Unit 1. Homeostasis and Integument 1. Define what is meant by homeostasis in living systems a. Homeostasis = Body wisdom ↓ ↓ Steady state * Homeostasis keeps us healthy * The means by which organisms (our body) maintain a constant internal environment in spite of fluctuations in the external environment. * This means humans have narrow limits we have to keep. 1. Body temp 2. Water content * Our blood contains 92% water and has to maintain

The poem ‘Valentine’ by Carol Ann Duffy portrays a realistic and honest view on love. Duffy has a unique perspective of love contrasting to the stereotypical way love is often thought about. She compares love to an onion‚ which is odd because an onion is neither visually appealing nor valued but Duffy’s insight on love and unconventional way of perceiving love is what makes the poem Valentine interesting. She presents her ideas by using a range of different poetic devices such as‚ choosing a distinct

Parts Observations 1 Evaporation Both the water and alcohol felt cool on the wrist. The water felt cooler at first‚ then the alcohol started evaporating faster and it felt cooler. The alcohol drew heat from the body as it’s evaporating thus creating a greater heat loss and temperature change. 3 Skin Prints Different areas of the skin have different skin prints. A fingerprint has a loop design‚ whereas the skin print of a palm is straight and linear. The lines of a wrist print are interconnected

The purpose of this lab is to determine whether salt affects the movement of water in the cell. Independent variable is the factor that affects the value of variables dependent to it. In osmosis lab‚ the independent variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled variables are

meiosis on cell specimens. It involves the modelling of the stages of meiosis and also the staining procedures to identify mitosis in onion root tip. There are two parts to the procedure of the experiment whereby the first is staining and observing mitosis in onion root tips and the second being observing and comparing mitosis between whitefish blastula and onion root tip. The results are that the five stages of mitosis have been observed and sketched‚ together with a comparison of telophase in plant

the body and its cells are continuously replaced as they are lost to normal wear and tear. The skin has between 12 to 20 square feet in area and accounts for 12% of body weight. It is composed of 3 layers the epidermis‚ the dermis‚ and the sub cutis. The thickness of the epidermis and the dermis varies over different parts of the body. It is thicker on the palms of our hands and feet‚ and thinner on our eyelids which have to be light or our eyes would always be closed. The dermis‚ or known

Integument: The four layers of the epidermis from the deepest layer to the most superficial layer is stratum basale‚ stratum spinosum‚ stratus granulosum‚ stratum corneum. Even though the sebacious glands and sudoriferous glands have ducts that open onto the skin surface or a hair follicle‚ the actual glands are located in the dermis. The epidermis is composed of a keratinized stratified squamous epithelium. Just like other epithelia‚ it is

Adenosine Triphosphate Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell‚ and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP. (Guyton) As food in the cells is gradually oxidized‚ the released energy is used to re-form the ATP so
