Based on your knowledge of chordate evolution, which of the following groups is MOST closely related to you (i. e., with whom have you most recently shared a common ancestor)?

a. Sea lamprey Coelacanth (a lobe-finned fish)
b. Gray treefrog (an amphibian)
c. Mudskipper (a ray-finned fish)
d. Burmese python (a snake)

The correct option is d) Burmese python (a snake)

Explanation:

Evolutionary study of chordates show that the earliest chordates were all marine animals. The evolution of marine chordates resulted in the formation of amphibians which were a transition state between marine animals and land animals. From the amphibians, reptiles and birds evolved. Studies show that reptiles and birds evolved into mammals such as the humans. Hence, as Burmese python is a reptile it will share a more common ancestor with humans.

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.
