Front

What are the two types of feedback systems that help organisms maintain homeostasis?

Back

Positive feedback and negative feedback.

Front

What is positive feedback?

Back

Positive feedback is a process that amplifies a response or increases the output in a system, often leading to a specific outcome, such as blood clotting.

Front

What is negative feedback?

Back

Negative feedback is a process that counteracts a change in a system, helping to maintain stability, such as regulating body temperature.

Front

What is the role of platelets in blood clotting?

Back

Platelets release hormones that signal more platelets to come to the site of a cut, forming a clot to stop bleeding.

Front

What structure is common to both plant and animal cells?

Back

Mitochondrion.

Front

What is the function of mitochondria?

Back

Mitochondria are the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

What phase of meiosis is characterized by the separation of homologous chromosomes?

Back

Anaphase I.
