Ugo [173]

Answer: The diagrams above show an area that <u>was once a pasture</u> that has since undergone changes to the <u>vegetation </u>over time.

The following changes in the <u>hydrologic cycle</u> is most likely to occur as a result of the change in vegetation in the area:

  • Decreased precipitation.

Explanation:

When we <em>lose vegetation</em> in an area we face serious problems, one of them is the decreased precipitation . If changes are <em>made by man</em>, for example, as in deforestation, the consequences are <u>even worse.</u>

<u><em>Deforestation </em></u>can cause a serious <u>reduction of rainfall</u> in the tropics, with serious consequences for the population not only in that region but in <em>neighboring areas.</em> The air that passes over large areas of tropical forest produces at least twice as much rain as that which travels over areas of low vegetation .

In turn this also <u>affects the other factors</u> of the cycle. The vegetation <em>contributes</em> moisture through an <em>evapotranspiration process</em>, as it is called the evaporation of the rivers together with the transpiration of the plants. This moisture is transported by the winds.

We can say then that <u><em>the loss of vegetation</em></u> in an area (whether on purpose or not) <u><em>will corrupt several cycle factors</em></u>, mainly damaging the rainfall rate.

In a certain population of fruit flies, 640 out of 1000 have red eyes, while the remainder have sepia eyes. The sepia eye trait
irga5000 [103]

Answer:

The correct answer is 160.

Explanation:

Based on the given question, the total number of fruit flies is 1000, of which red eye flies are 640. Thus, the number of sepia eye flies will be 1000-640 = 360.  

On the basis of the Hardy-Weinberg equation, p+q = 1, in which p is the rate of recurrence of one allele, that is, dominant and q is the rate of recurrence of the other allele, that is, recessive.  

q^2 for the population is 360/1000 = 0.36, q = 0.6.  

Therefore, p = 1-q = 1-0.6 = 0.4.  

The frequency of homozygous dominant allele is denoted by p^2 = 0.16.  

Hence, the number of homozygous dominant for red eye color would be 16% of 1000 which will be equal to 160.
