The environment that will have a negative impact on both cells with a cell wall and cells without a cell wall is the hypertonic environment.
<h3>What is a cell wall?</h3>
A cell wall is defined as the flexible outer layer of the cell that provides protection for the cell from any physical or chemical stress.
A hypertonic fluid environment is the type of fluid that is highly concentrated than the cell.
Therefore, when a clear is placed in a hypertonic environment, through the process of osmosis, water moves out of the cell.
This affects also cells that do not possess cell wall.
Therefore, the environment that will have a negative impact on both cells with a cell wall and cells without a cell wall is the hypertonic environment.

Explanation:
Proliferative retinopathy may be described as a medical condition in which the new and weak blood start to form on retina and restores the blood supply. This condition may also develop in diabetic patient.
This is a diabetic microvascular disease that can affect the physiology of eyes. The individual has the threat to vision because new blood vessels grows on retina from the vitreous.
Thus, the answer is true.
Answer:
Active transport of calcium into the sarcoplasmic reticulum.
Explanation:
- The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+)
- In response to an action potential traveling along the t tubule, voltage-sensitive proteins change shape, opening calcium channels in the adjacent terminal cisterns of the sarcoplasmic reticulum.
