I think the enzyme photolyase is activated by light and can repair thymine dimers caused by UV radiation. Exposure to UV radiation is the main factor that causes skin cells to become cancer cells. These enzymes are involved in the repair of ultraviolet light-induced DNA damage when activated by light absorption.
Answer:
organisms that can't make their own food are known as heterotrophs
<h2>EXPLANATION:</h2>
<h3>Modern monoculture requires vast amounts of rain for irrigating crops as moisture retention is limited in the soil. A lack of topsoil also increases rain runoff. To achieve this vast amount of extra water it means draining from lakes, rivers, and reservoirs, which is exhausting natural resources and aquatic ecosystems.</h3>
Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body, which is the part of the fungus that produces spores (Figure below
