The plant contains eukaryotic cells.
Answer:
Parent 1 : AaBb
Parent 2: aaBb or Aabb
Explanation:
In this cross two genes are involved and they are duplicate genes with cumulative effect i.e. individually they show the same phenotype but when together, they produce a new phenotype. Here,
A_B_ = red
aaB_ = sandy
A_bb = sandy
aabb = white
The progeny in question has a white piglet (aabb) so it must have got a set of "ab" gametes from both parents. Since parent 1 has red phenotype it should also have one A and B allele. Hence its genotype is AaBb.
Parent 2 should also contribute an "ab" pair to white piglet and it has sandy colour which is produced by either an A allele or a B allele so its genotype should be Aabb or aaBb.
Answer:
24 million years
Explanation:
A: GCACTAAGCATCGATTT
B: GCACCAGGCACTGGTTC
There are 6 base pair changes between species A and species B. Since we know the rate of change is 1 base pair every 4 million years, we know 6x 4 million is likely how long ago the species diverged. 6x 4 million = 24 million years
A) plant because it does photosynthesis
You will be able to recover from exercise when you are fit because your body can be more quick and agile and development more to the best of it's abilities it will be stronger and more effective to complete any activities . your body can use it's energy for more important matters instead of it turning into waste . because there will be nothing to hold your body back from using it's full potential.
