Question

characteristic description cells organisms are made of one or more cells. a cell is a tiny, organized structure that is surrounded by a thin covering called a membrane. a cell is the smallest unit that can perform all life functions. homeostasis organisms maintain homeostasis, or constant conditions inside their bodies, even when conditions outside their bodies change. metabolism organisms carry out many chemical reactions to obtain energy. organisms use energy to grow, to move, and to process information. metabolism is the sum of all the chemical reactions carried out in an organism. responsiveness in addition to maintaining a stable internal environment, living organisms also respond to their external environment. reproduction most organisms can reproduce. reproduction is the process by which organisms make more of their own kind. heredity when an organism reproduces, it passes on its own characteristics, or traits, to its offspring. this is called heredity. inherited characteristics change over generations. this process is called evolution. growth all living organisms grow. as organisms grow, many change. this process is called development. development differs from evolution because development refers to change in a single individual during that individuals life. critical thinking 1. infer give one example of an internal condition in your body that remains fairly constant over time. 2. explain why do helpful traits tend to become more common in a species over time?

Explanation:

1. Body temperature is an internal condition that remains fairly constant (around 37°C or 98.6°F in humans) due to homeostasis mechanisms. For example, when it's hot outside, we sweat to cool down and when it's cold, we shiver to generate heat.
2. Helpful traits tend to become more common in a species over time because organisms with these traits are more likely to survive and reproduce. This is based on the principle of natural - selection. Organisms with advantageous traits have a higher fitness and pass on these traits to their offspring, increasing the frequency of the helpful traits in the population.

Answer:

1. Body temperature
2. Because organisms with helpful traits are more likely to survive and reproduce, passing on these traits to offspring.
