they have an increased capacity to loose water by sweating

they have a significant amount of brown adipose tissue

they are unable to shiver

they have a high body weight/surface ratio

it has many mitochondria

its mitochondria contain a specialised protein that allow reversible disruption of control of oxidative phosphorylation

it is brown because it contains large amounts of cytochromes which are present within the mitochondria

it contains large amounts of glycogen which is used as a source of fuel

atp synthesis and electron flow stop and proton gradient collapses

atp synthesis stops, the proton gradient collapses, and energy from electron flow is released as heat

atp synthesis continues, the proton gradient increases, and the increased work load required to pump protons from the matrix to the intermembrane space results in heat generation

atp synthesis continues, proton gradient collapses and energy from electron flow is released as heat

it does not usually involve any underlying pathological problem

it is more likely to occur in premature and breast fed infants

billirubin may reach toxic levels

it typically invloves an increase in the concentration of conjugated billirubin in the blood

billirubin produced from haem breakdown- it goes to the liver -absorbed by liver cells- conjugation - released into bile - arrives in the gut- deconjugation- gut microbes break it down/ reuptake into the blood via the enterohepatic circulation

Bilirubin produced from breakdown of haem  conjugation  transfer to the liver  uptake by liver cells  deconjugation  release into bile  arrival in gut  metabolism by gut microbes and retention in the gut or re-uptake into the blood via the enterohepatic circulation;

There are different forms of the hormone

It can be secreted in both sexes

It is a glycoprotein based hormone.

Its concentration fluctuates monthly and through the life span

cannot be controlled

has a limited psychological significance in childbirth

is originated from nociceptors in the endometrium

could be measure objectively using a visual analogue scale

Retain the same staining qualities as before pregnancy

Respond to oestrogen with a decrease in size

Increase in size and change shape

Do none of the above

decrease in oestradiol concentration

No change and the pregnancy will be maintained

A rapid fall in serum progesterone

Release of relaxin

all of the above

Breast development

Relaxation of ligments

Enlargement of uterus

50% of the population aged 85 years and over are affected by the disease.

Limited effectiveness of cholinergic agents in its treatment was found

It is recognized now as a “disease"

Lesions are confined to the hippocampus

It is based on the concept that the free radicals harm cells

if a worm is fed antioxidants its lifespan will be prolonged;

It is also called the mitochondrial theory of ageing;

Unlike CO2, oxygen will never damage cells with mitochondria

d. Neither a nor b occurs.

a. The cell depolarizes causing the release of sodium ions inside the cell

b. Depolarization stimulates the release of granules that cause changes to prevent entry of other sperm;

c. Both a and b occur

c. Produces gap junctions between myometrium cells in uterus

a. Inhibits production of oxytocin receptors in myometrium

b. Produces receptors for relaxin

d. Causes both b and c to occur.

b. Prostaglandins

a. Oxytocin

d. All of the above

c. Stretching of the endometrium
