Potassium-40 has a half-life of 1.3 billion years. If a rock was
determined to be around 3.9 billion years old what percentage
of the original potassium-40 would be left in that rock sample?
Answer: The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.
Matt use a camera to take a picture of a rose on a piece of paper in the picture the rose appear to be bright red and the background appear to be white then Matt place a blue glass filter over the camera lens and took another picture in this picture of the Rose appear to be black in the background appear to be blue explain what happens to light waves to make the appearance of the rules in the appearance of the background different in the two pictures.
The blue glass filter absorbed most of the red light waves and allowed only the blue light waves to pass through, resulting in the appearance of the rose and the background being different in the two pictures.
What is Light?
Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in straight lines and has both wave-like and particle-like properties. Light is a fundamental part of our world and plays a crucial role in our lives.
Light is produced by the motion of charged particles, such as electrons, and can be emitted by sources such as the sun, light bulbs, and fires. Light travels at a constant speed of approximately 299,792,458 meters per second in a vacuum, which is known as the speed of light.
When Matt took the first picture of the rose on a piece of paper without any filter, the camera captured the visible light waves that were reflected by the rose and the background. The rose appeared bright red because it reflects mostly red light waves and absorbs other colors, and the background appeared white because it reflects all the visible light waves equally.

Answer: From carbon dioxide and water
Explanation:
Glucose is a type of carbohydrate which is produced as a product of the biochemical reaction that is photosynthesis. Carbon dioxide and water are the reactants used for the synthesis of glucose. The carbon dioxide is obtained from the atmosphere and water from the roots. Carbon, hydrogen, and oxygen are the elements that are present in the carbohydrate through reactants named carbon dioxide and water.

Which best describes tA male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? he fossil record?
Question:
A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
Answer:
Feather color loses importance in sexual selection and becomes disadvantageous for males. There is a decrease in red color variation among males.
Explanation:
In cardinal species, females choose males to mate according to their vibrant red color. The redder the male is, the better genetic charge it has, and the better choice for mating it becomes.
Red feather color is a trait that reflects the genetic quality of males. So individuals with the most vibrant red color express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.
The brightest or most vibrant males are in red, the better chances they have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors to enhance mating chances.
However, if females begin using different criteria than feather color when they choose mates, color production stops making sense. What is even more, it becomes more disadvantageous for males because females do not use color for their choices, males spend energy when producing it, and the redder the males are, the more chances to be predated they have. So basically, males´ feather color loses importance. The selection pressure in males turns to the evolution of another trait. The shade variation of red feathers will decrease over time.

Which of the following energy producing technologies can be beneficial to soil quality
A. Biomass
B. Solar
C. Wind
D. Oil
Answer:
Both solar energy and wind energy are beneficial to soil quality. They are not using fossil fuels that both harm the soil with digging and fracking, but also are not being burnt which harms the air and can create acid rain. Both solar and wind are using nature to benefit the world. As long as the sun keeps burning and the world turning, we will continue to be able to use them.

Why are there many, many more craters on the "outer back" side of the moon than there are on the "inner facing" side of the moon?
Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.
Explanation:
The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.
