Salts,mostly potassium and sodium are known as electrolytes and the body needs them in very specific amounts for proper function. Any significant imbalance of these levels can even be fatal if not corrected quickly.
The normal level of sodium in the body is 135 - 145 mmol/l in the blood while for potassium it's 3.5 to 5.0 mmol /l.
Loss of salts e.g. due to sweating may reduce these levels and so drinking plain water may replenish fluid loss but since plain water has no salts, the salt deficit remains and is in fact aggravated by the increase of plain fluid.
But drinking fluid that has electrolytes both replaces lost fluids and and at the same replenishes lost salts keeping the body functioning well .
The primary role of endocrine system include :
It secretes chemical messengers called hormones directly into the blood stream.
These hormones control and regulate almost every bodily functions such as;
Endocrine system is a network of glands called endocrine glands that are present throughout the body.

Which process is mostly responsible for warming the soil in Kumar's model?
1. Conduction between the lamp and the soil causes the soil to warm.
2. Convection currents between the lamp and the soil cause the soil to warm.
3. Expansion of particles in the soil causes the soil to warm.
4. Radiation from the lamp reaches the soil and causes the soil to warm.
Answer:
Radiation from the lamp reaches the soil and causes the soil to warm.
The alternation of generations inthe life cycle of a plant includes the diploid and haploid multicellularstages. diploid and haploid are copies of the chromosomes. The spores in theplant is unicellular and when they start dividing through mitosis, it producesidentical cells. These identical cells are all haploid. Haploid stages containone set of chromosome from either of the parent. These identical cells create amulticellular system called the gametophytes. A gametophyte is the haploid multicellularstage in the life cycle of a plant. The gametophyte makes the gametes. These gametesare responsible for sexual fertilization. It takes place when a sperm (malegametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploidzygote. Diploid stages contain one set of chromosome from eachparent. This is where the sporophyte comes in. A sporophyte is the diploidmulticellular stage in the life cycle of the plant. It now contains the twosets of chromosomes from each parent.

Explanation:
Flatworms, roundworms, and segmented worms are all invertebrates. Some species of each type of worm are free-living, meaning they are not dependent on another organism.Some are parasitic.
Flatworms belong to phylum Platyhelminthes. They do not have a coelom, respiratory system or a circulatory system.Tapeworms flukes are examples of flatworms.
Roundworms are part of the phylum Nematoda. They are bilaterally symmetrical invertebrates.They have a psuedocoelom. Ascaris lumbricodes is the most common human parasite.
Segmented worms are the most complex animals of these three invertebrates. They are placed in Annelida. Segmented worms have a true coelom, a circulatory system and a digestive system.An earthworm is a segmented worm.
Although tapeworms have segmented bodies, they do not belong to the phylum Annelida due to key biological differences. The segments in tapeworms are reproductive and not involved in locomotion or digestion, unlike in Annelids, and their nervous systems are structurally different.
The body of a tapeworm is indeed segmented, but it does not belong to the phylum Annelida because there are key differences in their biological make-up. Annelids, such as earthworms, have bodies made up of similarly structured segments with a central nervous system. Moreover, these segments have the potential to function independently.
On the contrary, tapeworms, which belong to the phylum Platyhelminthes, while they have segmented bodies, their segments don't have an independent functional capacity. In tapeworms, these 'proglottids' are reproductive in nature and not involved in locomotion or digestion like the segments in Annelids. Additionally, their nervous systems are structurally different from that of the Annelida.
