Muscle Tissue 1. How is muscle tissue categorized? Muscle tissue is categorized by its shape‚ the number of nuclei‚ and the mechanism of stimulation. 2. a. Click the Smooth Muscle Tissue. Identify each of the following: Nucleus----- Smooth Fiber Muscle------------------ b. Describe smooth muscle control (voluntary or involuntary). Involuntary c. Name some smooth muscle functions (click the “Tissue Locations” button). Smooth

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

body. Introduction Respiration is the physical process by which living organisms take in oxygen from the surrounding medium and emit carbon dioxide. The term respiration is also used to refer to the liberation of energy‚ within the cell‚ from fuel molecules such as carbohydrates and fats. Carbon dioxide and water are the products of this process‚ which is sometimes called cellular respiration to distinguish it from the physical process of breathing. Cellular respiration is similar in most organisms

somewhat different between cancer and non-cancer cells. Normal cells will generally use pyruvate for aerobic respiration in the Tricarboxylic Acid (TCA) cycle and oxidative phosphorylation if oxygen (O2) is present. In the absence of O2‚ these cells will undergo anaerobic respiration and convert pyruvate into lactic acid. Cancer cells‚ on the other hand‚ will push pyruvate through the anaerobic pathway regardless of O21‚ 2. While this metabolic pathway yields less energy than the TCA cycle and oxidative

Larger muscles would have more‚ and smaller muscles would have fewer AEROBIC RESPIRATION-Cells only store a small amount of ATP molecules‚ so the chemical process of cellular respiration is necessary to convert energy from our food into enough energy for ongoing muscle contraction and other cellular work. The organic molecules in food contain stored energy

4) Section 33 Yeast Cell Respiration 10/04/2010 Part B: Explanation of Results All cells carry out the process of cell respiration in order to meet their energy needs. It is advantageous for cells to have the ability to metabolize different substrates. In this experiment‚ we investigated each sugar’s (glucose‚ lactose‚ sucrose‚ fructose‚ and lactose/lactaid) cell respiration rate. When referring to my group’s graph and data‚ glucose ended up with the highest respiration rate (1‚177.2 ppm/min)

Seven characteristics of life In life‚ there are seven different characteristics these being; movement‚ excretion‚ respiration‚ reproduction‚ irritability‚ nutrition and growth. Below‚ I will explain each of the characteristics in detail. Reproduction means; “the production of offspring by a sexual or asexual process” (oxford concise colour medical dictionary‚ 2007). Animals and plants do this in different ways‚ animals need two parents‚ and therefore the offspring will share both of the parent’s
