Viruses, although not considered to be alive, attack host cells and cause disease. the attack of a host cell is necessary for the virus to survive for all of the reasons listed except one. that is a) they cannot synthesize proteins because they lack ribosomes and must use the ribosomes of their host cells to translate viral messenger rna into new proteins. b) they cannot produce or store energy in the form of atp and have to get their energy from the host cell. c) they parasitize the host cell for basic molecules like amino acids, nucleotides, and lipids. d) they lack dna so they must use the dna of the host cell. elimin

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
