What is the function of the contractile vacuole? What would happen if the cell did not have this organelle?

Answers

Answer 1
Toward the posterior of the cell is a star-like structure, the contractile vacuole. This organelle helps the cell remove excess water, and without it, the euglena could take in some much water due to osmosis that the cell would explode.

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.

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.

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.”

Answers

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.

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.

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.

Answers

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?

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.

Premed students are often traumatized by studying for their MCAT exam, which historically was always taken at the end of their Junior year in college. Now, many medical schools desire a meaningful gap year between completion of an undergrad degree and entrance to medical school so that incoming students have some sort of life-time experience either working, doing research, charity outreach, or traveling during that time. As a result, modern pre-med students often wait to study for their MCAT until after they graduate without realizing that it means they will end up taking two gap years, not one.
