The best option is D. Based on scientific evidence about algal bloom, it would be best to evacuate all humans from the area around the lake. Algal bloom is caused by excess nutrients in the lake. This occurrence is linked to the death of fishes, plants, mammals and birds. Also. it has been said to cause human illnesses. Thus, to avoid this, it would be best to stay away from the lake with algal bloom.
Answer:
Explanation:
A keystone species is the one which plays an important role in maintaining the structure of the ecosystem. On the keystone species many other species of the ecosystem are dependent upon.
The potential effects associated with the keystone species includes the following:
1. No other species will be capable of filling the same ecological niche. Hence, the dependent organisms will suffer and the ecosystem will change drastically.
2. The ecosystem will be populated by the invasive species which will affects the population of native species.
Answer:
I think the answer would be C
Cadaver Decomposition Island
- When a body is buried directly in the soil, then it is subject to decomposition by insects and microorganisms.
<span>- </span>During this process, a self-digestion of the cells occurs as well as anaerobic decomposition of animal proteins resulting in a release of various chemical components.
<span>- </span>This nutrient-rich fluid is trapped in the soil matrix for a long period of time resulting in the formation of Cadaver Decomposition Island
<span>- The formation of Cadaver Decomposition Island is associated with increased microbial biomass and activity.</span>
Answer:
The right order is
incomplete dominance ==> 2
polygenic inheritance ==> 3
codominance ==> 1
Many physical characters depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
Codminance: The phenotype of each allele is expressed simultaneously in heterozygotes.
Incomplete Dominance: An intermediate phenotype is obtained between the two dominant alleles.
