The response that is most accurate is that; with age, your arteries lose their elasticity and are replaced with collagen, which makes your arteries stiffer. Systolic hypertension or pressure is an elevated systolic blood pressure. If the systolic blood pressure is elevated (above 140) with a normal (<90) diastolic blood pressure, it is called the isolated systolic hypertension.
Answer:
a) 0.56moles
b) 2.78moles
Explanation:
The number of moles can be calculated by using the formula;
Mole (n) = Mass (M) ÷ Molar mass (MM)
For a glucose molecule, with chemical formula: C6H12O6
Where atomic mass of C= 12, H=1, O= 16
Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)
= 72 + 12 + 96
= 180g/mol
a) In 100g of glucose;
Mole = 100/180
Mole = 0.56moles
b) In 500g of glucose
Mole = 500/180
Mole = 2.78moles
Answer:
Mass number
Explanation:
Isotopes have the same number of protons and electrons but different no. Of neutrons. As mass number = protons +neutrons.
Mass number should differ.

Answer:
D, what do people need to be happy
Explanation:
first we need to understand what positive psychology means. Positive Psychology according to Wikipedia can be defined as <em>the scientific study of the "good life", or the positive aspects of the human experience that make life worth living. </em>
Therefore the correct option is D
Answer:
agouti - aaBbCc
solid color - AaBBCC
agouti black - AAbbCc
albino - AaBbcc/Aabbcc/AABBcc
Explanation: All the phenotypes that contain cc will be albinos, so they won't present any pigment deposition. Agouti black depends on the A gene to be homozygous and the B to be recessive, so the phenotype AAbbC_ is the correspondent. If A is not homozygous and B isn't recessive, we have agouti color. If B is homozygous and A recessive, we have a solid color.
