What did Darwin notice about life on the Galápagos Islands?

Biology

Because of the isolation of Galapagos, the life forms that had somehow reached the island, such as the lizard and other such creatures, had evolved differently over time compared to their cousins on the mainland. Things like a bird that was usually able to fly no longer had long wings spans or the ability to fly on the island, the large lizards on the island were used to eating sea-vegetation and often swam right into the ocean using their long tails to swim. And so forth.

Darwin found that all the plant life and animals on the island developed from isolation.  Each of these species were also different form the other species on the islands surrounding the Galapagos islands.  Darwin could only explain these characteristics through a gradual transformation of the various species.

Which of the following statements is the most correct regarding homeostatic imbalance? A. It is considered the cause of most dis
AfilCa [17]

Answer:  C. Positive feedback mechanisms are overwhelmed.

Explanation:

Homeostasis, is the maintenance of a normal internal environment, in the face of external and internal disturbances, so that the functions of cells and systems of the body are preserved. This is accomplished primarily through feedback systems, so when a system is disturbed, a diversity of local responses, systemic reflexes (rapid reactions and automatic stimuli) and long-term adjustments are activated to bring the system back to its normal equilibrium point.

Most systems are controlled by negative feedback mechanisms, with the controlled variable being able to "turn off" its release, in the same way as a thermostat controls the temperature of a room. So, in this context, too much positive feedback would be related to harmful effects, such as homeostatic imbalance.

A gene on a chromosome lies close to another gene controlling a different trait. This indicates that the genes are _. The first
umka2103 [35]

My guess:

I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.

I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).

Hope it helped,
