It is flu season! The flu is caused by a virus. Scientists continue to debate whether or not viruses are alive. If we consider the image of the flu virus seen here, we could say that a virus is NOT alive because https://www.usatestprep.com/modules/gallery/file.php?id=1531 for the picture
Answer: the answer is D
Explanation:
Answer: There is no cellular structure
Explanation: If we use the image to support our argument, we could say a virus s not living because there is no cellular structure. All prokaryotic cells lack a nucleus. We cannot tell, from the image, anything about its way of life.

How has genetics changed overtime
Answer:
Mutations involve changes in the arrangement of the bases that make up a gene. Even a change in just one base among the thousands of bases that make up a gene can have a major effect. A gene mutation can affect the cell in many ways. Some mutations stop a protein from being made at all.

Studies have shown that children are especially vulnerable to the effects of ultraviolet (UV) radiation. Tanning beds expose the skin to nearly ten times as much UV radiation as natural sunlight. With that knowledge, a law was passed in some states to prevent individuals under the age of 18 from using tanning beds. Which statement best explains why UV radiation is so harmful?
a) It can increase harmful DNA mutations in cells.
b) Diseases are all caused by exposure to environmental factors.
c) Homeostasis in an organism is increased by the presence of UV radiation.
d)UV Radiation decreases the likelihood that mutations will occur.
Hello there!!
The answer, I think, would be A.
UV radiation can create problems in the correctness of cell replication, which can result in mutated cells.
I hope this answers your question!
Tanning beds can increase harmful DNA mutations in cells. So, the correct option is A.
What are Tanning beds?In order to tan individuals, a tanning bed emits UV radiation (make their skin darker). If someone spends too much time in the tanning bed, it can also burn their skin, much like the sun. Many types of tanning beds exist. Using tanning beds can lead to more damaging DNA alterations in cells.
Special fluorescent lights (16–32 per tanning bed) that produce both visible and UV light are used in tanning beds. They employ a ballast system, like all fluorescent lights, to keep the amount of electricity going to each lamp to a maximum of 100 watts per lamp. A specific acrylic, or clear shield, is used over the bulbs in tanning beds.
Therefore, the correct option is A.

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
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.

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.
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 adaptation to a dry climate most helps the elephant tree continue to grow by reducing the loss of moisture?
A
a deep root system
B
loss of leaves during a drought
C
photosynthesis in the bark
D
closing of stomata in daylight
a - a deep root system
The closing of stomata in daylight is an adaptation to a dry climate most helps the elephant tree continue to grow by reducing the loss of moisture (Option D).
What is an adaptation?An adaptation is a phenotypic feature that allows an organism to survive in particular environmental conditions.
Stomata are structures in plants that allow the interchange of gases required during photosynthesis.The closing of stomata represents an adaptation to arid conditions because it avoids water loss.In conclusion, the closing of stomata in daylight is an adaptation to a dry climate most helps the elephant tree continue to grow by reducing the loss of moisture (Option D).

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.
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.
