Biology Of The Boxelder Bug In Cache Valley, Arab Bakir Al-Tikrity May 1952

Biology Of The Boxelder Bug In Cache Valley, Arab Bakir Al-Tikrity

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The boxelder bug, Leptocoria trivittatue (say), is a hanipterous insect belonging to the family corisidae. Although it rarely is a pest of agricultural crops, its habit of invading homes and other buildings for hibernation and to warm itself has made it an annoying household pest. It has proven to be a difficult insect to control. Only a few of the contact insecticides, useful in control of related insect pests, have given satisfactory control of the Boxelder Bug. Because it has not been considered a critical problem, it has not received detailed attention from the scientific investigators. Its close association with …

A Curriculum Study Of The Biological Science Courses In The Secondary Schools And College Of Utah During 1947-48, Merrill H. Gunnell May 1948

A Curriculum Study Of The Biological Science Courses In The Secondary Schools And College Of Utah During 1947-48, Merrill H. Gunnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

At the present time there is a feeling among biologists in Utah that there should be improvement in biological science courses and course sequence to better fill the needs of the non technical student. There are many students filling group requirements with an accumulation of courses which may not provide them with the more important fundamental concepts and principles in biology. Information concerning these courses in high schools and colleges in necessary to provide a basis for curriculum revision in the field. Such information should be useful in evaluating the present system and suggesting modifications. Because of the need for …

An Analytic Comparative Study Of Certain Biology Textbooks Used At Secondary School Level, Joseph E. Rankin Jul 1947

An Analytic Comparative Study Of Certain Biology Textbooks Used At Secondary School Level, Joseph E. Rankin

Master's Theses or Doctor of Nursing Practice

Biology is the science of life and therefore deserves every consideration in the high school curriculum. The world today is making an extensive and intelligent use of biology in solving problems of personal and social significance. Scientists have discovered that certain phases of the subject are more important to man's welfare than others. For this reason it is essential that biology be presented to our high school students not as isolated facts, but in relation to the problem of living. Through this science of living things, the student can gain a healthy respect for facts and for conclusions based on …

Organization And Polarity Of Protoplasm, John P. Munson Jan 1910

Organization And Polarity Of Protoplasm, John P. Munson

All Faculty Scholarship for the College of the Sciences

In higher forms of life, we usually concede the presence of an organ specialized for the performance of a function. In these higher forms coordination of organs, which entails a regular sequence in their functions, is readily made out; and it seems a mere platitude to say, of these, that organization determines the functions of the organism. To what extent can functions exist in the absence of organization; does the one precede the other; or have function and organization developed simultaneously, out of matter devoid of both structure and function? In my studies on the cell, I have kept these …

Embryology And Evolution, Malo Marius Amunson Jun 1906

Embryology And Evolution, Malo Marius Amunson

Manuscript Thesis Collection

The proofs of evolution must be sought in the entire field of science. Direct proof is found in the study of Morphology, whose bases are comparative anatomy; embryology; in the study of paleontology, of geology, of geographical distribution, in the study of nature and experiments of today. In this vast field of direct proofs of evolution it is our purpose to present some of the evidences of evolution as furnished by one of these, namely, Comparative Embryology.

Spermatogenesis Of The Butterfly, Papilio Rutulus, John P. Munson Jan 1906

Spermatogenesis Of The Butterfly, Papilio Rutulus, John P. Munson

All Faculty Scholarship for the College of the Sciences

For a number of years I have been studying the spermatogenesis of Papilio rutulus (pl. 12, fig. 1) not ,with any one single problem especially in view, but with the aim of ascertaining the entire life history of its sperm cell, its various phases of development, its mode of growth and differentiation, the history of its several parts, and its relation to the organism.
