During meiosis.(:
Sexual reproduction involves the fertilization by two separate hosts , male and female, except in the case of asexual creatures, where the two are contained in one. Cell division occurs after fertilisation, when the two separate cells join, they start to divide.
Usually at the age of two, however, they will show heat cycles before then. Most farmers start breeding females timed to have the first calf at the age of two and most bulls depending on size can start to breed around 2.
No- this is because bacteria can reproduce in minutes due to asexual reproduction.
A bumblebee lives no more than a year. The queen bumblebees are produced at the end of a season, then they overwinter and start a new colony the next season. The workers just survive for the season.
You need to find a chladagram that goes far enough to include where vertebrates an invertebrate seperate. It will need to run up through amphibians and include arthopods. A couple of items would be they both lay eggs, undergo metamorphism in their life cycles and are poikiotherms (body temperature is environmentally controlled, commonly known as cold blooded). (or that they both start with F)
but the adaptations are gametes ( cells like the sperm and the egg which have to join together) and sexual organsIt causes genetic variation and allows for better survivability.
Yes. All organisms that are produced by sexual reproduction start out as a single cell called a zygote. The zygote is the cell that results from the fertilization of the egg by the sperm.
There are two types of monera reproduction. One kind is Binary Fission, and the other is sexual reproduction. In the Binary Fission process, a monera splits its DNA into two. Then the DNA moves to opposite ends. After that, the cell walls start to break, which is called "cell wall synthesis." For the sexual reproduction, two moneras attach and make a new monera.
This would be the start of twins. They would be identical twins because they come from the same egg.
Tradition - once you start with sex it's tough to stop (impossible in fact).
Asexual Reproduction is another method of species reproduction much like, sexual reproduction. The exception is that sexual reproduction typically requires another organism of the opposite gender to fertilize the another organism of the same species in order to start the procreation process. As opposed to Asexual reproduction, usually genders do not exist and the organism and fertilize itself and procreate without another organism being present.
Fiesta dinnerware was founded in 1927 by Homer Laughlin. It was introduced to the public in 1936, and produced through 1972 when it was retired. Fiestaware was reintroduced through reproduction in 1985, and continues to be produced today.
Guinea pigs reproduce via sexual reproduction. This means that both a male and female guinea pig is needed to produce a guinea pig fetus. Much like humans, both a sperm and ova are required to start the life of a new creature.
the peacock butterflys reproduction is during the following spring in which they start to mate.

No, not all organisms start out as embryos. Embryos are typically seen in higher animals that undergo sexual reproduction, where a fertilized egg develops into an organism. Organisms like bacteria and protists reproduce asexually and do not have an embryonic stage in their life cycle.
Budding is a characteristic of asexual reproduction, not sexual reproduction.
