What cell parts are common to all of these cells?
Use complete sentences.

Chlamydomonas
Spirogyra
Elodea
Squamous Epithelium

Answer: All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4). The cells of most Chlamydomonas species are more or less oval and feature a noncellulosic membrane (theca), a stigma (eyespot), and a usually cup-shaped chloroplast. Although photosynthesis occurs, nutrients also may be absorbed through the cell surface. Asexual reproduction is by zoospores.  The filamentous masses come to the surface and become visible as slimy green mats. Spirogyra has a cell wall, nucleus, pyrenoid and spiral chloroplasts.  This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. brainliest?

Explanation:

Builder a was able to underbid his competitor, builder b, by secretly using a lower grade cement when building swimming pools.both builders used the same design and specifications for the pool.

Which of the following mutations could lead to constitutive expression of the genes of the lac operon? View Available Hint(s) Which of the following mutations could lead to constitutive expression of the genes of the lac operon? A mutation in the lac-Z gene A mutation in the lac-Y gene A mutation in the operator sequence A super repressor mutation Submit Part B Which of the following best describes the biological role of the lac operon? View Available Hint(s) Which of the following best describes the biological role of the lac operon? It ensures that bacterial cells produce lactose only when no other food sources are available. It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment. It ensures that a cell produces enzymes involved in lactose metabolism in a constitutive manner. It prevents other sugars from being metabolized until all available lactose has been used. Submit Part C The placement of the operator sequence between the promotor and the structural genes is critical to the proper function of the lac operon. View Available Hint(s) The placement of the operator sequence between the promotor and the structural genes is critical to the proper function of the lac operon. True False
