B
The insulin is made entirely by man but it is technically a organic compound still
If there is no reason to change (constant climate), then change won't occur. For example, a desert is basically always dry and hot with sand and few clouds. If a creature is fit for the climate, it will continue to exist until a severe enough climate change. For a real world example, in pre-industrial Europe, the birch trees were white. This permitted white moths to survive and not get eaten by the owls that hunt them, until the industrial revolution. Ash got on the birch trees, changing the color of the trees to a darker black. The white moths stood out, and therefore got eaten, permitting the black variant of the moths to thrive, where they were close to complete eradication before the revolution.
Answer:
they are not getting enough sunlight to begin with the growth tends to become weak
Explanation:
The light-harvesting complexes of a chloroplast are located in the thylakoid membrane.
The enzymes of the calvin cycle reactions are located in the stroma.
Chloroplast, found in plant cells and some protists such as algae and cyanobacteria, is a cell organelle known as a plastid. Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane.
The enzymes required during the calvin cyle reaction are present in the stroma while, thylakoid System is the internal membrane system consisting of flattened sac-like membrane structures called thylakoids where light energy is converted into chemical energy. Thylakoids contain the light-harvesting complex, including the electron transport chains used in photosynthesis and pigments like chlorophyll and carotenoids.
