Answer:
c. The cells of all organisms contain DNA that is housed in a membrane-bound nucleus.
Explanation:
DNA is the genetic material found in the cells of living organisms. Among the characteristics of the DNA that makes up the genetic code, it is said to be nearly universal though. DNA is said to be the "blueprint of life".
This means that the DNA sequence that encodes protein and useful information is the same in almost all living organisms. Hence, the statement that "cells of all organisms contain DNA that is housed in a membrane-bound nucleus is the" justification that fact that all organisms share some basic features and life processes is used by biologists to explain the idea that all life.
A food chain can usually sustain no more than six energy transfers before all the energy is used up. And so less energy is transferred at each level of the food chain so the biomass gets smaller.
I think the correct answer from the choices listed above is the first option. The sequence that is arranged from the simplest one to the most complex would be:
<span>squamous cell → epithelial tissue → skin → integumentary system → human

The sequence should start with a single cell, group of cells which makes a tissue, group of tissue, system and the whole body.
