- Changes in the position of women. More women go out to get jobs instead of being housewives or having children
- Being financially stable
- Adoption, no need to give birth
- Changes in attitudes towards abortion
- Secularisation
- Better healthcare so babies or children don't die after birth. Infant Mortality Rate in 2007 was 5 deaths per 1,000 in the UK.

Rabbits typically give birth every 30 days, but this can vary depending on factors like age, health, diet, and environmental conditions. These factors can influence the reproductive frequency of rabbits.
Several factors can influence teratogenicity, which is the ability of a substance to cause birth defects. These factors include the timing of exposure during pregnancy, with the embryo being most vulnerable during the organogenesis stage. The dose and duration of exposure also play a significant role, with higher doses and longer exposure periods increasing the risk of birth defects. Additionally, genetic susceptibility and maternal factors such as age, nutrition, and overall health can impact the likelihood of teratogenic effects.
Birth rate (i) Improvement in health and medical facilities help in increase of birth rate.(ii) Decrease in death rate.Death rate(i) When birth rate decreases death rate increases.
Animals wake up from hibernation in the spring. They also give birth to their young. Even I, a 6th grader, knows that.
The vascular system in plants is analogous to the circulatory system in animals. Both systems are responsible for the transportation of fluids and nutrients throughout the organism. In plants, the vascular system consists of xylem and phloem, while in animals, the circulatory system includes the heart, blood vessels, and blood.
Plants do not give birth in the way animals do, as they reproduce through processes like seeds, spores, or vegetative reproduction. Many plants produce flowers that contain reproductive organs, leading to the formation of seeds after fertilization. These seeds can then grow into new plants, continuing the life cycle. In some cases, plants can also reproduce asexually by sending out runners or producing bulbs.
Cows and sheep can give birth at any time of day or night, as their birthing process is not strictly tied to light conditions. However, many animals tend to prefer giving birth during the night or early morning, possibly for safety reasons from predators. Environmental factors, health, and individual circumstances can also influence the timing of their births.
All animals give birth. Animals that give live births, like human, are called mammals.
A live birth is when the animals were born alive, while non live births are where the animals died in utero (before they were born) or during birth.
Polyploidy in animals is rare and often detrimental, leading to abnormalities and sterility. In plants, polyploidy can lead to increased size, vigor, and sometimes new traits due to duplicated genes. In humans, polyploidy is usually not compatible with life and results in miscarriages or birth defects.
Yes, some animals are capable of asexual reproduction, where offspring are produced without fertilization. Examples include certain species of fish, reptiles, and insects. This process is known as parthenogenesis.
