The resulting social bonds from these relationships facilitate other needs as well. These include the need for a sense of belonging, the desire to love and be loved and the desire for sexual fulfillment. From the satisfaction of these needs, man derives a sense of completeness and in the process, his survival is ensured. Human beings are different form each other and consequently, are unique in their tastes and preferences for a suitable mate. This is especially true of the…...
Respiratory System of a fish
Words • 1325

The respiratory system is an intricate structure existing in most forms of life, which allows for these organisms to take air into their bodies for cellular respiration to take place inside cells, as the name suggests. Cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. In humans, glucose is the 'fuel' molecule, which is oxidised by oxygen, producing carbon dioxide, water and energy. The formula is this: C6H12O6 (aq) + 6O2 (g)…...

The nose is the primary passageway for air entering the respiratory system. Air normally enters through the paired external nares, or nostrils, which open into the nasal cavity . The vestibule is the space contained within the flexible tissues of the nose The nasal septum divides the nasal cavity into left and right portions. The superior , middle , and inferior nasal conchae project toward the nasal septum from the lateral walls of the nasal cavity. A bony hard palate…...

The human skeleton consists of 206 bones, many of which move or hinge at joints and which, enable the body to achieve a variety of actions, such as running, throwing, striking, pulling and pushing. The human skeleton was created by evolution to perform six functions: I. To provide a lever system against which muscles can pull II. To provide a large surface area for the attachment of muscles III. To protect delicate organs (i.e the cranium protects the brain) IV.…...

Evolutionary Explanations Of Aggression Psychology
Words • 498
Pages • 2
The concept of evolution is undoubtedly a scientific one, combining many areas of science in the explanation of the success of all species. From an evolutionary approach, aggression is primarily considered to be an adaptive behaviour driven by internal, biological factors. These factors may be related to concepts such as Darwin’s survival of the fittest, where aggression is an innate trait that is deemed critically necessary. In this regard, there are links to the biological approach which also places strong…...
Discuss the relationship between sexual selection and human reproductive behaviour
Words • 725
Pages • 3
According to evolutionary psychologists, sexual selection is the choice of characteristics to increase reproductive success. There are two forms of sexual selection; these are inter-sexual selection and intra sexual selection. Inter-sexual selection, also known as ‘mate choice’ is a behaviour seen between sexes to ensure reproductive success. In inter-sexual selection a mate is chosen due to the individual possessing a desired characteristic for reproduction, e.g. a male may pick a female partner with wide hips due to wide hips being…...

A complete introduction to the cellular world Cells There are many parts of a cell, they all have specific duties, and are all needed to continue the life of the cell. Some cells exist as single-celled organisms that perform all of the organism's metabolism within a single cell. Such single-celled organisms are called unicellular. Other organisms are made up of many cells, with their cells specialized to perform distinct metabolic functions. One cell within an organism may be adapted for…...

Introduction Humans are primates; however, we are not the only primates on Earth. According to Trzepacz, Timmons, and Duobinis-Gray, "Primate classification includes animals such as the tiny tarsier, the acrobatic lemur, the flamboyant mandrill, and the powerful gorilla." (12-2) What makes us primates is the certain characteristics we share; the main characteristic being our ability to grasp objects using our hands. Humans are further classified as hominids.

Penile length is measured using a straight edge on the dorsal surface in the non-erect state from the pubic ramus to the tip of the glans while compressing the suprapubic fat pad and applying gentle traction. Mean stretched penile length is approximately 3.75 cm (± 0.54 cm) at one year of age and gradually increases to 4.84 cm by late childhood, then increases sharply to about 9.5 cm (± 1.12 cm) by late puberty (Tomova et al., 2010).

Abstract Many ethnologists have been investigating how do different human disturbances affect the behavior of ungulates. So my group and I also studied or carried out an investigation on how varying levels of human disturbances affect the behavior of ungulates. Based on how we viewed the structure of the specific ungulates, we predicted that different human disturbances do not have an effect on the behavior of the ungulates. We carried out our in Golden Gate National Park, using binoculars and…...

Studies in the field of behavioral and reproductive biology have proved that courtship is of great importance in the population of guppy (Poecilia reticulate). In this courtship male guppies are known to attract females by displaying their body. Females are known to attract to males with large body contour, much colorful fins and with greater courtship display. In the time of courtship, male guppy expands its fins and repeatedly moves its body from back of head to tail end in…...

In the 1940s, Ernst Mayr created the term Biological Types Idea that was subsequently extensively welcomed by the scientific community. The definition mentioned that "Species are groups of in fact or potentially interbreeding natural populations that are reproductively separated from other such groups". Specific mechanisms remain in place to avoid species from interbreeding with others and these are described as reproductive separating systems, which are biological incompatibilities. There are many mechanisms acting on natural populations and these are broadly grouped…...

An essay on the mechanism of breathing and its control The basic mechanisms involved in inspiration and expiration are as follows; Inspiration The contraction of the diaphragm and external intercostals muscles leading to an expansion of the lungs. This expansion means there is an increase in the volume of the thorax and a decrease in intrapulmonary pressure. A pressure gradient is therefore established from the atmosphere to alveoli, hence air being suck into the lower pressure in the lungs called…...
