what makes a molecule a saturated fat?
A molecule is a saturated fat when it consists of carbon chains having only single bonds between carbons, making it fully 'saturated' with hydrogen atoms. These fats have straight chains, can pack tightly together, and are solids at room temperature.
Explanation:A molecule is classified as a saturated fat when it is a type of simple lipid molecule with a carbon chain bonded to the maximum number of hydrogen atoms possible. This means that each carbon atom in the chain is linked to adjacent carbons by single bonds only, without any carbon-to-carbon double bonds (C=C). Saturated fatty acids comprise these simple lipid molecules and contribute to the molecule's straight chain structure, which allows them to pack closely together. Consequently, saturated fats tend to have high melting points and are typically solids at room temperature.

A sample of an unknown liquid has a volume of 30.0 mL and a mass of 6 g. What is its density? Show your work or explain how you determined this value.
Answer:
Density of liquid having a volume of 30.0 mL and a mass of 6 g is
[tex]0.2 \frac{g}{ml}[/tex]
Explanation:
Density of a substance is given by mass divided by volume
Mathematically it can be represented as
[tex]D = \frac{M}{V}[/tex]
Where D represents the density
M represents the mass and
V represents the volume
Substituting the given values in above equation we get -
[tex]D = \frac{6}{30} \\= 0.2\frac{g}{ml} \\= 200 \frac{Kg}{m^3}[/tex]
Hence, density of liquid having a volume of 30.0 mL and a mass of 6 g is

What role do glucose and oxygen play in cellular respiration?
In cellular respiration, glucose is used as the primary fuel to produce ATP, while oxygen acts as an essential electron acceptor for efficient ATP production. Without oxygen, much less ATP is produced, demonstrating the necessity of both glucose and oxygen in energy metabolism within cells.
Explanation:Role of Glucose and Oxygen in Cellular RespirationDuring the process of cellular respiration, glucose and oxygen play critical roles. Glucose serves as the primary fuel, with its breakdown releasing the energy necessary for the synthesis of adenosine triphosphate (ATP). Oxygen, meanwhile, is crucial for accepting electrons at the end of the electron transport chain, allowing for the efficient production of ATP. Without oxygen, only a limited amount of ATP can be produced through anaerobic pathways.
The Reactants and Products of Cellular RespirationGlucose enters the body from food intake and is transported by the cardiovascular system from the digestive system to the cells. Oxygen is inhaled into the lungs, diffuses into the bloodstream, and is also carried to the cells. In the presence of oxygen, cellular respiration begins with glycolysis, releasing just two molecules of ATP, and culminates in the mitochondria through the citric acid cycle and the electron transport chain. This leads to the production of the majority of ATP, with carbon dioxide and water as waste products.
Comprehensive Cellular RespirationMost steps of cellular respiration, including the final and most ATP-productive ones, occur within the mitochondria of cells. All organisms that require oxygen perform cellular respiration to convert glucose into the usable energy of ATP. The overall transformation during cellular respiration involves the consumption of glucose and oxygen and the release of carbon dioxide, water, and ATP. As a result, cellular respiration is essential for powering various cellular processes across organ systems, notably involving the digestive, cardiovascular, and respiratory systems.
Final answer:
In cellular respiration, glucose is broken down with the help of oxygen to produce ATP, carbon dioxide, and water. Oxygen's crucial role is to serve as the final electron acceptor in the electron transport chain, allowing for efficient ATP production. Without oxygen, the ATP yield would be greatly reduced.
Explanation:
Glucose and oxygen play crucial roles in the process known as cellular respiration, which is the method by which cells convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. Oxygen acts as the final electron acceptor in the electron transport chain, which is necessary for the production of ATP. Without oxygen, the electron transport chain would not function, significantly reducing the amount of ATP produced by cellular respiration.
In the presence of oxygen, glucose undergoes a series of reactions that result in the production of carbon dioxide and water as waste products, and the most importantly, ATP, which is the main energy currency of the cell. Each molecule of glucose, through the process of cellular respiration, can produce a significant number of ATP molecules, which the cell uses for various energy-requiring functions.
Cellular respiration is a multi-step process starting with glycolysis, continuing through the citric acid cycle, and concluding with oxidative phosphorylation at the electron transport chain. This intricate process involves the digestive, cardiovascular, and respiratory systems, as glucose comes from the food we eat, and the oxygen needed for respiration is obtained from the air we breathe.

What are the two main ways that minerals are classified?
Explain the properties of cohesion and adhesion. Give an example of each property.
Final answer:
Cohesion refers to the attractive force between molecules of the same substance, while adhesion is the interaction between molecules of different substances. Examples include water droplets exhibiting surface tension for cohesion and water adhering to wax paper or moving up a thin tube through capillary action for adhesion.
Explanation:
Cohesion and Adhesion Explained
Cohesion is the force that holds molecules of the same substance together. This property is exemplified by droplets of water forming on a surface, such as wax paper; the water molecules remain together, exhibiting the cohesive force. A notable phenomenon related to cohesion is surface tension, which allows certain insects to walk on water without sinking.
Adhesion is the interaction that occurs between molecules of different substances, leading them to stick together. An example of adhesion is when water droplets adhere to a sheet of wax paper, even when turned upside down, showing the attraction between the water molecules and the paper's surface. The effect of adhesion is clearly seen in capillary action, where water can move up thin tubes or through porous materials, opposing gravity.
