Find # of electrons and draw them onto the Bohr model.
Assuming the atom has a neutral charge, the number of electrons equals the number of protons. The number of protons is given by the atomic number, 11, so there are eleven electrons.
From the inner "ring" to the outer "ring":
1. The first "ring", closest to the center of the atom, can take two electrons.
2. The second "ring", level 2, can take the next six electrons.
3. The rest of the electrons (three) can fit on the outermost ring.
Answer:
The patient will have increased blood flow and decreased blood viscosity.
Explanation:
Thinning blood makes it, for lack of better term, thinner. This means it must have a lower viscosity. (For examples of viscosity, think of pouring out a glass of water versus a glass of maple syrup. The syrup has a much higher viscosity, and will take longer.)
As demonstrated in the above example, liquids with lower viscosity flow faster. This means the patient's blood flow will increase, as it will be easier for the blood to move through capillaries and the heart won't have to push as hard to move the blood through the body.
These results correspond with answer B or D, which, at the time of this answer, are identical. Whichever answer states increased blood flow and decreased viscosity is correct.
Answer:
a. 1/2 b. The organism is an animal
Explanation:
a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?
Medullary index = diameter of medulla/diameter of hair.
Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,
Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2
b. Is this organism human or animal?
Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.
North component: y = 15.0 m * sin 55.0º = 12.3 m West component: x = 15.0 m * cos 55.0º + 7.00 m = 15.6 m
so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West
and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North
Hope this helps!
