Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
Answer:
True.
Explanation:
The diaphragm is like a pump; to bring in air, it opens up, pulling air in. To release it, it closes back down, forcing air out.
Answer:
The correct sequence of events in protein synthesis is transcription then translation. First, during transcription DNA is copied to mRNA in the nucleus. Then, mRNA is edited, processed and exported to the cytoplasm. Next, translation occurs.
Explanation:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein. The process in which the messenger RNA (mRNA) molecule on a ribosome is decoded to produce a sequence of amino acids for protein synthesis. The process in which a strand of messenger RNA (mRNA) is synthesized by using the genetic information found on a strand DNA as a template.
Answer:
Bed bugs belong to the Cimicidae family (that's Latin for bloodsucking wingless bugs). They come in the order of Hemiptera.
Answer:
The correct answer is option A. "Culture B will have more colonies on the histidine-minus plate than culture A".
Explanation:
In this example, Culture B is a culture of E. coli that has been exposed to a mutagenic agent, therefore it has the potential of developing bacteria that by chance, is able to live in a medium lacking histidine. On the other hand, Culture A is the same E. coli culture but without the exposure to the mutagenic agent. The expected result is that Culture B will have more colonies on the histidine-minus plate than culture A, illustrating that a mutagenic agent can produce E. coli able to reproduce in a histidine-minus plate.
