Answer:

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.

Proximally the humerus has a rounded projection known as the head.

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.

In the dog a supra condylar foramen is present- a large hole in the condyle.

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.

Answer:

Hypotonic solution

Explanation:

hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.

isotonic solution is the one you get when the solute concentration of the cell and the water are the same.

hypotonic is the one that you get when the solute concentration of the cell is higher than that of the waters.

Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.

sorry if the grammer is bad i tried my best.

Why do lipophilic hormones require carrier proteins while being transported in the blood?

valina [46]

Lipophilic hormones, intuitive as the name suggests, tend to dissolve well in lipids/fats than they do in water. Therefore lipophilic hormone does not dissolve well in blood plasma which would affect their diffusion. The carrier proteins are mainly the serum albumins.

Answer:

The correct answer is option C.

Explanation:

As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:

A a

A AA Aa

a Aa aa

Genotype: AA: Aa: aa :: 1:2:1

Phenotype: Dominant: recessive :: 3:1

What the function if animal cell divide without centrioles?

Vesna [10]

Answer:

spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division.

Explanation:

They play a role in mitosis of animal cells and plant cells are able to reproduce without them.

Research however has shown that mitosis can take place in animal cells after centrioles have been destroyed. ... In higher plants mitosis takes place perfectly satisfactorily with microtubules forming spindle fibres but without the help of centrioles.

Hope this helpse!! Brainliest?? Anyways have a great day my loves<3
