Water, sunlight, and carbon dioxide
-10grade/week
Explanation:
Given parameters:
Initial grade = 95grade
Final grade = 65grade
Time = 3weeks
Unknown parameter:
Rate of change of grade = ?
Solution:
Rate is defined as the change of a quantity with time.
Rate of change of grade = 
Rate of change of grade =
= 
Rate of change of grade = -10grade/week
The rate of change of the student's grade is -10grade/week. It implies that the grade of the student reduces by 10unit per week.
1. water temperature of lakes and rivers rise - nuclear power plant. Water is used as a coolant to maintain the temperature of nuclear reactors. and the resulting water is warmed up.

2.carbon monoxide pollutes air - </span> internal combustion engine. Internal combustion engines release fumes of carbon monoxide.

3. fly ash of soot in air - </span>coal-burning power plant. Coal burning plants release ash produced in small dark flecks.<span>
4. soil contamination of water resources - </span>DDT spraying in agriculture. DDT washes off agricultural land into water resources.

5. sewage contamination of water resources -</span>population density. Urban areas produce a low of sewage, which is usually treated before being disposed of in rivers or the sea.

6. excess plant growth in the lakes or rivers - </span>phosphate detergents. In many rivers, algal growth is limited by phosphate. Once excess phosphate is released to rivers, exponential algal growth can occur.<span>
7.reduces farmland and plant life to cleanse air - </span>urban sprawl. Urban sprawl uses up land for houses in an inefficient manner that could have been used for farming or natural areas.

Answer:
The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.
Explanation:
This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.
According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.
This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
