<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>

Which statement presents a commonly-found format for hypotheses?
swat32

Answer: a) If the independent variable is changed, then the dependent variable will also change.

Explanation:

A hypothesis is the assumed explanation for the cause of the natural process. This can be testified on the basis of the experimental process, which will involve the cause and effect relationship between the independent and dependent variables.

The independent variable can be changed in an experiment manually. The impact of such change can be observed on the dependent variable to test the hypothesis.

State where bile is synthesized and explain the role of bile in digestion and excretion
earnstyle [38]
Liver secretes bile which is then stored in gall bladder. Bile enters the duodenum via the bile duct. Bile emulsifies lipids, transforming large lumps of lipids into tiny droplets, which provide a larger surface area for digestion. This allow lipid digestion to proceed more rapidly. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine.Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.
