<u>Bone tissue</u>
You are observing a tissue under the microscope and notice dark concentric circles of matrix and osteocytes in lacunae. You identify this tissue as <u>bone tissue.</u>
<u></u>
<h3>What does bone tissue look like?</h3>
- Osteons or haversian systems are tightly packed together to form compact bone.
- The osteon is made up of concentric rings (lamellae) of matrix surrounding a central canal known as the osteonic (haversian) canal.
- The bone cells (osteocytes), which are situated between the rings of matrix, are found in regions known as lacunae.
<h3>Which 4 tissues are present in bones?</h3>
- Osteoblasts, osteocytes, osteoclasts, and osteogenic cells are the four types of bone cells that make up bone tissues.
<h3>How does bone tissue develop?</h3>
- The recruitment and growth of bone progenitor cells from neighboring tissues is the first step in the development of bone tissue.
- Next come differentiation, matrix production, and mineralization.

Answer:
chips made from silicon
Explanation:
Non renewable resources are natural substances that cannot be replenished when used for eg natural gas, coal, petroleum ,fossil fuels etc. Silicon is made when silica is heated with carbon after which the the product is reacted with hydrocarbons to polymerize them. Since the hydrocarbons are made from natural gas, oil ,it is non renewable

Answer:
The statement that best represents a function of lipids within an organism is that they are components of cell membranes.
Explanation:
Lipids are biomolecules formed by the binding of fatty acids, important for structure, compound synthesis and energy reserve.
In living beings, one of the most important functions of lipids is to be the main component of cell membranes.
Specifically, phospholipids associate to form a double layer, called lipid bilayer, capable of acting as a semi-permeable membrane, due to its non-polar or hydrophobic character. In this way, <u>membrane lipids fulfill a structural and protective function of the cell and its contents</u>.
Regarding the other options:
- <em>Proteins are made up of amino acids, not lipids.
</em>
- <em>Lipids are not constituents of the DNA structure.</em>
The answer should be B may be wrong
