Isotonic solutions is the term used when the concentrations of solutes inside and outside a cell are in equilibrium.
Explanation:
The isotonic solution is one which have same osmotic pressure on either side of the semi-permeable membrane.
In the isotonic solution there will be free movement of only water molecules and not solutes.
isotonic solution is the solution when two solutions have equal solute concentration.
The concentration of the solution will be in equilibrium.
The answer is '<span>triploid cell'.

This occurs when two sperm nuclei reach the interior of a female gametophyte, where one sperm will fertilise the egg cell to form a zygote, whereas the other usually fuses with the binucleate central cell, forming a primary endosperm cell, effectively constituting an organism separate from the growing embryo. Approximately 70% of angiosperm species have polyploid endosperm cells which are typically triploid (containing three sets of chromosomes), but can vary widely from diploid(2n) to 15n.
Exothermic and it does follow the law of conservation of energy.
Answer:
Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.
