The correct answer is D Fish ( someone asked me to explain why d is the answer) A sponge obviously doesn’t have a brain, a hydra is an organism and organisms don’t have brains ( hydra also doesn’t have eyes)
Answer:
C
Explanation:
all of them have negative effects on the enviroment as a whole but C gives no reason why it would be a consequence
Answer:
fertilized egg
Explanation:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Answer:
chloroplasts and mitochondria.
Explanation:
Chloroplasts and mitochondria are the organelles capable of ATP production by photophosphorylation and oxidative phosphorylation respectively. Chloroplasts are the site for photosynthesis. The light reactions of photosynthesis include splitting of the water molecule in presence of sunlight and transfer of electrons from PS-II to PS-I via electron carrier. During electron transport, a proton gradient is created which in turn drives ATP synthesis.
Mitochondria are the site for aerobic stages of cellular respiration. Glycolysis and Kreb's cycle, the first and second stages of cellular respiration produce NADH and FADH2 during the redox reactions. These reducing powers are oxidized by giving their electrons to the terminal electron acceptor, the oxygen molecule.
Electrons from the reducing powers are carried to oxygen molecules via a series of electron carrier proteins embedded in the inner mitochondrial membrane. During electron transport, an electrochemical gradient is created which in turn drives the ATP synthesis.
