Match these terms with their descriptions

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 - internal combustion engine. Internal combustion engines release fumes of carbon monoxide.

3. fly ash of soot in air - coal-burning power plant. Coal burning plants release ash produced in small dark flecks.

4. soil contamination of water resources - DDT spraying in agriculture. DDT washes off agricultural land into water resources.

5. sewage contamination of water resources -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 - phosphate detergents. In many rivers, algal growth is limited by phosphate. Once excess phosphate is released to rivers, exponential algal growth can occur.

7.reduces farmland and plant life to cleanse air - urban sprawl. Urban sprawl uses up land for houses in an inefficient manner that could have been used for farming or natural areas.

8. studies air,water, and land - ecologist. Ecology is the study of relations of organisms to one another and to their physical surroundings.

Dengue fever is an infectious disease of humans that is caused by a virus. There are four main viral strains, and an individual

Yuri [45]

Answer:

Explanation:

Suppose the four different strains are P, Q, R, S. Thus, the first infection can be from any of the four strains and it occurs in 4 ways.

Since an individual cannot be infected again with the strain from which he/she is been previously infected;

Then, at the second time;

The possible number of strain to be infected with = 4-1 = 3 ways

Thus; the number of possible different levels of severity can be viewed by forming two lettered word P, Q, R, and S without repetition which is:

= 4 × 3

= 12

In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh

bixtya [17]

Answer: 60%

Explanation:

In population genetics, the Hardy-Weinberg Principle states that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors are active and no mutations occur.

The frequencies of the genotypes of an individual locus will be set to a particular equilibrium value. It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus. In the simplest case, with a locus with two alleles A and a, with allele frequencies of p and q respectively, the principle predicts that the genotypic frequency for the dominant homozygous AA is p^2, that of the heterozygous Aa is 2pq and that of the recessive homozygous aa, is q^2. The allele frequency of a is represented as p and the frequency of recessive allele is q.

The three genotypes AA : Aa : aa appear in a ratio p² : 2pq : q². If we add them up, we get the unit:

p^2 + 2pq + q^2 = (p + q)^2 = 1

And p + q = 1

Rh-positive genotypes are represented as AA (homozygous dominant) or Aa (heterozygous) since the presence of a single dominant allele is sufficient to express the phenotype. While Rh-negative genotypes are represented as aa.

If 84% of the population is Rh-positive, that means that this percentage includes all those who are AA and Aa. Then 16% are aa.

F(aa)=q^2=0.16

then F(a)=q=0.4

And since p + q = 1, p + 0.4 = 1, then p is 0.6

We can also calculate the rest, then F(AA)=p^2= 0.36

So F(Aa)= 2pq = 2 x 0.6 x 0.4 = 0.48

Notice that 0.36 + 0.16 + 0.48 = 1
