Paper 2

Animal Coordination, Control and Homeostasis is examined in Paper 2, Biology 2.

It covers hormones, endocrine glands and homeostasis, the stages of the menstrual cycle and the roles of oestrogen and progesterone, hormonal and barrier contraception, insulin and type 1 diabetes, and type 2 diabetes and body mass.

Sample questions from Animal Coordination, Control and Homeostasis

Answer each one closed book first, then open the answer.

Hormones, endocrine glands and homeostasis

Which organ lying behind the stomach releases hormones that control blood glucose?

Show the answer
The pancreas.
Hormones, endocrine glands and homeostasis

Name three conditions inside the body that are kept constant.

Show the answer
Body temperature, the concentration of glucose in the blood, and the water content of the blood.
The menstrual cycle and its hormones

Describe what happens to the lining of the uterus between about day five and day fourteen of the menstrual cycle.

Show the answer
It is repaired and grows thicker, building up a layer rich in blood vessels.
The menstrual cycle and its hormones

Which hormone causes the lining of the uterus to thicken, and where is it made?

Show the answer
Oestrogen, which is made in the ovaries.
Hormonal and barrier contraception

Name three ways of giving hormonal contraception other than a daily pill.

Show the answer
By injection, by an implant placed under the skin, or by a patch worn on the skin.
Hormonal and barrier contraception

Give two advantages of hormonal contraception.

Show the answer
It is very effective when used correctly and it does not interrupt sex.
Controlling blood glucose, and type 1 diabetes

Which organ is the body's main store of glycogen?

Show the answer
The liver.
Controlling blood glucose, and type 1 diabetes

How is type 1 diabetes controlled?

Show the answer
By injecting insulin, usually before meals, together with a carefully controlled diet and regular exercise.

The 5 subtopics

One subtopic is one session. Work down the list.

Subtopic	What it covers	Questions
Hormones, endocrine glands and homeostasis	Hormones as chemical messengers carried in the blood to target organs with specific receptors, the pituitary, thyroid, pancreas, adrenal glands, testes and ovaries and what they release, homeostasis and the changes it responds to, and receptors, coordination centres and effectors.	15
The menstrual cycle and its hormones	The length and stages of the menstrual cycle, menstruation, the thickening of the uterus lining and ovulation around day 14, what happens to the lining if the egg is not fertilised, oestrogen from the ovaries thickening the lining, and progesterone maintaining it until its level falls.	8
Hormonal and barrier contraception	How oestrogen and progesterone in hormonal contraception prevent pregnancy, pills, injections, implants and patches, condoms and diaphragms as barrier methods, the advantages and disadvantages of each, and what perfect-use and typical-use effectiveness figures show.	14
Controlling blood glucose, and type 1 diabetes	How the pancreas monitors blood glucose and releases insulin to lower it by storing glucose as glycogen, why levels rise after a meal and fall in exercise, and the cause, onset, symptoms and insulin treatment of type 1 diabetes, including why insulin is injected and doses are matched to meals.	14
Type 2 diabetes and body mass	The cause and risk factors of type 2 diabetes, how it differs from type 1 and is controlled, calculating body mass index and waist to hip ratio and their limits, correlation and cause, and scatter diagrams showing positive, negative or no correlation with lines of best fit.	22

How the guide is worked

Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.

Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.

Read the full method, the return schedule and the research behind it.
