Answer;
ATP is needed to relax the muscles;

Muscles require more energy even if they are not very active in the moment because ATP or energy is needed for their relaxation.

Explanation;
Relaxation of muscles takes place when the stimulation of nerves stops. Calcium is then taken back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. ATP is involved in displacing actin from myosin head. Therefore; ATP is required for muscle relaxation.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).

marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

Observed(o) Expected(e) (o-e) $(o-e)^2$ $(o-e)^2/e$

Green-melon plant 53 47 6 36 0.766

Yellow-melon plant 41 47 -6 36 0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.
