What did Darwin notice about life on the Galápagos Islands?

Answers

Answer 1
Answer: 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.
Answer 2
Answer: 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.

In experiments testing the cocktail party effect, most participants were unable to do any of the following except _____________.A.
detect when the speaker’s voice changed from male to female
B.
identify any phrase associated with the unattended information
C.
detect when the unattended language was changed to German
D.
notice specific changes when the unattended speech was played backward

Answers

Answer:  C. detect when an unattended language was changed to German.

The cocktail party effect refers to ability of a person to focus on a single speaker or conservation in a noise prone area. This mainly reflects listening ability of the person in a noisy environment. If a listener hears unattended language for a particular time along with noise.The listener may loose interest  in listening and he will not show alertness when language changes to German which could be known language to listener.

Final answer:

In experiments testing the cocktail party effect, most participants were only able to detect when the speaker’s voice changed from male to female, illustrating the selective nature of our auditory perception.

Explanation:

The cocktail party effect is a psychological phenomenon where one can focus their auditory attention on a specific source while filtering out other background noises. This effect is named after a scenario of a cocktail party where one can focus on a single conversation in a noisy room. In experiments testing this effect, most participants were able to do one specific thing from the options given: that is, option A. detect when the speaker’s voice changed from male to female.

Participants found it hard to perform all the other tasks given. This is because the 'unattended' information in the auditory scene was not being processed to the point where the participants could identify phrases (option B), notice language changes (option C), or detect specific changes when the speech was played backward (option D). This highlights the selective nature of our auditory perception.

The roots of the aquatic plant hydrilla are poorly developed and lack xylem tissue. Which is an appropriate justification for this? 1.As hydrilla is aquatic in nature, the roots do not have to search for oxygen, and there is no need for xylem to absorb oxygen because the plant is surrounded by water that has dissolved oxygen in it. 2.As hydrilla is aquatic in nature, the roots do not have to search for minerals,and there is no need for xylem to absorb nutrients because the plant is surrounded by water that has dissolved nutrients in it
3.As hydrilla is aquatic in nature, the roots do not have to search for water, and there is no need for xylem to absorb water because the plant is surrounded by water.

Answers

The appropriate justification of this is that B. As hydrilla is aquatic in nature, the roots do not have to search for minerals, and there is no need for xylem to absorb nutrients because the plant is surrounded by water that has dissolved nutrients in it. 

Answer:

B

Explanation:

The Eurasian water milfoil is a nonnativespecies, which was once commonly sold as an
aquarium plant, and is now found growing in
many lakes in New York State. It has few
natural enemies, and grows rapidly, crowding
out many native species. This plant ruins fishing
areas and interferes with boating and other
water sports. This is an example of
(1) human consumption of finite resources
(2) an unintended consequence of adding an
organism to an ecosystem
(3) an abiotic factor having a negative effect on
an ecosystem
(4) the introduction of a species that has
increased the long-term biodiversity of an
ecosystem

Answers

The right answer for the question that is being asked and shown above is that: "(4) the introduction of a species that has increased the long-term biodiversity of an ecosystem." This plant ruins fishing areas and interferes with boating and other water sports. This is an example of the introduction of a species that has increased the long-term biodiversity of an ecosystem

Answer:

it would be (2) or B

Explanation:

Because if the plant is commonly sold as aquarium plants then they could have had an unintended consequence of adding an organism to an ecosystem.
