Answer:
C. Similar body shape in dolphins (mammals) and fish
Explanation:
- Convergent evolution refers to the development of similar organs with respect to shape, size or function in two different species without an ancestral relationship.
- Convergent evolution produces analogous structures i.e. organs that are structurally and functionally similar but come from different ancestries.
There are choices for this question namely:
1 Cesarean section
2 Vaginal delivery with forceps extraction
3 Vaginal delivery with vacuum extraction

The correct answer is "cesarean section". In cesarean section, we are preventing the vertical transfer of the virus from the mother to the baby by bypassing the vaginal mucosa (which has secretions, potentially with high viral load). Fetal scalp electrode, on the other hand, is not a method of delivery.
Answer:The oxygen-rich blood from your lungs is carried to the left side of the heart through the pulmonary veins. The heart pumps the blood to the rest of the body, where oxygen in the red blood cells moves from blood vessels into your cells. Your cells use oxygen to make energy so your body can work.
They both can be found in the same food chain, but they aren't directly related. A hawk is a tertiary consumer (top of the food chain) and grass is a producer (bottom of the food chain). The hawks survival depends on grass:
Grass feeds on nutrients from the ground → insects eat grass and flowes → bigger insects eat the smaller insects → field rats eat the insects → hawks eat the field rats.
