Maturation of sperm or ova
Stimulation of sex (gonadal) hormone secretion
Maintenance of structure of the gonads
These hormones have 3 primary effects on the gonads: in males sometimes known as interstitial cell stimulating hormone (ICSH)
Insulation and metabolites
CT has a good nerve supply and is highly vascular (except cartilage and tendons). Blood
vessels supply nutrients and oxygen and remove waste from tissues. CT suppl
An acyl group carrier
Referred to as CoA
Written in equations as CoA-SH as the thiol group is the reactive part
Carries acyl groups as thiol esters (high energy compounds)
Pass from the cytosol of the cell into the mitochondrion (via membrane
Evolution and development
Biological diversity - evolution+development
phylogenetic trees - express relationships between organisms
different body plans+but common traits - share common ancester
greater - evolutionary distance between organisms - great

Conservation Biology- Lecture 2 GLOBAL
PATTERNS AND PROCESSES
The world comprises an enormous variety of habitats and ecosystems
The number of which and their topographic complexity is one measure of the ecological
diversity in a regio
Conservation Biology- Lecture 5 Role of Animal
Behaviour in Conservation Biology
Endangered species: is living in a small population a bad thing?
Endangered populations are small
Small populations are at greater risk of extinction

Define nuclear fission
Define nuclear reaction
Reactions in which an atoms nucleus splits
into smaller parts (and 2/3 neutrons) releasing
a large amount of energy in the process.
It can be spontaneous, or occur when the
nucleus of a heavy atom captures a
Carbohydrates Cell Biology
What are Carbohydrates?
The most abundant biomolecules on earth
Photosynthesis: >1 x 1011 tons (100 billion tons) of CO2 and H2O into cellulose and other
Carbohydrate polymers: structural and protective elements i
Lecture notes on Connective Tissue
The five types of connective tissue
Functions and properties of connective tissue
Connective tissue provides support and strength, while protecting and insulating.

Right ventricle pumps deoxygenated blood to the lungs where it receives oxygen.
The oxygenated blood then returns to the heart to be pumped a second time ( by the left ventricle) out to the

2.1 Nucleic acids the molecules of life
Nucleic acids information molecules of the cells form new cells stored in chromosomes in
nucleus of the cell in the form of a code in DNA / parts of the code are copied into RNA then to
another form used to make p
The basics of genetics
mutations mistakes in transcription / translation
phenotype physical/chemical characteristics that make up the appearance of an organism

Topic 1: Lifestyle, health and risk
Explain the importance of water as a solvent in transport, including its dipole nature.
Distinguish between monosaccharides, disaccharides and polysaccharides (glycogen and starch amylose
and amylopectin) and relate t
2.4 In-depth study of a genetic diseases - Cystic fibrosis
Cystic fibrosis is an inherited disorder that mainly affects respiratory, digestive and
reproductive systems. It is caused by a recessive allele so a person will only have
the disorder if theyre
2.3 Transport across membranes
membranes include those that surround the organelles and the cell surface membrane
the cell surface membrane (outer cell membrane) forms the boundary of the cell where
anything that leaves or enters must p
Surface area to volume ratio
Mass transport systems: have branching vessels, make sure of ideal substance direction and movement and have a medium.
Dipole: slight separation of charge between oxygen and hydrogen atoms.
There are weak bonds b
In small unicellular organisms, substances move around slowly by diffusion.
Diffusion is too slow to move substances round the larger bodies of multicellular
They have a circulatory system: substances are carried in blood pumped by a hear
