Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.
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.

Answer:
The correct answer is - Basophils
Explanation:
Basophils are one of the granulocytes of WBC. The basophils move to site of damaged tissue. They cross the capillary endothelium and gathred in the damaged tissues. They discharge their granules into the interstitial fluids.
The granules which is secreted by basophils includes histamine, heparin, and serotonin.The histamine dilates blood vessels, the heparin prevents blood clotting.
These chemicals into the interstitial fluids enhances the inflammation initiated by mast cells.
