Biology

A:

The pattern of base pairs in the DNA double helix encodes the instructions for building the proteins necessary to construct an entire organism. DNA, or deoxyribonucleic acid, is found within most cells of an organism, and most organisms have their own unique DNA code. One exception to this is cloned organisms, which have the same exact DNA code as their parents do.

  • How do living things use lipids?

    Q: How do living things use lipids?

    A: Lipids, or fats, are used in living things in a wide variety of different ways, including energy storage and insulation. There are other beneficial properties that lipids can be used for, however, such as digestion and helping provide structure for certain parts of the structure of an organism's cells. In some living things, lipids are even part of the process by which hormones are formed in the body.

  • Why are decomposers important?

    Q: Why are decomposers important?

    A: Decomposers are important because they are crucial for the proper functioning of ecosystems. They recycle the minerals found in dead plants and animals back into the food chain. Ecosystems do not waste energy or materials, and as such, the decomposers capitalize on any remaining energy in a dead organism and make the minerals available to the entire biome.

  • What happens to excess glucose?

    Q: What happens to excess glucose?

    A: The human body has several mechanisms to store or eliminate excess glucose from the blood. Glucose can be converted into a larger molecule called glycogen that is typically stored in the liver and muscles. When the body needs glucose, glycogen is broken down to provide an energy source.

  • How do animals adapt to the rainforest?

    Q: How do animals adapt to the rainforest?

    A: Many animals have adapted to the rainforest by adopting arboreal, or tree-dwelling, lifestyles. For example, chimpanzees have incredibly strong arms and hands, which help them to climb through the many branches and vines in the rainforest understory, according to The Guardian. In addition to their impressive strength, chimpanzees possess very long and flexible arms, which also help them to climb skillfully through the trees.

  • How do fungi obtain food?

    Q: How do fungi obtain food?

    A: Microbe World indicates that fungi absorb food from their immediate surroundings directly through their cell walls unlike animals, which eat food, and plants, which produce their own food through the process of photosynthesis. Kew Gardens adds that fungi function like an inside-out version of an animal's stomach. Instead of eating food and digesting it internally, fungi first dissolve food into simpler nutrients and then absorb the food after they digest it.
