Answer:
A major change over long periods of time is best described as macroevolution.
Explanation:
Macroevolution would be referring to evolution on a larger scale where populations speciate etc. A, B and C are various forms of speciation and microevolution would be referring to smaller changes in evolutionary patterns e.g. in adaptive or physical traits which may not be deemed 'significant' enough to be considered a speciation event.
Answer:
F1 Generation -
Genotype - GgRr
Phenotype - Green and round
F2 generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled
9: 3:3:1
Explanation:
G represents Green seed color
g represents yellow seed color
R represents round seed
r represents wrinkled seed
Here G is dominant over g and R is dominant over r
F1 generation -
Genotype of true breeding parents will be
GGRR and ggrr
The offspring produced will be -
GgRr
Genotype - GgRr
Phenotype - Green and round
F2 Generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled
9: 3:3:1

Hello fellow army~
According to the Punnett square for this cross, what percentage of offspring is predicted to have blue feathers?
The answer is 50% ♡♡♡

Answer is: coupled transport differs from primary active transport due to the fact that it uses electrochemical potential difference as a direct source of energy.
Primary active transport directly uses metabolic energy (adenosine triphosphate- ATP) to transport molecules across a membrane.
In secondary active transport (coupled transport) there is no direct coupling of ATP, <span>energy derived from the pumping of protons across a cell membrane.</span>
This is an example of dissolution of carbonates.
When carbon combines with minerals, it dissolves carbon. This transforms minerals that contain calcium, magnesium, potassium, and sodium. When rainwater attacks formations of limestone the constituent minerals dissolve and wash away with mildly acidic rainwater.
