A common characteristic about deserts is large fluctuations in temperatures between day and night. Question 8 options: True False
PLZZZZZ HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer: The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night. The daytime temperature averages 38°C while in some deserts it can get down to -4°C at night. The temperature also varies greatly depending on the location of the desert.

Explanation: True

The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night.

The daytime temperature averages 38°C while in some deserts it can get down to -4°C at night. The temperature also varies greatly depending on the location of the desert.

The driest biomes are the desert ones. In actuality, a desert's primary distinguishing feature is how little rain it gets. Compared to rainforests, which receive over 2,000 mm annually, most deserts receive less than 300 mm.

Hence, the desert only receives 10% of the rainfall that a rainforest does. Because the air is so dry and heat escapes so quickly at night, the temperature in the desert can vary significantly from day to night.

Therefore, The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night.

Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks.
A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.

B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.

C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.

D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.

E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.
