Answer:

D. By blocking fish migration.

Explanation:

The pictured waterfalls are artificial.

The construction of the wall to raise water level for the falls to be created cuts the contact between marine organisms.

The fish on the other end of the fall cannot freely migrate to the other side.

This is because the falls are too dangerous for them and can lead to their death.

This means that the pictured method of power generation is not environmental friendly.

In a population of grasshoppers, the color green (G) is completely dominant over the color brown (g). If 23% of the population i
barxatty [35]
The answer is 49.92%

Let's use the <span>Hardy-Weinberg principle:
p + q = 1
p</span>² + 2pq + q² = 1
<span>
where:
p - the frequency of dominant allele G
q - </span>the frequency of recessive allele g
p² - the frequency of homozygous dominant individuals GG with colour green
2pq - the frequency of heterozygous individuals Gg with colour green
p² - the frequency of homozygous recessive individuals gg with color brown

23% of the population is brown: p² = 23% = 0.23
p = √(p²) = √0.23 = 0.48

p = 0.48
p + q = 1
0.48 + q = 1
q = 1 - 0.48 = 0.52

<span>The percentage of the population that is expected to be heterozygous is 2pq:
2pq = 2 * p * q = 2 * 0.48 * 0.52 = 0.4992 = 49.92%</span>

Explain have a fats sugars and or starch contained in seeds or milk are useful for the plant sprouting from the seed or the baby
Kipish [7]
There is a lot of calories in fats that can be a good help and can be used for growth, fats are high energy molecules that help in growing organism. Fats produces carbon dioxide, water, and ATP when metabolism.  The sugars and or starch is useful in the same method, they provide calories necessary for a seed or baby animal to grow. The sugars used in glycolysis and then the products of glycolysis used in  the citric acid cycle, and the starch can be cleaved into more manageable sugars.

elena-14-01-66 [18.8K]
The technicians ask the patients if they have any steel inside their body because the steel when subjected to a magnetic field they will become a magnet. since MRI produces a very large amount of magnetic field during its operation, then the still will be a magnet and it might hurt you
