Which of the following is an example of an organism maintaining homeostasis? A.
a boy riding a bike
B.
a cat grooming itself
C.
a bear nursing her cubs
D.
a man sweating while he runs
Answers
Homeostasis is generally maintained by an organism inside the body. Option D is the best example of the given statement.
How do organisms maintain homeostasis?
The state which maintains the physical, chemical and internal condition inside the body by the living system is called homeostasis. This is the condition at which an organism functioned optimally which includes body temperature and blood sugar.
In other words, homeostasis is the tendency of the body to monitor and maintain its internal states up to a stable level.
Option D states that "A man sweating while he runs". It means that when a man runs, his body itself maintains its temperature and the heat energy generated during the movement of the body is converted into a sweat. Thus the man started sweating while the body temperature increases.
Hence we can conclude that option D is an example of an organism maintaining homeostasis.

Answer:
Independent variable: washer detergent
Dependent varaible: cleaing power of effectivenes of the detergent.
Explanation:
When an experiiment is performed there exists one independent variable, one dependent variable, and some other variables that must be controlled.
The goal of the experiment is to test a hypothesis, which is a statement that relates an effect with a cause and that must be proved true or false.
The effect in the dependent variable, and the cause is the independent variable.
Jenny (the scientist) wants to show how an effect or phenomenun, the dependent variable, is explained by the explanatory, independent, variable.
In the stated experiment, Jenny wants to know how the effectiveness of a new brand detergent and an old one compare with each other. Therefore, she designs a test in which she will determine how the brand of detergent may explain (explanatory or independent variable) the cleaning power or effectiveness, the dependent variable.
Jenny only can manipulate the independent variable and observe the effect on the dependent variable.
To be conclusive, other variables must be controlled, like the fabric and the amount of dirt of the t-shirts.

m = 1kg, v = 30m/s
Kinetic Energy = (1/2) * 1 * 30 * 30 = 450 J
Answer: 450 J
Explanation:
Kinetic Energy = 1/2 × mass × velocity²
Kinetic Energy = 1/2 × 1.0 Kg × 30 m/s²
Kinetic Energy = 1/2 × 1.0 Kg × 900
Kinetic Energy = 450 J

Answer:
the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.

Answer:
The muscles can perform 320 J of work.
Explanation:
Let the work performed by the muscles be J.
Efficiency of a body is given as the ratio of useful work to that of work supplied.
Here, the work provided by the candy bar is,
Efficiency of the muscles is,
Now, we know that,
Therefore, the work performed by the muscles is 320 J.
