The pattern of embryonic cleavage peculiar to a species is determined by two major parameters: 

(1) the amount and distribution of yolk protein within the cytoplasm, which determine where cleavage can occur and the relative sizes of the blastomeres

(2) factors in the egg cytoplasm that influence the angle of the mitotic spindle and the timing of its formation

Which of the following statements is incorrect about patterning of embryonic cleavage?

Following are given some prediction about stress response which ultimately generate ROS;

a) Stress response activates the scavenging mechanism by ROS , these ROS is responsible for activating self-generation  mechanism by using RBOH

b) ROS have a negative effect on plant growth,  development,  and  yield

c) Almost every stress leads to the activation of ROS and its signal transduction

d) ROS indirectly induce acclimation mechanisms

Which of the following is the correct prediction about ROS activated by stress response?
