C. their magnetic domains are arranged randomly
In magnetized materials, all or most of the magnetic domains are arranged in the same direction
The electron transport system in the light dependent reaction of photosynthesis is the one that is responsible for the production of electrons that are used as precursor for NADPH production. The NADPH and the other products that are made during the light dependent reaction are used during the dark reaction to produce sugar molecules. So, if the electron transport is disabled, glucose molecule will not be produced during the dark reaction.<span />
Protista Organisms are most closely related to Archeabacteria.
Answer:
A. Porifera
Explanation:
Parazoan is a sub-kingdom of animal consisting only of the phylum of sponges (porifera), having two tissue layers only and lacking a nervous system and true digestive cavity.
They have certain characteristics like: sponges are marine, but there are some freshwater sponges that enjoy their water without salt. Most sponges do not have any type of symmetry, but some are radially symmetrical and they come in a variety of shapes, colors, and sizes, they are multicellular, heterotrophic and lack cell walls. Unlike other organisms, sponges lack true tissues and organs.
The mesohyl functions as an endoskeleton in most sponges, and is the only skeleton in soft sponges. This mesohyl is stiffened by mineral spicules, by spongin fibers or both.
