New cards

structural adaptations

  • camouflague

  • cold environment, thick layer of fur

  • tear meat

  • burrows

  • scratch tree

  • signal territory

2
New cards

behavioural

  • bask in sun to absorb heat

  • migrate durin winter

  • play dead

  • courting behaviour

3
New cards

functional

  • desert converse water by producing little sweat

  • brown bears, low metabolism,

  • late implantation of embryos

4
New cards

mycoprotein

  • fungus fusarium, produce mycoprotein, grown in anaerobic conditions on glucose syrup,

  • fungal biomass harvested and purified, produce the mycoprotein

5
New cards

fertilisation

  • produce new cell zygote, develop into embryo, number of cells increase by mitosis, embryo developed, cell begins to differentiate

6
New cards

speciation

  • populations geographical isolated, with different conditions in each area

  • variation in each population due to mutatios

  • organisms compete and ones that are better adapted to survive and reproduce, so advantageous allele are selected, natural selection

  • different alleles advantageous, in different environments

  • selection of different alleles, increase variation, so genetically different, they cannot reproduce to make fertilise offspring
