Assess the following statements, and classify them according to whether they refer to viral particles or living cells.
o may have a cell wall
o genome may be exclusively rna
o center layer is predominate protein
o contain ribosomes
o are obligate parasites
o always have a plasma

Characteristics of viral particles from the options given are;

1. Parasitic obligate.

2. The centre layer is predominate protein.

3.Genome may be RNA exclusively.

The characteristics of living cells are:

1 . May have cell wall.

2. Contain ribosomes.

3. Always of plasma.

Explanation:

Living cells are the basic unit of life, that contain the fundamental molecules in which the living things are composed of. Living cells have plasma membrane, ribosomes, cytoplasm and DNA.

Viral particle is a structure or infectious agents that enter another cell and replicates itself in a living cell. The are obligates parasite, that have no cell wall, they have center layer of protein, the genome contain either DNA or RNA, they reproduce only in living cells, they lack cytoplasm and organelles.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic
