C) Antibiotics could cure chicken pox sooner than 7 days, since it is a virus. D) The immune system of a person gets chicken pox under control in about 7
Answer:
C) Antibiotics could cure chicken pox sooner than 7 days, since it is a virus.
Explanation:
Antibiotics can only be used to treat bacterial diseases.
Chicken pox is one of the most common childhood diseases. Caused by a virus (which explains why it cannot be treated with antibiotics), it can be highly contagious for those who have never had it before or those who have not received the vaccine. However, once exposed to the disease, the person is immune for the rest of his life.
Chicken pox is mainly characterized by the appearance of red blisters on the skin, scattered throughout the body, which cause itching and other symptoms.
According to friedrich, when food and fluid intake is poor, starvation occurs before dehydration
The statement of Liz Friedrich is verified by evidence from research of a physiologic adaptation, during the vanishing development, the famine that averts any uneasiness as a outcome of the absence of food. Dehydration may result to hemoconcentration and hyperosmolality, with consequent azotemia, hypernatremia, and hypercalcemia. These metabolic fluctuations may create a soothing effect on the brain before passing away.
What is the water cycle and how does the Conservation of Matter apply to the water cycle?
The water cycle is the continuous movement and recycling of water through different states and locations on Earth, without any loss or gain of water molecules, in accordance with the law of conservation of matter. The law states that matter cannot be created or destroyed, which is essential in chemistry and is exemplified by the constancy of matter within the water cycle.
What is the Water Cycle?
The water cycle, also known as the hydrologic cycle, is the continuous movement of water on, above, and below the surface of the Earth. Water molecules travel through different states: gas (water vapor), liquid (water), and solid (ice). The main processes in the water cycle include evaporation, transpiration (from plants), condensation (forming clouds), precipitation (rain or snow), infiltration, and runoff.
Law of Conservation of Matter
The law of conservation of matter states that matter is not created or destroyed in a chemical reaction. This universal law also applies to the water cycle. As water transforms through various states and moves throughout the ecosystem, the amount of matter (water molecules) remains constant. This demonstrates that the water you drink has been a part of the Earth's water cycle for potentially millions of years, undiminished in quantity.
How Conservation of Matter Applies to Chemistry and the Water Cycle?
In chemistry, the law of conservation of matter is fundamental, indicating that the total number of atoms, and thus the mass of all reactants, is equal to that of the products in a chemical reaction. Relating to the water cycle, this law ensures that water molecules, despite changing states or location, are neither lost nor gained overall during the process. All matter, or water in this context, is perpetually recycled within the Earth's system.
________ is the five-carbon sugar found in DNA.
Answer:
Deoxyribose is the five -carbon sugar found in DNA.
Explanation:
The molecule of DNA is composed of nucleotides. The nucleotides are units composed by a phosphate group, a nitrogenous base and a molecule of the carbohydrate deoxyribose.
The deoxyribose is a pentose sugar. Four carbon atoms and a single atom of oxygen form a five membered ring. The other carbon atom is outside the ring and forms a part of a CH2 group.
It contains a five carbon carbohydrate ring bound to the phosphate group, on its other side, the deoxyribose is bonded to a nitrogenous based: Adenine, Thymine, Cytosine or Guanine.

Why do you think that the catalase protein has persisted over time in so many organisms?
Final answer:
Catalase has persisted over time in many organisms because it enables them to detoxify hydrogen peroxide, protecting cells from oxidative damage. This enzyme's widespread presence across species emphasizes its critical role in cellular defense and metabolism, underlining the evolutionary advantage it provides in managing reactive oxygen species.
Explanation:
The catalase protein has persisted over time in many organisms due to its essential role in protecting cells from the harmful effects of hydrogen peroxide, a byproduct of various metabolic processes. Catalase converts hydrogen peroxide into water and oxygen, thereby preventing potential damage to cells. This enzyme is not only involved in detoxifying hydrogen peroxide but also has the capability to oxidize a wide range of organic compounds, albeit at a much lower efficiency. The persistence of catalase can be attributed to its evolutionary advantage, allowing organisms to thrive in oxygen-rich environments. Furthermore, the enzyme's presence across numerous organisms highlights its fundamental role in cellular protection and metabolism. Despite the varying levels of catalase in different species, its existence is a testament to the evolutionary pressures favoring organisms capable of managing reactive oxygen species effectively.
It's also interesting to note that organisms have developed additional mechanisms, such as peroxiredoxins, to cope with lower levels of catalase, indicating a complex interplay of evolutionary adaptations aimed at ensuring survival in reactive oxygen species-rich environments. The persistence and evolution of catalase across diverse species underscore its critical role in cellular defense against oxidative damage.

Explain why atmospheric concentrations of carbon dioxide are expected to increase in the future.
The atmospheric concentrations of carbon dioxide are expected to increase in the future because of increasing numbers of vehicles as well as industrial area.
How automobiles and industries affect the atmospheric concentrations of carbon dioxide ?All the industries, automobiles and other sources of carbon , releases large amount of carbon dioxide which further accumulate to increases the concentration of CO2 in the atmosphere.
Enhanced carbon concentration in the atmosphere restricts the escape of heat from the earth (Green house effect) thereby increasing the temperature of earth. Thus, first the carbon dioxides is released, then its concentration increases and lastly the global temperature rises.
Thus, increasing numbers of vehicles as well as of industrial area is the main concern.

What is the main component of the thin filaments in muscle fibers and is responsible for muscle contraction?
Answer:
Actin Protein
Explanation:
Protein named “Actin” is the main component of thin filament in muscles. There are some other proteins such as troponin and tropomyosin that forms the thin filament. However, actin plays an important role in the contraction of muscles as each actin molecule consists of single myosin binding site. All actin molecules join together to form a chain twisted into helix configuration which is very essential for the contraction mechanism in muscles.

The process that removes metabolic waste products from an organism is known as
The process that removes metabolic waste from an organism is called excretion. In humans, the kidneys play a crucial role in this process while other organisms have their unique systems like vacuoles, flame cells, and Malpighian tubules. These systems essentially maintain a balanced internal environment by expelling metabolic waste, such as ammonia, urea and uric acid.
Explanation:The process that removes metabolic waste products from an organism is known as excretion. The human body has a complex system, which primarily involves the kidneys, to filter waste from the bloodstream and excrete it in the form of urine. On the other hand, succinct organisms and invertebrates utilize more simplistic systems, such as vacuoles, flame cells, and Malpighian tubules.
Microorganisms use contractile vacuoles, while flame cells and nephridia are used by worms for waste excretion and osmotic balance. Insects have evolved Malpighian tubules for the same purpose. These systems remove metabolic wastes and other substances from the body, maintaining a balanced internal environment.
The waste product of the metabolism of nitrogen-containing compounds, such as proteins and nucleic acids, is ammonia. Aquatic animals easily excrete ammonia into their surroundings, but terrestrial animals have evolved special mechanisms for removing this toxin. For vertebrate animals, urea is the primary byproduct of ammonia metabolism, while birds, terrestrial arthropods, and reptiles primarily produce uric acid.

egg laying land animals have evolved to produce eggs with tough shells to ensure that
Answer:
To ensure that no drying of the embryo occurred.
Explanation:
Because of the inhospitable environment, eggs from terrestrial animals that had a thinner shell were very susceptible to desiccation of the embryo. This made it difficult for the species to continue because it caused the embryo to die and did not allow a new being to be generated.
Over time, as a way of overcoming this disadvantage, some of the land animals had evolved to make thick-shelled eggs. The egg of these animals has a thick shell that prevented the drying of the embryo. However, the shell was porous, allowing gas exchange between the embryo and the external environment, thus ensuring the survival of the species.
