When a metatarsal bone, a bone connecting the toe to the rest of the foot, is involved, pain will be felt in the upper foot. Metatarsal Bone Spurs-A bone spur in one of the metatarsals often coincides with a presence of arthritis in the area, and both the spur and the arthritis may require treatment.
Haploid organisms such as fungi, yeast, and algae can have complex cell cycles, in which the choice between sexual or asexual reproduction is fluid, and often influenced by the environment. Some organisms, in addition to their usual haploid state, can also exist as diploid for a short time, allowing genetic recombination to occur.
We have mentioned two types of nuclear division: mitosis, where the nucleus divides into two identical nuclei, and meiosis, which results in the production of four nuclei with half the original number of chromosomes of the parent cell.f a haploid cell undergoes mitosis, which is something certain types of plant and fungus do as part of their normal life cycles, the end result is two identical haploid cells (nân). In meiosis, however, you start with a diploid cell that divides twice to produce four haploid cells.
