How have the historic levels of melanin in human populations changed due to migration? (1 point)
Lesson 7: Genetic Variation Over Time Quick Check
might just end up doing the thing myself and posting the answers when im done cuz im bored but answers please!!
These are the answers for Genetic Variation Over Time Quick Check:
1. Humans that produced less melanin became more common as populations migrated away from the equator.
2. The proportion of tortoises with the ability to extend their necks a long distance would increase.
3. The environment changed such that green toads can blend into their surroundings better.
4. more long-beaked hummingbirds
5. The proportion of white-furred rabbits in the population declines.
These are all correct, trust me, 100%, your welcome :)
No they have changed questions the others are the same just the last two they changed.
# 4. Which phrase best describes selective breeding?
Process where individuals in a population have different traits
Process used to develop new organisms with desirable characteristics*
Process where organisms with traits suited to an area survive to reproduce
Process used to develop new environments for organisms
5. Farmers wanted to grow lemons that were less sour. They crossed a true lemon tree with a mandarin orange tree to develop a hybrid sweet lemon tree. What process was used to create the sweet lemon tree?
Melanin
Natural selection
Selective breeding*
Variation
Can someone please check my answers. Thank you.
here are all 5 questions, could get changed later dunno
1. humans that produced less melanin become more common as populations migrated away from the equator
2. the proportion of tortoises with the ability to extend their necks a long distance would increase
3. the environment changed such that green toads can blend into their surroundings better
4. process used to develop new organisms with desirable characteristics
5. selective breeding
should be a 100%
Can anybody clarify these answers? and what is the explanation behind it? I need some help
