The right answer is an isotonic solution.
An isotonic solution is a system in which the osmotic concentration is the same as the solute concentration of a cell. In this case, the cell does not swell or shrink because there is no gradient of water concentration across the cell membrane.
The water molecules diffuse across the plasma membrane in both directions, and the rate of water diffusion is the same in each direction of this cell without gaining or losing water.

Answer:
1- Temperate rainforest biome
2- Coniferous (boreal) forest biome
3- Desert biome
4- Tundra biome
5- Temperate deciduous forest biome
6- Tropical rainforest biome
Explanation:
The tropical rainforest biome is located near the equatorial region where the amount of sunlight is maximum. As a result of which this area experiences maximum rainfall, that helps in the increasing amount of plants and animal species. This provides all the essential nutrients required by the organisms. Here, in this region, the temperature throughout the year remains high and receives the highest amount of rainfall.
The tundra biome is located in and around the polar region. The temperature in this region remains very cold, supporting a good number of plant and animal species.
The desert biome is located along the 30° latitude in both the hemisphere. The temperature remains relatively very high throughout the year due to the lack of rainfall. The region is very dry. There is significantly less amount of plants in this region.

The genes involved in albinism are not linked. Gene mapping enables the localization of different genes on specific chromosomes.
Gene mapping refers to the genetic techniques used to establish the locations of specific genes on the chromosomes.
Moreover, a karyotype is a preparation of the set of condensed chromosomes in the metaphase stage, which are ordered according to their length.
In this case, it is possible to conclude that the four genes involved in albinism are not linked because they are found on different chromosomes (chromosomes 11, 15, 9 and 5).
Since albinism is passed from parents to offspring in an autosomal recessive inheritance pattern, a person can receive this trait by receiving two copies (one of each parent) for the four mutated genes involved in albinism.

Nondisjunction is the failure of a pair of chromosomes to separate (to disjoin) during cell division (meiosis). When this happens ( in anaphase I of meiosis) two out of the four new daughter cells produced from a parent cell will have an extra copy of one chromosome and the other two daughter cells will end up missing that chromosome.
Most of the time when fertilization involves gametes with an abnormal number of chromosomes, the resulting cell does not survive to produce a new individual. However there are some cases where the individuals survive and such, when they are born end up having a syndrome caused by too many or too few chromosomes. An example is Turners syndrome caused by too few chromosomes (monosomy x) , and Down syndrome caused by too many chromosomes (trisomy 21).
Answer:
Nondisjunction is the failure of a pair of chromosomes to separate during meiosis.
Explanation:
Protein synthesis is an anabolic reaction because these reactions build molecules while catabolic ones break them down. Thanks to this we know that protein synthesis is anabolic.
Explanation:
Anabolism relates to the process in cells where large macromolecules are formed up from miniature ones. In this case here, protein structure uses other proteins and amino acids (proteins' monomers) to make extra proteins, and so that is the accumulation of a large molecule, and accordingly studied anabolism.
Catabolism is the reverse of anabolism. An example would be the separation of proteins in food to amino acids for digestion. In this case, a large particle (a protein) is split down into miniature dispersible molecules (amino acids).
