Seawater, water that makes up the oceans and seas, covering more than 70 percent of Earth's surface. Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.
The most abundant dissolved ions in seawater are sodium, chloride, magnesium, sulfate and calcium. Its osmolarity is about 1000 mOsm/l.

A hereditary carrier (or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease.
Answer:
Types of Transpiration
There are three different types of transpiration in plants:
Stomatal Transpiration
It is the evaporation of water from the stomata of the plants. Most of the water from the plants is transpired this way. The water near the surface of the leaves changes into vapour and evaporates when the stomata are open.
Lenticular Transpiration
Lenticels are minute openings in the bark of branches and twigs. Evaporation of water from the lenticels of the plants is known as lenticular transpiration.
Lenticels are not present in all the plants. A minimal amount of water is lost through lenticels.
Cuticular Transpiration
It is the evaporation of water from the cuticle of the plants. The cuticle is a waxy covering on the surface of the leaves of the plants. About 5-10% of the water from the leaves is lost through cuticular transpiration. During dry conditions when the stomata are closed, more water is transpired through the cuticles.
They are called a population, because they are the same species living in a given area. The word population means the amount of a certain species living in a certain environment.

Various environmental factors affect the marine ecosystem. These factors include light, oxygen levels, depth of ocean, salinity, density and pH. These factors are varies with depth in the ocean these factors will either support or limit the life processes of the marine organisms.
The region in the depth of ocean up to where light can penetrate is called photic zone which extends from few meters to 150 meters. Photosynthetic organisms such as phytoplankton and about 90% of all marine life lives in this zone.
In the deep ocean the pressure is very high so, organisms have to survive under extreme pressure. In the deep ocean organisms are small and with low metabolic rate.
