The four issues in psychology that the authors have tried to explore through the perspective of evolutionary psychology and evolutionary developmental biology are whether the mind is domain-specific or domain-general, influence of nature and nurture on human mind, whether development takes place in stages or gradually, and how the individual differences arise. Authors feel that as mainstream evolutionary psychology do not accept the ideas and tenets from evolutionary biology, its tenets have been proven wrong by empirical studies. Certain tenets like, 1) complex biological and psychological mechanisms exist due...

These aspects are effectively captured by the other theories which incorporate “desire” as a component.

Biology for General Ed

...Biology for General Education Introduction Biology is basically the study of life. (Carter, 2004) Since living things around us exists in the form of plants, animals, or insects; the study of biology branched out to other related subject such as: botany, zoology, and entomology. As a biologist, being a good observer is one of the most important characteristic necessary in the study of Biology. Aiming to test the researcher’s ability to perform a keen observation, the researcher will visit a garden which is located near the area where she lives. In the process, the researcher will discuss every single living thing that can be found in the garden and eventually develop a hypothesis based from the researcher’s visual observation... . To...

The heart rate should be minimum at resting time and maximum after exercise. To perform various activities the body needs energy accordingly. Heart rate will increase when the energy requirement of the body increase and vice versa. However, there is maximum and minimum limits of heart rates for healthy heart and body metabolism functioning. To test the hypothesis following data was recorded. 1b.

Biology - DB 1

...Biology - DB Part A cell being the fundamental unit of life can be differentiated into eukaryotic and prokaryotic cells. The structure and functionality of a cell are made possible by the basic characteristics that form the components of the cell. Eukaryotic cell function at their best through an interplay of action of the organelles that control the functionality of the cell. Nevertheless, despite the absence of the organelles in the prokaryotic cells, the cells are adapted to their functionality at their best. In this regard, a cell can be compared to an organizational set-up equipped with tools and appliances that enables smooth operation and achievement of the objectives of the organization (Kietrys, Szopa, &...
