Explanation:
Avascular necrosis is basically the death of bone tissue due to a lack of blood supply. Also known as osteonecrosis, it can lead to tiny breaks in the bone and the bone's eventual collapse. A broken bone or dislocated joint can interrupt the blood flow to a section of bone.
HOPE IT SATISFIES YOUR ANSWER!!
Explanation:
during photosynthesis, carbon dioxide and water are taken in by the autotrophs and energy is produced in the form of glucose, which is stored in plants in the form of another moleculecalled as sucrose. Know that oxygen is just a byproduct thus formed after photosynthesis.
during aerobic repiration oxygen and glucose are consumed to give energy as in ATP, adenosine triphosphate, and water. and carbon dioxide is a waste product
Correct answer - Vitamins.
Why? - Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C).
Answer:
The correct answer is d.non-vascular plants with a dominant gametophyte.
Explanation:
Bryophytes are non-vascular plants that present a reduced and not constantly present sporophyte, also their gametophyte is very dominant and is, basically, the whole structure. Their sporophyte only grows when they're reproducing and they disappear when the spores are spread.
Answer:
The correct answer will be option A.
Explanation:
The atrioventricular valve is one of the four valves present in the heart the function of which is to stop the back flow of the blood from the ventricles to the atrium.
These valve opens and closes in response to the change in the pressure of the blood in atrium and ventricles. The valve opens when blood is pumped form the atrium to ventricles which causes the papillary muscles to relax while the valve closes when the ventricles push the blood to the arteries. This causes the papillary muscle to contract which causes the chordate tendineae to create tension ad close the valve.
Thus, option A is the correct answer.
