Answer:
Stresses such as lack of nutrients, space, competition and water availability.
Explanation:
Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.
Answer:
Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose
Here is the answer but not complete i forgot the ribosome diagram
But I hope it helps
Answer: seen in the explanation.
Explanation:
Patellar reflex is a stretch reflex which tests the Lumber vertebral 2- 4 segments of the spinal cord.
The major event that occurs after Striking of the patellar tendon with a reflex hammer just below the patella includes;
1) It stretches the muscle spindle in the quadriceps muscle.
2) A signal is produced which travels back to the spinal cord and synapses (without interneurons) at the level of Lumber vertebra 3 in the spinal cord, completely independent of higher centres.
3) After the synapse an alpha motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction.
4) Contraction of the quadriceps femoris muscle, coordinated with the relaxation of the antagonistic flexor hamstring muscle causes the leg to kick.
This is a reflex of proprioception which helps maintain balance and posture.
