The answer is B. When diatoms die and fall off the ocean column to the ocean floor, they become part of sediments over time. When they are mined and exposed, they turn to a diatomite. Diatomaceous earth is significant as a pest repellant because of its hygroscopic property and has very abrasive particle hence it absorbs the water-protective fats and oils from the outermost layer of insects.

Answer:
1. Signaling molecule
2. Signaling receptors
Explanation:
Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.
For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.
Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.
<h3><u>Answer;</u></h3>
Gene
<h3><u>Explanation;</u></h3>
- <em><u>A gene is a functional unit of a DNA molecule, it is a segment of DNA that contains the information that is used to generate proteins. </u></em>Each gene codes for a particular protein or in other words is used to produce a specific protein via the processes of transcription and translation.
- <em><u>By coding for a given protein, gene determines the traits or characteristics of an individual.</u></em> During the process of transcription, a process catalyzed by enzyme RNA polymerase, a gene is use to generate a messenger RNA, which then undergoes the process of translation in the cytoplasm to form proteins.
