What is the function of the upper and lower chambers of the heart?
the upper chambers collects blood before sending it into the ventricles. the ventricles which are also known as the lower chambers pump blood away from the heart.right and left atrium. they collect and hold blood before sending them into the ventricles. the ventricles pump the blood away from the heart.
Which has more stomata the upper or lower epidermis?
Lower epidermis of leaves being away from direct sunlight have more stomata per unit area to minimize exessive traspiration.
Why are some types of glasses called bifocals?
Because they are bifocals. Bi=two. The lower half lets you see things Close, the upper half lets you see things farther away. Like two glasses in one.
Why do your upper cupboards lower counters pull away from the wall in the winter?
Because heat expands and cold contracts. Like putting ice on a swollen ankle.....
Why is stomata not on the top of the leaf?
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.
Why does a cow have no upper teeth?
Because, through the process of evolution, ruminants have had no need for upper teeth. Cows also do not have flexible lips like horses do, so upper teeth are not needed. Instead they use their powerful tongues to grab and help rip forage from their stems with their lower incisors. Their lower incisors are also angled outwards (away from the mouth) to help with shearing and tearing off plants to eat.
What side of a leaf are stomata located?
The lower surface of the leaf has the stomata. You can see the reason for this if you cut a leaf in half from upper side to lower side. The upper portion of the leaf consists of tightly packed cells that are full of chloroplasts for taking in light. The lower half of the leaf is made up of loosely arranged cells. This allows room for air to enter the lower part of the leaf through the stomata and contribute carbon dioxide and take away oxygen. The upper surface of the leaf is covered by the cuticle which prevents dehydration, as such the stomata cannot be located or function on the upper surface
What are the 6 major structural differences between the anatomical plan of the upper and lower limbs?
The Pelvic Girdle is a complete circle while the Pectoral Girdle is notThe Pelvic Girdle does not support the weight of the body, rather it is the attachment site for many muscles that move the upper limbs. (the collar bone's main function is to keep the shoulder joint away from the midline of the body allowing greater it greater mobility). In contrast, the pelvic girdle receives the weight of the upper body from the axial skeleton, (the spine) and supports it.They both employ hinge joints in the middle, "the ginglymus of the upper extremities and the tibiofemoral joints of the lower extremities"They both have an interosseous membrane separating them. (This keeps them at a fixed distance from each other. It only allows slight movements between them.)The femur has a landmark called the "fovea" through which a tiny ligament connects it to the acetabulum. The humerous does not have this.the most commonly fractured bone of the upper extremities is the upper arm, (humerous), while the most commonly fractured bone(s) of the lower extremities is the lower leg (tibia and fibula,) (the crural region).lower extremity has a large sesamoid bone called the patella, upper extremities do not.the distal ends of the ulna, radius, tibia, and fibula, are called, the styloid processes and the lateral and medial malleolus. These landmarks help to stabilize the condyloid joints of the wrists and ankles.there's probably more, but this is all I can think of.
How can astronomers determine whether a star is moving towards or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.
