Hello There!
The reproductive cells in females are called eggs. The functions of the female reproductive stem are to produce sex hormones, to provide eggs and to provide a nourishing environment in which a fertilized egg is developed into a baby.
OVARIES The reproductive glands in which eggs are produced are called ovaries.
FALLOPIAN TUBES These are passageways that carry eggs way from the ovaries.
UTERUS This is a solid muscular pear shaped organ. A fertilized egg can develop and grow in the uterus.
VAGINA This is known as the birth canal. This is a hollow muscular passage that leads from the uterus to the outside of the body.
Answer:
This electrical signal start in the sinoatrial node generates an electrical impulse. From this, the signal passes through the atrioventricular node, which stops the signal for a brief moment and sends it through the muscle fibers of the ventricles, stimulating its contraction.
Explanation:
The electrical impulses generated by the myocardium stimulate the heartbeat. This electrical signal originates in the sinoatrial node located in the upper part of the right atrium. When the sinoatrial node generates an electrical impulse, it stimulates the contraction of the atria. From this, the signal passes through the atrioventricular node, which stops the signal for a brief moment and sends it through the muscle fibers of the ventricles, stimulating its contraction.
Answer:
a) Negative correlation
Explanation:
Negative correlation is a term which basically explains a relationship between to variables in which increase in one variable causes a decrease in the other variable and vice versa. As in the given scenario, the more frequently the teeths are brushed ( variable is increasing ) the less likely is the chance to develop cavities (variable is decreasing)
Hence a)negative correlation is the right answer.
