DEFINE EVOLUTION 🦁🐱😱
THE CUMULATIVE CHANGE IN HERITABLE CHARACTERISITCS OF AN ORGANISM'S POPULATION OVER TIME.
TRUE OR FALSE:
ORGANISMS WITH A HIGHER FITNESS ARE MOSTLY LIKELY TO SURVIVE INTO ADULTHOOD AND THEREFORE REPRODUCE TO PASS ON THE MORE BENEFICIAL CHARACTERISTCS TO THEIR OFFSPRING 🐫🐫🐪🐪🐪🐪
TRUE
WHICH IS THE ONLY COUNTRY TO HAVE GONE THROUGH THE MOST FLAG CHANGES AND WHEN WAS THE MOST RECENT CHANGE?
AFGHANISTAN- THE MOST RECENT CHANGE WAS ON THE 15TH OF AUGUST 2021

AN ERROR THAT OCCURS WHEN THE DNA IS COPIED DURING CELL DIVISION!

WHAT ANIMAL DID DARWIN USE TO COME UP WITH THE THEORY 🐱🐱🦁🦁🦁🦁
FINCHES/TORTOISES!!!!!

DOES NATURAL SELECTION PRODUCE A CHANGE IN INDIVIDUALS OR POPULATIONS?

WHY IS BIODIVERSITY AT A GENE LEVEL IMPORTANT?!🌲🌳🌴🏝️🎄
IT ENSURES THAT THE SPECIES ARE SAFEGUARDED WHEN THE ENVIRONMENT CHANGES, DUE TO SOME TRAITS BEING MORE FAVOURABLE THAN THE OTHERS!!!!👱👱👱👱👱👱💃💃💃💃💃💃🧬🧬🧬
( ͡• ͜ʖ ͡• )( ͡° ͜ʖ ͡°)( ͠° ͟ʖ ͡°)
WHAT IS NATURAL SELECTION??!!!😱🫨👖
THE PROCESS WHEREBY ORGANISMS WHICH ARE BETTER ADAPTED TO THEIR ENVIRONMENT WILL SURVIVE AND REPRODUCE MORE OFFSRPING. KEY PROCESS THAT BRINGS OUT EVOLUTION.
TRUE OR FALSE:
EVOLUTION RESULTS IN THE DEVELOPMENT OF A NEW SPECIES. ✅❌
TRUEEE!!!!!
WHAT WOULD LIKELY HAPPEN TO A POPULATION OF AN ORGANISM THAT DID NOT HAVE ADVATGEOUS TRAITS THAT ALLOW THEM TO CONTINUE SURVIVAL AND REPRODUCTION, DESPITE ENVIRONMENTAL CHANGE?🦕🦕🦕🦖🦖🦖🦖🦖🦖🦖🦖🐟🐟🐟🐟🐟
THEY'D EVENTUALLY BECOME EXTINCT.

✨✨WHAT ARE THE 3 LEVELS BIODIVERSITY EXISTS AT??!!!!!✨✨
- SPECIES🙈🙉🙊🐵
- GENE👖👖👖👖👖
TRUE OR FALSE:
THE DIFFERENT SPECIES OF FINCH ON THE GALAPAGOS ISLANDS CAN BE INTERBRED.
FALSE!!!! 🕶️🕶️🕶️🕶️❌❌❌❌❎❎❎❎
HOW DID THE FINCHES AT GALAPAGOS ISLAND EVOLVE INTO DIFFERENT FINCHES?
🐔🐔🐔🐔🦆🦆🦆🦆🦅🦅🦅🐓🐓🐓🐓🦢🦢🦢🐥🐥🐥🐥🐦🐦🐦🐦🐤
THEY MIGRATED OUT TO THE ISLANDS FROM THE MAINLAND AND CHANGED TO SUIT THEIR DIFFERENT ENVIRONMENTS OVER MANY GENERATIONS.
WHY IS IT INCORRECT THAT NATURAL SELECTION INVOLVES ORGANISMS WANTING TRAITS THAT PREFERABLE?
🦒🦒🦒🦒🦒🦒🦒🦒🦒🦒
BECAUSE WE CAN'T FPRCE OURSELVES INTO ADAPTATION, AND IT OCCURS OVER TIME THORUGH GENES, MUTATIONS AND RANDOM CHANCE.
BRIEFLY EXPLAIN WHAT HAPPENS WITH GENES WHEN ORGANISMS REPRODUCE SEXUALLY AND ASEXUALLY?!!!!🫨😱😱🫨🫨🫨😱😱🫨🫨🤦
SEXUALLY:
- THE MALE AND FEMALE GAMETES COMBINE IN MEIOSIS , RESULTING IN UNIQUE ORGANISMS DUE TO DIFFERENT GENES BEING CARRIED DOWN AND INHERITTED.
ASEXUALLY:
- MITOSIS/BINARY FISSION PRODUCES IDENTICAL ORGANISMS BECAUSE DNA IS COPIED EXACTLY FROM ONE GENERATION TO THE NEXT.
WHAT IS SELECTIVE PRESSURE?
any external environmental or biological factor that reduces or increases an organism's reproductive success, driving natural selection
WHAT ARE THE 4 MAIN PRINCIPLES THAT DARWIN PROPOSED FOR EVOLUTION BY NATURAL SELECTION?
( ͠° ͟ʖ ͡°)( ͠° ͟ʖ ͡°)( ͠° ͟ʖ ͡°)( ͡• ͜ʖ ͡• )( ͡• ͜ʖ ͡• )( ͡• ͜ʖ ͡• )( ͡• ͜ʖ ͡• )
( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)
-VARIATIONS OF PHENOTYPES
-TRAITS MUST BE HERITABLE
-"STRUGGLE FOR EXISTENCE"(ORGANISMS HAVE MORE OFFSPRING THAN RESOURCES)
-SURVIVAL AND REPRODUCTION RATES
EXPLAIN WHETHER AN ORGANISM WITH HIGH FITNESS IN ONE ENVORNMENT HAS HIGH FITNESS IN ANOTHER ENVIRONMENT
🤡🤡🤡🤡😷😷😷😷🥸🥸🥸🥸
Not necessarily. An organism with high fitness in one environment will not necessarily have high fitness in another environment due to the fact that its fitness is better adapted for its current habitat, and changes in this environment maybe be detrimental to fitness.
