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.
Nerve impulses are caused by Potassium (K+) and Sodium (Na+) ions that are located inside and outside of the cell. The structure of the cell membrane is permeable to Potassium but are highly impermeable to Sodium ions. These impulses are transmitted from one nerve cell to the other in very fast series.
Answer:
true
Explanation:
Embryonic stem cells.
These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
Answer
Since the whole ecosystem depends on the primary producers for survival, definitely all the sizes of the population in the ecosystem will be affected. The producers(green plants ) makes use of sunlight to supply the needed energy as food substances for the consumers ( rabbit) to feed on, and the Consumers is eaten by the top level consumers e.g Leopard.
Therefore, if the population of top level consumers is decreasing, this indicated that the secondary consumers population is reducing, due to reduction in energy obtained from primary producers which has dropped due to the decline in productivity.Hence nothing fort the top consumers to feed on.
Explanation:
The right answer is D. Clumped
A population is a set of individuals or elements sharing one or more characteristics that serve to group them together. We are talking about the population of being alive, of the human population, of the biological population ...
In this image we see three distinct groups of population (red dot) according to their position on the image.
