boxer's genotype of Aa has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Boxer's phenotype for the coat pattern trait must be solid coloring.

A symbol contains either one capital letter or a capital letter followed by one or two lowercase letters. The chemical formula for silane is SiH4. This formula contains two symbols: Si for silicon and H for hydrogen. So, the formula tells you that silane is made of two chemical elements bonded together. Substances made of two or more chemical elements bonded together are compounds. So, silane is a compound.

[QUESTION]Which text uses the word terribly in its traditional sense?
[OPTIONS](A) Hassan shivered terribly as he gazed at the snow-clad slope. After calming his nerves, he began his descent. (B) Hassan shivered as he gazed at the terribly steep, snowy slope. After calming his nerves, he began his descent.
Hassan shivered terribly as he gazed at the snow-clad slope. After calming his nerves, he began his descent.
The second text uses terribly in its traditional sense: in a terrible manner. Hassan shivered terribly as he gazed at the snow-clad slope. After calming his nerves, he began his descent. The first text uses terribly in its nontraditional sense: extremely; very. Hassan shivered as he gazed at the terribly steep, snowy slope. After calming his nerves, he began his descent. Most style guides recommend to use the traditional sense of the word terribly because it is considered more standard.

[QUESTION]Select the organism in the same species as the great egret.
[OPTIONS](A) Ardea alba (B) Balearica pavonina (C) Falco novaeseelandiae
Ardea alba
A great egret's scientific name is Ardea alba. Balearica pavonina does not have the same scientific name as a great egret. So, Ardea alba and Balearica pavonina are not in the same species. Ardea alba has the same scientific name as a great egret. So, these organisms are in the same species. Falco novaeseelandiae does not have the same scientific name as a great egret. So, Ardea alba and Falco novaeseelandiae are not in the same species.

[QUESTION]Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?
[OPTIONS](A) neither; the samples have the same temperature (B) sample A (C) sample B
sample A
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.

[QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[OPTIONS](A) The magnitude of the magnetic force is greater in Pair 2. (B) The magnitude of the magnetic force is the same in both pairs. (C) The magnitude of the magnetic force is greater in Pair 1.
The magnitude of the magnetic force is greater in Pair 2.
Magnet sizes affect the magnitude of the magnetic force. Imagine magnets that are the same shape and made of the same material. The larger the magnets, the greater the magnitude of the magnetic force between them. Magnet A is the same size in both pairs. But Magnet B is larger in Pair 2 than in Pair 1. So, the magnitude of the magnetic force is greater in Pair 2 than in Pair 1.
false
[QUESTION]Will these magnets attract or repel each other?
[OPTIONS](A) attract (B) repel

[QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[OPTIONS](A) The magnitude of the magnetic force is greater in Pair 2. (B) The magnitude of the magnetic force is greater in Pair 1. (C) The magnitude of the magnetic force is the same in both pairs.
The magnitude of the magnetic force is greater in Pair 1.
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. Distance affects the magnitude of the magnetic force. When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater. There is a smaller distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2.

[QUESTION]Read the following excerpt from a student essay. How can the writer best improve his or her academic voice? The belly produces acid to break down food. In patients who suffer from gastroesophageal reflux disease, more commonly known as GERD or acid reflux, the acid moves backward into the eating tube. Most often, GERD occurs because the lower esophageal sphincter, the thing at the junction of the eating tube and the belly, doesn't close the way it should or opens at the wrong time.
[OPTIONS](A) by using unbiased language (B) by avoiding first-person pronouns (C) by using more technical terms
by using more technical terms
The writer could best improve his or her academic voice by using more technical terms. For example, the writer could use technical terms for the underlined words: stomach, esophagus, and valve. The belly produces acid to break down food. In patients who suffer from gastroesophageal reflux disease, more commonly known as GERD or acid reflux, the acid moves backward into the eating tube. Most often, GERD occurs because the lower esophageal sphincter, the thing at the junction of the eating tube and the belly, doesn't close the way it should or opens at the wrong time.
