The medium ground finch lives on the Galapagos Islands. Birds with beaks of all sizes were originally part of this population. T

he finches are seed eaters. The types of food available for them to eat depends on the weather. During wet years, there is a large variety of food. During dry years, there is less food, and large, tough seeds are more abundant than small seeds. After a long drought, researchers noticed certain differences in the population of medium ground finches living compared to those who lived before the drought. What was different about the finches after the drought?

Answer:

Finches after drought had stronger and larger beaks to demolish the harder and larger seeds that the drought brought, a difference from those that lived in wet times that had smaller, pointy beaks to eat smaller seeds.

Explanation:

This is called the theory of animal evolution, where animals adapt according to the environment, this theory was just analyzed by this species of animals and many more on the island of Galapagos by Darwin.

What I also approve of as that animal that survives a certain environment is the one that is considered most suitable to live in that place.

Fifteen grams of a liquid plastic are frozen in a physical change that increases the volume. What can be known about the plastic
Brrunno [24]
I think the correct answer would be the third option. From the physical change that happened, we can only tell that the mass of the plastic would be still the same and would weigh 15 grams. This is in accordance with the Law of conservation of mass where it states that mass cannot be destroyed or created. So, since it is only a physical change that happens the substance itself would still be the same and it is only the form that is changed, it would still have the same mass. However, with the change, the volume is changed and is said to increase which means it would greatly affect the density. Increasing the volume would result to a decrease in density.

two solutions are made by mixing sugar and enough water to make a 1 liter solution. one contains 5% sugar and the other contains
Free_Kalibri [48]

Based on their percent concentration, the 5% sugar solution contains more water.

<h3>What is the concertation of a solution?</h3>

The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.

Concentration of solutions can be expressed as either:

  • molar concentration
  • mass concentration
  • percentage concentration

The concentration of the sugar solutions are given as percent concentration.

The 5% sugar solution contains 5% sugar and 95% water

The 10% sugar solution contains 10% sugar and 90% water.

Therefore, the 5% sugar solution contains more water.

Question 47
olasank [31]

Answer:

84.27 g

Explanation:

<em>How many grams of hydrogen are in 10.45 moles of C₃H₈?</em>

Step 1: Calculate the moles of atoms of hydrogen

The molar ratio of C₃H₈ to H is 1:8.

10.45 mol C₃H₈ × 8 mol H/ 1mol C₃H₈ = 83.60 mol H

Step 2: Calculate the mass corresponding to 83.60 moles of hydrogen

The molar mass of hydrogen is 1.008 g/mol.

83.60 mol × 1.008 g/mol = 84.27 g
