Answer:

The correct option is B) adaptation

Explanation:

The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.

How would you write this number in scientific notation? (Use the carrot key to denote an exponent. ex: 6.02 x 10^23)

NeTakaya

Answer:

$D=5.89\times 10^{12}\ km$

Explanation:

The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.

A number can be written as $x.0\times 10^y$ in scientific notation where x is a real no and y is any integer.

There are 10 zeros in the given number and also there are 12 digits after. It would mean that,

$D=5.89\times 10^{12}\ km$

So, the distance in scientific notation is : $D=5.89\times 10^{12}\ km$

What is the name of the oxidized form doesn't have h attached of the electron carrier in photosynthesis?

KiRa [710]

In photosynthesis, an electron carrier of the light cycles is the nicotinamide adenine dinucleotide phosphate or NADP. This is the oxidized form, because the reduced form of this carrier has the extra H (NADPH). This is somehow related to the electron carrier called nicotinamide adenine dinucleotide or NAD (minus the phosphate).

A regional lobster management board recently proposed a five-year moratorium on lobster fishing in the Atlantic waters south of

Ierofanga [76]

Answer:

Statement D is not correct.

Explanation:

a. Lobsters are rival but not excludable: This is correct, as lobster is a common resource to which everybody can get access to with no need to pay for it. Besides, a person can consume only one animal.

b. The lobster population is an example of the tragedy of the commons: This is correct, since people, acting by their own needs or interests, may exceed the capture of too many lobsters, affecting their population and, therefore, other users.

c. Reducing the quota on the number of lobsters any fisher can catch would have a protective effect on the lobster population: This is correct, since reducing the number of lobster catches will allow the animal population to reproduce more, leaving offspring capable of reaching sexual maturity, mating and reproducing again, and thus increasing the population size and stabilizing it.

d. If left unregulated, the lobster population will likely increase: This is not correct. There need to be some regulation or management, because if not these animals will continue to be caught, even in the reproductive season, not allowing the population to stabilize. In this case, the population will likely decrease, rather than increase.

Describe how a disturbance changed forest ecosystems near Mount St. Helens

Sholpan [36]

At Mount St. Helens, erosion cut through the new volcanic deposits and exposed soil where plants could sprout. Thus in this disturbance, erosion was a positive process for plants, improving habitat. Lakes, streams, and forests responded at different rates after the 1980 eruption.
