Gestation

(Collins, Francis S.). These animals are ones such as mice, rats and rabbits. Losing a few of these animals isn’t as significant as killing off billions of herd animals (that don’t reproduce as quickly) for our food supply. An average rabbit 's gestation period is 28-31 days (Krempels, Dana) in comparison to a cows which is 274 days (Cattle). Rabbits have the capability of reproducing nearly 10 times as fast which goes to show how the loses of their numbers aren’t as significant as those of a…

Men and women are different in many aspects, wether it comes to society, the workforce, or even scientific fact. Due to these reasons, the ways in which both sexes live are different, but this isn’t to be looked at as discrimination against one or the other, but instead to be celebrated. These differences have been around for many years, developed, integrated, and adapted in to ways that suit the modern day. Men and women will always be different from one another as long as time goes on, this is…

Here are some of the common tests and scans for the first trimester: 1. Your first prenatal visit As soon as your…

One of the many animals in the Amazon Rain forest is the Hoatzin. It is such a unique and different animal that you almost have to see to believe that it exists (Billerman). Its outer features are from various types of animals (editors of Britannica encyclopedia). Some of its characteristics are from cuckoos, turkeys and chickens. The hoatzin also gets some of its inner parts from cows, like its digestive system. Because of this, some people call it a “flying cow” but it is not actually a…

mating scream uttered by the female sloth alerting all of the males in the area that she is ready to mate. The males duke it out by hanging from a tree and swatting at each other until one of them gives up. Females have one baby at a time and gestation is anywhere from 5 months for one species of sloth to 11.5 months for another.

Pam is a 30 year old woman who is in her third pregnancy with a BMI of 24 before being pregnant, which is considered normal (Division of Nutrition, Physical Activity, and Obesity, 2015). She has gained 20 pounds throughout the pregnancy and she is 30 weeks pregnant. According to the Nutritional Foundations and Clinical Applications textbook, a woman who has a normal body mass index (BMI) before pregnancy will gain 25-35 pounds in total but only 1 pound per week in the second and third trimester…

it means that that abortion does not inflict pain to the fetus. Yet, there is another side to this argument as there have been anatomical studies that show that the body’s pain network is the spino-thalamic pathway, which is formed by 20 weeks gestation. Dr. Paul Ranalli, a neurologist from the University of Toronto, states, “At 20 weeks the fetal brain has the full complement of brain cells present in adulthood, ready and waiting to receive pain signals from the body, their electrical activity…

Hog Confinements The lies everyone is getting told on how bad hog confinements are, this is really hurting the farmers. They put their lives into raising and taking care of theses hogs.

Most hog farmers families don’t see them unless it weekends or they go with them to work. They spend hours…

Behavior Although mostly terrestrial, Didelphis virginiana also uses arboreal and aquatic locomotion. On the ground, its gait resembles that of primitive mammals [6], which is unsurprising given that opossum-like mammals first appeared over 65 million years ago around the time when the dinosaurs were going extinct [12]. Though the opossum’s arboreal locomotion is aided by the adaptations mentioned earlier, it is still relatively slow and clumsy. However, it is a strong – if slow – swimmer, and…
