Explanation:
<h3>Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, HF,NH3,H2O shows hydrogen bonding.The hydrogen bond does not form because the chlorine atom is too large. Despite chlorine's high electronegativity its big size lowers the negative charge density and it is not enough to attract a hydrogen atom in a stable phase. Nevertheless, there is a small dipole-dipole attraction between adjacent HCL molecules.</h3>

The principle of states that the physical, chemical, and biological processes at work shaping the earth today have also operated in the geologic past is uniformitarianism.
<h3>What is
biological system?</h3>
- A biological system is a complex network which connects several biologically relevant entities.
- Biological organization spans several scales and are determined based different structures depending on what the system is.
- Examples of biological systems at the macro scale are populations of organisms.
- On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the nervous system.
- On the micro to the nanoscopic scale, examples of biological systems are cells, organelles, macromolecular complexes and regulatory pathways.
- A biological system is not to be confused with a living system, such as a living organism.
<h3>What in nature is biological?</h3>
- All of the branches of the natural sciences that focus on different facets of life's processes are included in the biological sciences.
- The notion spans all species, from bacteria to animals and plants, and incorporates anatomy, physiology, cell biology, biochemistry, and biophysics.

When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression
Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.
If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.
However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.
