Dominant traits are the most likely traits, although recessive traits are still possible to pass down, just less likely.
Allowing livestock to overgraze a region leads to desertification of land
Explanation:
Desertification is the conversion of a once fertile vegetative land to a barren land due to environmental changes. Many human activities and practices are often the cause of desertification of fertile lands.
Overgrazing plays a major role in desertification of lands. When huge number of farm animals is made to graze over vast lands, the entire vegetative cover will be lost.
When there is less protective vegetative cover, then the land becomes dry and barren allowing very less infiltration of ground water which reduces moisture content of the soil. This finally results in land becoming dry and deserted and the precipitation also becomes less. All these conditions recycle and reduce the vegetative growth.
Unsustainable agricultural practices like growing heavily or intensive farming or removing plants in a region also causes desertification, but land use by overgrazing contributes more to desertification.
The catecholamines is the stress related hormone that newborns needs in their bloodstream to avoid breathing problems. A catecholamine is a monoamine which is an organic compound that has a catechol and a side chain amine and is consequent from the amino acid tyrosine which is consequent from the dietary sources as well as fusion from phenylalanine. The catecholamine is water soluble and are 50 percent certain to plasma proteins in transmission.
Answer:
nucleic acids.
Explanation:
The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.
Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.
