Answer:
(I am also a girl) Just keep some pepper spray on you. If you have a phone you can have it on you just either keep it out of sight or in a safe place within reach so if you need to you can call for an emergency. I bet you are beautiful, but if you are self-conscious I don't really know what to tell you other than try ignoring stares or what other people say it doesn't matter what other people think about you it only matters what you think of yourself. Also if someone ends up grabbing you kick and scream as loud as you can. Try hurting them to get out of their grasp. When you get out of their grasp, DO NOT run home, run to the nearest police station or to a stranger's house and tell them you need help.
Explanation:
I hope this helps you get over those feelings :) wish you the best.
Cell surface or membrane is made of phospholipid bilayer with embedded proteins and sugars. Cell membrane acts as a barrier between cell and its external environment but it is also responsible for the communication with other cells and transport of molecules inside and outside the cell. It is selectively permeable to ions and molecules (some of them pass through the membrane easily, while others require transport proteins or channels). There are 4 ways of molecule transport:
1. Diffusion – no energy required
2. Facilitated transport – transport proteins included
3. Active and co-transport – energy required
4. Vesicle transport (exocytosis and endocytosis)
Microvilli are extensions of cell membrane that increase its surface for diffusion.
Different types of cell junctions have a different influence on the membrane transport. For example, tight junctions are a barrier and the molecules are unable to pass through.
The correct answer is macrophage.
<span>The macrophage is a type of white blood cells with phagocyte activity which means its main function is to “eat” foreign particles such as bacteria. A macrophage has the ability to locate those particles (viruses, parasites, fungi, bacteria) and do the cleanup.</span>
Answer:
Brain stroke (Cerebrovascular Accident)
Explanation:
The blood is supplied to anterior areas of brain by carotid arteries and to the posterior areas of brain by vertebral arteries. The dysfunction of brain after stroke depends upon the corresponding brain area associated with blocked artery. The middle cerebral artery (found in cerebrum portion of brain) is most commonly blocked in stroke.
Stroke occurs when brain cells are deprived of oxygen due to the lack of blood cell. There are several type of strokes. It may be caused by the blockage of blood vessels due to depositions of cholesterol in blood vessels. It hardened the walls of blood vessels and narrow them causing hindrance in the blood flow. If this clot remain at one place it is known as ischemic stroke and if it can convert to embolus and travel across the body it would cause the embolic stroke.
Haemorrhagic stroke is caused due to rupturing of one of the blood vessel and it is the most crucial form of stroke.
