The correct answer is true. Both intramembranous ossification and endochondral ossification originates from a primary ossification center. The primary ossification center, as the name implies, is the focus where the bone tissue starts ossifying. Primary ossification centers are usually found in the diaphysis of long bones or in the body of irregular bones.
Well, first off we would have more unlimited power supply and we would be able to get it easier because, the sun can produce harmful RB rays, all we would need to do is process it through a machine that can make it into a nuclear radiation rod that could be put into every electrical thing on this planet. We can also kill every one with the fire of a missile, and we could wipe the electrical currents of a nation out in one go.
Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Explanation:
Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. <u>Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them.</u> When the fluid exerts outward pressure on the cell wall it is called turgor pressure. Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.
So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.
Thereby, the turgor of a living cell is influenced by three primary factors:
- An adequate supply of water.
- The formation of osmotically substances.
- A semi-permeable membrane.
Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Answer:
<u>E. The cell's DNA is encapsulated in a nucleus.</u>
Explanation:
There are no membrane bound organelles present in a prokaryotic cell. Nucleus is a membrane bound organelle so it is absent in a Prokaryotic cell so it is an evidence that cell is Eukaryotic cell.
While other features mentioned in the question are common both in prokaryotic and eukaryotic cell.
