In what way are the humerus and the femur similar?
dimaraw [331]
The humerus-
A long bone of the upper forelimb. It articulates proximally with the scapula to form the soulder joint and distally with the radius and ulna to form the elbow joint.
<span>Proximally the humerus has a rounded projection known as the head. </span>

Cranially at the lateral aspect of the head is a large prominence- the greater tubercle. The lesser tubercle lies medially. Both tubercles act as a sight for muscle attachment. At the distal end of the humerus is a condyle which articulates with the radius & ulna & forms part of the elbow.

The diaphysis of the humerus is twisted.
<span>In the dog a supra condylar foramen is present- a large hole in the condyle.
</span>
The Femur-This is the thigh bone and is the largest bone in the body, it is a long bone and is similar in structure to the humerus in that it has a head, neck, shaft & lateral & medial condyles. The femoral head articulates with the acetabulum proximally to form the hip joint, lateral to the head is the greater trochanter and on the medialTh side is a lesser trochanter (for muscle attachment). At the distal end of the femur are 2 condyles that articulate with the tibia to form the stifle joint. Between the 2 condyles is the trochlear groove along which the patella can move.

Here is some information. Hope this helps ☺

Explanation:

-Q. <em>How do membrane proteins aid in the movement of hydrophilic substances across the membrane?</em>

Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across the membrane from the extracellular or intracellular space.

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Similarly via osmosis, molecules of water pass through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Transport proteins are transmembrane proteins involed in moving molecules across the membrane.

There are two types:

  1. Channels or pores are filled with water, enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration down the concentration gradient -this is a passive part of facilitated diffusion. Channels may undergo minor changes to become open or closed whereas pores are always in open states <em>e.g. H2O movement into and out of the cell via aquaporins.</em>
  2. Carrier proteins bind specifically bind to molecules and move them across or against concentration gradients. Unlike facilitated diffusion, carrier proteins directly or indirectly use energy in the form of  ATP and modify solute specific regions, that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane- this is called <em>active transport.</em> <em>e.g. Na+/K+transported by the enzyme ATPase </em>

List the quantum numbers associated with all of the 5d orbitals
Whitepunk [10]

Answer:

Here's what I get  

Explanation:

If the orbital is 5d, n = 5 and l=2.

mₗ = -l, -l + 1, -l + 2,  …., l

(mₛ is a quantum number for electrons)

Thus, we can have the following combinations.

\begin{array}{ccr}\mathbf{n} & \mathbf{l} & \mathbf{m_{l}}\\5 & 2 & -2\\5 & 2 & -1\\5 & 2 & 0\\5 & 2 & 1\\5 & 2 & 2\\\end{array}

That makes a total of five 5d orbitals.

The pictures below show what two of them look like.
