Answer:
The external coverings of diatoms are made up <u>silica </u>, while slime molds have cell walls containing <u>cellulose.</u> Diatoms are <u>photoautotrophs</u> because they make food through photosynthesis, while slime molds are <u>heterotrophs</u>.
Explanation:
Diatoms can be described as algae that are mostly single-celled. They are made up of a unique kind of cell wall composed of silica. This cell wall is termed as a frustule. Mostly, diatoms are capable of carrying out photosynthesis and hence make their own food.
Slime moulds can be described as organisms that are fungus-like protists. They are not capable of producing their own food and feed on other plants. Hence, they are heterotrophs.
Mixtures can be separated my physical means is true
mixtures are made up of more than one component is true
all else is false I believe
Halophiles are extremophiles that thrive in environments with very high concentrations of salt. <span>Halophiles prevent this loss of water by increasing the internal osmolarity of the cell by accumulating </span>osmoprotectants<span> or by the selective uptake of potassium ions. Hope this helps.</span>

Explanation: Saturated fatty acids have single carbon-to-carbon bonds. Therefore, saturated fatty acids have straight structures while unsaturated fatty acids have bent structures. Saturated fatty acids are solid at room temperature and unsaturated fatty acids are liquid at room temperature.
