According to the author, what is the main reason for the decrease in trillium in the forest?
What evidence does she give to support her claim?
Answer:
The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard, and trillium.
The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium.
What is trillium?Trillium is a type of flowering plant that grows best in a partly-shaded, deciduous woodland habitat and along wet areas in the forest.
Deer is a herbivorous animals that feeds on the buds, blooms, berries, leaves, and even the stems of trillium.
Therefore, the main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium.

Answer:
This process, called satiation, increases the chance that cicadas will escape being eaten for long enough to survive and reproduce. ... It comes from a phenomenon known as the Allee Effect: the smaller a population gets, the less likely its members are to find one another and reproduce.
alphrinaelric4264 avatar
The seven periodical cicada species are so named because, in any one location, all of the members of the population are developmentally synchronized—they emerge as adults all at once in the same year. This periodicity is especially remarkable because their lifecycles are so long—13 or 17 years.

Evaporation happens in the Dead Sea and other bodies of salt water (like the oceans) as part of the water cycle. What fuels evaporation in bodies of salt water?
Answer:
Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation. A state of saturation exists when these two process rates are equal, at which point the relative humidity of the air is 100 percent. Condensation, the opposite of evaporation, occurs when saturated air is cooled below the dew point (the temperature to which air must be cooled at constant pressure for it to become fully saturated with water), such as on the outside of a glass of ice water. In fact, the process of evaporation removes heat from the environment, which is why water evaporating from your skin cools you.
Explanation:
Solar energy fuels evaporation in bodies of salt water. Evaporation happens in the Dead Sea and other bodies of salt water (like the oceans) as part of the water cycle.
What is evaporation?Evaporation in bodies of salt water is fueled by solar energy from the sun. The sun's heat causes the water molecules in the surface of the salt water to gain energy and become more active. As the water molecules become more active, they gain enough energy to break free from the liquid and become water vapor, which rises into the atmosphere. This process is known as evaporation.
In bodies of salt water, the process of evaporation leaves behind salt and other minerals, which increases the salinity of the water. The high salinity of the Dead Sea and other saltwater bodies can also affect the evaporation rate, as the presence of salt can make it more difficult for water molecules to escape from the surface.

The following table shows the currently accepted half-life values for four parent isotopes.
Parent Isotope Currently Accepted Half-Life Values
Uranium-238 4.5 billion years
Uranium-235 704 million years
Thorium-232 14.0 billion years
Rubidium-87 48.8 billion years
Potassium-40 1.25 billion years
Samarium-147 106 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope?
Rubidium-87
Thorium-232
Uranium-235
Uranium-238
Answer:
The amount of substance present in a certain sample can be calculated through the equation,
A(t) = A(o)(0.5)^(t/h)
where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.
For a substance to at most 50% of the original amount, we get the half-life value.
At/Ao = 0.5 = 0.5^(4.5/h)
h = 4.5 billion.
ok the answers are simple:
Parent Isotope Currently Accepted Half-Life Values: is the first one uranium-238 4.5 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope: uranium- 238
