Nutrients are brought to spongy bone through which mechanism?

Biology
1 answer:
Naily [24]3 years ago
5 0

if i compare compact bone, spongy bones does not contain true Haversian systems instead it  consist of an irregular lattice of thin plates of bone called trabeculae.

The spaces between trabeculae are filled with marrow. The cells of the red marrow are responsible for producing blood. Within trabeculae  lie lacunae which contain osteocytes.

 Blood vessels from the periosteum penetrate through to the spongy bone,  and osteocytes in the trabeculae are nourished directly from the blood circulating through the marrow cavities.

What evidence for the age of the Earth is indicated by the fact that sedimentary rock is found on mountain tops?
ruslelena [56]
Undisturbed rock formations on mountain tops are basically an indication of the Earth's age. This can be supported by the law of proposition. This law states that the youngest sediments or rock are found at the top of the sequence and the oldest are found at the bottom - given they're undisturbed. So the higher mountain tops or rocks formation are, the more we can say that the Earth is indeed very old.

Tina used 500 N of force to move a desk. The desk weighed 300 N, and she
larisa86 [58]

Answer:

The correct answer is - C. Multiply 500 by 1.5.

Explanation:

Given:

Force to move a desk = 500 N

weight of desk = 300 N

displacement = 1.5 meters

work done by Tine = ?

Formula:

work done (W) = F*d

where F is the force applied on the desk and d is the displacement of the desk.

Solution:

As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =

W = F*d

= 500*1.5

= 750 J

Thus, the correct answer would be option C.
