Answer:
A. a developing nation
Explanation:
Age pyramids are the age structure diagrams that represent the number and proportion of people at each age in a population. The base of the age pyramids represents the population in pre-reproductive age which is from 0 to 10 years. The overall shape of an age pyramid indicates if the population is increasing, stationary, or shrinking.
The age structure diagram for a developing nation has a broad base that tapers quickly towards the top. This means that a larger percentage of the population is in the pre-reproductive age group and reproductive age group with a smaller percentage of the population in the post-reproductive age. These countries have a great chance of future population growth.
Answer: option D.
Phenotype
Explanation:
Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.
Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.
Answer:
DNA polymerase makes a molecule of RNA from a DNA template
Explanation:
DNA polymerase is an enzyme involved in the process of DNA replication. DNA replication replicates or synthesizes a new DNA replicate from the parental DNA.
The enzymes mentioned in the question perform a specified function which is matched with their description except for DNA polymerase as this enzyme is responsible for adding nucleotides to the synthesizing strand from the template strand f DNA.
Thus, the selected option is correct.
D. Lateral
Explanation:
Lateral faults are not one of the three principal types of faults. A fault is a geologic structure produced as a result of brittle deformation of a rock. It results in blocks of rocks moving relatively one another.
There are three types of faults in a rock:
- Normal fault
- Thrust fault
- Strike slip fault
Normal and reverse faults can also be referred to as dip-slip fault.
- In a strike slip fault, two rocks slide past one another.
- This is different from dip slip faults in which a block slides down or up of another.
