Resorbing or breaking down bone matrix are the responsibilities of Osteoclasts. It is a balance between bone production and bone absorption into the circulation of tissue or cells which is obligatory for remodeling and re-establishing the skeleton. Osteocytes are mature osteoblasts – a cell that produces and discharge a substance for bone formation.
Answer: Similarities in amino acid sequence strongly suggest common ancestry
Explanation:
The chemical make-up and biochemical process of all organisms are as very similar. For example, all organisms
- are build up of the same types of complex molecules such as carbohydrates, lipids, proteins (polymers of amino acids) and nucleic acids
This similarity strongly suggest common ancestry for all organisms, thus leading to evolution of individual species
Is this it?
<u><em>After egg hatches, the immature insect feeds and grows. Its exoskeleton is like a shell. Eventually, the larva or nymph must shed its unyielding overcoat to continue its development.
</em></u>
<u><em>
</em></u>
<u><em>The exoskeleton which serves as its external backbone is used for protection and support. Without an exoskeleton, the insect could not survive. An old exoskeleton is shed when a new one is ready underneath, a process that can take days or weeks.</em></u>
Answer:
C. channel protein - allow passage of material through the hydrophilic pore
Explanation:
Channel Protein is a transport protein that has an aqueous channel throughout its transmembrane molecule, which allows the free movement of certain ions or molecules through diffusion, allowing these materials to pass through the hydrophilic pore.
From this we can conclude that the correct answer to your question is the letter C.
