When you feel cold, there are sensors in your skin that tell the brain you need to warm up. the brain sends messages, by way of nerves, to the muscles in your body causing them to contract and relax very quickly resulting in a shiver. the movement of the muscles during a shiver generates heat which can be used to warm up the surrounding tissues. which characteristic(s) of life is being represented during this action?

Shivering is one trigger reaction from the brain which causes your muscles contract and expand in speedy bursts as an impulse to warm your body to protect it from illness and hypothermia.

This characteristic of life is known as maintaining a balance inside the body or cells of organisms and called homeostasis.

The answer is D

Explanation: Respond the stimuli and maintain homeostasis  

and after water is usually warmed by the sun the water temperature raises and then evaporates .

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
