Understanding evolution helps us solve biological problems that impact our lives. There are excellent examples of this in the field of medicine. To stay one step ahead of pathogenic diseases, researchers must understand the evolutionary patterns of disease-causing organisms. To control hereditary diseases in people, researchers study the evolutionary histories of the disease-causing genes. In these ways, a knowledge of evolution can improve the quality of human life.




Answer:
D. Warm front
Explanation:
Warm fronts typically have warmer and more moist air than the air in front of it. Replacing the cold air with warm air can cause precipitation.
Answer: D. Genetic mutation
Explanation:
For evolution to occur, there must be a genetic mutation in the genome of an organism such that a new allele is formed.
If this mutation occurred in the sperm and/or the ovum, the mutation will then be passed on through reproduction to the next generation. This leads to more of the subsequent generations having that mutation thereby leading to evolution.
In homo sapiens the first word refers to which taxonomical grouping Genus.
Taxonomy is the science for the naming, describing and also classifying the organisms that includes all plants, animals and the microorganisms of the world.
Today is the 290th anniversary of the birth of the Carolus Linnaeus, the Swedish botanical taxonomist who was first person to formulate and the adhere to a uniform system for the defining and naming the world's plants and the animals.
The purpose of the taxonomy is to categorize the organisms based on their common characteristics and for the descent. The main aim of taxonomy is to identify, the characterise, classify and to give the specific names to all of the living organisms according to their main characteristics

Answer;
-Matrix
Explanation;
Matrix is used to maintain artificial wall around the tooth preparation.
Cavity preparation is the mechanical alteration of a tooth to receive a restorative material which will return the tooth and area to proper form, function and esthetics.
-Objectives of cavity Preparation: remove all defects and give the necessary protection to the pulp, locate the margins of the restoration as conservatively, form the cavity so that under the forces of mastication the tooth or the restoration will not be displaced and also Allow for the esthetic and functional placement of a restorative material.
