Brendan made a chart to categorize the characteristics of animals. which phrase should be written in the column titled “sometimes”?

a. are multicellular

b. have membrane-bound organelles

c. produce their own food

d. display an asymmetrical body plan

D. display an asymmetrical body plan

Explanation:

Most of the animals have bilateral symmetry but sometimes animals show asymmetrical body plan.

Rest of the options are wrong.

Animals are always multicellular and there is no exception to this fact. So, if we will write  sometimes animals are multicellular, it will be a wrong statement.

Animals are eukaryotic organisms so it means that they must have membrane-bound organelles .The organisms which do not have membrane-bound organelles  are known as prokaryotes but animals are eukaryotes. So B statement is wrong.

All the animals are heterotrophs that means that animals cannot produce their own food in any situation so statement C is also wrong.

the answer is b)3/8x+1

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
