Answer:
Electromagnatic waves.
Explanation:
The energy from the sun is transferred to the earth surface in the form of heat and light. This done through radiation and convection methods heat from the sun is transported to the earth surface through radiation and convection techniques while the light is being transferred.
The term ‘Crossing over’ was used by Morgan and Cattell. It is a process in which there is exchange of chromosome segments between non-sister chromatids of a homologous chromosomes. It occurs during pachytene stage of prophase I of meiosis cell division.
Significance of crossing over:
- Crossing over provides genetic variation in all sexually reproducing organisms.
- It creates new combination of genes or genetic recombination and produces hybrids.
The process by through which the instructions that are present in a DNA is transformed into proteins is called gene expression.
The term is related to to the total number of genes that are inherited from the parents in such a way that a gene contains many information related to the building of proteins and hormones that are necessary for the human growth.
<u>Explanation:</u>
The term Gene expression refers to the transfer of the DNA instructions into proteins. It is the main process that helps a human body responding to the varying environment. It is the main factor that controls and regulates the amount proteins production. The steps transcription and translation is involved in the protein production process
The traits from the parents of an individual like blood group type, color of eye are passed to their children. These are passed through genes. These also passes some diseases also. A gene contains information related to the amount of hormones and proteins to be produced which is done by the gene expression.
