All the modern species of bison have evolved overtime just as all living organisms evolve over time.
Answers
Answer:
The working assumption for many years was that, like North American bison, European bison evolved from steppe bison. ... Their results suggest that the European bison is the result of inter-breeding, over 120,000 years ago, between steppe bison and aurochs; the wild ancestors of modern domestic cattle.
Our study suggests that the first bison arrived in North America 195 - 135 thousand years ago over a land bridge between Asia and Alaska. They quickly spread and evolved (changed) into different forms to adapt to their new environments.

Answers
Answer:
the answer is A before cell division (mitosis or meiosis)
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

E) All of the answers are correct. 107) Which of the following is NOT primarily a sexually transmitted infection (STI)
Answers
Answer:
1. A) Lactobacillus
2. A) Escherichia coli. 3.
3. You did not present the answer options, which prevent this question from being answered. However, I will try to help you with the explanation below.
Explanation:
1. An adult vagina has a microbiota, that is, a group of microorganisms. This microbiota is beneficial and exists to promote protection and vaginal balance. Among the microorganisms present in the microbiota, we can mention Lactobacillus, which are responsible for preventing infections and controlling vaginal pH.
2. Cystitis is a urinary infection caused by the bacteria Escherichia coli, which resides in the human body and is important for digestion, but can cause inflammation of the bladder, as well as other stomach bacteria. Cystitis is not a contagious disease and has symptoms such as fever and difficulty urinating.
3. Sexually transmitted diseases are contagious diseases, caused by microorganisms that are transmitted from one person to another during an unprotected sexual act. Therefore, to answer the third question you should look for the answer option that presents a disease that is not transmitted by unprotected sexual contact.
104. Lactobacillus, 105. Escherichia coli, 106. Pyelonephritis, 107. Neisseria gonorrhoeae.
26. The normal microbiota of the adult vagina primarily consists of Lactobacillus. Therefore option A is correct.
Lactobacillus species are the predominant bacteria in the healthy adult vagina. They play a crucial role in maintaining a slightly acidic pH, which helps prevent the overgrowth of harmful microbes.
Lactobacillus produces lactic acid, creating an inhospitable environment for many potential pathogens. This microbial balance is essential for vaginal health and helps protect against infections.
2. Cystitis, which is inflammation of the bladder, is most often caused by Escherichia coli. Therefore option A is correct.
Escherichia coli (E. coli) is the most common causative agent of cystitis. It is a bacterium that normally resides in the intestines.
However, when E. coli enters the urethra and travels up to the bladder, it can cause an infection. Cystitis is more prevalent in females due to their shorter urethra, which provides easier access for bacteria to reach the bladder.
3. Pyelonephritis, a more severe infection involving the kidneys, may result from: All of the answers are correct. Therefore option E is correct.
Pyelonephritis can result from various routes of infection, including urethritis (inflammation of the urethra), cystitis (inflammation of the bladder), and ureteritis (inflammation of the ureters).
Additionally, it may also occur as a complication of systemic infections, where bacteria from other parts of the body spread to the kidneys via the bloodstream.
4. The following is NOT primarily a sexually transmitted infection (STI): Neisseria gonorrhoeae. Therefore option D is correct.
Neisseria gonorrhoeae is a bacterium responsible for the sexually transmitted infection known as gonorrhea. Therefore, it is indeed primarily a sexually transmitted infection (STI).
In summary, the normal vaginal microbiota is mainly composed of Lactobacillus species. Cystitis is most often caused by Escherichia coli, and pyelonephritis can result from various routes of infection.
Neisseria gonorrhoeae is a sexually transmitted infection, making it different from the other listed pathogens.

Some human cells can perform anaerobic respiration for limited amounts of time, such as during periods of heavy exercise. Use the results of your experiment to explain how anaerobic respiration could benefit human survival.
Answers
Answer:
My experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.
Explanation: from plato, so change it a bit.
The experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present.

The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.
What is anaerobic respiration ?Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.
In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is an excellent electron acceptor. Anaerobes instead use less-oxidizing substances such as nitrate (NO−3), fumarate (C4H 2O2−4), sulfate (SO2−4), or elemental sulfur (S). These terminal electron acceptors have smaller reduction potentials than O2. Less energy per oxidized molecule is released. Therefore, anaerobic respiration is less efficient than aerobic.

why is sexual reproduction a necessity for sharks
Answers
Answer:
cause they can't asexually reproduce
Explanation:
a shark has to reproduce and is too big of an organism to use asexual reproduction, so there's only one left
Cells that live in environments where oxygen is present only a small amount of the time have two options to survive. They can be obligate anaerobes, which are poisoned by oxygen and do full cellular respiration with an electron transport chain that ends in a different molecule than oxygen (such as sulfur.) Alternatively, they can be facultative anaerobes that do full cellular respiration with oxygen when oxygen is available but do fermentation with glycolysis when oxygen is not available. Full cellular respiration makes 32 ATP per glucose. Glycolysis makes only 2 ATP per glucose. Write out which option you think is better in an environment that only occasionally (rarely) contains oxygen, obligate or facultative anaerobe, and defend your answer.

by defending the answer is that aerobic respiration is used by oxygen but anaerobic respiration is not used by oxygen also plants they do survive at night but human being cannot breathe the same air with plants at night because oxygen take place but at the daytime we use carbon dioxide this is how I do understand in my understanding

Answers
Answer: A. neither can be accepted as correct because muscles growth is difficult to study in humans.
Explanation:
Hypertrophy can be defined as the increase in the fiber size of the muscle whereas the hyperplasia can be defined as the increase in the number of muscle fibers. Additionally the hypertrophy suggests that adding more proteins to the fibers is suggestive of the growth of the muscles. But these two theories cannot be directly related to the muscle growth in humans as the development and growth of muscles are dependent upon several factors like diet, any kind of disease which restrict the muscle growth and movement, physical activities, mineral availability responsible for growth, malnutrition, and others.

D) The introduction of a new predatory species to an island by boat.
Answers
_____________
The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.
What is species?Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.
In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.
But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.
Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

O an increase in the amount of water available for recreational use
an increase in the destruction of natural food webs
O a decrease int he amount of water needed by industry
Answers
Answer:
The correct answer would be - an increase in the destruction of natural food webs.
Explanation:
Increasing chemical industries near the river cause harmful effects to the environment by various means, including air pollution, dumping untreated chemical or industrial waste, and wastewater in the river. This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.
The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.
