Give me a summary on population growth

Two types of population growth patterns may occur depending on specific environmental conditions:

An exponential growth pattern (J curve) occurs in an ideal, unlimited environment.

A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth. Two types of population growth patterns may occur depending on specific environmental conditions. Population growth is the increase in the number of individuals in a population. Global human population growth amounts to around 83 million annually, or 1.1% per year.Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.

Explanation:

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.

explanation:

this transfer is call conjunction
