Bone cells called "Osteoclasts" break down bone by secreting hydrochloric acid and enzymes that dissolve the matrix.
Osteoclasts is "a large multinucleate bone cell that absorbs bone tissue during growth and healing"
Answer: Electron Microscope is most appriopriate for studying living cells.
Explanation:
Most of the cells are so tiny that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study the behavior of cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.
The major demerits are size, maintenance, cost, researcher training and image artifacts resulting from specimen preparation. This type of microscope is a large, cumbersome, expensive piece of equipment, strongly sensitive to vibration and external magnetic fields.
Answer:
A
Explanation:
The The one that is appropriate is A because phytoplankton to fish is like the bacteria that is on the bottom of the floor in the water and the fish could eat that phytoplankton and then your shark and whale could eat the fish and get the phytoplankton so your answer is A
Answer:
Growth hormone
Explanation:
It is called growth hormone or somatotropin or peptide hormone because it is a substance that control and is responsible for the growth and development of some essential Tissues and cells in the body.
It is secreted by the anterior lobe of the pituitary gland located at the base of the brain.
The growth hormone help children grow taller,increase body mass and help reduce body fat.
Answer:
Resulting daughter cells are smaller than the mother cell in the embryonic cell cycles
Explanation:
An embryo is an early stage of development of a multicellular organism wjich involve miosis and mitosis. Mitosis is used to produce daughter cells that are genetically identical to the parent cells which produces two daughter cells from one parent cell, during it division,shorter cell cycles occur in early embryo cells this later result to the daughter cells been smaller than the mother cell in the embryonic cell cycles
