A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.

Answers

Answer 1

C.  Yes, because the number of atoms of each element is the same on both sides of the equation.

Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.

Answers

It’s very important because let’s say you’re outside on a hot summer day and you’re sweating a lot, sweat would be to help you cool down but you would be losing water in the process. If you stop sweating but you’re still hot you would sweat out and this would cause a heatstroke

It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.

What is homeostasis?

Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.

This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.

Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.

Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.

It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.

Thus, having an optimum temperature is essential in functioning of enzymes.

What is a lipid that makes up cell membranes and is used to create hormones?

cholesterol**

Cholesterol makes up cell membranes and is used to create hormones.

Cholesterol is a necessary lipid for the body as it contributes to the formation of cell membranes and hormones. However, high amounts of cholesterol in the blood have harmful consequences for health.

Cholesterol has different functions in the body such as:

- Formation of structures: It is one of the main components of the plasma membranes of animal cells.

- Contributes to the formation of hormones: sex hormones (progesterone, estrogens, and testosterone), corticosteroid hormones (cortisol and aldosterone).

- Contributes to the metabolization of calcium to obtain vitamin D.

Additionally, the options hydrocarbon (natural chemical compound obtained from the earth to be used as fuel), starch (natural macromolecule that contributes to the human digestion process) and glucose (the most abundant chemical compound in nature that serves as a source of energy for organisms) are not correct options, because these substances do not have the function of forming cell membranes and creating hormones.

The IQ range that indicates moderate mental *********** is A. 70-79.

What is an IQ?

IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.

The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.

While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.

This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.
