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.

So as to protect species, it a habitats and ecosystems
Answer:
A. It releases them into the environment through its cell membrane.
Explanation:

Answer:
an extinct plant or animal
Explanation:
Fossils of an animal or plant refers to its preserved or mineralized remains. Fossils have proven to be an integral part of tracing life back. Among the very many usefulness of keeping fossil records of plant and animals, one of them is discovering the evolutionary relationships between these organisms.
Fossils of plants or animals are compared with that of a present organism to discover how related they are. However, a difficulty that arises during this comparative procedure is that the fossils about to be compared may be from an extinct plant or animal.
A. Males produce four functional sperm while females produce only one functional egg.
