Nutrients are brought to spongy bone by diffusion through canaliculi
- Diffusion through the canaliculi
<h3>How is bone tissue nourished?</h3>
Nutrition is provided by the so-called Nourishing Foramina, which are openings in the bone through which blood vessels, veins and arteries pass. Also with regard to nutrition, Volkmann's canals provide the main entry route for vessels to cross compact bone.
With this information, we can conclude that Volkmann canals also contain nutritional vessels arising from the periosteal and endosteal bone surface.

Answer:
Enzymes are proteins that are able to increase the rate of a reaction without being consumed by the reaction. They are also called natural catalysts.
Explanation:
Enzymes increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed.
Hope this will help :)
Answer:
1.27 hour or 77 minutes.
Explanation:
In the given question it is provided that:
1. DNA polymerase III synthesizes new DNA at a rate of- 1000 bases/sec
2. The genome of E.coli has- 4,600,000 base pairs
To calculate the time required for replication:
Total base pairs/ speed of enzyme
= 4600000/1000
= 4600 seconds
= 4600/3600 (1 hour= 3600 seconds)
= 1.27 hour or 77 minutes.
Thus, 1.27 hour or 77 minutes is correct.
