What are some of the concerns associated with our increasing population and consumption of resources?
Ugo [173]

Explanation:

As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.

  • Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
  • Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
  • Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
  • High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

olasank [31]

A) <u>Mutation</u> is the original source of variations for plants and other organisms  which develops differences among their respective species

Explanation:

Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.  

A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.  

Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.

<h3>Nervous system :</h3>

According to the classical doctrine of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals to and from various regions of its body.

<h3>Somatic nervous system :</h3>

The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system responsible for the voluntary control of skeletal muscle movement.

A part of the peripheral nervous system called the somatic nervous system is responsible for the voluntary control of skeletal muscle movement.

<h3>Example somatic nervous system</h3>

The cranial nerves, which transmit information from the brain to the head and neck region, are an illustration of the somatic nervous system. In this area, conscious motor functions are under the control of the somatic nervous system.
