Hemophilia is the result of a defective X chromosome. males have XY chromosomes; females have XX chromosomes. If a man has a defective X chromosome, he has no normal X chromosome to balance it out. Therefore, he is more likely to present hemophilia. However, a hemophiliac man's male children will all be healthy, assuming his partner is not a hemophiliac, because the defective X chromosome was not passed on. All his daughters will be carriers, though, regardless of whether their mother is a hemophiliac.
Explanation:
Locomotion bacteria, protists and fungi The movement for living beings can be the difference between living and dying, some of the bacteria have the ability to move through two mechanisms: movement by flagella and movement by sliding Movement by phalanges: in bacteria, the Flagella are thin and elongated structures that remain attached to the cell by one end. The flagella are made of a protein called flagelin and its shape is helical, for the movement the flagellum has a system called an engine that is at the base and the wall is connected to the membrane. The motor system works driven by protons that move thanks to the action of the proteins of the base of the scourge., The rotation and movement of the scourge are not constant and depend on stimuli. The flagella are arranged differently according to the type of bacteria, there are peritic, lofotrica and polar flagella.

Brief-ish answer:
"Fertilization in plants occurs when pollen grains are transported from anthers to stigma. When ripe pollen from an anther catches on the stigma of the same kind of flower, each pollen grain sends out a small thread-like tube."
Here's a fuller answer:
"</span>Fertilization occurs after pollination, when pollen grains land on the stigma of a flower of the same species. During this time, a series of events take place leading to the formation of seeds. A pollen grain on the stigma develops a tiny tube that runs down the style of the ovary. The pollen tube contains a male gamete which meets the female gamete in the ovule. Fertilization occurs when the two gametes combine and their chromosomes join. The resulting product is a normal complement of chromosomes, with some from either parent flower. The fertilized ovule forms a seed, which consists of a food reservoir and an embryo that later develops into a new plant. In gymnosperms (conifers) male gametes are enclosed in pollen grains and are transmitted by wind or insects to the female reproductive organs. Fertilization in angiosperms (flowering plants) occurs when insects or other animals transport the pollen to the female reproductive organ (pistil).<span>
</span><span>Fertilization is the fusion of gametes to launch the development of a new individual organism. In animals, the process entails the combination of ovum with a sperm, leading to the development of an embryo. Fertilization in plants occurs when haploid gametes meet to create a diploid zygote, which eventually forms an embryo.</span><span>"

Answer:
Separately in Nucleus and cytoplasm,
Simultaneously in the cytoplasm
Explanation:
In eukaryotes transcription and translation occurs separately in the nucleus and cytoplasm respectively. Transcription occurs inside the membrane bound nucleus and the mRNA transcript is transported to the cytoplasm for translation.
In prokaryotes, because prokaryotic cells lack a membrane bound nucleus, transcription and translation occurs simultaneouslyin the cytoplasm. This means that translation of mRNA begins even while the transcription of the transcript is still active.
Explanation:
i think u should ask Google first i don't think my answer is right i don't to mark u wrong please sorry
