Answer:
Common symptoms of musculoskeletal disorders include pain, weakness, stiffness, joint noises, and decreased range of motion. Inflammation may cause pain, swelling, warmth, tenderness, impaired function, and sometimes redness of the overlying skin.
Includes Diseases: Rheumatoid arthritis
Explanation:
A. A <u>wind vane</u> measures the wind direction and <u>anemometer</u> measures the wind speed.
B. When rising air cools, it can lead to clouds and precipitation because cool air can hold less water vapor.
C. Sinking air <u>warms</u> and causes evaporation of clouds, thus fair weather
D. Isobars means bars of equal pressure, ‘iso’ meaning ‘equal’ and ‘bar’ representing a unit of pressure, so together isobar means bars of equal pressure. Isobars or lines of equal pressure may be packed together indicating a <u>strong</u> pressure gradient
E. Pressure gradient is the difference in pressure between high and low pressure areas. The strongest winds are in areas where the pressure gradient is the <u>greatest</u>.
Explanation:
A wind vane is an instrument which spins according to the wind direction.
An anemometer is a meteorological instrument that measures the wind speed, direction and pressure.
Rising air cools while the sinking air warms according to the adiabatic cooling/warming principles. Warm air holds more moisture than cold air.
Isobars are unique features on a weather map represented by lines connecting areas with equal pressure gradients. According to the pressure gradients, the isobar spacing is arranged.
The 31 spinal nerve pairs are organized geographically by spinal region. There are eight pairs of cervical nerves (C1-C8), twelve pairs of thoracic nerves (T1-T12), five pairs of lumbar nerves (L1-L5), five pairs of sacral (S1-S5), and one pair of coccygeal nerves.
<h3>What number of nerves make up a pair?</h3>
The cranial nerves, a collection of 12 paired nerves, are located at the back of your brain. Your cranial nerves transmit electrical signals to your brain, face, neck, and body.
<h3>What are the 31 pairs of spinal nerves used for?</h3>
The peripheral nervous system, which consists of 12 cranial nerves and 31 pairs of spinal nerves, transmits nerve impulses from the central nervous system (CNS) to the rest of the body to control bodily activities.

Answer:
The above paragraphs describes that how salt- and fresh-water fish regulates their osmoregulation. Hence, the correct answer would be c. have adapted to deal with osmosis.
Osmosis is the process by which solvent's molecule move from region of low concentration (hypo-tonic) to the region of high concentration (hyper-tonic) through a semi-permeable membrane.
In sea-water fishes, the body fluids are hypo-tonic to the surrounding water and thus water is kept moving out of their gills. In order to prevent the excess water loss they need to drink water constantly and excrete concentrated urine.
In contrast, fresh-water fishes body fluids are hyper-tonic to surrounding water and hence, water keeps entering in their body through gills. So, in order to prevent excess dilution they absorb salt from surrounding with the help of gills and also their bodies reabsorb salt from urine.
Phospholipids have phosphate group heads that are hydrophilic while the fatty acid tails are hydrophobic.
They are able to form cell membrane as they automatically arrange themselves in the required pattern in water because of these properties.To form membranes, these line up next to each other with their heads on the outside of the cell and their tails on the inside. A second layer of phospholipids also forms with heads on the inside of the cell and tails facing away.
In this way a double layer is formed with phosphate group heads on the outside, and fatty acid tails on the inside. This double layer, called a lipid bi-layer, forms the main part of the cell membrane.
