therapy would be the missing word because of the kind of cancer he has.
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
Answer:
Gram staining procedure is used to differentiate between the gram-positive and gram-negative bacteria. various reagents used in the gram staining are crystal-violet, iodine, ethanol, and safranin.
1. First, the primary strain that is crystal violet is used to stain the bacterial cells present present on the slide.
2. Then the iodine solution is added over the bacterial culture and held for 1 minute. Iodine makes a complex with the crystal violet in the cell wall of bacteria.
3. Then acetone is used as a decolorizer that decolorizes the gram-negative bacteria by dissolving its lipopolysaccharide cell wall but do not decolorize gram-positive bacteria because its cell wall is made up of peptidoglycan layer.
4. The last reagent is safranin which is used to stain decolorized gram-negative cells pink. Therefore the correct order of staining is:
Crystal violet→Iodine→acetone→sefranine
Answer:
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning.
Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually small aquatic animals—not plants. Fungi, such as mushrooms, are also said to "spawn" a white, fibrous matter that forms the matrix from which they grow
