I think the correct answer from the choices listed above is option C. The function that is both performed by goblet cells and lacrimal glands is protection. They produce mucus in order to protect mucous membranes. Hope this answers the question.
Similarities:
They contain nematocyst (cells that sting)
some are sessil/free swimming
Some corals have a symbiotic relationship with algae, they need to grow in shallow waters so that light can penetrate for the algae to photosynthesize.
The given statement is False.
The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.
The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.
The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
Answer:
To make proteins, DNA transcribes information into RNA in the nucleus. Transcription is like making copies of the information from DNA and applying this information in a new format. The RNA exits the nucleus and travels through the cytoplasm to ribosomes on the rough endoplasmic reticulum
