Human cells obtain energy from a reaction called cellular respiration. balance the skeletal equation for cellular respiration. c6h12o6(aq)+o2(g)→co2(g)+h2o(l) express your answer as a chemical equation. identify all of the phases in your answer.
Final answer:
The balanced chemical equation for cellular respiration is C6H12O6(aq) + 6O2(g) → 6CO2(g) + 6H2O(l) + Energy, showcasing the process of converting glucose and oxygen into water, carbon dioxide, and energy in living cells.
Explanation:
The question asks us to balance the chemical equation for cellular respiration, which is a fundamental biological process where cells convert glucose and oxygen into water, carbon dioxide, and energy. The balanced equation for cellular respiration is C6H12O6(aq) + 6O2(g) → 6CO2(g) + 6H2O(l) + Energy. This equation signifies that one molecule of glucose (C6H12O6) reacts with six molecules of oxygen (O2) to produce six molecules of carbon dioxide (CO2), six molecules of water (H2O), and energy, typically stored in the form of ATP (Adenosine Triphosphate).
Cellular respiration occurs in the cells of all living organisms, enabling them to obtain energy necessary for life processes. The glucose and oxygen in the reaction come from food and the air, respectively, reflecting the importance of respiration in energy metabolism. The products, carbon dioxide and water, are expelled from the body as waste materials.

Which characteristic of the genetic code lowers the likelihood of mutation?
Degeneracy of the genetic code is a key characteristic that reduces the negative impact of mutations by allowing similar amino acids to be encoded by multiple codons, which differ by only one nucleotide, thus maintaining protein functionality.
Explanation:Characteristic of the Genetic Code That Lowers the Likelihood of Mutation
One characteristic of the genetic code that reduces the likelihood of mutation having a negative impact is degeneracy. Degeneracy means that multiple codons can code for the same amino acid. Often, these codons differ by only a single nucleotide. If a mutation occurs, changing one of these nucleotides, the amino acid coded for might remain the same, or it might change to a similarly behaving amino acid. This aspect of the genetic code helps maintain protein functionality despite mutations. Additionally, amino acids with similar chemical properties tend to be encoded by similar codons, which further helps to conserve protein structure and function in the event of mutations.
Moreover, the genetic code is unambiguous and universal, which are additional important characteristics that illustrate its robustness. Each codon corresponds to one specific amino acid (or a start/stop signal), and this unambiguity prevents confusion during protein synthesis. The universality of the genetic code across all known living organisms highlights a shared evolutionary origin and ensures consistency in how genetic information is translated into proteins.

A.
energy required by the substrate to fit into the active site
B.
energy supplied by enzymes in a chemical reaction
C.
energy released when reactants combine to become products
D.
energy required to break the chemical bonds of the reactants
Activation energy is the energy required to break the chemical bonds of the reactants in a chemical reaction.
Explanation:The correct answer is D. Activation energy is the energy required to break the chemical bonds of the reactants in a chemical reaction. It is the minimum amount of energy needed for a reaction to occur. Activation energy acts as a barrier that the reactant molecules must overcome to undergo a reaction and form products. For example, when wood is burned in a fire, activation energy is needed to break the bonds between the carbon and hydrogen atoms in the wood and allow them to react with oxygen to produce carbon dioxide and water vapor.

The mark of sexual maturation for a boy that is most comparable to menarche for a girl is
Final answer:
The mark of sexual maturation for a boy that is most comparable to menarche for a girl is spermarche, the first ejaculation, marking a significant milestone in a boy's puberty, usually around 13 to 14 years old.
Explanation:
The mark of sexual maturation for a boy that is most comparable to menarche for a girl is spermarche. Menarche marks the onset of menstruation in girls, typically occurring around the ages of 12 to 13 years old, and signifies a key point in sexual maturation and the ability to reproduce.
Similarly, spermarche, the first ejaculation, represents a comparable developmental milestone in boys, usually happening around 13 to 14 years old. This event indicates that the male's body is starting to produce viable sperm, marking a significant step in sexual maturation.
Both menarche and spermarche are influenced by various factors, including genetics, diet, and overall health, and they signify the body's entry into reproductive capability. While the onset and pace of these developments can vary widely among individuals, they are central components of puberty that signal the maturation of the body's reproductive organs.

A lion stores 100 energy units after eating zebra meat from the trophic level below it. How many energy units did the zebra meat have?
After eating zebra meat from the trophic level below it, a lion stores 100 energy units. Zebra must possess 1000 energy units.
What is trophic levels?An organism's trophic level is the position it holds in a food web. A food chain is a series of organisms that eat other organisms and may be eaten in turn. An organism's trophic level is the number of steps it has taken since the beginning of the chain. A trophic level is a step in an ecosystem's nutritive series or food chain. The feeding behaviour of organisms in a chain is used to classify them into these levels. The producers, or green plants, are found on the first and lowest level. A trophic level is a position or level in a food chain, food web, or ecological pyramid.Therefore,
The 10% rule is being applied. Because Lion stores 10% of its energy, this 10% of energy will be transferred between tropical levels.
