Points shown in ( )Slide2

TRUE/FALSE: Elderly people have more taste buds than younger people…

Question 1

Contributed by The Physiology Society

FALSE

Children

have the most taste buds, which may explain why they are more sensitive and tend to be

fussier about what they eat.

(1)Slide3

Question 2Which is the largest part of the human brain –

the cerebrum/cerebral cortex or the cerebellum?

The cerebrum/cerebral

cortex

This part is further divided into four lobes and is associated with ‘higher’ brain functions such as memory, speech, problem solving, emotions, orientation and recognition.

(1)Slide4

Which animal uses the ‘waggle dance’ as a form of communication?

Cat

Honey bee

Elephant

Ladybird

Eel

Question 3

Biology Challenge

Answer: b) Honey bee

It

uses a complicated, choreographed routine in order to share information and even specific directions to hive members as to the location of a food source or potential nest site.

Question 4

Answer: c) Spider

There are about 40,000 known species of spiders in the world.Slide6

What is the scientific study of plants known as?

Question 5

Botany

Botanists

currently study around 400,000 species of

plants

worldwide and botanical research has wide-reaching implications for food production, forestry, construction and environmental management.

(1)Slide7

 What do a fruit

fly, a worm, a

bacterium,

a mouse and a

frog all have in common?

Question

6Contributed by the Biochemical SocietyThey are examples of 'model organisms' - creatures that biologists use to study how cells work.

Model

organisms tend to be easy to genetically manipulate, have a sequenced genome, have a short lifespan and

are usually small

and cheap to care for

.

(Also accept - they have DNA eukaryotic cells

).

(1)Slide8

What is the normal internal body temperature of a human

?

Question 7

35

°

C

37 °C 39 °C

Answer: b)

37.0 °

C

The

average internal body temperature of a person varies during the day by about 0.5 °C and can change according to the time of day, activity levels and whether the individual is

tired,

sick, hungry or cold.

Who discovered penicillin, and how?

Contributed by the Biochemical Society

Question 8

Alexander

Flemming

He

accidently discovered penicillin in 1928 when he noticed a mould growing on a agar plate culture that had a bacteria-free circle around it, indicating its inhibitive properties. It was the work of Howard Florey and Ernst Chain who developed mass production of penicillin as a drug.

The

three shared the 1945 Nobel Prize

in ‘Physiology

or

Medicine’.

DNA contains two strands that wrap round each other in a double-helix.

Does normal DNA

spiral round to the right or

left as you look down it?

How many years ago did thedodo go extinct?

Question 14

350 years

ago

Evolving

without the presence of predators, the dodo was fearless of humans and unable to fly.

As such it was easy prey when humans arrived on the island of Mauritius, the location to which it was endemic.

Virus

Bacterium

Cell

Contributed by the Society

for Applied Microbiology

Question 15

Which of the following cannot be seen under a light microscope?

Answer: a) Virus

Light

microscopes

use

visible light and a series of lenses in order to magnify a sample and observe finer detail not detectable to the naked eye.

Light

microscopes cannot detect viruses as these microscopic organisms are smaller than

the

wavelength of visible

light.

Where are

blood

cells made?

Question 16

Contributed by The Physiology Society

Bone marrow

Bone marrow

contains hematopoietic stem cells, which can differentiate into three classes of blood cells.

White

blood cells (leukocytes) which are involved in the body’s immune response to pathogens, red blood cells (erythrocytes) which supply the body with oxygen and platelets (thrombocytes), involved in the clotting process, are all formed from bone marrow.

A

type of red seaweed called

Chondrus

crispus

is found in toothpaste.

Question 19A jellyfish is composed of how much water?

35%

65%

95%

(1)

Answer: c)

95

%

Only

5% of a jellyfish is made up of solid matter, the rest

is

water

.

Composed

of three simple layers and a basic nervous system in the form of a nerve net, the jellyfish is seemingly graceful and beautiful in the water, responding to stimuli in their environment such as light.Slide21

Which animal would Sir David Attenborough most like to be? Seahorse

Sloth

Slow worm

Siberian tiger

Salamander

Question 20

(1)Answer: b) Sloth

In a

Royal Society of Biology

interview,

when asked this question, Attenborough replied a sloth, so he could enjoy “hanging around upside down, wanting nothing but another chew on a leaf”.
