Answer:
Las células procariotas están rodeadas por una membrana plasmática y al igual que las células eucariotas tienen ADN, citoplasma y ribosomas. También tienen paredes celulares y pueden poseer una cápsula celular. Los procariontes tienen un solo cromosoma de gran tamaño, que no está rodeado por una membrana nuclear.30-Jan-2013
Answer:
b plants take carbon dioxide from the air
Answer:
ribosomes and cell membrane
Explanation:
Prokaryotes are not allow to have nucleus. They have free roaming DNA, so only ribosomes and cell membrane can be both.
Dad: TtBb
Mom: ttbb
You have to use distribution for dihybrid crosses. Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait. So for example with Dad, I will number the traits:
T(1)t(2)B(3)b(4)
To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb. Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.
Cross:
tb
TB TtBb
Tb Ttbb
tB ttBb
tb ttbb
The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue
