<span>Its called Doxycycline-induced esophageal ulcer. Its not common. I have been taking Doxy for many years for acne without any complication. Then one night I took a single pill, drank half a glass of water, and went to bed. I woke up with mild heartburn. A few days later, I was in immense pain. I felt burning up and down my whole chest. I was bloated, gassy, and couldnt burp. The pain was so severe, it caused me have a migrane. The pill dissolved in my esophagus, and caused an ulcer. It was my fault for not drinking a full glass of water, and going straight to bed. Im in treatment now, and am scheduled for an esophagogastroduodenoscopy. Im feeling a little better already after the first day of treatment, but ulcers take 4-8 weeks to heal.</span>

Prokaryotes- lack a cell nucleus, unicellular, in the bacteria and archaea domain, lack mitochondria and chloroplast, microscopic
eukaryotes- contains a cell nucleus, multicellular, only in the eukarya domain, contains mitochondria and chloroplast, not microscopic
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
