Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
<h3>What are the effects of irrigation agriculture on river basins?</h3>
Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

D. Ligaments are strong and flexible bands of connective tissue that holds bones together meeting at a point known as joints. The first option - tendons - is also a connective tissue but they attach muscle to the bone.
Answer:
q = 0.42
Explanation:
This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;
p + q = 1
p² + 2pq + q² = 1
where;
p = the frequency of the dominant allele
q = the frequency of the recessive allele
p² = the frequency of individuals with homozygous dominant genotype
2pq = the frequency of individuals with heterozygous genotype
q² = frequency of individuals with the homozygous recessive genotype
Since the total population = 425
q² = 
= 
q² = 0.1765
To find q; we need to square root both side to eliminate the square from q².
∴ 
q = 0.4201
q = 0.42 (to two decimal places)
The correct option is A.
Proactive interference refers to the tendency of the knowledge that one had learned previously to prevent one from subsequent learning. Thus, proactive interference is the difficulty that comes with learning new things due to the stuffs that one had learned before. For instance, an individual may find it difficult to learn Spanish because he has previously learn German.<span />
