The correct answer is option C, that is, regulate water loss.
Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.
The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.
Yes, I think I have some genetic traits which is similar to my grandparents.
Explanation:
Genes are blue print of our body. The 25% gene of Grandparent is similar to their grandchildren. This gene effects the look. It may affect the color of hair and color of eyes.
Each gene is responsible for different change of our body. Genes pass from one generation to other so it is passed through grandparents to parents and reaches to us.
Answer:
They are alike because they perform Voluntary and Involuntary Controls.
Explanation:
1). Skeletal muscle: The skeletal muscle brings about movement by pulling on the skeletal parts of which they are attached. This is the type of movement that is responsible for locomotion.
2). Smooth Muscle: This muscle is composed of elongated spindle-shaped cells which are grouped into bundles or sheets. They are least specialized muscle cells and are under the control of the autonomic nervous system.
3). Cardiac muscle: This muscle is only found in the walls of the heart. The muscle cells are branched and connected to one another by special discs. These cells helps the cells to contract and relax in unison so that the heart can pump rhythmically.
Answer:
C. lungs
Explanation:
Cystic fibrosis is a genetic disease caused by the mutation in the CF gene located on chromosome 7 which codes for the CFTR protein.
Cystic fibrosis transmembrane regulator protein or CFTR encoded protein regulates the movement of the water and chloride and sodium ions in and out of the cell.
The mutated gene forms abnormal protein which disrupts the movement of the ions and water in and out of the cell.
As a result of thick, the person develops thick and sticky mucus in the respiratory organs, especially in the lungs. Other organs of the body are also affected.
Thus, the lungs are the correct answer.
