Really need ! the external coverings of diatoms are made up of [blank1], while slime molds have cell walls containing [blank2]. diatoms are [blank3] because they make food through photosynthesis, while slime molds are [blank4] because they eat decaying plant matter. 1st blank: peptidoglycan, silica, chitin 2nd blank: peptidoglycan, silica, chitin 3rd blank: photoautotrophs, chemoheterothrophs, chemautotrophs 4th blank: heterotrophs, autotrophs, phototrophs

The correct terms for the blanks are - blank1: silica, blank2: chitin, blank3: photoautotrophs, blank4: heterotrophs.

Explanation:

Diatoms are photoautotrophic algae, they have a skeleton made up of silica. Diatoms are found in nearly every aquatic environment. They are photosynthesizing algae that make their own food.

Slime molds are heterotropic in nature like protozoa and were formerly classified as fungi but are now placed in protists.

Thus, the correct terms are - blank1: silica, blank2: chitin, blank3: photoautotrophs, blank4: heterotrophs.

the right answer is a. skin cells forming from sunlight.

the liver is an organ endowed with a fantastic ability to regenerate

. thus, if a hepatectomy (ablation) of 70% of the hepatic mass is performed in the rat, there is complete recovery in 7 to 10 days.

prokaryotes are beings that have existed since the existence of life on earth, and do not come from another realm.

ribosomes are organelles that exist naturally in eukaryotes, either in free form or attached to the endoplasmic reticulum.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
