Look at the picture of the African jacana. The African jacana uses its toes to spread its weight out over a large area. This can help it walk on leaves without sinking into the water. Now look at each animal. Figure out which animal has a similar adaptation. The comb-crested jacana has long, thin toes on its feet. Its feet are adapted for walking on floating leaves. The European river otter has webbed feet. Its feet are not adapted for walking on floating leaves. The European river otter uses its feet to swim.

What do these two changes have in common? boiling an egg acid rain weathering a marble statue
[ "Both are only physical changes.", "Both are caused by heating.", "Both are chemical changes.", "Both are caused by cooling." ]
C
Step 1: Think about each change. Boiling 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. Acid rain weathering a marble statue is a chemical change. The acid rain reacts with the outside of the statue and breaks it down into a different type of matter. This new matter is then washed away by the rain. Acid rain is a type of pollution. It forms when smoke from automobiles and factories mixes with water in clouds. Acid rain is a type of pollution. It forms when automobiles and factories release smoke containing sulfur or nitrogen. Some of these chemicals react with water in the atmosphere. The reaction forms droplets of water that can fall back to the ground as acid rain. 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 acid rain weathering a marble statue is not. Both are caused by cooling. Neither change is caused by cooling.

Complete the statement. Calcium is ().
[ "a compound", "an elementary substance" ]
B
You can tell whether calcium is an elementary substance or a compound by counting the number of atomic symbols in its chemical formula. An atomic symbol consists of either one capital letter or a capital letter followed by one or two lowercase letters. The chemical formula for calcium contains one atomic symbol: Ca. So, the formula tells you that calcium is composed of only one chemical element. Since calcium is composed of only one chemical element, calcium is an elementary substance.

Based on this information, what is Ringo's phenotype for the fur texture trait?
[ "straight fur", "wavy fur" ]
A
You need to determine Ringo's phenotype for the fur texture trait. First, consider the alleles in Ringo's genotype for the fur texture gene. Then, decide whether these alleles are dominant or recessive. The allele for straight fur (F) is dominant over the allele for wavy fur (f). This means F is a dominant allele, and f is a recessive allele. Ringo's genotype of Ff 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, Ringo's phenotype for the fur texture trait must be straight fur.

[ "The forces are balanced, so there is no net force on Carly.", "The forces are unbalanced, so there is a net force on Carly." ]
B
To determine if there is a net force on Carly, look at the forces: Earth's gravity is pulling Carly down with a force of 600 N. The seat of the cart is pushing Carly up with a force of 1,200 N. The forces are in opposite directions, and the forces have different magnitudes: 600 N and 1,200 N. This means that the forces are unbalanced, so there is a net force on Carly.

Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?
[ "sample A", "neither; the samples have the same temperature", "sample B" ]
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.

The total weight of 20 bars of copper is 20*90 = <<20*90=1800>>1800kgs If a copper bar weighs 90 kgs, and a steel bar weighs 20 kgs more than a copper bar, the weight of a steel bar is 90+20 = <<90+20=110>>110 kgs. If a bar of steel weighs 110 kgs, 20 bars will weigh 20*110 = 2200kgs The total weight of 20 bars of copper and steel is 2200+1800 = <<2200+1800=4000>>4000 kgs A bar of steel weighs twice the mass of a bar of tin, meaning a bar of tin weighs 110/2 = <<55=55>>55 kgs The total weight of 20 bars of tins is 55*20= <<55*20=1100>>1100 kgs The total weight of 20 bars of each metal is 4000+1100 = 5100 kgs #### 5100

Jeff bought 6 pairs of shoes and 4 jerseys for $560. Jerseys cost 1/4 price of one pair of shoes. Find the shoe's price total price.
null
480
Let X be the shoe price. The jersey's price is 1/4*X. Jeff bought 6 pairs of shoes and 4 jerseys for 6*X + 4*(1/4X) = $560. Multiplying through the parentheses produces 6X + X = $560 Combining like terms produces 7X = $560 Dividing both sides by 7 produces X = $80, so the shoe price is $80 Since Jeff bought 6 pairs of shoes, he spent 80*6 = $<<80*6=480>>480 on shoes #### 480

The particles in both samples have the same average speed, but each particle in sample B has more mass than each particle in sample A. So, the particles in sample B have a higher average kinetic energy than the particles in sample A. Because the particles in sample B have the higher average kinetic energy, sample B must have the higher temperature.
