Humans are produced via sexual reproduction. That gives genetic diversity. You do not get such genetic diversity in case of the parthenogenesis. It is poor mode of reproduction.
As a mammal, a deer would be reproduced internally.
The fruit tree can be asexually reproduced through grafting, budding or sprouting, but the fruit itself would not exist if the tree had not reproduced sexually. The seed within the fruit is the proof of sexual reproduction.
it would not occur at all
Yes, because mating with yourself is a kind of incest. That wouldn't be cloning (/parthenogenesis), as the animal has no mechanism for this. Combining your own sperm and eggs combines defect genes, like incest would. ^^
because humans have no need for it and we would probably be then rooted into the ground
Lets say there are 20 prokaryotes and they don't reproduce. They would die one by one until you had no prokaryotes. If they had reproduced, you would have more than 20 prokaryotes. So what I'm trying to say is that prokaryotes reproduce to keep their race alive. If humans didnt reproduce, in a while there would be no humans at all. It's the same with prokaryotes. Hope this helped.
Most definitly. Asexually reproduced plants are clones of each others so have no genetic variation. Sexually reproduced planst combine the dominant genes from both the partent plants

They cannot. Should the sperm and egg of these two species meet, nothing will happen. Nature does not allow it. Only animals of similar genus - like lions and tigers, or horses and donkeys, can conceive outside their species. Most of the time their offspring is sterile.
Velociraptor reproduced sexually, having a mate. it laid it's eggs in a nest.
vasectomy and tubal lugation explaine how they affect reproduction in humans
Parthenogenesis is a process whereby a single egg can develop without the presence of biologic material (sperm) from a male. In some lower animals parthenogenesis can lead to reproduction naturally, for example, it is a common form of reproduction in flies, ants, lizards, snakes, fish, birds, reptiles, amphibians, honeybees, and crayfish. Eutherians (mammals with a placenta) are not capable of this form of reproduction; therefore parthenogenesis is not known to occur naturally in primates or most other higher order animals. The advantages of parthenogenetic reproduction are that without sex, parthenogenesis takes less energy and allows for more rapid reproduction in the short term. This is great for insects that may want to increase their numbers quickly to inhabit a new territory. In addition, it allows reproduction to occur in some animals when sexual reproduction is impossible; for example, if a female were isolated and unable to find a male with whom to mate. Finally, if a species is already well adapted to its environment, it may not pay to expose the species to the genetic variation brought by sexual reproduction. However, on the flip side, because only one individual's genes are passed on to the offspring, parthenogenesis limits genetic diversity and without diversity, genetic mutations can amplify within a species. Although mammals do not reproduce using parthenogenesis, parthenogenesis can be used to cause an unfertilized human egg to form a ball of cells called a blastocyst from which human stem cell lines can be created. These stem cell lines (called parthenogenetic stem cell lines) have been shown in published research to have the same capacity as an embryonic stem cell line to create, through differentiation, the basic human tissues that lead to all cells in the human body. In addition, researchers have shown that specific human cells created from parthenogenetic stem cell lines, such as liver-like cells, retinal pigment cells, nerve cells or beating heart-like cells may be useful for research and for therapies based on cell implantation. However, the parthenogenetic blastocyst, even if implanted back into the womb of the donor, would not produce a viable fetus so nothing that could become a viable human life is ever destroyed.
No. Humans will never grow fins because we have no use for them. A characteristic will evolve because slight variations (the very beginning of that characteristic) improved the survival chances of an organism so that it survived and reproduced at the expense of others that did not have this variation. So it is possible that if some stone-age humans tried to live an aquatic lifestyle, then you may see things like webbing between the fingers. This is extremely unlikely and is a poor example of evolution, because humans would be far more likely to invent something to fill this need, even stone age humans. I cannot actually think of a single situation where humans having rudimentary fins would lead to some humans surviving and others dying.
If your brain overheats, you instantly die.
Nothing would happen. Humans ARE animals.
it would occur in the north of pensacola
