An abiotic organism is nonliving. A biotic organism is living.
The genetic information from DNA is transcribed into mRNA which is translated into polypeptide. The genetic information of mRNA is translated into polypeptide.
mRNA:
5'-AUG GUG CAC CUG ACU CCU GAG GAG AAG UCU GCC GUU ACU -3'
Translated polypeptide:

In some plants, pink flowers are dominant over yellow flowers. If Marlo crosses two hybrids _____.
the ratio of pink to yellow flowers will be 3:1
50 percent of the offspring will be hybrids
none of the offspring will have yellow flowers
three-fourths of the offspring will have the same phenotype
half of the offspring will be homozygous for flower color
Answer:
A) option B, two homozygous recessive plants is correct
B) A, B, D and E is correct
Explanation:
A) Given purple flowers are dominant over white flowers
Let P represents allele for purple color of flower while p represents white color of flower.
In order to create all white offspring from a cross, the parents must have homozygous recessive genotype i.e pp
Hence, option B, two homozygous recessive plants is correct.
B) Given pink flowers are dominant over yellow flowers. Let “Y” represents allele for pink flower and “y” represent allele for yellow flower
If two hybrid parents with genotype “Yy” are crossed, then following offspring will b eproduced –
Yy * Yy
YY, Yy, Yy, yy
Out of four , two are hybrid offspring, three genotype i.e YY, Yy, Yy have the same genotype and both YY and yy are homozygous for flower color,
Hence, option A, B, D and E is correct.
Answer:
Groundwater protection must be a high priority in zones where contamination can easily enter the aquifer and affect a spring or pumping well used for the drinking water supply of a large population.
Explanation:
Groundwater protection has been addressed in most countries by issuance of different rules and regulations at national or local level that aim at preventing aquifer contamination. In this sense, laws have been issued to regulate the use and manufacture of toxic products, and set measures to manage the waste produced by industrial activities, and to properly place and maintain waste disposal and storage facilities (landfills, injection wells, storage tanks). Maximum allowable concentrations for some pollutants have been established, mainly in developed countries, to preserve a good quality of the groundwater exploited for drinking water supply. In addition, well-head protection areas and groundwater zone protection areas have also been defined in some developed countries to prevent pollution of drinking water sources.
