Hello again. Let me explain
Explanation:
It has many function I will name at least two of them:It protects the plant from microbes like bacteria and viruses. It makes the cell strong so it wont chnge its shape alot so the plant will stand vertically without any bone or other things. It controls passing molecules like Glucose or amino acid..In torgesans of the cell the cell wall will protect the cell against exploding.I think thats enough.
Answer:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

can someone write a 5 sentence summary on ER plzzz
Answer:
Endoplasmic Reticulum
Explanation:
1. Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
2.Control is exerted within a network of membranes called endoplasmic reticulum (ER ), which transports proteins throughout the cell. Don't forget ribosomes, the golgi apparatus and endoplasmic reticulum. The outer membrane is continuous with the rough endoplasmic reticulum.
3.While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA. Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.

What causes genetic mutations? You must use the following terms: gene, protein, trait
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
Explanation:
Answer:
Genetic variations can arise from gene mutations or from genetic recombination (a normal process in which genetic material is rearranged as a cell is getting ready to divide). These variations often alter gene activity or protein function, which can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
