Answer:
The correct answer would be - 120/88 or 112/80
Explanation:
Pulse pressure or PP is the difference between the top or higher number (systolic) and the bottom number (diastolic) blood pressure. Pulse pressure can find out by the systolic minus the diastolic of Blood pressure.
For example, if an individual's resting BP is 120/80 millimeters of mercury (mm Hg), the normal PP is 40 which is considered a healthy pulse pressure. So, as per the normal BP 120/80, if the pp was 32 than the bp would be 120/88 or 112/80.
Answer: Option A) True
The statement is true
Explanation:
Impulses of motor neurons could inhibit the cells of the effector (e.g skeletal muscles, gland). Hence, the axons cause the release of glycine which inhibits or checks muscular contractions.
The letter A in the diagram represents genes
Answer:by moving against each other causing the surfy to change over time
Explanation:
The body's first line of defense is actually the non-specific immune system which is also called innate immunity.
Innate immunity employs both physical and chemical barriers that form the first line of defense. These include:
1. The intact skin. The skin is made up of keratin in its outermost layer. Keratin makes skin tough and resistant and pathogens usually cannot penetrate unless the skin is broken.
2. The mucus membrane. This is a thin membrane that forms a protective lining inside many organs and other parts of the body such as the trachea. Mucus produced by the membrane traps bacteria and other harmful particle which are then expelled from the body.
3. Tears. Tears from our eyes contain lysozyme, a chemical that kills bacteria.
If the pathogen gets through or evades these types of defenses, then it is dealt with by the second line of defense which is called specific immunity or acquired immunity. It is here that white blood cells namely the B lymphocytes and T lymphocytes attack, kill or neutralize pathogens.
