Answer:
In the crossing of two hybrid plants for the color flowers trait can be seen that the phenotypes are purple flowers and white flowers and in the descendants the phenotypes, genotypes and probabilities are purple flowers Bb (50%), purple flowers BB (25%) and white flowers bb (25%).
Explanation:
For the flower color trait, the dominant allele is purple (B) and the recessive allele is white (b). The planted cross shows two purple hybrid flowering plants (Bb) and the offspring can be seen in Punnet square:
<u>Crossing: Bb X Bb
</u>
Alleles B b
B BB Bb
b Bb bb
The results in the offspring are:
- <em>Plants with purple heterozygous flowers Bb 50%.
</em>
- <em>Plants with pure purple flowers BB 50%.
</em>
- <em>Plants with white flowers bb 25%.</em>
FalseWith as low as 0.02 percent blood alcohol reading, moderate
effects can be felt and a weakened ability to focus on more than one thing a
time is apparent. For men weighing 160-240
pounds and women 200-240 pounds, impairment begins with 0.02 percent blood alcohol.
Answer:
1) If a pesticide was used to kill the grasshoppers and the caterpillars, then the frogs should be fine, because the pesticide isn't made to effect them; also, unless their diet was only of grasshoppers and caterpillars, then the frogs would not starve.
2) Two human activities that can impact the ecosystem are, pollution, and deforestation. Pollution, because it can harm animals, but against popular (but unscientific) belief, doesn't cause climate change. Deforestation also harms animals, and also causes for some trees to have to produce more oxygen than before.
3)Life on earth could not exist on earth without plants and decomposers because there would be no oxygen left on earth for creatures to breathe, and there would be no nutrients to keep the earth alive.
