Which of these is a distinguishing abiotic feature of the Great Barrier Reef
Final answer:
The Great Barrier Reef's warm shallow waters and calcium carbonate skeletons secreted by coral organisms are key abiotic features of the ecosystem.
Explanation:
The Great Barrier Reef is the largest barrier reef in the world and a quintessential example of a marine ecosystem. One distinguishing abiotic feature of the Great Barrier Reef is its water temperature. The Great Barrier Reef exists in warm, shallow waters within the photic zone of the ocean, which is crucial for the coral organisms that form the reef. These organisms, colonies of saltwater polyps, secrete calcium carbonate skeletons which accumulate over time to form the structure of the reef. Therefore, the warm waters and the structure of the calcium-rich skeletons are significant abiotic features that contribute to the formation and maintenance of this underwater wonder.

Which condition feeds a tropical storm as it develops into a hurricane? A. heat and moisture B. cool temperatures and rain C. high temperatures and freshwater D. wind and dry air
Hurricanes form over tropical waters (between 8 and 20 degrees latitude) in areas of high humidity, light winds, and warm sea surface temperatures [typically 26.5 degrees Celsius (80 Fahrenheit) or greater]. These conditions usually prevail in the summer and early fall months of the tropical North Atlantic and North Pacific Oceans, and for this reason, hurricane “season” in the northern hemisphere runs from June through November.
The first sign of hurricane genesis (development) is the appearance of a cluster of thunderstorms over the tropical oceans, called a tropical disturbance. Tropical disturbances generally form in one of three ways, all of which involve the convergence of surface winds. When winds come together (converge), the force of the collision forces air to rise, initiating thunderstorms.

Which process occurs during asexual reproduction? A. Crossing-over between homologues B. Mutation C. Separation of homologous pairs of chromosomes D. Separation of sister chromatid
A. Crossing-over between homologues.
Explanation:In meiosis and mitosis, recombination happens between comparable particles of DNA (homologous groupings). In meiosis, non-sister homologous chromosomes pair with each other so recombination ordinarily occurs between non-sister homologs.
All living organism reproduces either through asexual reproduction or sexual reproduction or sometimes through both mode of reproduction. In both cases let it be sexual or asexual, the mode of cell division namely meiotic and mitotic cell division, the recombination between homologous chromosomes is a typical system utilized in reproduction.

which part of photosynthesis requires ATP, NADPH, and carbon dioxide to produce glucose
Final answer:
The Calvin Cycle or light-independent reactions of photosynthesis use ATP, NADPH, and carbon dioxide to produce glucose.
Explanation:
The part of photosynthesis that requires ATP, NADPH, and carbon dioxide to produce glucose is known as the Calvin Cycle, or the light-independent reactions. These reactions do not require light to occur and are responsible for the fixation of carbon dioxide into organic molecules. In the process of carbon fixation, CO₂ is 'fixed' from an inorganic to an organic form and then, using the ATP and NADPH generated from the light-dependent reactions, these fixed carbons are combined to form sugar molecules such as glucose.

Which abnormal skin growth results from a virus?
freckles
moles
warts
jaundice
Warts are the abnormal skin growths that result from a virus. While freckles, moles, and jaundice are also skin conditions, they are not typically caused by a virus. Instead, each has different causes such as sun exposure, genetics, and high levels of bilirubin respectively.
Explanation:The abnormal skin growth that results from a virus is a wart. Warts are rough, usually skin-colored growths that appear on the skin and mucous membranes. They are caused by the human papillomavirus (HPV). The virus infects the top layer of the skin and causes it to grow quickly, leading to a wart. While freckles, moles, and jaundice can also be familiar terms related to skin conditions, these are not typically caused by a virus.
For instance, freckles aren't caused by a virus but are small, brownish spots on the skin that can appear as a result of sun exposure and genetics. Moles, which are small skin marks caused by pigment-producing cells in the skin, are mostly harmless and aren't typically caused by a virus. Meanwhile, jaundice is a result of high levels of bilirubin in the body and causes a yellowing of the skin and eyes, but it is not related to a viral infection.

List 4 cell organelles and their function (what they do) in the eukaryotic cell.
Final answer:
Eukaryotic cells contain organelles such as the nucleus that stores DNA, mitochondria that produce energy, vesicles for transporting materials, and vacuoles for storage.
Explanation:
Four Cell Organelles and Their Functions in Eukaryotic Cells
The eukaryotic cell is highly compartmentalized, with specialized structures called organelles, akin to a factory where each 'machine' or organelle has a distinct function. Here are four key organelles and their roles:
Nucleus: Functions like a safe, housing the genetic material (DNA) necessary for building proteins and governing cellular functions.Mitochondria: Known as the powerhouses of the cell, these organelles produce cellular energy, mainly in the form of ATP (adenosine triphosphate), through the process of cellular respiration.Vesicles: Small membrane-bound sacs that are involved in the transport of materials within the cell and to the cell membrane.Vacuoles: Storage centers within the cell, with plant cells possessing larger vacuoles for storing water and nutrients than animal cells.
These organelles are vital for the cell's functionality and survival, each enabling the cell to perform complex and specialized tasks, largely unparalleled by the more basic prokaryotic cells.

The underwear in the image keeps you warm on cold nights because it A) keeps cold air out. B) is a poor insulator. C) is a good insulator. D) is a good conductor.
Prevents Conduction
Answer:
Option C, is a good insulator
Explanation:
See the attached image of the underwear
Solution
As it is clear in the image, the fabric of the underwear is poly fabric which acts as a good insulator.
Being an insulator, it can easily trap the heat of the body during winters and does not allow this heat to escape due to which it is successful in keeping a person warm during the winters.
If the material of the underwear would have been a conductor, it would have allowed heat of the body to escape.
Hence, option C is correct

If the ductus deferens tubes are cut and tied (vasectomy), the semen will not contain select one:
a. fructose.
b. buffers.
c. mucus.
d. sperm.
e. all of these.
If the ductus deferens tubes are cut and tied, the semen will not contain sperms. This is known as vasectomy. This procedure is performed in males to control population. Thus, the correct option is D.
What is Vasectomy?
Vasectomy is the permanent male sterilization procedure. It is a surgical procedure which involves the cutting or sealing of the ductus deferens tubes which carries a man's sperm to permanently prevent pregnancy. It is usually carried out by giving a local anesthetic to the client, where the man is awake but could not feel the pain, and this procedure complete in about 15 minutes.
Once the tubes are cut, sperms cannot enter into the semen of man or out of the body. However, the testes do produce sperms, but the sperms die and absorbed by the body. A man who have undergone a vasectomy still produces the semen and is also able to ejaculate it. But, the semen contains everything except sperms.
Therefore, the correct option is D.
