Human impact from the use of fertilizers can significantly disrupt the nitrogen cycle, leading to imbalances in ecosystems and potentially causing environmental issues.
Fertilizers, especially synthetic nitrogen-based fertilizers, contain compounds like nitrates that are highly soluble in water.When excess fertilizer is applied to fields, gardens, or lawns, rainwater can wash away the nitrates into nearby water bodies through a process called runoff.
This runoff can lead to eutrophication, a condition where excessive nutrients, including nitrates, stimulate the overgrowth of algae in water bodies. The algae then consume oxygen as they decompose, leading to oxygen depletion and negatively impacting aquatic life.

A continuation of this will have what immediate impact on the local ecosystem?
Answer:
Understanding the status and trends of ecosystem services (ES) in a changing environment is important for identifying effective management measures of multifunctional mangrove ecosystems. Mangroves and their ES are jeopardized by a complex set of factors, with impacts that are experienced at local levels, especially in developing countries, where people often rely directly on natural capital for their livelihoods and well-being. This study was set to explore how local communities in the Rufiji Delta, situated in central coastal Tanzania, perceived the status and trends in mangrove ecosystem services (MES), associated drivers of change and the impacts of changes in MES on local livelihoods. A mixed methodological framework (including focus group discussions, key informant interviews, household surveys and direct observations) was used. People from villages close to mangroves rated the status of MES higher than those in villages distant from mangroves. Provisioning services (P) were often perceived to be in a worse and more declining state than regulating (R), cultural (C) and supporting services (S). A decrease in availability of poles and firewood (P), decline of fish habitats (S) and an increase in education value (C) were the most commonly perceived changes of MES in the study area. Illegal harvesting of mangrove poles, rice cultivation, climate change and inadequate management were seen as the most critical drivers of mangrove degradation, although the perceptions differed between sites. Rice farming was perceived to be a primary cause of mangrove loss by communities far from mangrove forests, while illegal exploitation was identified as the major driver by communities near mangroves. Fishing, collection of poles and honey were perceived as the most impacted livelihoods depending on MES. This together with the comparatively low status and declining trend of these MES indicate that they should be of high management priority as indicated by the first order management index used in this study.

The pattern observed when a heterozygote does not show the trait associated with the dominant allele is
Co-dominance will make the pattern expected for the dominant allele to control the observed trait not to occur.
What is allele?Genes occur in pairs. These pairs of genes determine which traits are expressed in an organism. The allele has a dominant gene and a recessive gene.
Sometimes, the pattern that is expected in which the dominant gene is expressed is not observed due to codominance.

In man, hitchhiker's thumb is domiant to a straight thumb, and brown eyes is dominat to blue eyes. If a man that has a straight thumb and brown eyes in the heterozygous form marries a woman that is heterozygous for hitchhiker's thumb and blue eyes, what is the chance that one of their children will have a straight thumb and blue eyes?
Answer:
25%
Explanation:
T = Hitchhiker's thumb
t = straight thumb
B = Brown eyes
b = blue eyes
The man's genotype is ttBb
The woman's genotype is Ttbb
Make a dihybrid punnett square to find the possible genotypes of the offspring
ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:
Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype
4 ÷ 16 = 0.25
0.25 × 100 = 25%

Explanation:
Describe the process that causes the cloud type
shown to reach heights of over 6000 m.
Answer:
Explanation:
Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.
