The youngest would be the ones at the top and the oldest would be at the bottom. the oldest is B and the ones around it, as they get bigger get younger. hope this helps :)
The calcium present in the milk acts as a fertilizer, for the growth of pumpkin size.
Explanation:
Scientific answer: Milk contains nutrients, minerals mainly calcium which are good for the growth of the plant as a fertilizer.
Milk gets readily absorbed by the roots due to the solubility of nutrients in milk.
The root hairs of the plant transport the calcium to the other parts like stem.
This will only help when all other factors of plant growth are present as sunlight, water other than fertilizer.
Non-scientific question:
The Hypothesis here is those pumpkin plant fed with milk are bigger on size.
Also injecting stems with milk would cause no good.
Pumpkin plants fed with milk and some plants fed with water are compared, we get the result that giant pumpkins are one that are fed with milk. This is statistical analysis.
You don't have an answer choice.
Answer:
The answer is (A. A cladogram.)
Definition: "The type of circulation pathway in which venous blood is passed
<span>from the right atrium of the heart through the right ventricle and
</span> pulmonary<span> arteries to the lungs where it is oxygenated and its return via the </span>pulmonary<span> veins to enter the left auricle and participate in the systemic </span>circulation"<span>.
Explanation:
There are two circulatory path in cardiovascular system namely pulmonary circulation and systemic circulation. Pulmonary circulation path allows for blood circulation through lungs for oxygenation while systemic circulation allows for transport of oxygenated blood to all parts of the body.
Pulmonary Circulation Pathway: Pulmonary circulation pathway consist of:
1. Superior and inferior vena cava:
De-oxygenated blood from lower parts of the body enter to right atrium through inferior vena cava. Similary, deoxygenated blood from upper parts of the body enter to right atrium through superior vena cava.
2. Right atrium and right ventricle:
From right atrium the blood passes to right ventricle through tricuspid valve.

3. Pulmonary artery: Afterwards, the blood enters the pulmonary artery via the pulmonary valve. The pulmonary artery divides into two arteries with one artery entering the right lung and the other artery entering the left lung. When the blood reaches the lungs through the left and right pulmonary arteries, it moves over alveoli via the capillary beds. </span><span>
</span><span>
4. Left atrium and left ventricle: After the blood gets oxygenated, it moves back to the heart and this time moves into the left atrium, completing the pulmonary circulation path.</span><span>
