Ur answer is C,,,, Population
Answer:
Explanation:
Bicoid gene is the maternal effect gene whose protein concentration gradient patters the anterior-posterior axis in Drosophila embryogenesis. It was the primary protein that is demonstrated to act as a morphogen. Morphogens are proteins whose concentration gradient will affect the developmental fate of the surrounding region.
The specified bicoid gene is the one which codes for bicoid protein. This protein is being existing in a gradient manner in the egg and thus its concentration is higher at the anterior end and lower in posterior end.
This bicoid protein is responsible for the stimulation of the development of the anterior end.
The posterior region (including the hindgut) expands and extends towards the anterior pole along the dorsal side of the embryo. At this time, segments of the embryo become visible, creating a striped arrangement along the anterior-posterior axis.
<span>a serious mutation in ribosomal RNA gene is worse. the mutated ribosomes may lose their abilty to bind to messenger RNAs through Shine Dalgarno Sequences. they may also present wrongly placed E,P and A sites to the messenger RNA. this will lead to lethal results ranging from abnormal polypeptide formation to no formation at all.</span>
Answer:
<em> </em><em>Pseudomonas aeruginosa, Serratia marsescens, Klebsiella pneumoniae or Escherichia coli </em>
Explanation:
Meningitis is the inflamation of the meninges (membranes that cover the brain and spinal cord) due to the infection of the fluid around it. Some of the symptoms are fever, sleepiness, nausea and vomiting, stiff nech and seizures.
Meningitis can be caused by Gram negative bacterie such as<em> H. influenzae., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa or Serratia marsescens</em>. <em>From these options only </em><u><em>Pseudomonas aeruginosa, Serratia marsescens, Klebsiella pneumoniae </em></u><em>and </em><u><em>Escherichia coli </em></u><em>are rod-shaped gram negatives.</em>
