<h2>Answer is option "D"</h2>
Explanation:
- If a meteoroid draws near enough to the Earth that it enters our environment, it starts to set up and fall to the ground
- This consuming path is known as a meteor.
- They are generally splendid in shading and leave an excellent path of light in the sky.
- A few people call them meteorites, however they are aren't generally stars, simply modest lumps of rock wrecking in the Earth's environment!
- In the event that a meteoroid rock doesn't totally wreck as it tumbles to Earth - the stone that is abandoned is known as a shooting star.
- In spite of the fact that meteors and comets both make brilliant path during our time sky, they are totally different.
- Meteoroids are protests in space that run in size from dust grains to little space rocks. Consider them "space rocks."
- Hence, the correct answer is option D "Meteor"
Complete question: A hydrophilic peptide hormone is produced in the anterior pituitary gland located at the base of the brain. The hormone targets specific cells in many parts of the body.
Which of the following best explains a possible mechanism that would enable the hormone to efficiently reach all of the target cells in the body? answer choices
A. The hormone interacts with the nerves at the base of the brain and directs signals to the target cells through the nervous system.
B. The hormone diffuses into target cells adjacent to the anterior pituitary gland, where the hormone is degraded.
C. The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.
D. The hormone moves through cytoplasmic connections between cells until it has reached all cells with the correct intracellular binding sites.
Answer: (C) The hormone is released into the bloodstream where it can be transported to all cells with the correct receptors.
Explanation: Hydrophilic peptide hormone is secreted in the anterior pituitary gland, which is in a form of chemical signals or ions. These signals are secreted into the bloodstream (duct) and are passed through the blood to get to a target organ, which possess cells signalling the appropriate receptor that binds to the chemical messenger (ligand), then signal transduction is established.
The correct answer for this question would be option B. Systematists categorize all living creatures into three domains namely bacteria, archaea and eukarya. This is a<span>ccording to the Woese system which is introduced in 1990. Both Archaea and Bacteria are classified as prokaryotes or single-celled organisms. Hope this answer helps.</span>
The aerosol can is sealed, and under pressure. Place it on a heat source, and the gas inside expands. Upon expansion with no outlet, the vessel may explode.
Pressure cookers work on this principle, as food can be cooked at higher temperatures than
100
∘
C
. Pressure cookers have safety valves, that will operate if the internal pressure becomes too high.
