Essay Question 1 Explain how changes in habitat can lead to habitat fragmentation. How does this affect the population of animals in that area? Species lose their habitats when those habitats are destroyed outright‚ but habitat loss also occurs when habitats are altered through more subtle processes‚ including fragmentation and other forms of degradation. The sudden and complete elimination of habitat is uncommon at large scales; instead‚ what we usually witness is gradual‚ piecemeal degradation

• Chapter 7 o Online questions • The fluid mosaic model is now generally accepted for the description of all biological membranes • Transmembrane segments of membrane proteins anchor membrane proteins in the lipid bilayer. • A ganglioside is not a phospholipid. • Thin-layer chromatography separates lipids based on hydrophobicity. • Unsaturated fatty acids have double bonds and increased membrane fluidity. • Cholesterol increases fluidity at low temperatures and decreases fluidity at high temperatures

After months of research and experiments‚ I have concluded my discovery of space worm touch receptors is definite. Regardless of the type‚ sensory receptors are influenced by physical actions and various stimulus. My research and experiments show that space worm touch receptors are no different. Stimulus is a change discernible by the body (Sherwood 2004) or in my case‚ a space worm. Certain receptors like touch receptors respond to stimulus weakly or strongly when involved with a different stimulus

1. Discuss how to protect yourself from body fluids‚ such as saliva and blood. o Gloves protect you whenever you touch blood‚ body fluids. The use of gloves also decreases the risk of disease transmission if you are pricked with a needle. Always wear gloves for handling items or surfaces soiled with blood or body fluids. o Wash your hands and other skin surfaces immediately after they come in contact with blood or body fluids. o Masks and protective eyewear‚ such as goggles or a face shield

Resistant starch (RS) is starch and starch degradation products that escape from digestion in the small intestine of healthy individuals.[1] Resistant starch is considered the third type of dietary fiber‚ as it can deliver some of the benefits of insoluble fiber and some of the benefits of soluble fiber. Some carbohydrates‚ such as sugars and most starch‚ are rapidly digested and absorbed as glucose into the body through the small intestine and subsequently used for short-term energy needs or stored

Mutualism of a Bengal Tiger- A very powerful antibiotic‚ Bacilli is a type of bacteria belonging to the Enterobacteriaceae family. Specifically‚ Pantoea agglomerans of the bacilli family are helpful by producing a broad spectrum antibiotic andrimid. This kills many harmful bacteria that a tiger may ingest from its prey by blocking a critical step in fatty acid biosynthesis. This helps protect the tiger from such dangers like E. coli and samonella poisoning. Parasitism-An example of parasitism is
