Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

What types of technology are now available that would help reduce the negative impacts of sandstorms
Answer: Sandstorm is a storm which occurs when the wind currents are fast and they take away the sand from desert and other arid areas which impact the neighboring residential area.
Explanation:
The following are the technological measures that can be taken to reduce the effects of sandstorms:
1. Meteorological department must take initiative to aware people before sandstorm.
2. All buildings must have sandstorm alert alarms which are sensitive to sand so that people get aware about sandstorms.
3. Window pane must be regulated automatically to detect high speed wind currents to protect the lives inside the house.

Why does the grass look green under sunlight and black under the moonlight?
Answer: The original colour of grass is green because of photosynthesis. But in terms of reflection, it looks green because the sunlight reflects the green colour off the grass, so we see it as green.
Explanation: Sun appears white, but it is made up of the colors: red, orange, yellow, green, blue, indigo, and violet. When white light hits an object, it absorbs some colors and reflect the others. Grass appears green because it absorbs all the wavelengths except green. Green is reflected off the grass, so we see grass as green. The moon doesn’t have light of its own, the moon lights up because of the sun. So at night, as the light of the sun doesn't reach the grass directly because of the moon, it doesnt reflect any color off the grass, and so our eyes detect grass as black.

Which of the following is correct about mutations and genetic variation?
It must be present in a population before natural selection can act upon the population.
It arises in response to changes in the environment.
It tends to be reduced when diploid organisms produce gametes and reproduce.
It is created by the direct action of natural selection.
Answer:
a. It must be present in a population before natural selection can act upon the population.
Explanation:
Genetic variation is the difference in the DNA sequences in individuals, which makes a member of a species different from another member of the same species. It can also be said to be the differences in the genetic make up of individuals of a species population.
Genetic variation must be present in a species population before evolutionary mechanisms, such as evolution, can occur. Genetic variation must be present in a population of a species before natural selection can act upon the population, as natural selection can only increase or reduce the frequency of alleles present in the species population already.
Genetic variation in a population of species is important for natural selection to occur.
The true statement is that; "genetic mutation must exist before natural selection can act on it."
What is natural selection?The term natural selection refers to the fact that traits that are more favorable to enable an organism to survive and reproduce tend to persist in the population.
These traits usually occur due to genetic mutations. In a population, genetic mutation must exist before natural selection can act on it.

When it is summer in the U.S, why is it winter in South America?
Answer:
the suns on the other side of the earth at the time
Explanation:
hope it helps :)
Answer:
The Earth is tilted at an angle of about 23 degrees, which means that depending on where Earth is on its orbit, one pole will be getting more hours of light (summer) and one will be dark (winter).
Explanation:
Also, the earth is tilted on it's axis so more direct rays of sunlight hit the southern hemisphere making it summer in that hemisphere while it is winter in the northern hemisphere. Six months later, this reverses, and more direct rays hit the northern hemisphere. That's why it's summer here while it's winter there.
The earth's distance from the sun has nothing to do with it. It's all about the axial tilt.

Your hand touches something super gooey and icky. In the space below, describe the steps in the neural pathway that leads to pulling your hand out of the goo. Start with the stimulus
Solution :
A neural pathway may be defined as the connection that is formed by the axons which is projected from the neurons to make a synapses onto the neurons in some another location. It also enables a signal to be sent from one of the region of the nervous system to the another.
In the context, the steps in the neural pathways of our brain which leads us to pull our hand out of a icky and sticky goo is :
ICKY STIMULUS --- TOUCH / MECHANORECEPTORS ---- SENSORY NEURONS --- SPINAL CORD ---- PROCESSES IN BRAIN ---- SPINAL CORD ---- MOTOR NEURONS ---- MUSCLE MOVEMENT.

how does the thyroid gland help maintain and regulate calcium?
Answer:
When the calcium level is high in the bloodstream, the thyroid gland releases calcitonin. Calcitonin slows down the activity of the osteoclasts found in bone. This decreases blood calcium levels. When calcium levels decrease, this stimulates the parathyroid gland to release parathyroid hormone.
