In chapter sixteen, Tayo's uncle, Kayode, revealed to him that he was considering studying engineering at the Insitute du Petrole in France

Clothings, gloves, cardigans and extra socks are outfits worn during winter when the temperature is low, cold

In chapter Nine, Tayo was showing Vanessa his collection of photographs when Christines popped out and then he lied about her being his cousin.

Chapter Twenty-one (21) of the book gave a narrative about how Tayo had been writing about the problems of Nigeria and how he believed that greed and mismanagement were the root causes of the problems.

Gametes are reproductive cells (sex cells) that unite during sexual reproduction to form a new cell called a zygote. Male gametes are sperm and female gametes are ova (eggs). Embryo is the stage of animal development in the uterus before the animal is considered a fetus. In humans this is equivalent to the first three months.

Savannas are quite low in tree species diversity because of stringent ecological requirements but fairly high in diversity of herbaceous plants. Tree growth is controlled not only by rainfall but also by soil type; large areas of hardpan soils, allow no tree roots to penetrate except through cracks, and the cracks determine tree distribution. Large mammals are at their most diverse in this open environment, in which they can move about freely and yet find shelter among woody vegetation. Large herbivores are successful because of the tremendous biomass of herbaceous vegetation produced annually, and there are many carnivores to crop them in turn. Tropical rain forests occur in areas of tropical rainforest climate in which there is no dry season, distinct buttress roots of trees. Montane forest refers to any ecosystem found in mountains. These ecosystems are strongly affected by climate, which gets colder as elevation increases. A desert is a barren area of landscape where little precipitation occurs and consequently living conditions are hostile for plant and animal life.

Red blood cell aslo kn own as erythrocytea disk-shaped, biconcave cell in the blood that contains hemoglobin, lacks a nucleus, and transports oxygen and carbon dioxide to and from the tissues White blood cells or leukocytes, are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Platelets, or thrombocytes or yellow blood cells, are very small, irregularly shaped clear cell fragments (i.e. cells that do not have a nucleus containing DNA. Platelets are a natural source of growth factors. They circulate in the blood of mammals and are involved in hemostasis, leading to the formation of blood clots. Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells

The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the body’s weight. Movements at the knee joint are essential to many everyday activities, including walking, running, sitting and standing. The knee, also known as the hinge joint(tibiofemoral joint) formed between three bones: the femur, tibia, and patella. A gliding joint, also known as a plane joint or planar joint, is a common type ofjoint formed between bones that meet at flat or nearly flat articular surfaces. Pivot joint, also called rotary joint is a freely moveable joint that allows only rotary movement around a single axis. Pivot joints also provide for the twisting movement of the bones of the forearm (radius and ulna) against the upper arm. The ball and socket joint (or spheroidal joint) is a type of synovial joint which enables the bone to move in many places (nearly all directions). These are found in the hip.

Most enzymes do not function optimally, or even at all, unless bound to other non-protein helper molecules called cofactors.

Morphological variation includes aspects of the outward appearance i.e shape, structure, color, pattern, size which is in contrast to physiology variation which deals primarily with function. Morphological variation arises from a number of factors which can be bluntly classified as either genetic or environmental implanted into the process of evolution.

The spirogyra and volvox are cells. The spirogyra is a cell acting as a FILAMENT while in the Volvox, it's a cell as a COLONY.

Cohesion is an ability of water molecule to stick to one another due to the presence of hydrogen bonding

Nucleus is a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. This membrane seems to be continuous with the endoplasmic reticulum (a membranous network) of the cell and has pores, which probably permit the entrance of large molecules. The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Adaptation is process by which an animal or plant species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation. Even the simpler organisms must be adapted in a great variety of ways: in their structure, physiology, and genetics, in their locomotion or dispersal, in their means of defense and attack, in their reproduction and development, and in other respects. Evolution explains how living things change over a long time, and how they have come to be the way they are Variation is any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability. Succession is the process by which the structure of a biological community evolves over time. Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Secondary succession occurs in areas where a community that previously existed has been removed; it is typified by smaller-scale disturbances that do not eliminate all life and nutrients from the environment.
