Porifera comb jellies and corals
Answer: False
Explanation:
Just because an environmental agent is not harmful does not mean that it is beneficial therefore not all non-harmful environmental agents that a pregnant woman ingests aid in the development of the fetus.
This is where the Placenta comes in. It filters out the agents and nutrients that are not needed and passes only the relevant ones to the fetus thereby ensuring that not all non-harmful agents pass through.

Answer:
- <u>Oxygen is combined with the carbon atoms left from the glucose molecule.</u>
Explanation:
Plants are producers that make polysaccharides through the process of photosynthesis. These polysaccharides, are used to store chemical energy stably in their covalent bonds.
Mitochondria break down sugars in cellular respiration. Aerobic respiration for instance, breaks down glucose in the presence of oxygen, which produces carbon dioxide and water, while transferring energy to the molecule ADP, to produce ATP (adenosine triphosphate).
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Oxygen is the final electron acceptor, it combines with the leftover carbons in respiration resulting in the waste product
.
Answer:
B
Explanation:
B: Since the drug inhibits transcription, only the mRNA that have already been transcribed can go on to be translated into the protein.
A: All proteins need Transfer RNA in order to be made.
C: Nuclear proteins are first made in the cytoplasm by ribosomes and then transported back to the nucleus via the nuclear pore complex.
D: Transcription is necessary for protein synthesis. This step cannot be skipped. Otherwise, no mRNA is made and translation cannot occur.
