If you were planting a vegetable garden, what should you consider for the time of planting?
zvonat [6]

When planting vegetables it is very important to know the climate of the area, its usual patterns, and how will that affect the growth and development of the crops. The soil quality too is very important, as it is the basis for the development of the root-stock of the crops.

If we have a temperate type of climate, than we have four different seasons, meaning different weather patterns throughout the year. We can take onions, radish, and peppers as vegetables of choice. The onions can be planted in mid-autumn, as they will need more moisture, and they are resilient to low temperatures, thus will not have problems in the winter, and in the spring they will already have the basis so will grow quickly and be larger. The radish can be planet in late winter or early spring, in a period when there is more precipitation. It is not a vegetable that likes high temperatures, so with its quick development, it will be able to develop the tuber by late spring. The peppers can not sustain low temperatures, so they should be planted in late spring. They also like warm weather and lot of water, so it will be needed to water them a lot in the hot and dry period. They will manage to develop and produce the vegetables by the end of the summer, thus not getting damaged by the cold nights in the autumn.

3. The time between the end of ventricular systole to the beginning of atrial systole.
amid [387]

Answer:

The time between the end of ventricular systole to the beginning of atrial systole is 100 ms or 0.1 seconds.

Ventricular systole is the removal of blood from the heart by pumping through aorta and pulmonary vein. Both aorta and pulmonary vein receive the blood from the heart. Aorta receives oxygenated blood and pulmonary vein receive deoxygenated blood, while atrial systole is the addition of blood into the ventricular from vena cava and pulmonary artery due to contraction of heart. This process occurs in 100 ms.
