The mechanical advantage of a lever is 4 What does it mean?​

Answers

Answer 1

Answer:

Mechanical advantage MA is the ratio of output (generated by the machine)force to intput (applied to the machine) force. So MA=4 means that for example if you apply 100N then your machine will multiply that force and generate 400N.

The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process within the cell.

Answers

Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.

When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.

The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.

The ribosome represents the actual site of protein synthesis.The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.

In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.

The eukaryotic cells have cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.

It has mitochondria energy house, a cytoskeleton for structure and passes information, and  lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.
