Answer:
Rr x rr
Explanation:
Let's say
RR is a tall plant.
Rr is tall
& rr is a small plant
The only genotypes you can get to make two tall and two short is if you use a hetero pair and a same ressesive (rr) genes.
It is a mode of asexual reproduction in single-celled eukaryotic micro organisms
It usually occurs in archaea bacteria, fungi , amoeba etc....
Answer;
Antibodies.
The human immune system fights infection by releasing antibodies.
Explanation;
The immune system acts to defend the body against pathogens such as viruses, bacteria and fungi that may cause a disease.
It does so using various types of mechanism, one is by the production of antibodies.
Antibodies are proteins that are produced by the B-cell and are used by the immune system to identify and neutralize pathogens.
These antibodies also activates proteins known as complements which assist in the killing of bacteria, viruses and the infected cells.
Current evidence suggests that eukaryotes represent one or more endosymbiotic events in which the host cell was: <u>mitochondrial genomes</u>
What is mitochondrial genomes?
The DNA found in mitochondria, which are cellular organelles found in eukaryotic cells that transform chemical energy from food into a form that cells can utilise, such as adenosine triphosphate, is known as mitochondrial DNA (mtDNA or mDNA)](ATP). Only a small amount of the DNA in a eukaryotic cell is contained in the mitochondria; the majority of the DNA is found in the cell nucleus and, in plants and algae, also in plastids like chloroplasts.
The first large portion of the human genome to be sequenced was mitochondrial DNA.
According to this sequencing, the human mtDNA contains 16,569 base pairs and codes for 13 proteins.
Animal mtDNA serves as a cornerstone of phylogenetics and evolutionary biology because it evolves more quickly than nuclear genetic markers .
