Answer: The correct answer to the question is option 2
If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.
Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.
Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.
Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.
This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.
<h2>Galapagos Finch </h2>
Explanation:
Darwin's finches are a classical example of an adaptive radiation
- Darwin's finches common ancestor arrived on the Galapagos about two million years ago,during the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behavior
- Changes in size and form of the beak have enabled different species to utilize different food resources such us insects, seeds, nectar from cactus flowers all driven by Darwinian selection
- From 1831 to 1836, Darwin was part of a survey expedition carried out by the ship HMS Beagle, which included stops in South America, Australia, and the southern tip of Africa
- At each of the stop, Darwin had the opportunity to study the local plants and animals
- Darwin found that nearby islands in the Galapagos had similar but nonidentical species of finches living on them,he noted that each finch species was well-suited for its environment and role
- For example species that ate large seeds tended to have large, tough beaks, while those that ate insects had thin, sharp beaks
- According to Darwin's idea, this pattern would make sense if the Galapagos Islands had long ago been populated by birds from the neighboring mainland
- On each island, the finches might have gradually adapted to local conditions (over many generations and long periods of time)
- This process could have led to the formation of one or more distinct species on each island
- Darwin developed and refined a set of ideas that could explain the patterns he had observed during his voyage
- In his book, On the Origin of Species, Darwin outlined his two key ideas: evolution and natural selection
- Natural selection which also known as “survival of the fittest,” is the more prolific reproduction of individuals with favorable traits that survive environmental change because of those traits; this leads to evolutionary change
The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ =
(for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ =
(for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

<h2>Answer:</h2>
The priority list will be like this
- Fruit Trees
- Birds
- Monkeys
- Tigers
<h2>Explanation:</h2>
In an ecosystem, producers are the first level of the food chain. And we know that plants are producers because they produce their own food. So, fruit trees will be at the beginning of the food chain. After producers comes the primary consumers. Primary consumers are animals that feed on producers. Both birds and monkeys feed on fruit trees, so they are the next in line after fruit trees. Finally, secondary consumers eat primary consumers. As tigers eat animals i.e monkeys etc so they are secondary consumers, and thus they are last on the food chain list.
