Answer:
DNA that contains genes from more than one organism is called "Recombinant DNA".
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
The right option is; a. fatty substances called lipids inside the cell
Among other changes caused by cell aging, there is an increase in pigments and fatty substances called lipids inside the cell.
Aging occurs in the body's cells, tissues, and organs and it therefore affects the functioning of all body systems. Cell aging makes cells sizes to increase and reduces their ability to reproduce. It causes an increase in pigments and fatty substances (lipids) inside the cell. This makes the cells to be inactive or to function abnormally. Aging also causes the accumulation of waste products in tissues.
Answer:
a) B b) D c) A
Explanation:
Alleles exhibit dominance over each other leading to the dominant one being express and the recessive one not expressed. Alleles are variants (different) genes that codes for a specific trait.
At Anaphase 1 homologous chromosomes separate leading to each being pulled to the opposite pole and the sister chromatids remain together while the homologs experience segregation.
Dominant trait is the one that is expressed. It usually exercise dominance over recessive trait until it is removed from the recessive trait and replaced with another recessive gene before it is expressed.
