Following fertilization and two rounds of cell cleavage, each of the four cells of a frog embryo has a centriole that is preparing for the next cleavage. The centriole in each of these cells can trace its origins back to the original centriole provided by the _______ prior to the first cleavage. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices secondary oocyte sperm ootid oogonium primary oocyte
Answers
Answer:
sperm
Explanation:
Centrioles are cylindrical organelles that play a major role during cell division, where they work to form the centrosome which duplicates and moves to opposite ends of the cell. The proximal centriole provided by the sperm cell mediates the separation of chromatids during the first cleavage of the fertilized egg. Upon fertilization, the proximal centriole forms the aster rays where microtubules act as a guide for the migration of the female pronucleus.

Is DNA replication always a foolproof process? Explain your answer.
Answers
Answer: No. Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism.
Explanation:
No, replication is not always a foolproof process although many proteins look for DNA damage or mistakes, damaged areas can still replicate. This can lead to gene rearrangements and serious problems in the body.
Some mutations are caused by mistakes in DNA replication. DNA replication isn’t always 100% complete. Sometimes, an incorrect base is inserted into the new DNA strand. This incorrect base can become permanent.
Breaks in DNA are caused by DNA replication errors, particularly those in regions that are difficult to replicate, known as fragile sites.
Breaks in DNA can cause cancer, mainly because they increase the risk of chromosome fragments rearranging themselves and activating genes that cause uncontrolled cell division.

See Concept 43.1 (Page 953) dependent on surface secretions from sebaceous and sweat glands, which give the skin an acidic pH that is unfavorable for bacterial colonization based on the trapping of microbes by mucus dependent exclusively on cell-mediated responses characteristics of all vertebrate animals dependent on tears, saliva, and mucous secretions that contain lysozyme, an enzyme that digests bacterial cell walls
Answers
Answer:
The correct answer is - characteristics of all vertebrate animals.
Explanation:
Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.
The only characteristic among these that present in both is that they both immune systems found in all vertebrates.

True or false
Answers
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.

What is one disadvantage of desalination?
The process can ultilize solar energy to lower its cost.
The process uses fuel that is expensive.
The process makes water that is unsafe to drink.
The process is too difficult to carry out in big cities.
Answers
Answer:
B
Explanation:
Desalination remains expensive, as it requires enormous amounts of energy. The correct answer is b) The process uses fuel that is expensive.
What is desalination?Saline water which is typically sea water, is artificially transformed into fresh water through a process called desalination. Reverse osmosis and distillation are the two most used desalination techniques. There are several approaches. Although each has benefits and drawbacks, they are all useful.
The issue is that it takes a lot of energy to desalinate water. When salt is dissolved in water, it forms strong chemical bonds that are challenging to break. Desalinating water may be rather expensive since both the energy and the technology required are costly.
Desalination turns seawater into freshwater by removing the salt, however, it also has certain unfavorable effects on the ecosystem. Desalination facilities release trash and poisonous chemicals that are bad for the environment and animals. The procedure can also increase the salinity of saltwater, which has an impact on fish.
Therefore, the correct answer is b).
