What happens to the total population when the birth rate is at 40 and the death rate is at 15?
Trava [24]

If the birth rate in a population is 40, and the death rate in that population is 15, then the population will be experiencing growth. The growth will be 25 on every 1,000 people. If this trend continues for longer period, then the population will start to become younger and younger, making the basis of the population pyramid wider, while the top part of it smaller and smaller. This demographic situation in modern times seems to be present only in the less developed countries, with the majority of the transitioning countries having much decreased population growth, and the more developed countries having more deaths than births, thus being aging populations.

Which of the following substances would NOT transport readily in blood?
Levart [38]

The substance that would not transport readily in blood is : Triglycerides ( B )

<u>Although your question lacks some data below are the missing options</u>

  1. Fibrinogen
  2. Triglycerides
  3. Monosaccharides
  4. Albumin
  5. Carbohydrates

Triglycerides are not readily transported in blood but it is contained in dietary fat which is been absorbed by the body through the intestine in the form of chylomicrons ( triglyceride-rich lipoproteins ).

When the chylomicrons gets to the liver, the liver disassociates the Triglycerides from the chylomicrons that is needed by the body for energy.  

Hence we conclude that the substance that would not transport readily in blood is Triglycerides.
