Answer: Option C.
High-energy waves like UV light or radiation physically damage the DNA
Explanation:
Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.
Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.
The material or substance on which an enzyme acts upon is known as the substrate, they are nothing but reacting molecules and or substances that are able to ultimately be converted to product substances. By the aid of biological enzymes, that lower the energy of activation needed for a chemical reaction to proceed.
Answer: Imagine life without your best friend. Who would you hang out with and talk to about your problems? Life would be so lonely! You rely on your friends for companionship, fun, and support. Animals rely on each other, too. Some have lifelong relationships with other organisms, called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism.
Mutualism: both partners benefit. An example of mutualism is the relationship between the Egyptian plover and the crocodile. In the tropical regions of Africa, the crocodile lies with its mouth open. The plover flies into its mouth and feeds on bits of decaying meat stuck in the crocodile’s teeth. The crocodile does not eat the plover. Instead, he appreciates the dental work. The plover eats a meal and the crocodile gets his teeth cleaned. Coincidentally, the Egyptian plover is also known as the crocodile bird.
Commensalism: only one species benefits while the other is neither helped nor harmed. For example, remora fish are very bony and have a dorsal fin (the fin on the back of fish) that acts like a suction cup. Remora fish use this fin to attach themselves to whales, sharks, or rays and eat the scraps their hosts leave behind. The remora fish gets a meal, while its host gets nothing. Selfish, sure, but neither gets hurt.
Parasitism: One organism (the parasite) gains, while the other (the host) suffers. The deer tick is a parasite. It attaches to a warmblooded animal and feeds on its blood. Ticks need blood at every stage of their life cycle. They also carry Lyme disease, an illness that can cause joint damage, heart complications, and kidney problems. The tick benefits from eating the animal's blood. Unfortunately, the animal suffers from the loss of blood and nutrients and may get sick.
Dehydration is the loss of too much water in our body It can be categorized into three types: isotonic, hypotonic and hypertonic. Isotonic dehydration is the most common, which pertains to equal concentrations of the extracellular and intracellular fluids. In this type of dehydration, about same amount of electrolytes and water are ;pst from the body. Hypertonic dehydration is more serious and a very risky IV fluid to administer. This type of dehydration occurs when more electrolytes are lost than water from the body. So, there must be an intake of a fluid more concentrated in electrolytes so that it will cause the water from inside the cells to be attracted to the extracellular fluid. The last type of dehydration, hypotonic dehydration, is the opposite of hypertonic. This is when more of water is lost than electrolytes. So, the fluid to be administered is less concentrated relative to the fluid inside the cells.
