Answer:
Okay let me break this down, so you have a pure red and pure white feathered chicken meaning that the chickens have homologous alleles. Overtime, as you breed the two you may get multicolored chickens but they can carry the recessive white feathers alleles (FWFW) meaning that they can still produce all white chickens and they can continuously do that over generations. Selective breeding may be negative because you may not get the desired result, you could breed for the wrong traits, other characteristics are lost and the resulting population is very similar. Less genetic variation can cause the chickens to not be resistant to problems like diseases and could fall ill.
Explanation:
Answer:
a) because after the cleavage of the phosphate groups, the phosphate at the 5´carbon atom is ready to bind the oxigen from the OH- in 3´carbon en the incoming nucleotide
b) The DNA ligase will need an energy source because after removing the RNA, the 5´carbon will not have the three phosphates to be cleaved so that the energy of those unions can be used to catalize the new union
The correct answer is option C
All the animals are Heterotrophs as they cannot perform photosynthesis.
Except some of the sponges, all the animals are heterotrophs as they cannot make their own food(photosynthesis).
Heterotrophs depends on autotrophs or some other organisms for their food.
They are dependent on other organisms for their energy needs.
Answer: Kinetic Energy
Explanation: Thermal energy comes from moving particles, and that’s what Kinetic Energy does, so Kinetic energy would most likely be the answer.
