<span>The answer is a) mitosis, meiosis. Body cells may produce additional body cells by means of mitosis. Organisms that reproduce sexually produce gametes by means of the process of meiosis. Mitosis is a process which results in two identical cells being produced through division, whereas meiosis results in the splitting of a cell to create two genetically different daughter cells. </span>
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.
Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.
The correct answer is the extensor digitorum longus and fibularis tertius.
The pretibial muscles include the anterior tibialis, extensor digitorum longus, extensor hallucis longus, and peroneus tertius. As a group they are active during the swing phase and the heel-strike to foot-flat phase of gait. Fibularis is often considered as part of the extensor digitorum longus muscle.
