The skeletal system serves several important functions in the body. Firstly, it provides structural support, giving shape and form to the body and supporting the organs. Secondly, it facilitates movement by serving as attachment points for muscles and allowing for joint mobility. Additionally, the skeletal syst...

Pre-Lab Questions 1. How do banding patterns change when a muscle contracts? When a muscle contracts, the banding patterns within the muscle change due to the sliding filament theory of muscle contraction. This theory suggests that muscle contraction occurs when thin filaments (actin) slide over thick filaments (myosin), resulting in the overlapping of these filaments and shortening of the sarcomeres, which are the basic contractile units of the muscle. As a result, the dark A bands, which...

1. What is the function of the endocrine system? The endocrine system regulates and controls various bodily functions through the production and release of hormones into the bloodstream. 2. Research two types of hormones and describe the mode of action for each. Insulin: Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. Its mode of action involves binding to specific insulin receptors on target cells, such as muscle and fat cells. Thi...

1. Compare and contrast diffusion and osmosis. Diffusion and osmosis are two processes involved in the movement of substances across cell membranes. Diffusion is the passive movement of molecules or ions from an area of higher concentration to an area of lower concentration, while osmosis specifically refers to the movement of water molecules across a selectively permeable membrane. Diffusion can occur for various types of particles, while osmosis is exclusively related to the movement of w...

Pre-Lab Questions 1. What are chromosomes made of? Chromosomes are structures composed of DNA and proteins known as chromatin. Within chromatin, there is a component called a nucleosome. 2. Compare and contrast mitosis and meiosis. Both meiosis and mitosis start with only two chromosomes and involve the creation of new cells. However, meiosis does not involve crossing over and synapsis, whereas mitosis, which occurs in somatic cells, does. Mitosis produces body cells, while meiosis produc...
