It should be true due to adaptations. when a bird doesn’t stay for winter weather so it adapts by migrating to the south during the cold weather
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
It creates high blood pressure because your body is trying to remove it the best it can and decreased blood flow because your body does not want that blood going bad of that makes sense.
Hey there,
Your question states: Explain why it makes sense that the levels of estrogen and progesterone are low in the blood of a female during menstruation.I'm a guy, but I just happen know this information.The reason why the levels of estrogen and progesterone are low in the blood of a female during menstruation is to basically produce (FSH) or follicle stimulating hormone. We need to remember that menstruation is part of the menstrual cycle, which to would help a women/teen to handle/establish a well and healthy pregnancy, (if that makes sense). The average cycle would basically be i think about like 25-28 days. And one thing to remember is that when there is a <span>ripening egg,this causes estrogen levels to rise. This would be the reason why its low.
Hope this helps</span>
