In an ecosystem, available energy A. Diminishes at each successive tropic level.
The correct answer is C) NaOH
The correct answer is d: '<span>the protective coats of both groups are made of chitin'
Chitin is </span><span>a long-chain </span>polymer <span>derivative of </span>glucose, with a structural function in various groups of animals and plants, such as <span>of </span>cell walls<span> of </span>fungi<span>, </span>exoskeletons<span> of </span>arthropods <span>and the scales of </span>fish. It can be compared in function to keratin found in our hair and nails.
D.) These features may aid in the plant's reproduction
<u>Plant reproduction is the process by which plants generate new individuals. The fact that the plants have developed blue flower petals and a place for bees to land is an example of the aiding in the plants reproduction. </u>
1. Non random mating
In genetic equilibrium individuals must mate at random. However, in many species, individuals select mates based on heritable traits, such as size, strength, or coloration, a practice known as sexual selection.
2. Small population size
Genetic drift does not have major effects on large populations but can affect small populations. Thus evolutionary change due to genetic drift happens more easily in small populations.
<span>3. Immigration or Emigration
Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.
4. Mutations
Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.
5. Natural Selection
if different genotypes have different fitness, genetic equilibrium will be disrupted, and evolution will occur.</span>
