The types of design include repeated-measures, independent-groups, and matched pairs design.

Annotated bibliography provides specific information about each source you've used. As a researcher you have become an expert on your topic: you have the ability to explain the content of your sources, assess the usefulness, and share this information with others who may be less familiar with them.

Annotated bibliography is a list of citations to books, articles and documents.

Doss [256]

Answer:

38

Explanation:

  • Sexual reproduction happens when there is the involvement of two parents to give rise to the offsprings.
  • For the production of offsprings, each of the parents produces a haploid gamete and it is by the fusion of these two haploid gametes that a diploid organism is produced.
  • In the given situation, there are 19 chromosomes present in the haploid gametes this means that a diploid individual will have 2X19 = 38 chromosomes.
  • Now the underground stem cells are not gametes but somatic cells and the somatic cells are diploid and hence, they will have 38 chromosomes.

Describe how succession can help restore the equilibrium of an ecosystem.
lara [203]
Ecological succession is a process of inhabiting a zoological area by a group of organisms. it involves many stages to reach the climax stage such as primary, secondary, tertiary names basing on the habitat where it occurs. once the organisms reach the most stable stage of the succession. thus it maintains equilibrium

Succession helps restore the equilibrium of an ecosystem by forming up new species, diversifying species, and basically by replacing the damaged, deranged, or disturbed community. For instance, when a sudden climate change occurred in a community, such as drought, dryness, fire, or heat waves, all living things that depends on water or survives in a cool, wet environment will die or migrate somewhere else. Thus, leaving that community vacant and/or unoccupied by any living things. Succession, then, will take place in that area by going through various stages until reaching the climax stage, in which the ecosystem is complete again. c: hope i helped :D
