read the story below about Chloe and Khalil, two students from another school who are also learning about the Earth, Moon, and sun. Then, answer the question below.
Chloe is a photographer for the school paper. After learning about Eric Wu’s assignment for About Space magazine, she decided to try to take her own picture of a lunar eclipse for the school paper. However, on the night of the lunar eclipse, Chloe wasn’t feeling well, so her parents wouldn’t let her go outside with her camera.
The next day at school, Chloe was feeling disappointed, so her friend Khalil tried to cheer her up. “Don’t worry,” he said. “Remember, we learned that the Moon moves in the same circle around Earth each month. That means you can photograph a lunar eclipse when Earth is in between the sun and the Moon again next month.”
“Maybe, but maybe not,” Chloe said. “A lunar eclipse happens sometimes when Earth is in between the sun and the Moon, but not always. It could be a long time before I have another opportunity to take a picture of a lunar eclipse.”
When can a lunar eclipse be photographed?
Claim 1: A lunar eclipse can be photographed any time Earth is in between the sun and the Moon.
Claim 2: A lunar eclipse can be photographed sometimes when Earth is in between the sun and the Moon.
Answer: Claim 2
Explanation: Since the moon is in earth's orbit and the earth is tilted on an axis sometimes there won't be a lunar eclipse.
Answer: Claim 2
Explanation: Since the moon is in earth's orbit and the earth is tilted on an axis sometimes there won't be a lunar eclipse.

Hormones control some actions in the body. The nervous system controls some actions as well. Reflex actions are part of the nervous system.
Give TWO ways in which a hormone-controlled action is different from a reflex action.
Answer:
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurones, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. This means that communication is faster when using the nervous system.

What are Sedimentary rocks?Sedimentary rocks are defined as the type of rocks that are formed by the accumulation or deposition of mineral or organic particles on the surface of the earth, followed by cementation. Sedimentation is describe as the collective name for the processes that cause these particles to settle in place.
Sedimentary rocks are formed on or near the Earth's surface when compare to metamorphic and igneous rocks, which are formed deep within the Earth. Sedimentary rocks are composed of particles of existing rock that have been weathered off by physical processes such as wind and water movement.
Therefore, the correct option is C.

Answer:
answer below
Explanation:
TRUE
1)Evidence:All living organisms are divided into three domains: Bacteria, Archaeaand Eukarya. All the organisms that possess a eukaryotic cell, plants, animals,protists, fungi are in the Eukarya domain. Therefore, mammals and plantsbelong to the same domain, the Eukarya domain.
2)FALSE
FACT: plants and animals belong to the same domain called the Eukarya.
Evidence: the domain Eukarya is divided into four kingdoms namely; Protista, Fungi, Plantae and Animalia
Explanation
According to the last universal common ancestor (LUCA) there are three cell types that each represents a domain namely; Bacteria, Archaea, Eukaryota. Living organisms are placed in to different kingdoms which are; Animals, Plants, Fungi, Bacteria and Protists. So The statement above is a myth.

What is the difference between the muscle in your heart and the muscles in your hand?
Answer:
The muscle that makes up the heart is called the cardiac muscle. It is also known as the myocardium. The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body. The interossei muscles begin between the bones of the hand. There are four dorsal and three palmar interossei muscles. While all interossei bend the MCP joints, the dorsal interossei allow us to spread our fingers away from each other. The palmar interossei pull our fingers together.

When writing a research paper, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your research paper is credible.
Use sources that end in .gov. These government sites are reliable sources. You can also use sites ending in .edu. They’re generally trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the source’s author before proceeding. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions:
Who authored the document?
Is the author a genetics expert?
What is the document’s purpose?
Does the document state facts that scientists can prove with evidence?
Does the document include opinions?
How old is the document?
Do other credible sources support the document’s statements?
Search for credible websites and note the information they contain. Write down two sources that you’ll use for your research paper, and cite them using Modern Language Association (MLA) citation methods.
A sample citation of sources using the MLA citation methods is Author(s). "Title of Article." Title of Periodical, Day Month Year, pages.
What is a Research Paper?This refers to the expanded essay that is written in order to find answers to research questions in an academic writing format.
Hence, we can already see that a list of reliable sources has been mentioned already and the important questions to ask when using sources for a research paper.
Therefore, we can see that when using Modern Language Association (MLA) citation methods, one should place the name of the author(s) in alphabetical order, then the title of the article, day, month, and year, then the pagination.

Answer:
In bioethics, the ethics of cloning refers to a variety of ethical positions regarding the practice and possibilities of cloning, especially human cloning. While many of these views are religious in origin, some of the questions raised by cloning are faced by secular perspectives as well. Perspectives on human cloning are theoretical, as human therapeutic and reproductive cloning are not commercially used; animals are currently cloned in laboratories and in livestock production.
Advocates support the development of therapeutic cloning in order to generate tissues and whole organs to treat patients who otherwise cannot obtain transplants, to avoid the need for immunosuppressive drugs, and to stave off the effects of aging. Advocates for reproductive cloning believe that parents who cannot otherwise procreate should have access to technology.
Opponents of cloning have concerns that technology is not yet developed enough to be safe, and that it could be prone to abuse, either in the form of clones raised as slaves, or leading to the generation of humans from whom organs and tissues would be harvested. Opponents have also raised concerns about how cloned individuals could integrate with families and with society at large.
Religious groups are divided, with some opposing the technology as usurping God's place and, to the extent embryos are used, destroying a human life; others support therapeutic cloning's potential life-saving benefits.
Cloning of animals is opposed by animal-groups due to the number of cloned animals that suffer from malformations before they die, and while meat of cloned animals has been approved by the US FDA, its use is opposed by some other groups concerned about food safety.

The images below show two types of finches that live on different Galapagos Islands. Scientists have found that these two finches are genetically related, but they eat different kinds of seeds. One species eats larger and harder seeds than the other species.
What process caused these birds to have beaks with different shapes?
Answer:
The correct answer is - natural selection or more precisely adaptive radiation.
Explanation:
Adaptive radiation is the process in the evolution of an animal or organism into different types of species or types specialized to fit different environmental conditions. These are depend on the various condition like food availablity or weather or any environemnt condition. It is the part of the natural selection that involves adapting the beneficial traits into genome of an organism over time period.
In galpago finches they are adapted different morphological condtions, based in food availblity in the particular environments even they had same ancestor is the best example of the adaptive radiation.

"The koalas are one of nature’s most fussy eaters. It will only eat the leaves and young shoots of the eucalyptus tree. It also eats the tree’s stems, flowers, and bark, but it likes the leaves best. And not just the leaves of any eucalyptus tree. Of the more than seven hundred varieties of eucalyptus, the koala will only eat from about three dozen of them. The koala must eat between 1 and 1.5 pound (454 and 680 grams) of eucalyptus leaves a day to provide it with enough nutrition to survive."
"When Europeans first arrived in Australia in the 1700s there were possibly 10 million or more koalas. In the following two centuries, the population has fallen dramatically. Scientists do not always agree on the current size of the koala population, although some believe the total number is somewhere between 100,000 and 200,000"
