Answer:
B
Explanation:
Any drug sold in the supermarkets, convenient stores etc without prescriptions are called OTC-medication or over the counter drugs.
They are the group of drugs commonly abused by young adults. Recommendation by National Institute on Drug Abuse is that , any use of drug not related to medical purpose, but for mind-altering effects or arousal is regarded as an abuse. No doubt these drugs are obtained over the counter because they are very easy to get, very cheap and legalized by law to buy, thus easily accessible.
They drugs are high in contents which produces psychoactive effects when imbibed in over dose, and some may have damaging effects on the kidney and liver.
Other effects on the body physiology includes headaches, vomiting, nausea, seizures, tremors. etc.
Answer: Thrombus Formation
Explanation:
Atherosclerosis is a chronic, progressive disease in which the plaques starts building in the walls of artery. These plaques are the deposition of the cholesterol and other lipids, calcium and inflammatory cells known as macrophages.
Once these substances starts depositing in the artery it can lead to thrombus formation which is not cured by itself.
The Atherosclerosis is the predisposes to the thrombus formation which can cause myocardial ischemia.
Physical property is the characteristic that can be observed, using the five sense, without changing or trying to change the composition of the substance. Chemical property on the other hand is a characteristic of how the substance reacts. It can not be observed without changing the substance into something else. A physical change is a change in which the form or appearance of matter changes, but not its composition.
Answer:
Cofilin binds to older actin filaments
Explanation:
Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
