Three genes control the production of tail structures in dogs. The wag1 gene promotes the production of tail structures. However
, the brkn gene inhibits wag1 activity. Another gene, ntrdr, stimulates activity of the brkn gene. Put these genes in order in a developmental pathway. Use arrows and t-bars between the genes as appropriate. You conducted an experiment in which you knocked out the activity of the ntrdr gene in early embryological development. Will tail structures be produced by this animal?
a. Yes
b. No
(1)In this experiment three different genes are present;
1) Wag-1 - promotes production of tail structures
2) brkn gene - inhibits Wag-1 which leads to inhibition or inactive Wag1 gene and there is no tail formation.
3) ntrdr gene - stimulates the activity of brkn gene thus this in turn inhibits Wag-1 gene and results in inhibiting the tail formation.
(2) The ntrdr gene stimulates the brkn gene and active brkn gene inhibits the wag-1 gene. As we know Wag1 gene is essential for tail formation. on removing out ntrdr gene result in inactive gene brkn thus allows the expression of the Wag-1 gene allowing tail growth in dogs.
His experiment with his swan. Expedia flask disproved spontaneous generation in that broth was left open to air yet no life grew in the broth, the neck design of the flash trapped all possible contaminates. This broth today is still sterile despite sitting in a museum for decades.
The answer is Maria is having an emotion-focused coping. Emotion-focused
methods can support with nearly all stressors. These approaches construct
emotional flexibility to stressors now and in the future. Emotion-focused
coping is well well-matched for stressors that seem uncontainable (ex. a
terminal illness diagnosis, or the loss of a loved one).
The marine industries affected the marine life and ocean water in many ways. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH drops. In the past two hundred years alone, ocean water has become 30 percent more acidic and faster than any known change in ocean chemistry in the last million years.
