Write one feature which is common to each of the following terms:a) Autotrophic and heterotrophic nutritionb) Chlorophyll and hemoglobinc) Gills and lungsd) Arteries and veins

a) Autotrophic and heterotrophic nutrition: Both are types of nutrition that organisms use to obtain energy. Autotrophic nutrition involves organisms making their own food (like plants through photosynthesis), while heterotrophic nutrition involves organisms consuming other organisms for food.

b) Chlorophyll and hemoglobin: Both are pigments that play crucial roles in life-sustaining processes. Chlorophyll is involved in photosynthesis in plants, while hemoglobin carries oxygen in the blood of animals.

c) Gills and lungs: Both are respiratory organs that facilitate the exchange of gases. Gills are found in aquatic animals like fish, and lungs are found in terrestrial animals like humans.

d) Arteries and veins: Both are types of blood vessels that transport blood throughout the body. Arteries carry blood away from the heart, while veins carry blood towards the heart.
