The answer is guard cells.
Guard cells are cells surrounding each stoma. They help regulate the rate of transpiration by opening and closing the stomata. They are specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore (stoma).
The abiotic environment consists of non-living things. So, rocks, temperature and water are part of the abiotic environment.
A function of the cell structure that it provides support to labeled x .
What is the function of cell?
- They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
- Additionally, cells have the ability to replicate themselves and contain the body's genetic material.
- Each component of a cell has a different purpose.
What is cell structure and function?
- Cell architecture - Individual parts of the cell structure each have a specific purpose that is necessary to carry out life's processes.
- Cell wall, cell membrane, cytoplasm, nucleus, and cell organelles are some of these elements.

3 Major Functions of a Cell -
- Energy Generation.- Living cells exist in a perpetually active biological state. .
- Molecular Transport - Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell.
- Reproduction.

Answer:
7
Explanation:
There are 12 total pairs of ribs. 1-7 are attached directly to the sternum by costal cartilages, making them true pairs. 8-10 are fake pairs, which means they're attached indirectly to the sternum. And 11 and 12 and free floating ribs, meaning they aren't attached.
When exercise does not increase bone mass, it has been observed that the risk of bone fractures increases due to osteoporosis.
<h3>What are the benefits of exercise to bone mass and density?</h3>
Bone mass refers to the mass of the bones in a living organism as a result of the deposition of minerals within the bone.
An increase in bone mass is directly related to the strength of the bone.
Strong bones have high bone masses whereas weak bone have low bone mass.
Physical activity have been shown to improve bone mass by increase the mass of deposited minerals in the bone.
Exercise such as walking, running, jogging, and other forms of exercise have been shown to improve bone mass and hence, the strength of bones.
However, when exercise does not increase bone mass, osteoporosis is observed which results in bone fracture.
In conclusion, the strength of a bone is directly related to the bone mass which is directly related to the mass of minerals deposited within them.
