Which plants are usually the first to grow during secondary succession

2 answers:

5 0

I'd go with weeds. While trees could be in the secondary succession, it is more likely than not that small plants and such would be easier to grow first. Upon the Primary succession, lichen, ferns, weeds and other small plants like that sprout, and eventually evolve into trees and other large plants as the nutrient content of the soil increases. You can do more research on this if you doubt my answer or email me for more information. Hope this helps.

You have just delivered a premature baby. Your assessment reveals that he is breathing adequately; however, his heart rate is 90

Answer:

The answer is letter B, keep him warm and ventilate with BVM.

Explanation:

In order to know more about the answer, let's check out the meaning of "Premature Baby" first.

Premature Baby- a baby born through premature birth (fewer than 37 weeks). Babies are normally born at the usual 40 weeks. Health problems may occur with premature babies, thus it is very important to monitor them.

In the situation above, the premature baby's heart rate is only 90 beats/min. A resting heart rate for a newborn infant is 130-150 beats per minute. This means that the baby above has a slow heart rate. In order to increase the hear rate, it is important to keep the baby warm and to ventilate with a "Bag Valve Mask" (BVM). An increase in internal temperature increases the heart rate. Increasing ventilation will also help increase the heart rate.

Remember: Inhalation increases the heart rate.
