houses have been built around a small retention pond, increasing the fertilizer runoff into the pond. This has led to algal bloo
Andrei [34K]

<span>Algae blooms are the consequence of large amounts of fertilizers in the water. Algae use the presence of increased nutrients and enhance their own growth. It is known that they produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This could lead to the death of aquatic animals that depend on oxygen. So, in the population will survive only those who are able deal with the lack of oxygen in the water</span>

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferenc
Komok [63]

Answer:

c

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency

Chamber         O                    E             Chi-square

  A                   18                   10             \frac{(18 - 10)^2}{10} = 6.4

  B                    2                    10             \frac{(2 - 10)^2}{10} = 6.4

<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8

<em>Degree of freedom</em> = 2 - 1 = 1

<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

<em>The correct option is </em><em>c</em><em>.</em>

Genetically-modified organisms (GMOs) have included corn crops engineered to produce a natural pesticide to kill a certain insec
Dmitrij [34]
A downside to this mutant corn wohld be that it would give rise to a presticide-immune strain of the certain insect.

All the non-immune bugs would die, leaving the few immune ones to reproduce. That would result in a overpopulation of immune super-bug that would still be able to go ham on the large, GMO corn, like nothing happened, and still go on to affect native plant populations. That can become a huge problem.

Hope that helped!
