The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen.
Answer:
False
Explanation:
Mean arterial pressure is obtained by the following equation: (Systolic BP + Diastolic BP + Diastolic BP) / 3.
For example, the mean arterial pressure (MAP) of normal blood pressure in human beings (that is, 120/80 mmHg) would be:
(Systolic BP + Diastolic BP + Diastolic BP) / 3
120 + 80 + 80 / 3
280 / 3
93.3
This is why MAP is closer to diastolic BP than systolic BP.
Salamanders are preyed upon by garter snakes, small mammals, birds, and fish. An adult may live 6–10 years, with the largest individuals weighing approximately 7.5 grams (0.26 oz), snout to vent lengths reaching 8 cm (3.1 in), and total lengths reaching 14 cm (5.5 in).
Answer:
Cultivator.
Explanation:
Instruments such as cultivator replaced the animal drawn farm implements because these instruments works quickly and more efficiently. This cultivator has long teeth which soften the soil for better root penetration and aeration of the soil. This instrument works with high speed and finished its work in hours not days which make it more preferable in agriculture than animals.
Answer:
The correct answer is A. An ionic compound
Explanation:
Sodium (metal) and chlorine (nonmetal) form an ionic bond to each other, forming the NaCl (sodium chloride) molecule. Sodium transfers an electron to chlorine, which is missing an electron to complete the octet rule.
