Answer: B) energy released from exergonic reactions.
Explanation:
Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).
Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.
The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
Answer:
By the same token, any random change in a gene's DNA is likely to result in a protein that does not function normally or may not function at all. Such mutations are likely to be harmful. Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes
Answer:
Beautiful Huntresses: Scientists Explain Why Mantises Evolved To Resemble Orchids : The Two-Way Typically, when insect females evolve to become larger than males, it's in order to produce more offspring. But female orchid mantises evolved to look like flowers for a sinister reason: to hunt prey.
Answer;
-Chitin is a structural carbohydrate that forms their exoskeleton
Explanation;
-Chitin is the main component in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi.
-It is a linear long chain polymer consisting of repeated units of N-acetyl-glucosamine.
-The main function of the chitin-containing exoskeleton is to keep the inner soft tissue safe from any sort of injury and also prevents the delicate tissues from drying (acts as a water tight barrier against dehydration).
Answer:
8900 CFU/mL
Explanation:
Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.
UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.
Calculation
Colonies * Dilution = CFU/mL
89 * (100/ 1 mL) = CFU/mL
8900 CFU/mL
