Answer:

A

Explanation:

One example of how a molecule of carbon can move through different biological processes in different organisms is:

Carbon dioxide (CO₂) present in atmosphere

Cellular respiration in a herbivore

CO₂ is present in the atmosphere and is absorbed by plants through photosynthesis in the leaves. This CO₂ is converted into organic compounds such as glucose, which are subsequently stored in plant cells.

A herbivorous animal, such as a cow, consumes the plant and digests the glucose via cellular respiration. The glucose is broken down into carbon dioxide and water during this process, and the generated energy is utilized by the animal for numerous physiological activities. Cellular respiration produces carbon dioxide, which can then be breathed into the atmosphere.

Manure is produced by cows and contains organic stuff such as carbon, nitrogen, and phosphorus. Decomposition occurs when bacteria in the soil degrade manure, releasing carbon dioxide. This carbon dioxide can be taken up by adjacent plants, restarting the cycle.

The topical application of phenylephrine on the nasal mucosa is expected to result in nasal vasoconstriction.

Phenylephrine is a sympathomimetic drug that acts as an alpha-adrenergic agonist. When applied topically to the nasal mucosa, it stimulates alpha-adrenergic receptors on the blood vessels in the nasal passages. Activation of these receptors leads to the constriction of blood vessels, reducing blood flow to the nasal mucosa and causing vasoconstriction.

Nasal vasoconstriction induced by phenylephrine can have several effects. It can help relieve nasal congestion by shrinking swollen blood vessels in the nasal passages. This can result in decreased mucosal edema and improved airflow through the nasal passages. Additionally, vasoconstriction may reduce the production of nasal secretions, providing temporary relief from a runny nose.

The process in the cell cycle that occurs before the nuclear membrane disassembles is the prophase. The cell cycle is the process that cells undergo to replicate themselves, leading to the formation of two daughter cells. The cell cycle has four stages: G1, S, G2, and M. The G1, S, and G2 phases are collectively known as interphase.

The cell undergoes the mitotic phase (M-phase) after the interphase, and this phase involves mitosis and cytokinesis. Mitosis is the process of dividing the nucleus, and cytokinesis is the process of dividing the cytoplasm. The nuclear membrane begins to disassemble during prophase, which is the first stage of mitosis.In the prophase stage of mitosis, the chromatin condenses into chromosomes, and each chromosome consists of two identical sister chromatids that are held together at the centromere.

The centrosomes move to the poles of the cell and begin to produce spindle fibers that attach to the centromeres. The nuclear membrane begins to disassemble, and the nucleolus disappears.The next stage is metaphase, during which the chromosomes line up in the center of the cell. During the anaphase, the sister chromatids separate and are pulled to opposite poles of the cell by the spindle fibers.

During telophase, the spindle fibers disassemble, and the nuclear membrane reforms around the two groups of chromosomes. The nucleolus reappears, and the chromosomes begin to uncoil back into chromatin. Finally, cytokinesis occurs, resulting in the formation of two daughter cells.

Antibiotics are not effective against viruses because they are designed to kill bacteria by targeting their unique structures and processes.

Viruses have different structures and rely on host cells for replication, making antibiotics ineffective against them.

Antibiotics are not effective against viruses because they work by targeting and killing bacteria, not viruses. Antibiotics are designed to attack the specific structures and processes that are unique to bacteria, such as their cell walls or protein synthesis machinery. Viruses, on the other hand, are different from bacteria. They are much smaller and do not have the same structures or processes as bacteria.

Viruses are composed of genetic material, either DNA or RNA, surrounded by a protein coat. They cannot carry out metabolic activities on their own and rely on host cells to reproduce. When a virus infects a host cell, it hijacks the cell's machinery to replicate itself. Antibiotics cannot disrupt this process because they do not target the specific structures or processes that viruses rely on for replication.

Antibiotics are not effective against viruses because they are designed to kill bacteria by targeting their unique structures and processes.

The oxides of the main group metals are basic in nature. They form alkaline solutions when dissolved in water. Similarly, the oxides of main group non metals form acidic solutions when dissolved in water.

P2O5 is an oxide of a main group nonmetallic element in group 15. We expect this oxide to be acidic and form acids when dissolved in water as expected from the chemistry of the group.

Also, BaO is an oxide of barium, a group two main group metal. Hence we expect this oxide to be basic in nature and form alkaline solutions.

Given that Stem Bromelain has an enzymatic activity of 0.542 U/mg, and there are 20 billion bacteria in our teeth. We need to calculate how long it takes to degrade all of the biofilm created by the bacteria.Assumptions and explanations used in the calculation: Assumption: The mass of the biofilm is not given. Therefore, it is assumed that the biofilm's mass is 1 mg, as the enzymatic activity of bromelain is provided per mg. If the biofilm's mass is different, the result will be different.

We know the enzymatic activity of bromelain, which is 0.542 U/mg.We are given that the number of bacteria in our teeth is 20 billion. The biofilm is created by these bacteria. Bromelain is supposed to degrade the biofilm. Therefore, we need to calculate the mass of the biofilm. The mass of the biofilm is assumed to be 1 mg, as the enzymatic activity of bromelain is given per mg.Now we can use the given data to calculate the time required for bromelain to degrade all of the biofilms created by the bacteria.First, we need to find the total enzymatic activity required to degrade the biofilm. The mass of the biofilm is assumed to be 1 mg.Enzymatic activity of bromelain = 0.542 U/mgTotal enzymatic activity required to degrade 1 mg biofilm= 0.542 U/mg × 1 mg= 0.542 UThe total enzymatic activity required to degrade the biofilm created by the 20 billion bacteria is:Total enzymatic activity required= Enzymatic activity per bacteria × Total number of bacteria= 0.542 U/mg × 20 billion= 1.084 × 10^10 UTo find out how long it takes for bromelain to degrade all of the biofilm, we need to know the rate of degradation. The rate of degradation depends on various factors, such as temperature, pH, etc., which are not provided in the question. Therefore, it is impossible to calculate the time required for bromelain to degrade all of the biofilms created by the bacteria without knowing the rate of degradation.

Answer: Narwhals, polar bears, and walruses will be affected the most.

Explanation:

Polar bears: The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.

Narwhals: The Narwhal's Arctic habitat is highly sensitive to climatic changes that result in increased atmospheric and ocean water temperatures. The Narwhal's annual migration from the north in summer to more southerly overwintering habitats exposes them to sea ice which is constantly expanding and receding. Because of the sea ice rapidly decreasing, narwhals could be exposed to new threats and noises.

Walruses: Habitat loss will be exacerbated for walruses by additional climate-change related factors such as ocean acidification, increased shipping and increasing development in the North, including oil and gas extraction, as well as increased disease and contaminant risks. biggest threat facing walruses is the loss of stable sea ice due to climate change. As a result of less sea ice, walrus are changing their behavior. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice itself sustains a rich food web.
