what produces the cell cycle?
Answer:
The cell cycle can be thought of as the life cycle of a cell. In other words, it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a mother cell—and reproduction—division to make two new daughter cells.
Which of the following environmental factors would positively influence the survival and reproduction of only light peppered moths?
A.
A forest fire that burns down the trees.
B.
Laws that improve air quality and restrict pollution.
C.
Increasing the number of factories that burn coal into the air.
D.
A disease that infects the light peppered moths and not the dark.
Answer:
The correct answer is - option B. laws that improve air quality and restrict pollution.
Explanation:
The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.
This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.

During science class, Mauricio made sketches of the major organelles of the cell. Which of the following is his sketch of a mitochondrion?
Answer: B
Explanation: I did The test
During science class, Mauricio made sketches of the major organelles of the cell. The second sketch describes a mitochondrion. The correct option is B.
What are mitochondria?The “powerhouses” of the cell, mitochondria, break down fuel molecules and harvest energy during cellular respiration. Chloroplasts and mitochondria probably started as microorganisms that were swallowed by larger cells (the endosymbiont theory).
A mitochondrion is a membrane-containing cell organelle. It is the site of energy-producing metabolic processes and cellular respiration. The process happens inside mitochondria.
Thus, the link between cellular respiration and photosynthesis is that the reactant in photosynthesis is a byproduct of cellular respiration.
Therefore, the correct option is diagram B.

Stanimar is staying in the hospital after surgery. He starts to suffer from a fever, diarrhea, and abdominal pain. How did Stanimar most likely contract his nosocomial infection?
A urinary catheter was not properly sterilized before it was used.
O A nurse did not properly disinfect her hands before she inserted the ventilator during surgery.
O A health-care worker did not disinfect her hands after she helped another patient to the bathroom.
O The surgical instruments that were used during his surgery were not properly cleaned before his procedure.
Answer: I believe the answer to be a.
Explanation: The symptoms listed are cause of a urinary tract infection, so the most likely answer would have to do with the one having to do with the urinary tract and can often cause a very hideous infection.
Stanimar most likely contract his nosocomial infection through the fact that involves the mechanism of a urinary catheter was not properly sterilized before it was used. Thus, the correct option is A.
What is Nosocomial infection?Nosocomial infection may be defined as a form of healthcare-associated infection that is acquired during the process of receiving health care that was not present during the time of admission.
Some common types of Nosocomial infection include urinary tract infections, respiratory pneumonia, surgical site wound infections, bacteremia, and gastrointestinal and skin infections.
The nosocomial infection generally spread through the pathogens like Staphylococcus aureus, Pseudomonas aeruginosa, and E. coli.
As Stnimar is suffering from a fever, diarrhea, and abdominal pain, he definitely has a urinary tract infection. It may arise due to the contamination of a urinary catheter that was not properly sterilized before it was used.

Explain how photosynthesis provides energy for consumers.
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

The New Orleans Musicians' Clinic did not make any recommendations about low or high pitch sounds. Why are high pitch sounds less damaging to ears than louder sounds? Use your model and what you have learned about sound waves and energy to write an explanation. Some helpful words to include in your response are: transfer, energy, eardrum, and air particles.
Answer:
Due to high energy.
Explanation:
High pitch sounds less damaging to ears than louder sounds because louder sounds contains more energy than high pitch sound. When this high energy of loud sound transfer from air particles towards our eardrum, it can greatly damaged the ear while on the other hand, high pitch sound has low energy so it causes less damaged to the eardrum.

Answer: You picked the correct answer, "They all inherited their traits from a common ancestor."
Explanation: Well, one I had a test on this question too and I got it right. Second, if all species shown have something in common (structures) than they most likely got it from a common ancestor.
They all inherit their traits from a common ancestor. So, the correct option is C.
What is an Ancestor?An ancestor is a parent or the parent of an antecedent, commonly referred to as a forefather, fore-elder, or forebear. Each individual from whom one is born is an ancestor. The individual who has received an estate, according to law.
Anybody we are descended from is an ancestor. To descend in a family implies to "come from." The parents, who in turn descended through their parents, who in turn descended from the parents, and so forth. The ancestors are the line of parents and kids.
Your ancestors are your mother, father, and grandparents. If matrilineal descent is practiced in the culture or civilization, your mother and grandmother are the ancestors but not your dad or grandfather. They all derive their characteristics from an in this instance.

Which of the following is typical of aerobic respiration?
decreases a plant’s weight
contains two stages, glycolysis and fermentation
produces methane as a byproduct
produces little energy
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".

Competition is a driving force behind natural selection. Which of these statements best
describes why competition is a constant pressure?
Answer:
The options are not given, here are the options gotten from another website.
A. Organisms produce more offspring than can survive
B. Organisms are taught to fight others of the same species
C. Organisms are taught to fight others of the same species
D. Multiple species fill the same niche and competition will always arise against other species
The correct option is D.
Multiple species fill the same niche and competition will always arise against other species.
Explanation:
This is because competition arises when different organisms living a niche compete for space or resources and this can be as a result of too much population in a niche and limited resources and space. Organisms tend to compete for survival which is the driving force of natural selection.
These u because as competition rises, species tend to develop traits which will help them to survive, adapt , reproduce and compete well in their environment an this result in survival of the fittest....that is those that can adapt well.
