Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.
Answer:
Anabolic-builds large molecules from smaller ones/requires Atp
Catabolic- breaks down large molecules into smaller ones/ Produces ATP
Explanation:
Anabolic pathways are those that require energy to synthesize large molecules. Catabolic pathways are those that generate energy by breaking down larger molecules.
Explanation:
Good Samaritan Laws.
Offer legal protection to people who give reasonable assistance to those who are, or whom they believe to be, injured, ill, in peril, or otherwise incapacitated
Alcohol and drugs can alter people's judgment. They may take risks that might expose them to HIV that they would not take when sober.
Sharing needles to inject drugs (such as heroin, speed, or anabolic steroids) is VERY dangerous and can easily spread HIV (and other serious diseases) from one person to another.
Some people who are addicted to drugs may trade sex for drugs or money to get more drugs. This may put them at greater risk of HIV, especially if they do not always practice safe sex.
Answer:
The answer is B. 500
Explanation:
During normal silent breathing, approximately 500 ml of air enters and leaves the lungs at each breath. Remember that the air that enters the lungs, under normal conditions is an involuntary action that the body carries out without the person noticing. An alteration of this, produces a condition of dyspnea, sensation that the patient perceives of drowning.
