Answer:
Is composed of trabeculae that are oriented along lines of stress. (Ans. D)
Explanation:
Spongy bones are also known as trabecular and cancellous bones. It is covered by compact bones and present in the long bones. They are known as spongy because they are highly vascular and porous tissues.
Osteoblast thin area creating the turbeculae space between the tissues. Spongy bones are also known for home of hematopoietic stem cells and bone marrow, which are helping to differentiate white blood cells, red blood cells, and platelets.
Some difference between spongy bone and compact bone are:
1) Spongy bones are light weight and compact bones are heavy.
2) Spongy bones are composed of trabeculae and compact bones are composed of osteons.
3) Spongy bones are known as cancellous and compact bones are known as cortical bones.
Organisms that are characterized by being unicellular, photosynthetic, and having double shells made of silica are known as B. diatoms.
<h3>Photosynthetic</h3>
By converting light energy into chemical energy through a process called photosynthesis, plants and other living things can subsequently release that chemical energy to power their activities. The name "photosynthesis" comes from the Greek words "phs" for "light" and "synthesis" for "putting together." Some of this chemical energy is stored in carbohydrate molecules like sugar and starch, which are created from carbon dioxide and water. These creatures are referred to as photoautotrophs and include the majority of plants, algae, and cyanobacteria. Most of the energy required for life on Earth is produced and maintained through photosynthesis, which also produces and maintains the oxygen concentration of the atmosphere.
Organisms that are characterized by being unicellular, photosynthetic, and having double shells made of silica are known as
A. dinoflagellates.
