Correct answer: C). Evolution by natural selection, Galapagos finches  

Charles Darwin gave the theory of natural selection in the year 1835 when he visits Galapagos Islands.

There he found several species of finches are adapted to different environmental niches. They have a different shape of the beak, food source they eat and the way they captured the food.

He observes that species vary from island to island, and based on these observations he gave the theory of natural selection.

joja [24]

Answer:

Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.

Explanation:

Since the four proteins used p16,  p18,  p21, and  p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.

Hope that answers the question, have a great day!

Economic importance of tilapia fish
dezoksy [38]

Answer:

Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.

Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.
