Dioecy. Gonochorism. Hermaphrodite. v. t. e. Temperature-dependent sex determination ( TSD) is a type of environmental sex determination in which the temperatures experienced during embryonic/larval development determine the sex of the offspring. [ 1] It is observed in reptiles and teleost fish, with some reports of it occurring in species of ...
Manifestations: Normal temperature ranges from 97.7 to 100.0 °F (36.5 to 37.8 °C). Cold infants may cry or appear restless. The neonates' arms and legs maintain a fetal position, lessening their body surface area and reducing heat loss.
Normal human body temperature ( normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [ 8][ 9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation ...
Most have a normal body temperature set point that falls within the range of 36.0 to 37.5 °C (96.8 to 99.5 °F). [13] The main reason for checking body temperature is to solicit any signs of systemic infection or inflammation in the presence of a fever. Fever is considered temperature of 37.8 °C (100.0 °F) or above. [13]

The Apgar score is a quick way for health professionals to evaluate the health of all newborns at 1 and 5 minutes after birth and in response to resuscitation. [ 1] It was originally developed in 1952 by an anesthesiologist at Columbia University, Virginia Apgar, to address the need for a standardized way to evaluate infants shortly after birth ...
Imagine being on a safari in Kenya when you stumble across a herd of elephants grazing in the grass. You see a mom and two young calves, and of course, you stop to watch the little ones.
Development of the human body is the process of growth to maturity. The process begins with fertilization, where an egg released from the ovary of a female is penetrated by a sperm cell from a male. The resulting zygote develops through mitosis and cell differentiation, and the resulting embryo then implants in the uterus, where the embryo ...
