List and describe at least two ways that similarity between organisms can be determined

1. Similarities/differences in analogous proteins

2. Comparison of DNA sequences

Explanation:

The similarities between a organism a based on their DNA sequences or amino acid sequences.they are closely related.  

Different species possess homologous structures such bones,or organs share both anatomical and  functional similarities Therefore an organism share homologous structures  have evolved from common ancestor. For instance,arm of a human being, limb of a horse,fin of  a fish, wing of a bird all are homologous structures and they perform similar functions.such as movement

eukarya because is is like alche and b is bacteria and d is animals

explanation:

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.
