Answer:
D. Heart contraction and pulse are connected with one another.
E. Atrial diastole and ventricle diastole.
Explanation:
Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.
In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.
The ciliated simple columnar epithelium is a tissue that would line the uterine tubes and function as a conveyor belt to help move a fertilized egg toward the uterus. The ciliated columnar epithelium transfers mucus and constituents through cilia and is originate in the upper respiratory area the fallopian tubes, the uterus, and principal part of the spinal cord. It is the main objective of contamination for common cold illnesses.
The answer is A. V-shaped trench and B. A bioluminescent fish (apex)
Answer:
1) pathway taken by water
water is absorbed from the soil, through the root hair cells and is transported by the xylem vessel up the stem to the leaf and/or flowers. From the leaf, some water is lost to the atmosphere as vapors escape out through the stoma present in the lower epidermal layer of the leaves.
2) water potential gradient
water potential refers to the concentration of water present. A gradient forms when there is a difference between the concentrations of water in two regions separated by a partially permeable membrane.
Hence, water moving down a water potential gradient means that it goes from a region of high water potential to a region of low water potential.
3) There are tiny openings on the lower side of the leaves called as stomata (plural: stoma) that allow for gaseous exchange to occur. These openings are controlled by guard cells which are open during the day and close during the night.
Hope that answers the question, have a great day!
