Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.
The answer is; B
Not all disturbances to ecosystems are undesirable. The fact, however, is that disturbance does change the structure of the ecosystem including impacting the biodiversity. The disturbance may benefit some species while it may be disadvantageous to some species. An example is that while a volcanic eruption might devastate a whole ecosystem, the recovered ecosystem after time may have an increased biodiversity than before.
The answer to 1 and 2 is
fishing using cyanide and dynamite, pollution from sewage and agriculture, massive outbreaks of predatory starfish, invasive species.
Answer:
The correct answer is - wobble; the curvature of the anticodon loop; inosine.
Explanation:
The wobble phenomenon or hypothesis tells that why there are multiple codons are present for a single amino acid. 20 amino acids are coded by 61 codons. It states that tRNA can identify and attach to more than one amino acid due to the curvature of the anticodon loop.
The curvature of the anticodon loop is that the base at the 1st position on the anticodon to binding but the less-precise base pairs that can arise between the 3rd base of the codon. The inosine is the nucleoside that presents in a position in the curvature of the anticodon loop and its position responsible for wobble as well.
Food chains don’t have infinite links, because only about 10% of energy is passed upwards in trophic levels. So a mouse could eat 10 grasshoppers, but a hawk would need to eat 100 mouses to get the same energy
