4. A recent study looked at the effects of increased CO2 concentration on the rate of photosynthesis in wheat during the growing season (from beginning of February to the end of April). The rate of photosynthesis was measured as the rate of CO2 uptake. The control plants were grown at normal CO2 concentration while the test plants were grown at an elevated CO2 concentration. Rate of photosynthesis / mol m²d-¹ 1.25 1.00 0.75 0.50 0.25 0.00 Feb 12 Feb 24 Mar 3 16 Mar Mar 30 Apr 9 Apr 15 Sampling dates Apr 28 a. Describe the pattern of CO2 uptake in the control plants Key: Control CO₂ Elevated CO₂ b. Outline the effect of increased carbon dioxide concentration on the rate of photosynthesis c. Discuss other factors (besides CO2) concentration might impact the rate of photosynthesis

ngs. QUESTION 25 What is the difference between ballistic and proprioceptive neuromuscular facilitation (PNF)? Ballistic stretching involves moving quickly, bouncing, or using momentum to produce a stretch. This type of stretch is often viewed as necessary for sport movements and should be reserved for coaching and conditioning athletes and not used in general physical education. An example would be bouncing down repeatedly to touch the toes. Proprioceptive Neuromuscular Facilitation (PNF) is a static stretch using combinations of active and passive stretching techniques. This specialized static stretch uses a contraction-relaxation combination of movements, taking advantage of reflexes and neuromuscular principles to relax the muscles being stretched. Proprioceptive Neuromuscular Facilitation (PNF) involves moving quickly, bouncing, or using momentum to produce a stretch. This type of stretch is often viewed as necessary for sport movements and should be reserved for coaching and…

Fil in the blanks 1. A resting muscle fiber or neuron has an internal charge that is A. positive, B. negative, or C. neutral compared to the extracellular environment. This resting membrane charge is maintained by the A. calcium ion channels, B. sodium voltage gates, C. potassium voltage gates, or D. sodium/potassium pumps? . When a muscle fiber is at resting membrane potential there is a(an) "higher", "equal", OR "lower" concentration of sodium inside the cell compared to outside the cell and a(an) "higher", "lower", OR "equal" concentration of potassium inside the cell compared to outside.
