The answer is true. Ghrelin is produced by ghrelinergic cells of the stomach. When the stomach is empty, the neuropeptide is absorbed into the blood and induces a response from the hypothalamus. The hypothalamus increases the feeling of hunger, appetite, and gastric secretion.
The layer inside Earth that creates Earth's magnetosphere is the core.

The question is incomplete as it does not have the options which are:
By binding to a plasma membrane receptor it initiates a cascade.
It relays a signal from the cytoplasm to the plasma membrane.
It activates relay proteins.
By binding to DNA it triggers the transcription of a specific gene.
It is a plasma membrane protein that binds signal molecules.
Answer:
By binding to DNA it triggers the transcription of a specific gene
Explanation:
The transcription factors are the protein molecules that bind with a specific sequence of the DNA. These transcription factors after binding to DNA initiates the process of transcription thus act in gene expression.
The transcription factors are involved in the long transduction pathway which has to act on the DNA sequence and produce the enzymes like involved in the synthesis of steroid hormones in the body.
Thus, the selected option is correct.
Answer:
1. Roche limit
2. hydrogen
3. atmosphere
4. Mercury
5. Venus
6. When an object passes the Roche limit, the strength of gravity on the object increases. If the density of the planet is higher, then the object can break up farther away from the planet. If the density is lower, then the Roche limit is located closer to the planet.
7. Farther out in the solar system, beyond the frost line, hydrogen was at a low enough temperature that it could condense. This allowed hydrogen to accumulate under gravity, eventually forming the Jovian planets.
