You find that the polarity of microtubules in the alternate universe cilia is the opposite of the polarity of the microtubules in cilia from your body. Describe the arrangement of the microtubules of these alternate universe cilia. Also, describe possible steps for the process of intraflagellar transport in these alternate universe cilia.

Please describe in cancer research what the limitations of sequencing whole genomes are. What is the goal of sequencing and the challenge of sequencing? What tools can be used to increase the effectiveness of sequencing? Do you agree/disagree with the following statement and why: It will be discovered that cancer is a disease that is caused by disruptions in a small number of molecular pathways?

Identify one aspect of translation that is present in Bacteria but absent in Eukarya: Group of answer choices :
rRNA in the large subunit of the ribosome plays a catalytic role
The elongation stage is sensitive to the presence of diphtheria toxin
The genetic code consists of 64 unique 3-nucleotide codons
A peptide bond forms between the amino acid of one amino-acylated tRNA and a peptide on the other tRNA
An tRNA carrying methionine is recruited to the ribosome to form the initiation complex
The small subunit rRNA molecule anneals to the Shine-Dalgarno sequence on the mRNA

(a) Give a brief overview of the theory of evolution, and explain why it is the principle of unifying concept in biology. The length of the overview should be less than 500 words. (b) Apply the theory of natural selection to any given adaptation, and suggest a logical explanation of how the adaptation may have evolved.

condition swyer syndrome .
Compare the development of the individual with the condition you chose in question #1 with the development of an individual of the same sex chromosome set, but without any of the mutations that caused the condition

A mountain climber ascends to an altitude where the partial pressure of oxygen in the atmosphere is very low.
a. What happens to the climber’s ventilation rate?
b. Which chemoreceptor (oxygen or carbon dioxide/pH) would cause this change in ventilation rate at high altitude? Your answer should reflect that you know the stimuli for change in ventilation rate under different conditions
c. What happens to plasma concentrations of carbon dioxide after a period of time hyperventilation?
d. What happens to plasma pH after a period of time at high altitude? Your answer should reflect that you understand the relationship between CO2 levels and pH.
e. What happens to levels of erythropoietin in the blood after a period of time at high elevations? Your answer should include the stimulus for the release of EPO
f. How does a low concentration of oxygen in the alveoli affect the state of contraction of pulmonary arterioles?
g. Explain why pulmonary edema is a symptom of altitude sickness. Your answer should demonstrate your understanding of fluid exchanges at the capillary level
