Bio characteristics of life 2.0

what is cycled, energy or nutrients?

Nutrients are cycled through ecosystems, whereas energy flows in one direction, typically entering as solar energy and exiting as heat.

What is the condition involved with the thyroid

Goiter is a condition characterized by an enlargement of the thyroid gland, often due to iodine deficiency or other thyroid dysfunctions.

Are viruses alive?

Viruses are not considered alive because they have no cells, cannot metabolize, cannot reproduce independently, and they cannot maintain homeostasis alone.

What are the levels of organization above organism?

Population is a group of individuals of the same species living in a specific area. community includes multiple populations interacting in a given area. Ecosystem combines living organisms with their physical environment(non-living surroundings)

Example of stimulus response

A stimulus response is an action or reaction that occurs in response to a stimulus, like a plant bending towards light (phototropism) or a human pulling away from a hot surface.

What are the two groups of organisms that either produce food or ingest it?

autotroph is an organism that produces food, while a heterotroph is one that ingests food.

What are the two types of blooded creatures?

Endothermic(warm blooded) have a steady blood temperature, while ectothermic (cold blooded) rely on environmental heat sources for temperature regulation.

When do blood vessels grow versus shrink, and what is that called?

Vasodilation is when it is too hot which radiates heat outside of the body, vasoconstriction is when it is too cold to stop heat from escaping

Other body temperature mechanisms

Shivering generates heat from fast movement, goosebumps trap heat by raising hair follicles, and sweating cools the body through evaporation removing some heat.
