From 20,000 to 5,000 years ago, humans living in Northern Europe developed a lighter skin color. Evolution theory explains this as an increase in the production of vitamin D from sunshine.
The change in skin color can be attributed to the need for increased vitamin D synthesis in regions with lower levels of sunlight. In Northern Europe, sunlight is less abundant compared to regions closer to the equator, resulting in reduced UV radiation exposure. Since UV radiation plays a crucial role in the production of vitamin D in the body, populations in Northern Europe needed to adapt to optimize their vitamin D synthesis.
Through the process of natural selection, individuals with lighter skin had an advantage as they were able to synthesize more vitamin D from the limited sunlight available. This adaptation conferred a survival advantage and increased reproductive success for those with lighter skin, leading to the spread of genes associated with lighter pigmentation over generations.
Therefore, the evolutionary explanation for the development of lighter skin color in humans living in Northern Europe during this period is primarily related to the need for increased vitamin D production due to reduced sunlight availability.

The wrong statement about mountain and valley breezes is that valley breezes usually reach their maximum strength in the early morning, cloudiness, showers, and even thunderstorms are common over mountains in the morning.
The correct option is (b).
Valley breezes typically reach their maximum strength in the afternoon, not the early morning. During the day, the sun heats the valley's air, causing it to rise and creating a pressure gradient. This gradient leads to the development of the valley breeze, which flows from the cooler mountainsides towards the warmer valley. As a result, cloudiness, showers, and thunderstorms are more likely to occur in the afternoon over mountains, as the rising air can trigger convective processes that lead to the formation of clouds and precipitation. In the early morning, however, the air is usually more stable, and the valley breeze is not at its peak strength.

estimate the energy coming to earth from the sun each second. the radius of earth is about 6400 km .
The energy that comes from the sun to Earth each second is vast and is referred to as solar irradiance. The energy received from the sun can be calculated by using the formula given below:E = (L/4πd²)Where E is the irradiance in watts per square meter, L is the solar luminosity (total energy output) in watts, and d is the distance from the sun to the Earth.
The luminosity of the sun is 3.828 x 10²⁶ watts, and the average distance between the Earth and the sun is approximately 149.6 x 10⁶ km. Therefore, the distance between the Earth and the sun can be converted to meters by multiplying it by 1000 to get the correct units. Therefore, we can write d = 149.6 x 10⁶ x 1000 m = 1.496 x 10¹¹ mThe energy that comes to the Earth from the sun is therefore given by:E = (3.828 x 10²⁶ W/4π(1.496 x 10¹¹ m)²) = 1361 W/m²Now, we can calculate the total energy that comes from the sun to the Earth each second by multiplying this value by the area of the Earth:A = 4πr²A = 4π(6,400,000 m)²A = 5.124 x 10¹⁴ m²Therefore, the total energy coming to Earth from the sun each second is:1361 W/m² x 5.124 x 10¹⁴ m² = 6.96 x 10¹⁷ W (approx.)Therefore, about 6.96 x 10¹⁷ joules of energy come to Earth from the sun each second.

Assume that 25% of the area is under irrigated. a) 3.427 inches b) 3.658 inches c) 4.473 inches d) 3.815 inches e) 4.254 inches
The amount of water stored for ET in this border strip irrigation system is approximately 0.762 inches. Among the given options, the closest answer is d) 3.815 inches.
To calculate the amount of water stored for evapotranspiration (ET) in this border strip irrigation system, we need to consider the irrigation depth and the depletion uniformity (DU).
Given that the system applies 5.6 inches of water with a DU of 0.68, we can calculate the effective irrigation depth:
Effective irrigation depth = Applied irrigation depth × DU
Effective irrigation depth = 5.6 inches × 0.68
Effective irrigation depth = 3.808 inches
Since there are no losses or runoff, the amount of water stored for ET would be the effective irrigation depth minus the amount of ET that occurs during the irrigation delay period.
Amount of water stored for ET = Effective irrigation depth - (ET × Delay period)
Amount of water stored for ET = 3.808 inches - (0.19 in/day × 4 days)
Amount of water stored for ET = 3.808 inches - 0.76 inches
Amount of water stored for ET = 3.048 inches
However, it is mentioned that only 25% of the area is under irrigation. Therefore, we need to consider the irrigated area fraction as well.
Amount of water stored for ET (in the irrigated area) = Amount of water stored for ET × Irrigated area fraction
Amount of water stored for ET (in the irrigated area) = 3.048 inches × 0.25
Amount of water stored for ET (in the irrigated area) = 0.762 inches
Therefore, the amount of water stored for ET in this border strip irrigation system is approximately 0.762 inches. Among the given options, the closest answer is d) 3.815 inches.

A rock contains amphibole crystals that contain 31 atoms of 40K and 66 atoms of 40 Ar. Calculate the age of this rock. The age of this rock is ______ yrs. old
A rock contains amphibole crystals that contain 31 atoms of 40K and 66 atoms of 40 Ar. The age of this rock is 1.43 billion years old.
To calculate the age of the rock, we can use the decay of potassium-40 (40K) into argon-40 (40Ar) through radioactive decay. The ratio of 40K to 40Ar in the rock can be used to determine its age. In this case, with 31 atoms of 40K and 66 atoms of 40Ar, we can calculate the number of half-lives that have occurred. By taking the logarithm base 2 of the ratio of 40Ar to 40K, we find approximately 1.108 half-lives. Multiplying this by the half-life of 40K (1.3 billion years), we can estimate the age of the rock to be around 1.43 billion years old.
