<u>Answer:</u>
In ecology, catastrophes permanently alter the physical structure of the existing environment.
<u>Explanation:</u>
- The ecological disturbances include flood, strom, plague, fires, earthquakes, tsunami, volcanic eruptions, climatic change and impact of humans on the environment like deforestation ,nuclear testing etc.
- These factors can have a visible impact on the structure of the earth and permanently alter the environment.
- The visible effects of these disturbances are global warming, extinction of selective species, change in the course of rivers, submergence of coastal areas, sudden movement of the tectonic plates and formation of sudden cracks on the earth's crust.
Macromolecules like carbs, protein and lipids (fats) are made of smaller molecules like simple sugars (carbs), amino acids (protein), or fatty acids (lipids). These molecules must be broken down to be used.
Let me know if you need further elaboration, I took human nutrition last semester. :)
Answer:
The frequency of blue eyes in population 2 after the migration is q₂´ = 0.195 ≅ 0.2
Explanation:
Whenever migration, m, occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.
For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.<u>

<u>Available data:</u>
- Population 1 → frequency of the recessive allele b = 0.3
- Population 2 → frequency of the recessive allele b = 0.15
- m = proportion of gametes coming from the population 1 = 30% = 0.3
- <em>1-m = proportion of gametes that remain in the population</em>
- <em>p = frequency of the dominant allele in population 1 before migration</em>
- <em>q = frequency of the recessive allele in population 1 before migration</em>
- <em>p´ = frequency of the dominant allele in population 2 after migration</em>
- <em>q´ = frequency of the recessive allele in population 2 after migration</em>
To calculate the frequencies of the gametes (p1, q1, p2, q2) after migration, we can use the following equations:
- p₁’ = p₁ (1 - m) + p₂ x m
- q₁´ = q₁ (1 - m) + q₂ x m
- p₂’ = p₂ (1-m) + p₁ x m
- q₂´ = q₂ (1 - m) + q₁ x m
So to know the frequency of blue eyes in population 2 after the migration, we just need to replace the terms in the equation for the given values, and then calculate q₂´.
q₂´ = q₂ (1 - m) + q₁ x m
q₂´ = 0.15 (1 - 0.03) + 0.3 x 0.3
q₂´ = 0.105 + 0.09
q₂´ = 0.195 ≅ 0.2
Answer:
b.) because its the only thing he can really control and it stays the same through out the entire experment
Explanation:
Answer:
The answer is c because A and B are not really giving off an imporant feeling to why carbon is important and D if you read the question carefully it says abundant which means to be a lot of, so C would be your answer
and plus i did the test
