You have been hired to forecast future population level for a small country. You know that this country currently has 25 million citizens and wishes to achieve a population level three times the current population, 25 years from now. (a) What population growth rate must it maintain in order to achieve this goal

Explanation below

Explanation:

It should be understood that the population growth rate of a particular country can be explained or described as the increase in the number of the citizens of that country.

There are so many factors that contribute to an increase in the number of people of a country. These include influx of people into the country, increase in birth rate and decrease in death or mortality rate.

In this case, the growth rate is usually calculated in percentage, so the growth rate should be around 3.5%.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
