ANSWER: Hello, I have been pregnant/miscarriage twice this year and with each I had symptoms during implantation. This time I've experienced intense lower pack back and cramping, along with mild headache, though no bleeding/spotting. So, yes there can be symptoms/cues, but not everyone experiences them. Some women don't experience anything until late in the first trimester. I never had 'morning sickness' with my first child. Everyone is different.
Fertilization.
There are a great many animals that have internal fertilization and live in water. Sharks and whales are great examples.
Examples of fruits that can grow without fertilization include bananas, pineapples, and figs. These fruits can reproduce through parthenocarpy, a process where fruit develops without seeds or fertilization occurring.
Examples of power from applied science include depletion of trees and coal. Additional examples of applied science are invitro-fertilization and cloning.
Mostly water animals do external fertilization
The process of preventing fertilization of eggs is called contraception or birth control. Examples of contraception include the birth control pill, Depo Provera injection, the coil and condoms.
A group of plants that depend on animal vectors for fertilization is called zoophytes. These plants rely on animals, such as insects, birds, or bats, to assist in the transfer of pollen from the male reproductive organs to the female reproductive organs, thus enabling fertilization. Examples include many flowering plants and orchids.
Performance on the Job
A color that is not associated with any hue is called achromatic. Examples include black, white, and grey.
Some are one sex part of the time and the other sex part of time. Some have reproductive organs that are far enough removed from each other that self fertilization is difficult. Others that release ova and/or sperm along with many other individuals and fertilization is random. These are just examples there are probably many more variations.
Examples of mitochondria-associated processes include cellular respiration, ATP production, apoptosis regulation, and calcium signaling within cells.
Examples of vegetables that undergo sexual reproduction include tomatoes, cucumbers, and peppers. These plants produce flowers that contain both male and female reproductive structures for pollination and fertilization to occur, leading to seed production.
