Explanation:

Answer: Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

Explanation:

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

Answer:

Explanation:

Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

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. 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.

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.

Answer: it might Be C or B

Explanation:

Answer:

false

Explanation:

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

Carbon can also be harmful because a large amount of carbon is increasing the warmth of the earth. Carbon dioxide gas increases, lowering the pH of the ocean by the process called acidification, which is a threat to Ocean animals.

Carbon is an element or a substance that is present on earth in different forms full stop carbon is present in two forms on the earth, one is black and heart solid and one is gray and soft.

Carbon reacts with another element to produce different compounds, when carbon reacts with oxygen is produced carbon dioxide which is a very harmful gas for the earth and human beings.

Thus, as greenhouse gases are increasing including carbon dioxide the main threat to life and the earth is increasing of temperature which is melting the ocean and high temperature would not be best for all creatures.

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.

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.
