<span>Because an increase in oxytocin level increases the contractions </span>
Oxytocin can be defined as a hormone that usually acts on organs
of the body which includes the uterus and breast. They can also act as a
chemical messenger in the brain by controlling some important aspect of
reproductive system such as lactation and childbirth. However, the positive feedback
mechanism of oxytocin is that an increase in release of oxytocin will stimulate
more contractions.
Answer:
fills with blood during arousal and causes an erection.
Explanation:
The corpus spongiosum is a mass of tissue present in the under part of the penis (male sexual structure) that is actively responsible for erection of the penis. The corpus spongiosum, in conjunction with the corpus carvernosa works to maintain erection of the penis in males.
During sexual arousal, the corpus spongiosum, which surrounds the urethra (passage for urine and semen) helps keep the urethra open for semen to be released while the carvernosa becomes filled with blood. This constant flow of blood into the carvernosa makes the penis enlarge and assume an erect position.
1) Relying on computers and not going to the field. Sometimes a technical or software fault could lead to a wrong prediction. it could be a new forecaster who does not know the weather patterns and so follows the computer model instead of stepping outside and actually feeling the weather
2) The atmosphere always changes with natural disasters occurring such as pollutants in the air that make forecasting difficult.
3) Most of the times meteorologists base their forecasts on probability. Because of differences in the climate, those temperatures are not the same, so errors occur.
