- Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. In the two figures, a wild-type plant and a plant with a atg5 knockout, which prevents autophagy within the cell, are compared. The first figure shows the number of peroxisomes per micrograph image taken of the plant's leaves. The bottom figure shows a comparison of 3-week seedlings of the wild-type plant and the atg5 plant at normal CO2 levels (360 ppm) and elevated CO2 (2000 ppm) Which of the following are true. Question 20 options: the atg5 knockout plants are more able to deal with photorespiration the atg5 knockout plants are less able to deal with photorespiration the inability to recycle peroxisomes through autophagy impairs a plants ability to deal with photorespiration Elevated CO2 overcomes the photorespiration impairment in atg5 plants Elevated CO2 overcomes the photorespiration impairment in wild-type plantsarrow_forwardDraw spicules.

By conventional light microscopy, it is not possible to reliably differentiate WBC from immature germ cells in semen. For clinical purposes, the peroxidase method is ideally suited to detect granulocytes. the presence of an excessive number of spermatogenic cells suggests pathology at the level of the seminiferous epithelium. leukocytospermia may be associated with infection or inflammation of the accessory glands and hydrogen peroxide secreted by peroxidase-positive WBC has unfavorable effects on sperm cell types present clinical implication based on the scenario spermatozoa, few UT and spermatogenic cells, WBC spermatogenic cells WBCarrow_forward
