Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
Answer:
Cleavage and fracture are not commonly used to identify minerals
Las paredes externas de una casa o un automóvil brindan una barrera fuerte e inflexible que protege a sus habitantes humanos de un mundo externo rudo e impredecible. Podría esperarse que el límite externo de una célula viva estuviera construido de una barrera igual de fuerte e impenetrable porque también debe proteger su delicado contenido interno ante un ambiente no vivo y a menudo inhospitalario. Sin embargo, las células están separadas del mundo externo por una estructura delgada y frágil llamada membrana plasmática que sólo mide 5 a 10 nm de espesor. Se requerirían casi 5 000 membranas plasmáticas apiladas una sobre otra para igualar el grosor de una sola página de este libro.
The appropriate title of the scatter plot is solubility curve of sugar
The independent variable is temperature
The dependent variable is mass of sugar in grams that can dissolve in 100 mL of water
The solubility curve is a graph of the amount of solute dissolved in a given volume of solvent against temperature.
The solubility of the solute is plotted on the vertical axis while the temperature is plotted on the horizontal axis.
The independent variable is the temperature while the dependent variable is mass of sugar in grams that can dissolve in 100 mL of water.

Answer:
A magnet keeps a cabinet door closed. The Sun pulls on Earth as Earth moves around the Sun. The protons in the nucleus of a carbon atom are held together.So this is an example of the strong force in action.
