The rules that govern phonology describe the sound sequences that can occur in a language. Phonology is the science of speech sounds that constitute the fundamental components of a language. It is also the study of sound relationships within a language or between languages in the world.
Answer:
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Explanation:
Below are the null and alternative hypothesis,
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Test statistic for text of significance
z = (pcap –p)/ ![\sqrt{ [p*(1-p)/n]}](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Bp%2A%281-p%29%2Fn%5D%7D)
z = (0.576 – 0.65)/ ![\sqrt{[0.65×1-0.65)/125]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B0.65%C3%971-0.65%29%2F125%5D%7D)
z = 1.73
P- value Approach
p-value = 0.0414
As P-value < 0.05, we reject the null hypothesis
There is sufficient evidence to conclude that the mother consumed vitamin D supplements during pregnancy. A researcher in a northern region felt that the percentage should be lower for this region because with reduced hours of sunshine during winter months, pregnant women tended to use of higher doses of supplements to compensate.
Microtubules are long,hollow protein cylinder that form a rigid skeleton for the cell golgi apparatus

Take two healthy potted plants. Keep them in a dark room for 2-3 days. Now place each plant in a separate glass. Get a cup containing potassium hydroxide by the side of the plants (the potassium hydroxide is used to absorb carbon dioxide). COver both plants with separate jars. Seal the jars so that the set-up-is-air-tight. Keep the plants in sunlight for two hours. Gently pluck a leaf from each plant. remove the chlorophyll from the leaves by boiling them in alcohol. Wash the leaves with water and then pour iodine solution over them.
We can conclude that the photosynthesis cannot be carried out without carbon dioxide. the leaf from the plant (which was the jar containing potassium hydroxide, which absorbed the carbon dioxide) turns blue black on iodine solution showing that starch is presented in this lead.
so this shows that carbon dioxide is necessary for the processs of photosynthesis to take place
