Answer:
The correct option is A. they evolved from land mammals.
Explanation:
Evolution can be described as a process through which organisms in a species change over a period of time due to the natural selection of the environment. Those organisms that have many similarities in their functions or structures are considered closer to one another and have the same common ancestors.
The properties mentioned in the question about cetaceans resembles the properties of land mammals. For example, cetaceans lack gills and breathe air. Land mammals also do not have gills and need to respire for living. The cetaceans have fin bones which are similar to the limb bones in the land mammals. Hence, these observations show that cetaceas have evolved from land mammals.
Answer:
El calentamiento global causa que el nivel del mar se eleve, debido a que el hielo en las plataformas continentales se derrite y que el agua del océano se expande al calentarse.
Roughly 15 times more ATP can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysis alone.
<h3>
What is Glycolysis?</h3>
- The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
- A series of ten enzyme-catalyzed processes make up glycolysis. the binding energy of carbs is captured. One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid).
- Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route.
- In fact, the events that makeup glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, likewise in the absence of enzymes, and are catalyzed by metal.

Answer:
love of water
Explanation:
HYDROPHILIC is a term used for substances that are WATER-LOVING in nature. As the name implies, hydro-meaning water and philia- meaning love, it means the love of water. Substances that are hydrophilic tend to be attracted towards water molecules and are readily dissolved by it. For example, sugar molecules are hydrophilic, hence, attract and dissolve in water.
On the other hand, hydrophobic means water-fearing i.e substances under this category repel water. Examples are some fat molecules.
