Answers
Answer: A or D
Explanation:
For many years, scientists thought that the universe was static—that it had always existed and been the same, and it was neither expanding nor contracting. Then, in the late 1920s, Edwin Hubble recognized that the shift in light from distant objects toward the red end of the spectrum meant that those objects were moving away from Earth. The best explanation for these observations was that the universe was not static but was expanding. More recent observations, such as cosmic background radiation, are also better explained by an expanding universe rather than a static universe. What aspect of scientific methodology best explains the replacement of the static universe theory with the expanding universe theory?
A Science and its methods are always improving. Scientists needed newer, more sensitive instruments to detect the slow expansion of the universe.
B Hubble’s observations were extremely popular with the public, leading to overwhelming support for the new theory.
C The new theory explained Hubble’s observations, and it was tested and supported by additional observations. The theory was accepted because it was the most powerful explanation available for many observations.
D The natural progression of science is that all theories are eventually replaced by new theories until one is established as law
Answers
Answer:
C
Explanation:
B has nothing to do with the scientific method. The public does not determine a scientific law. Facts do.
D may be sort of true, but it does not explain Hubble's process. Nor does it explain what Hubble actually did and how he reported it. D is incorrect.
A was never implied (although it is likely true. On the other hand, many great scientific principles are uncovered with very simple apparatus.) A might be 1/2 true.
I think the best answer is C. It is general enough to be accepted. There are two theories mentioned. So C is the best answer.

When soil first forms over bare rock, what is it made of?
Answers
Answer:
Explanation:
Weathering and erosion produce ever smaller rock particles which,
when mixed with dust and decayed organic matter over time ,
result in different types of soil .
Soil is formed by the process of weathering. The soil is the uppermost layer of the surface of Earth. The first formed soil contains pieces of rocks and other particles.
What is Soil?Soil is the uppermost thin layer of material covering the earth's surface. It is formed from the weathering of large rocks. It is made up of mineral particles, organic materials, air, water and living organisms like bacteria.
The lichens are the pioneer species which invade the bare rocks and convert them into soil. They secrete acids which dissolve the rocks. This helps in their weathering and formation of soil. Mosses grow on the rocks along with the lichens to form a mat over the substratum.
Under the action of factors like heat, cold, rain, wind, and other atmospheric factors, the rock breaks down physically into the parent material of the soil.

Your lungs take in air through the mouth and nose. Explain how the lungs function in the human body.
A) They coordinate the movement of the heart.
B) They pass oxygen from the air into the blood.
C) They pump the blood throughout the body.
D) They remove carbon dioxide from the air.
Answers
Answer:
Your answer would be "B) They pass oxygen from the air into the blood."
Explanation:
They certainly don't coordinate the movement of the heart, so A isn't an option.
The lungs also don't pump blood through the body, that's the hearts job.
And the lungs do not filter carbon out of the air, which eliminates D.
Therefore your answer is B.
The lungs function in the human body by passing oxygen from the air into the blood.
Gaseous exchange in the lungGaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.
A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.
In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.

Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?
Answers
Hi, rachellelunaa!!
I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.
I really hope this answers your question!!
The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.
What are the cranial bones?Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).
The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.
Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.
Therefore, preventing damage to skull and brain, we are born with separate cranial bones.

Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answers
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?
Answers
Answer:
XX
Explanation:
ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.
ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.
What is ACTN3 genotype and XX?ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.
The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.
Therefore, XX of the ACTN3 genotype is advantageous for athletes.
