What are the layers of the earth?Earth has many different layers based on their arrangements and occurrences. The crust is the first layer of the earth where humans and other organisms live and ranges from 6 -70 km thick. It is followed by the Moho barrier.
The Moho barrier is the layer that separates the crust from the mantle and is followed by the mantle layer where the convection in the tectonic plates leads to earthquakes.
The deepest and the innermost layer is the core where the solid and liquid hot gases are found at very high temperatures. It is very hot and composed of iron and nickel.
Therefore, the matches are 1. c, 2. d, 3. b, and 4. a.

PLEASE SOMEONE HELP ME I’M REALLY STRUGGLING
Answer:seventy-seven thousand years ago, a craftsman sat in a cave in a limestone cliff overlooking the rocky coast of what is now the Indian Ocean. It was a beautiful spot, a workshop with a glorious natural picture window, cooled by a sea breeze in summer, warmed by a small fire in winter. The sandy cliff top above was covered with a white-flowering shrub that one distant day would be known as blombos and give this place the name Blombos Cave.

How does uplift change the surface of Earth?
O A. Snow melts on the surface of Earth, causing rivers to form.
B. Magma rises from the surface of Earth, causing lava beds to form.
O C. Wind blows across the surface of Earth, causing sand dunes to form.
O D. Pressure builds under the surface of Earth, causing mountains to form.
Answer/ Explanation:
B. Magma rises from the surface of Earth, causing lava beds to form.
From below or decreasing downward force weigh from above. During uplift, land, as well as the sea floor, rises. All this movement can cause rocks that were once underground to be brought up to the Earth's surface. This process is called uplift.

5. A student is studying how sound travels
through a solid medium by timing
the movement of sound through a
boulder when the boulder is at different
temperatures. Using the information above,
how fast will sound move through the
boulder when it reaches 20°C?
Answer:
570 m/s
Explanation:
The speed of sound is a measure of how fast sound travels through a medium. The speed of sound through various media varies. Sound travels fastest through solids and slowest through gases for example air.
The temperature of a medium affects the speed of sound through that medium. The higher the temperature, the faster sound travels through the medium. This is because, as the temperature of the medium increases, the particles of the medium vibrates faster and faster, thus sound waves are able to be propagated faster through that medium.
From the information provided in the attachment, the speed of sound through the boulder increase by 2 m/s for every 5°C rise in temperature. Therefore, the speed of sound through the boulder when it reaches 20°C will be 570 m/s

A Class-A 10 mL pipette is supposed to dispense 10.00 mL of water. A lab technician makes three measurements of the volume that the pipette actually dispenses, and obtains volumes of 9.70 mL, 9.69 mL, and 9.71 mL. The pipette is:__________
a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise
Answer:
d) Neither accurate or precise
Explanation:
Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

John Terborgh, tropical ecologist at Duke University, asserts that in order to save tropical forests, citizens of industrial nations are going to have to pay developing countries. Do you agree
Answer:
I do agree
Explanation:
As a personal opinion, I do agree with this statement. Citizens of developing countries use these rain forests for many reasons. One of which is for survival they cut down and use what they need in order to gather the resources that they need and build their habitats. This goes slowly destroying the rainforests. The other reason is that these citizens many times sell the rights to the rainforest land to mining companies that ultimately destroy the rainforest for its resources. The only way to prevent both of these from happening is by paying these developing countries to protect the rainforest instead of profiting from it.
Wolves that live in snowy climates often prey on rabbits. Some rabbits can move quickly across deep snow because they have large feet that don’t sink into the snow. Rabbits without this adaptation move more slowly across the snow. Which statement best justifies how the rabbit population changes over time?
A. Sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.
B. The ocean water would change its current so that the acidic water is relocated to another area and allow sea coral to survive.
C. The ocean water would change its composition to reduce the amount of carbon dioxide contained and allow sea coral to survive.
D. Sea coral would become extinct because of its inability to make adaptations fast enough to adjust to the changes in the environment
Answer:
It's A
Explanation:
Just like the corals have genetic mutations to adapt to their environment so do the rabbits change their genetic characteristics to make sure the species continue it's lineage by evolving and growing their feet so they can be faster and not sink in the snow, becoming harder preys to catch, otherwise, if their paws were smaller, they would be slower and, therefor, an easy catch for the wolves, probably becoming extinct after awhile.
The statement that justifies how the rabbit population changes over time is sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment. So, the correct option is A.
What is Adaptation?Adaptation is the process by which a species becomes fitted to its environment; it is the result of natural selection's acting upon heritable changes.
Rabbits have to change their genetic characteristics same as the coral have genetic mutations to adapt to their environment and to make sure the species continue its downstream by evolving and growing their feet, so they can run faster in the snow and successfully escape from predators. If rabbits are not evolved with an environment that does not favor them, they are surely eliminated from nature.
Therefore, the statement that justifies how the rabbit population changes over time are sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I
Answer:
This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.
Explanation:
During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

Propose an explanation for why humans have experienced exponential growth since the Industrial Revolution? (why was our population able to live longer and reproduce more successfully). What do we have access to now that was nonexistent or difficult to access in the past?
Answer:
The Industrial revolution increased chances of survival for human due to technology and increased ways to get food
Explanation:
The human population of the planet increased gradually for more than 10,000 years after the Agricultural Revolution. As the population continues to grow, competition for resources will increase. Natural disasters and political conflicts will exacerbate the problems, especially in the more stressed regions of developing nations. The survivors of this competition will likely be determined by factors such as place of birth and educational opportunities.
